Role of glutaminyl-peptide cyclo-transferase-like protein (QPCTL) in cancer: From molecular mechanisms to immunotherapy.

Glutaminyl-peptide cyclotransferase-like protein (QPCTL) is a newly discovered enzyme that has sparked interest owing to its possible role in cancer genesis and progression. Initially discovered as a post-translational modification regulator of protein maturation, QPCTL has emerged as a key participant in cancer biology. Recent research has linked QPCTL to numerous essential cancer-related processes, including cell proliferation, migration, invasion, and apoptosis. Furthermore, QPCTL expression changes have been seen in a variety of cancer types, underlining its potential as a diagnostic and prognostic marker. The molecular mechanisms behind QPCTL's participation in cancer will be examined in this review. We investigate its involvement in the control of signaling pathways and the modification of cellular activities that are important in cancer. We also examine the clinical importance of QPCTL, including as its relationship with tumor development, metastasis, and response to treatment. We also discuss the possible therapeutic implications of targeting QPCTL in cancer therapy. QPCTL is a prospective target for the development of innovative anticancer treatments due to its participation in several cancer-associated pathways.

Unveiling RACK1: a key regulator of the PI3K/AKT pathway in prostate cancer development.

The dysregulated PI3K/AKT pathway is pivotal in the onset and progression of various cancers, including prostate cancer. However, targeting this pathway directly poses challenges due to compensatory upregulation of alternative oncogenic pathways. This study focuses on the novel regulatory activity of the Receptor for Activated Protein Kinase (RACK1), a scaffolding/adaptor protein, in governing the PI3K/AKT pathway within prostate cancer. Through a genetic mouse model, our research unveils RACK1's pivotal role in orchestrating AKT activation and the genesis of prostate cancer. RACK1 deficiency hampers AKT activation, effectively impeding prostate tumor formation induced by PTEN and p53 deficiency. Mechanistically, RACK1 facilitates AKT membrane translocation and fosters its interaction with mTORC2, thereby promoting AKT activation and subsequent tumor cell proliferation and tumor formation. Notably, inhibiting AKT activation via RACK1 deficiency does not trigger feedback upregulation of HER3 and androgen receptor (AR) expression and activation, distinguishing it from direct PI3K or AKT targeting. These findings position RACK1 as a critical regulator of the PI3K/AKT pathway and a promising target for curtailing prostate cancer development arising from pathway aberrations.

Homeotic <I>DUX4</i> genes shape dynamic inter-chromosomal contacts with nucleoli in human cells

Nucleoli shape inter-chromosomal contacts with genes controlling differentiation and cancer genesis. DUX4 genes specify transcription factor possessing two homeodomains. Previously, using Circular Chromosome Conformation Capture (4С) approach on population of cells, it was demonstrated that DUX4 gene clusters form frequent contacts with nucleoli. It was found also that these contacts are almost completely abolished after heat shock treatment. 4C approach as all ligation-mediated methods is capable to detect rather close interactions between chromatin loops in nuclei. In order to independently confirm the formation and the frequency of the contacts in single cells we used FISH approach. Here, we show that DUX genes in single cells form stable contacts in all tested HEK293T cells. The contacts after heat shock treatment reversibly retreat up to 1–3 μm distance. We conclude that inter-chromosomal contacts shaping by nucleoli are dynamic and stable providing both the initiation and maintenance of a differentiated state.

New Insights into Colorectal Cancer through the Lens of Precision Oncology and Personalized Medicine: Multi-Omics Helps Aging of Predisposed People.

Recently, there has been a significant evolution in our understanding of the molecular pathways causing the genesis and progression of cancer via the inter-individual variations. Thus, one-size-fits-all methods for cancer treatment have been replaced by precision oncology (PO) targeting individual cancer symptoms, offering increased effectiveness, and decreased safety concerns and cost load. The identification of novel actionable indications, rapid, precise, and comprehensive detection of complex phenotypes in every individual, pioneering clinical trial projects with enhanced response feedback, and widespread availability of innovative targeted anticancer management for every patient are vital for the effective implementation of next-generation precision oncology. Additionally, the emergence of precision medicine has altered the perspective of oncologic biomarkers, drug discovery, drug development, and, improvements for cancer patients. This paper narratively reviewed to identify actionable abnormalities, Genomic profiling of tumors employing clinical next-generation sequencing (NGS) from both tumor tissues and liquid biopsies along with the multi-omics strategies as the key component of PO. Our increasing information on tumor biology, specifically microenvironment and heterogeneity- associated data, would improve our understanding of the resistance of targeted drugs and specific mechanisms of action, as well as help enhance existing metastatic colorectal cancer (mCRC) treatment strategies. Collectively, this paper indicated the current and innovative strategies for prognosis, diagnosis, and treatment of various cancer types based on PO overview with a groundbreaking emphasis on CRC suggesting the integrations of multi-omics, highlighting Genomics, and utilizing AL and ML algorithms with targeted therapies. Notably, these findings can help improve the life-span and ageing of the predisposed people.

NCAPD3 is a prognostic biomarker and is correlated with immune infiltrates in glioma.

Non-SMC Condensin II Complex Subunit D3 (NCAPD3) has been linked with the genesis and progression of multiple human cancers. Nevertheless, the scientific value and molecular process of NCAPD3 in glioma remain unclear. We explored the level of NCAPD3 expression in pan-cancer by multiple online databases. And we focused on the level and prognostic value of NCAPD3 expression in glioma by immunohistochemistry (IHC) and survival analysis. Meanwhile, we verified the relationship between NCAPD3, biological function and immune infiltration in glioma by Linkedomics and SangerBox databases. The expression of NCAPD3 was increased in a variety of cancers, including glioma. Its high expression was strongly related to WHO grade (P=0.002) and programmed cell death ligand 1 (PD-L1) expression of glioma (P=0.001). Patients with a high level of NCAPD3 expression had a lower overall survival (OS) in glioma than patients with a low level of NCAPD3 expression. Multivariate statistical analyses showed NCAPD3 expression (P=0.040), WHO grade (P<0.001), 1p/19q codeletion (P<0.001), recurrence (P<0.001), age (P=0.023), and chemotherapy status (P=0.001) were meaningful independent prognostic factors in patients with glioma. Furthermore, bioinformatics analysis proved that NCAPD3 has been linked to immune infiltration in glioma. High level of NCAPD3 expression may serve as a promising prognostic biomarker and correlate with dendritic cell infiltration, representing a potential immunotherapy target in glioma.

Germline mutations of TP53 gene can be a key factor in prostate cancer genesis

Aim: The aim of this study is to investigate whether germline alterations of exon 5 of TP53 gene could be detected in the blood of known men with prostate cancer and to assess the potential association between the genomic alteration affecting this gene and clinicopathological characteristics of the patients. Methods: Forty-eight blood samples from men diagnosed with prostate cancer were analyzed for TP53 germline mutations and confirmed by Sanger sequencing. The frequency and distribution of high-frequency mutations were analyzed according to the pathological criteria of the patients and a computational study was performed to assess the effect of new mutations. Results: The Sanger sequencing revealed that 79% of the population studied carry mutations in TP53 gene. In summary, a total of 137 mutations have been identified in this gene, out of which 115 are new mutations. Frameshift mutations were the most frequent; the mutation c.392delA was recorded in fifteen cases (31%); the mutations c.383delC and c.432delG were observed at a frequency of 12.5% and 10% respectively. The most frequent missense mutation was the variant c.502C&gt;A (p.His168Asn) identified in eleven patients (23%). One nonsense mutation was identified in one patient and resulted in a stop codon in position 126 (tyrosine). All codons affected by these alterations are part of the DNA binding domain of the protein TP53. Conclusions: The germline mutation frequency observed in prostate cancer patients, and the new mutations recorded in TP53 gene, could be in favor of a potential association of genomic alterations in this gene and prostate cancer genesis, thereby constituting a tool, similar to other genes in the DNA repair pathway such as BRCA1 and BRCA2. This could contribute to the advancement of diagnosis and therapeutic strategies for prostate cancer.

The immune microenvironment of cancer of the uterine cervix.

While several treatment choices exist for cervical cancer, such as surgical therapy, chemotherapy, and radiotherapy, some patients will still show poor prognosis. HPV infection is a principal factor for cervical cancer development, from early inflammation to proliferation, angiogenesis, and neoplastic growth. While HPV T-cell responses exist, the tumor seems to evade the immune system upon its tolerance. The latter suggests the existence of a confluent tumor microenvironment responsible for the evasion tactics employed by the neoplasm. Therefore, novel biomarkers governing prognosis and treatment planning must be developed, with several studies tackling the significance of the tumor microenvironment in the genesis, development, proliferation, and overall response of cervical cancer during neoplastic processes. This review aims to analyze and contemplate the characteristics of the tumor microenvironment and its role in prognosis, progression, evasion, and invasion, including therapeutic outcome and overall survival.

Caspase-Activated DNase localizes to cancer causing translocation breakpoints during cell differentiation.

Caspase activated DNase (CAD) induced DNA breaks promote cell differentiation and therapy-induced cancer cell resistance. CAD targeting activity is assumed to be unique to each condition, as differentiation and cancer genesis are divergent cell fates. Here, we made the surprising discovery that a subset of CAD-bound targets in differentiating muscle cells are the same genes involved in the genesis of cancer-causing translocations. In muscle cells, a prominent CAD-bound gene pair is Pax7 and Foxo1a, the mismatched reciprocal loci that give rise to alveolar rhabdomyosarcoma. We show that CAD-targeted breaks in the Pax7 gene are physiologic to reduce Pax7 expression, a prerequisite for muscle cell differentiation. A cohort of these CAD gene targets are also conserved in early differentiating T cells and include genes that spur leukemia/lymphoma translocations. Our results suggest the CAD targeting of translocation prone oncogenic genes is non-pathologic biology and aligns with initiation of cell fate transitions.

Effectiveness of surgical castration by bilateral subcapsular orchiectomy as monotherapy for the treatment of advanced prostate cancer.

Prostate cancer is the most common malignancy in men and the second cause of death due to cancer [1]. Treatment of prostate cancer has been a field of many progresses, but the discovery of the role of androgen in the genesis of prostate cancer by Hugins and Hodges is really a milestone in the treatment of advanced prostate cancer [2]. In patients with advanced prostate cancer, options for androgen ablation include bilateral orchiectomy, therapy with luteinizing hormone-releasing hormone (LHRH) analogues and antagonists, and combined androgen blockade (typically a LHRH analogue plus a first-generation anti-androgen). Although orchiectomy remains the historical gold standard for androgen ablation, LHRH therapy is considered to be equivalent therapeutically. Medical castration has the advantage to induce less psychological effects comparatively to the surgery, reason why in developed countries patients are managed with medical therapy [3]. However, LHRH agonists cannot induce a complete castration levels of testosterone in some patients [4]. Instead, surgical castration can completely eliminate remaining testosterone produced by the Leydig cells in testes [5]. According to the latest recommendations of the European Association of Urology (EAU), androgen deprivation therapy (ADT) is the firstline indication in patients with advanced and metastatic PCa [6]. This first line is made of LHRH agonists, surgical castration representing the second line [7] And Several techniques of surgical castration have been described with comparable results in terms of patient survival and quality of life, but the sub-capsular technique of preserving testicular albuginea and epididymis is the most commonly used [8]. The relatively high cost of chemical castration is a constraint in the therapeutic choice in developing countries [9]. Therefore, surgical castration is an interesting alternative because of its simplicity and affordability in patients, most of whom have no health insurance. In Togo, most patients diagnosed with prostate cancer are at the metastasis stage, and surgical castration is often used as first-line treatment [10]. The aim of this study was to assess the biological and clinical effectiveness of surgical castration as the sole treatment in patients with advanced prostate cancer.

RBM8A, a new target of TEAD4, promotes breast cancer progression by regulating IGF1R and IRS-2

BackgroundBreast cancer (BC) is the most common malignant tumor in women worldwide, and further elucidation of the molecular mechanisms involved in BC pathogenesis is essential to improve the prognosis of BC patients. RNA Binding Motif Protein 8 A (RBM8A), with high affinity to a myriad of RNA transcripts, has been shown to play a crucial role in genesis and progression of multiple cancers. We attempted to explore its functional significance and molecular mechanisms in BC.MethodsBioinformatics analysis was performed on publicly available BC datasets. qRT-PCR was used to determine the expression of RBM8A in BC tissues. MTT assay, clone formation assay and flow cytometry were employed to examine BC cell proliferation and apoptosis in vitro. RNA immunoprecipitation (RIP) and RIP-seq were used to investigate the binding of RBM8A/EIF4A3 to the mRNA of IGF1R/IRS-2. RBM8A and EIF4A3 interactions were determined by co-immunoprecipitation (Co-IP) and immunofluorescence. Chromatin immunoprecipitation (Ch-IP) and dual-luciferase reporter assay were carried out to investigate the transcriptional regulation of RBM8A by TEAD4. Xenograft model was used to explore the effects of RBM8A and TEAD4 on BC cell growth in vivo.ResultsIn this study, we showed that RBM8A is abnormally highly expressed in BC and knockdown of RBM8A inhibits BC cell proliferation and induces apoptosis in vitro. EIF4A3, which phenocopy RBM8A in BC, forms a complex with RBM8A in BC. Moreover, EIF4A3 and RBM8A complex regulate the expression of IGF1R and IRS-2 to activate the PI3K/AKT signaling pathway, thereby promoting BC progression. In addition, we identified TEAD4 as a transcriptional activator of RBM8A by Ch-IP, dual luciferase reporter gene and a series of functional rescue assays. Furthermore, we demonstrated the in vivo pro-carcinogenic effects of TEAD4 and RBM8A by xenograft tumor experiments in nude mice.ConclusionCollectively, these findings suggest that TEAD4 novel transcriptional target RBM8A interacts with EIF4A3 to increase IGF1R and IRS-2 expression and activate PI3K/AKT signaling pathway, thereby further promoting the malignant phenotype of BC cells.

Deciphering the code: the pivotal role of lncRNAs in advancing TNBC therapy.

Triple-negative breast cancer (TNBC) represents the most formidable subtype of breast cancer, characterized by a notable dearth in targeted therapeutic options. Deciphering the underlying molecular mechanisms of TNBC is pivotal for improving patient outcomes. Recent scientific advancements have spotlighted long non-coding RNAs (lncRNAs) as key players in the genesis, progression, and metastasis of cancers. This review delineates the significant influence of lncRNAs on the advancement, detection, and neoadjuvant chemotherapy efficacy in TNBC, detailing the diverse expression patterns of aberrant lncRNAs. The paper explores the specific mechanisms by which lncRNAs regulate gene expression in both the nucleus and cytoplasm, with a special focus on their involvement in TNBC's post-transcriptional landscape. Thorough investigations into TNBC-associated lncRNAs not only forge new avenues for early diagnosis and potent treatment strategies but also highlight these molecules as promising therapeutic targets, heralding an era of personalized and precision medicine in TNBC management.

Stressed? Break-induced replication comes to the rescue!

Break-induced replication (BIR) is a homologous recombination (HR) pathway that repairs one-ended DNA double-strand breaks (DSBs), which can result from replication fork collapse, telomere erosion, and other events. Eukaryotic BIR has been mainly investigated in yeast, where it is initiated by invasion of the broken DNA end into a homologous sequence, followed by extensive replication synthesis proceeding to the chromosome end. Multiple recent studies have described BIR in mammalian cells, the properties of which show many similarities to yeast BIR. While HR is considered as “error-free” mechanism, BIR is highly mutagenic and frequently leads to chromosomal rearrangements—genetic instabilities known to promote human disease. In addition, it is now recognized that BIR is highly stimulated by replication stress (RS), including RS constantly present in cancer cells, implicating BIR as a contributor to cancer genesis and progression. Here, we discuss the past and current findings related to the mechanism of BIR, the association of BIR with replication stress, and the destabilizing effects of BIR on the eukaryotic genome. Finally, we consider the potential for exploiting the BIR machinery to develop anti-cancer therapeutics.

Plasma metabolomics combined with mass spectrometry imaging reveals crosstalk between tumor and plasma in gastric cancer genesis and metastasis

Gastric Carcinoma (GC) is a highly fatal malignant tumor with a poor prognosis. Its elevated mortality rates are primarily due to its proclivity for late-stage metastasis. Exploring the metabolic interactions between tumor microenvironment and the systemic bloodstream could help to clearly understand the mechanisms and identify precise biomarkers of tumor growth, proliferation, and metastasis. In this study, an integrative approach that combines plasma metabolomics with mass spectrometry imaging of tumor tissue was developed to investigate the global metabolic landscape of GC tumorigenesis and metastasis. The results showed that the oxidized glutathione to glutathione ratio (GSSH/GSH) became increased in non-distal metastatic GC (M0), which means an accumulation of oxidative stress in tumor tissues. Furthermore, it was found that the peroxidation of polyunsaturated fatty acids, such as 9,10-EpOMe, 9-HOTrE, etc., were accelerated in both plasma and tumor tissues of distal metastatic GC (M1). These changes were further confirmed the potential effect of CYP2E1 and GGT1 in metastatic potential of GC by mass spectrometry imaging (MSI) and immunohistochemistry (IHC). Collectively, our findings reveal the integrated multidimensional metabolomics approach is a clinical useful method to unravel the blood-tumor metabolic crosstalk, illuminate reprogrammed metabolic networks, and provide reliable circulating biomarkers.

Extra Virgin Olive Oil's Main Components' Antioxidant Activity and in Silico Effect on AKT1.

The study compared the chemical composition of various olive oils from the northern Algerian province of Bejaia. The research focused on the antioxidant activities of the oil's main constituents and their ability to inhibit the AKT1 protein, which is implicated in the development of colorectal cancer. The findings revealed that all of the examined oils fell within the extra virgin olive oil (EVOO) category and exhibited a high oleic acid content, particularly for samples from wild olives. These oils include high amount of ligstroside and oleocanthal, two important phenolic compounds. Wild olive oils stand out from cultivated ones due to their higher bitterness index. In addition, these oils have the highest concentrations of α-tocopherols and the best oxidative stability. Olive oil extracts demonstrated their antioxidant properties by neutralizing DPPH and ABTS radicals and converting ferric ions (Fe3+) to ferrous ions (Fe2+) for FRAP assay. Molecular docking was applied to assess the interaction between the main compounds identified in the analyzed olive oils and the human AKT1 protein, which is involved in the genesis of colorectal cancer. The findings revealed that lutein, oleuropein aglycone, and ligstroside aglycone had the highest binding affinity for the AKT1 protein. The present study could provide the theoretical foundation for further research on the interaction between AKT1 protein and EVOO compounds.

Three-in-One: Molecular Engineering of D-A-π-A Featured Type I and Type II Near-Infrared AIE Photosensitizers for Efficient Photodynamic Cancer Therapy and Bacteria Killing.

Bacterial infections are closely correlated with the genesis and progression of cancer, and the elimination of cancer-related bacteria may improve the efficacy of cancer treatment. However, the combinatorial therapy that utilizes two or more chemodrugs will increase potential adverse effects. Image-guided photodynamic therapy is a highly precise and potential therapy to treat tumor and microbial infections. Herein, four donor-acceptor-π-bridge-acceptor (D-A-π-A) featured near-infrared (NIR) aggregation-induced emission luminogens (AIEgens)(TQTPy, TPQTPy, TQTC, and TPQTC) with type I and type II reaction oxygen species (ROS) generation capabilities are synthesized. Notably, TQTPy shows mitochondria targeted capacity, the best ROS production efficiency, long-term tumor retention capacity, and more importantly, the three-in-one fluorescence imaging guided therapy against both tumor and microbial infections. Both in vitro and in vivo results validate that TQTPy performs well in practical biomedical application in terms of NIR-fluorescence imaging-guided photodynamic cancer diagnosis and treatment. Moreover, the amphiphilic and positively charged TQTPy is able to specific and ultrafast discrimination and elimination of Gram-positive (G+) Staphylococcus aureus from Gram-negative (G-) Escherichia coli and normal cells. This investigation provides an instructive way for the construction of three-in-one treatment for image-guided photodynamic cancer therapy and bacteria elimination.

Construction of prognostic markers for gastric cancer and comprehensive analysis of pyroptosis-related long non-coding RNAs.

China's most frequent malignancy is gastric cancer (GC), which has a very poor survival rate, and the survival rate for patients with advanced GC is dismal. Pyroptosis has been connected to the genesis and development of cancer. The function of pyroptosis-related long non-coding RNAs (PRLs) in GC, on the other hand, remains uncertain. To explore the construction and comprehensive analysis of the prognostic characteristics of long non-coding RNA (lncRNA) related to pyroptosis in GC patients. The TCGA database provided us with 352 stomach adenocarcinoma samples, and we obtained 28 pyroptotic genes from the Reactome database. We examined the correlation between lncRNAs and pyroptosis using the Pearson correlation coefficient. Prognosis-related PRLs were identified through univariate Cox analysis. A predictive signature was constructed using stepwise Cox regression analysis, and its reliability and independence were assessed. To facilitate clinical application, a nomogram was created based on this signature. we analyzed differences in immune cell infiltration, immune function, and checkpoints between the high-risk group (HRG) and low-risk group (LRG). Five hundred and twenty-three PRLs were screened from all lncRNAs (absolute correlation coefficient > 0.4, P < 0.05). Nine PRLs were included in the risk prediction signature that was created through stepwise Cox regression analysis. We determined the risk score for GC patients and employed the median value as the dividing line between HRG and LRG. The ability of the risk signature to predict the overall survival (OS) of GC is demonstrated by the Kaplan-Meier analysis, risk curve, receiver operating characteristic curve, and decision curve analysis curve. The risk signature was shown to be an independent prognostic factor for OS in both univariate and multivariate Cox regression analyses. HRG showed a more efficient local immune response or modulation compared to LRG, as indicated by the predicted signal pathway analysis and examination of immune cell infiltration, function, and checkpoints (P < 0.05). In general, we have created a brand-new prognostic signature using PRLs, which may provide ideas for immunotherapy in patients with GC.

A Comprehensive Review of In vitro Testing and Emerging Strategies Employed in Anticancer Drug Discovery Therapy

Cancer is a broad category of diseases characterized through the unchecked proliferation and dissemination of atypical cells. It is among the primary causes of morbidity and mortality globally. The multistage genesis of cancer, which begins with genetic abnormalities that cause normal cells to become malignant, is what gives cancer its complexity. There are several steps involved in the genesis of cancer, including six key cancer distinguishing features known to influence malignant change has been identified. Anticancer drug development is a laborious process that includes numerous in vitro, in vivo, and clinical trials. In vitro assays provide a foundation for cancer medication development techniques. Numerous in vitro procedures and tests have been developed to analyze every defining aspect of cancer; the choice of a specific in vitro technique or assay is largely based on the research question(s) under investigation. Currently, oncology researchers are attempting to create cancer nanomedicines that are both safe and effective. While nanoparticles have opened up new therapeutic and diagnostic avenues, stem cell treatment has demonstrated potential usefulness in renewing and repairing defective or damaged tissues by tackling primary and metastatic cancer sites. With minimal harm to healthy cells, targeted therapy has the potential to stop the development and propagation of specific cancer cells. In place of open surgery, ablation therapy has become a popular minimally invasive method for destroying or freezing tumors. Naturally occurring antioxidants have demonstrated the ability to find free radicals and counteract their harmful effects, potentially treating or preventing cancer. A number of novel technologies have previously received authorization, and some are presently the subject of clinical trials. This review article's objective is to provide an extensive overview of the state of our knowledge on cancer, covering its causes, kinds, diagnosis, therapy, in vitro assays to screen cancer and most recent scientific developments.

Exploring SALL4 as a significant prognostic marker in breast cancer and its association with progression pathways involved in cancer genesis

Breast carcinoma is the leading factor in women's cancer-related fatalities. Due to its numerous inherent molecular subtypes, breast cancer is an extremely diverse illness. The human epidermal growth factor receptor 2 (HER2) positive subtypes stands out among these subtypes as being especially prone to cancer development and illness recurrence. The regulation of embryonic stem cells' pluripotency and self-renewal is carried out by the SALL4 (Spalt-like transcription factor 4) family member. Numerous molecular pathways operating at the transcriptional, post-transcriptional, and epigenomic levels regulate the expression of SALL4. Many transcription factors control the expression of SALL4, with STAT3 being the primary regulator in hepatocellular carcinoma (HCC) and breast carcinoma. Moreover, this oncogene has been connected to a number of cellular functions, including invasion, apoptosis, proliferation, and resistance to therapy. Reduced patient survival rates and a worse prognosis have been linked to higher levels of SALL4. In order to target the undruggable SALL4 that is overexpressed in breast carcinoma, we investigated the prognostic levels of SALL4 in breast carcinoma and its interaction with various related proteins. Using TIMER 2.0 analysis, the expression pattern of SALL4 was investigated across all TCGA datasets. The research revealed that SALL4 expression was elevated in various cancers. The UALCAN findings demonstrated that SALL4 was overexpressed in all tumor samples including breast cancer especially TNBC (Triple negative breast cancer). The web-based ENRICHR program was used for gene ontology analysis that revealed SALL4 was actively involved in the development of the nervous system, positive regulation of stem cell proliferation, regulation of stem cell proliferation, regulation of the activin receptor signaling pathway, regulation of transcription using DNA templates, miRNA metabolic processes, and regulation of transcription by RNA Polymerase I. Using the STRING database, we analyzed the interaction and involvement of SALL4 with other abruptly activated proteins and used Cytoscape 3.8.0 for visualization. Additionally, using bc-GenExMiner, we studied the impact of SALL4 on pathways abruptly activated in different breast cancer subtypes that revealed SALL4 was highly correlated with WNT2B, NOTCH4, AKT3, and PIK3CA. Furthermore, to target SALL4, we evaluated and analyzed the impact of CLP and its analogues, revealing promising outcomes.

Small molecule inhibitors of the VEGF and tyrosine kinase for the treatment of cervical cancer.

Cervical cancer accounts for most deaths due to cancer in women, majorly in developing nations. The culprit behind this disease is the human papillomavirus(HPV) which accounts for more than 90% of cervical cancer cases. The viral strains produce proteins that favor the knocking down of the apoptosis process and continuous growth of cells in the cervix leading to tumor growth. Proangiogenic growth factors, such as fibroblast growth factor (FGF), vascular endothelial growth factor (VEGF), angiopoietins, and other endothelial growth factors (EGF), are secreted by tumor cells and the surrounding microenvironment, which further advances the development of cancer. The extracellular domain of receptor tyrosine kinases is employed by ligands (like VEGF and EGF) to engage and activate them by inducing receptor dimerization, which facilitates the cascade impact of these factors. The tyrosine kinase domains of each receptor autophosphorylate each other, activating the receptor and initiating signaling cascades that promote angiogenesis, migration, proliferation, and survival of endothelial cells. Cancer cells benefit from its modified signaling pathways, which cause oncogenic activation. Upon early cervical cancer detection, the second-line therapy strategy involves blocking the signaling pathways with VEGF and small molecule tyrosine kinase inhibitors (TKIs). This review paper highlights the genesis of cervical cancer and combating it using VEGF and tyrosine kinase inhibitors by delving into the details of the currently available inhibitors. Further, we have discussed the inhibitor molecules that are currently in various phases of clinical trials. This paper will surely enhance the understanding of cervical cancer and its treatment approaches and what further interventions can be done to alleviate the disease currently serving as a major health burden in the developing world.

Elucidating hematological profile and electrolyte balance in oral cancer patients.

Oral cancer is a serious health issue in both the developing and developed worlds, and it is one of the most common forms of cancer of the head and neck. In accordance with the 2017 World Health Organization classification, oral cancer can affect any part of the mouth, including the buccal mucosa, the front two-thirds of the tongue, the lip, the palate, the vestibule, the alveolus, the floor of the mouth, and the gingivae. Hematology and electrolyte balance have been proposed as tumor indicators and paths into cancer's genesis. Examining the patient's blood count and electrolyte levels in order to better understand their oral cancer. Electrolyte abnormalities are common in cancer patients and may be caused by the disease itself or by treatment. Hyponatremia is the most frequent electrolyte problem in cancer patients, and it is typically caused by the syndrome of improper ADH secretion. Although electrolyte problems are associated with a worse prognosis for cancer patients, timely and effective therapy has the potential to enhance both short- and long-term results and quality of life. Hematological tests on patients with oral cancer, including differential cell count, white blood cell count, and hemoglobin level. Compared to healthy controls, oral cancer patients show statistically significant differences in a number of biochemical parameters, including electrolytes (sodium, P<0.05; potassium, P=0.89; chloride, P<0.05); differential count (neutrophils, P<0.05; basophils, P<0.05). A significant risk factor for cancer patients is an electrolyte imbalance, which has been linked to inappropriate anti-diabetic hormone release. Clinicians will find these shifts in electrolytic level helpful in diagnosing and tracking oral cancer. Potentially malignant oral disorders and Oral squamous cell carcinoma may be better predicted using a combination of TLC, neutrophil, and lymphocyte counts, as shown in this study.
