Peptide Vaccines as Therapeutic and Prophylactic Agents for Female-Specific Cancers: The Current Landscape.

Breast and gynecologic cancers are significant global threats to women's health and those living with the disease require lifelong physical, financial, and social support from their families, healthcare providers, and society as a whole. Cancer vaccines offer a promising means of inducing long-lasting immune response against the disease. Among various types of cancer vaccines available, peptide vaccines offer an effective strategy to elicit specific anti-tumor immune responses. Peptide vaccines have been developed based on tumor associated antigens (TAAs) and tumor specific neoantigens which can also be of viral origin. Molecular alterations in HER2 and non-HER2 genes are established to be involved in the pathogenesis of female-specific cancers and hence were exploited for the development of peptide vaccines against these diseases, most of which are in the latter stages of clinical trials. However, prophylactic vaccines for viral induced cancers, especially those against Human Papillomavirus (HPV) infection are well established. This review discusses therapeutic and prophylactic approaches for various types of female-specific cancers such as breast cancer and gynecologic cancers with special emphasis on peptide vaccines. We also present a pipeline for the design and evaluation of a multiepitope peptide vaccine that can be active against female-specific cancers.

Adoptive cell therapy for cancer treatment.

Adoptive cell therapy (ACT) is a rapidly growing anti-cancer strategy that has shown promise in treating various cancer types. The concept of ACT involves activating patients' own immune cells ex vivo and then transferring them back to the patients to recognize and eliminate cancer cells. Currently, the commonly used ACT includes tumor-infiltrating lymphocytes (TILs), genetically engineered immune cells, and dendritic cells (DCs) vaccines. With the advancement of cell culture and genetic engineering techniques, ACT has been used in clinics to treat malignant hematological diseases and many new ACT-based regimens are in different stages of clinical trials. Here, representative ACT approaches are introduced and the opportunities and challenges for clinical translation of ACT are discussed.

In the quest for histone deacetylase inhibitors: current trends in the application of multilayered computational methods.

Histone deacetylase (HDAC) inhibitors have gained attention over the past three decades because of their potential in the treatment of different diseases including various forms of cancers, neurodegenerative disorders, autoimmune, inflammatory diseases, and other metabolic disorders. To date, 5 HDAC inhibitor drugs are marketed for the treatment of hematological malignancies and several drug-candidate HDAC inhibitors are at different stages of clinical trials. However, due to the toxic side effects of these drugs resulting from the lack of target selectivity, active studies are ongoing to design and develop either class-selective or isoform-selective inhibitors. Computational methods have aided the discovery of HDAC inhibitors with the desired potency and/or selectivity. These methods include ligand-based approaches such as scaffold hopping, pharmacophore modeling, three-dimensional quantitative structure-activity relationships (3D-QSAR); and structure-based virtual screening (molecular docking). The current trends involve the application of the combination of these methods and incorporating molecular dynamics simulations coupled with Poisson-Boltzmann/molecular mechanics generalized Born surface area (MM-PBSA/MM-GBSA) to improve the prediction of ligand binding affinity.This review aimed at understanding the current trends in applying these multilayered strategies and their contribution to the design/identification of HDAC inhibitors.

Research advances in drug therapy of endometriosis.

Endometriosis is one of the most common benign gynecological disorders in reproductive-aged women. The major symptoms are chronic pelvic pain and infertility. Despite its profound impact on women's health and quality of life, its pathogenesis has not been fully elucidated, it cannot be cured and the long-term use of drugs yields severe side effects and hinders fertility. This review aims to present the advances in pathogenesis and the newly reported lead compounds and drugs managing endometriosis. This paper investigated Genetic changes, estrogen-dependent inflammation induction, progesterone resistance, imbalance in proliferation and apoptosis, angiogenesis, lymphangiogenesis and neurogenesis, and tissue remodeling in its pathogenesis; and explored the pharmacological mechanisms, constitutive relationships, and application prospects of each compound in the text. To date, Resveratrol, Bay1316957, and bardoxifene were effective against lesions and pain in controlled animal studies. In clinical trials, Quinagolide showed no statistical difference with the placebo group; the results of phase II clinical trial of the IL-33 antibody have not been announced yet; clinical trial stage III of vilaprisan was suspended due to drug toxicity. Elagolix was approved for the treatment of endometriosis-related pain, but clinical studies of Elagolix for the pretreatment of patients with endometriosis to before In vitro fertilization treatment have not been fulfilled. The results of a clinical study of Linzagolix in patients with moderate to severe endometriosis-related pain have not been disclosed yet. Letrozole improved the fertility of patients with mild endometriosis. For endometriosis patients with infertility, oral GnRH antagonists and aromatase inhibitors are promising drugs, especially Elagolix and Letrozole.

Micro-Magnetofluidic System for Rare Cell Analysis: From Principle to Translation

Rare cells play essential roles in the initiation and progression of diseases and therefore their analysis is of great interest. The micro-magnetofluidic system is one of the emerging platforms that have been proposed for the rapid, sensitive, and cost-effective analysis of rare cells. Given its unprecedented throughput, micro-magnetofluidic systems have attracted substantial research interest in the last decade—multiple designs have been proposed, validated, and even advanced to the stage of clinical trials. This mini review aims to provide a timely summary of the relevant progress in the field thus far. We reviewed the concepts and realizations of micro-magnetofluidic devices based on the interaction between nanoparticles and on-chip micro-magnets. Their real-world applications in rare cell analysis were also highlighted and explained. In addition, we discussed the major challenges in the development and translation of micro-magnetofluidic into the clinic, including multi-marker capability and large-scale manufacturability.

Targeting pre-mRNA splicing in cancers: roles, inhibitors, and therapeutic opportunities.

Accumulating evidence has indicated that pre-mRNA splicing plays critical roles in a variety of physiological processes, including development of multiple diseases. In particular, alternative splicing is profoundly involved in cancer progression through abnormal expression or mutation of splicing factors. Small-molecule splicing modulators have recently attracted considerable attention as a novel class of cancer therapeutics, and several splicing modulators are currently being developed for the treatment of patients with various cancers and are in the clinical trial stage. Novel molecular mechanisms modulating alternative splicing have proven to be effective for treating cancer cells resistant to conventional anticancer drugs. Furthermore, molecular mechanism-based combination strategies and patient stratification strategies for cancer treatment targeting pre-mRNA splicing must be considered for cancer therapy in the future. This review summarizes recent progress in the relationship between druggable splicing-related molecules and cancer, highlights small-molecule splicing modulators, and discusses future perspectives of splicing modulation for personalized and combination therapies in cancer treatment.

Liposomal delivery system/adjuvant for tuberculosis vaccine.

As reported by the World Health Organization, about 10 million individuals were infected with tuberculosis (TB) worldwide. Moreover, approximately 1.5 million people died of TB, of which 214,000 were infected with HIV simultaneously. Due to the high infection rate, the need for effective TB vaccination is highly felt. Until now, various methodologies have been proposed for the development of a protein subunit vaccine for TB. These vaccines have shown higher protection than other vaccines, particularly the Bacillus culture vaccine. The delivery system and safety regulator are common characteristics of effective adjuvants in TB vaccines and the clinical trial stage. The present study investigates the current state of TB adjuvant research focusing on the liposomal adjuvant system. Based on our findings, the liposomal system is a safe and efficient adjuvant from nanosize to microsize for vaccinations against TB, other intracellular infections, and malignancies. Clinical studies can provide valuable feedback for developing novel TB adjuvants, which ultimately enhance the impact of adjuvants on next-generation TB vaccines.

Effects of ruxolitinib and magrolimab on calreticulin in myelofibrosis CD34+ cells in vitro: Proof of concept for combination therapy.

7064 Background: In solid tumours, calreticulin (CALR) overexpression produces a pro-phagocytic signal and is counteracted by concomitant expression of anti- phagocytic CD47, reflecting an apoptosis vs survival mechanism. We have previously found that CD47, not CALR, is overexpressed on the membrane of patients with MPN. Anti-CD47 Magrolimab, is currently being evaluated in clinical trials in AML, MDS but have yet to be tested, either in monotherapy or in combination in MF. Methods: Mononuclear cells were collected by Ficoll separation from bone marrow of 6 MF patients and from 2 controls. CD34+ cells and monocytes were purified using Dynabeads kits from Thermofisher. Cells expression of CALR and CD47 was measured by flow cytometry, before and after incubation with ruxolitinib (Jak inhibitor) alone and in combination with magrolimab. Cells survival was calculated after combining CD34 with monocytes. Informed Consent was obtained for all samples collected. Results: CD47 membrane expression was 57% in untreated MF cells compared to 12% in the control samples and CALR membrane expression was 51.8% in untreated MF cell compared to 12.5% in the control samples. After incubation with ruxolitinib, MF CD34+ cell survival decreased to 98.2%. Following Incubation with magrolimab alone, MF CD34+ cells show no changes in survival (100% alive). The combination of ruxolitinib and magrolimab reduced slightly the MF CD34+ cell survival to 92%. A substantial membrane overexpression of CALR was observed in MF CD34+ cells when incubated with Ruxo and Magrolimab, 74.1%, vs Ruxo alone 52.6%, Magrolimab alone 53.4% and in untreated (51.8%). Interestingly, in the healthy controls, the exposure to combination therapy did not cause the same degree of CALR overexpression (20.7% vs 12.5%), indicating a much stronger pro-phagocytic effect following magrolimab/ruxolitinib combo in MF cancer cells. Conclusions: In vitro, treatment with ruxolitinib or ruxolitinib plus magrolimab, slightly reduce the overall cell survival rate in CD34+ MF samples, comparing with no significant changes in single agent magrolimab. However, the combination of Ruxolitinib and Magrolimab significantly increases CALR membrane expression comparing with Ruxo or Magrolimab alone, signalling a much stronger pro-phagocytic message in MF cells comparing with controls. The induced CALR over-expression, could stimulate a stronger immune response in vivo, where the presence of macrophages would allow removal of CALR rich cells and potentiate the cytoreductive activity towards MF clone. These data support the rational of combining Ruxolitinib with Magrolimab in the next clinical trial stage in myelofibrosis.

РАДИАЦИОННО-ИНДУЦИРОВАННАЯ БОЛЕЗНЬ СЕРДЦА: ПРИЧИНЫ, ПРОЯВЛЕНИЯ, ПРОФИЛАКТИКА

The article discusses the causes of the development of radiation-induced heart disease - one of the significant complications of chest radiation therapy. Treating cancer with this method triggers the mechanism of pathological changes in the heart. There are a number of risk factors contributing to this complication in patients. The most common clinical forms of radiation-induced heart disease are identified, as well as a characteristic of their signs. The timing of the appearance of these signs for each form may be different, in addition, they vary depending on the reason for the use of radiation therapy. The possibilities of diagnosing selected conditions are indicated, which oncologists and doctors of other specialties should actively apply in the tactics of managing patients who have undergone oncological diseases of the mammary glands or chest organs. These diagnostic methods are not different from the main methods of diagnosing cardiac diseases, they are affordable and safe. The article also provides methods for the primary and secondary prevention of radiation-induced heart disease, which begin with the choice of a method of treatment for an oncological patient. Now there are many radiotherapy options that reduce the dose and area of radiation, which can minimize the risks of deterioration in the quality of life and prognosis of the patient. The next important principle is the correction of lifestyle and modifiable cardiovascular risk factors. Also indicated are variants of drugs used in cardiac practice, with the help of which, possibly, in the future, the prevention of radiation-induced heart disease will be carried out, but so far they are at the stage of clinical trials.

Targeting genomic DNAs and oligonucleotide on base specificity: A comparative spectroscopic, computational and in vitro study

Drug discovery in targeted nucleic acid therapeutics encompass several stages and rigorous challenges owing to less specificity of the DNA binders and high failure rate in different stages of clinical trials. In this perspective, we report newly synthesized ethyl 4-(pyrrolo[1,2-a]quinolin-4-yl)benzoate (PQN) with minor groove A-T base pair binding selectivity and encouraging in cell results. This pyrrolo quinolin derivative has shown excellent groove binding ability with three of our inspected genomic DNAs (cpDNA 73 % AT, ctDNA58% AT and mlDNA 28 % AT) with varying A-T and G-C content. Notably in spite of similar binding patterns PQN have strong binding preference with A-T rich groove of genomic cpDNA over the ctDNA and mlDNA. Spectroscopic experiments like steady state absorption and emission results have established the relative binding strengths (Kabs = 6.3 × 105 M−1, 5.6 × 104 M−1, 4.3 × 104 M−1 and Kemiss = 6.1 × 105 M−1, 5.7 × 104 M−1 and 3.5 × 104 M−1 for PQN-cpDNA, PQN-ctDNA and PQN-mlDNA respectively) whereas circular dichroism and thermal melting studies have unveiled the groove binding mechanism. Specific A-T base pair attachment with van der Waals interaction and quantitative hydrogen bonding assessment were characterized by computational modeling. In addition to genomic DNAs, preferential A-T base pair binding in minor groove was also observed with our designed and synthesized deca-nucleotide (primer sequences 5/-GCGAATTCGC-3/ and 3/-CGCTTAAGCG-5/). Cell viability assays (86.13 % in 6.58 μM and 84.01 % in 9.88 μM concentrations) and confocal microscopy revealed low cytotoxicity (IC50 25.86 μM) and efficient perinuclear localization of PQN. We propose PQN with excellent DNA-minor groove binding capacity and intracellular permeation properties, as a lead for further studies encompassing nucleic acid therapeutics.

The anticancer mechanism of Terpenoid-based drug candi-dates: focus on tumor microenvironment.

Cancer is considered to be the most lethal threat to human life globally. Although, versatile strategies have been established in the field of surgery, chemotherapy, radiotherapy and im-munotherapy against cancer, discovery of new therapeutic drugs from natural products still un-derlays anticancer remedy due to their unique functional mechanisms and potential low side ef-fects. Terpenoids are among the most diversified and enormous natural products which have been proved promising in cancer treatment. Some terpenoids have been through multiple stages of clinical trials and some even approved as anticancer agent, but most of these studies empha-sized the direct effects on tumor cells while paying less attention to their systemic effects on tu-mor microenvironment (TME) Therefore, we recruited the patent drugs and investigated drug candidates of terpenoids in this review and summarized their general anti-tumor mechanisms among which the regulation on TME was highlighted. Finally, the prospect on the drug ability of terpenoids and their potential benefits in immunotherapy were discussed to illuminate fur-ther researches on these natural products. Keywords.

Cuproptosis Regulates Microenvironment and Affects Prognosis in Prostate Cancer.

Current immunotherapy for prostate cancer is still in the stage of clinical trials. This delay is thought to be caused by an unclear regulatory mechanism of the immune microenvironment, which makes it impossible to distinguish patients suitable for immunotherapy. Cuprotosis may be related to the heterogeneity of immune microenvironment, which was regarded as a new copper-dependent cell death mode, was proposed, and gain attention. We explored for the first time the relationship between cuprotosis and the immune microenvironment of prostate cancer and constructed cuprotosis score. RNA sequencing data sets for prostate cancer were downloaded from public databases. Consensus clustering was applied to distinguish cuprotosis phenotype based on the expression of cuproptosis-related genes (CRGs) identified as prognostic factors. Genomic phenotypes of CRG clusters were depicted via consensus clustering. Cuprotosis score was established on the basis of differentially expressed genes (DEGs) identified as prognostic factors via principal component analysis. Cuprotosis score = the first principal component of prognostic factors + the second principal component of prognostic factors. The value of cuproptosis score in predicting prognosis and immunotherapy response was evaluated. PDHA1 (HR = 3.86, P < 0.001) and GLS (HR = 1.75, P = 0.018) were risk factors for prognosis of prostate cancer patients, while DBT (HR = 0.66, P = 0.048) was a favorable factor for prognosis of prostate cancer patients. CRG clusters had different prognosis and immune cell infiltration. So as gene clusters. Prostate cancer patients with low cuprotosis score showed better prognosis for biochemical relapse-free survival. Cuprotosis score is accompanied with high immune score and Gleason score. As cuprotosis genes, PDHA1, GLS, and DBT were identified as independent prognostic factors of prostate cancer. Cuprotosis score was established via principal component analysis of PDHA1, GLS, and DBT, which can be used as a predictor of prognosis and immunotherapy response of prostate cancer patients, and can characterize immune cells infiltration in tumors. Cuproptosis was involved in the regulation of immune microenvironment, which may depend on the effect of tricarboxylic acid cycle. Our study provided clues to reveal the relationship between copper death and immune microenvironment, highlighted the clinical significance of cuproptosis, and provided a reference for the development of personalized immunotherapy.

Therapeutic Potential and Application Prospects of Antimicrobial Peptides in the Era of Global Spread of Antibiotic Resistance

In the era of the growing global threat of antibiotic resistance, antimicrobial peptides (AMPs) are considered as new generation drugs for treatment of various infectious diseases. In this review, AMPs are seen as an alternative to traditional antibiotics, many of which have already lost or are gradually reducing their effectiveness against a number of critically important pathogenic microorganisms. Recent outbreaks of secondary infections during the COVID-19 pandemic have increased the interest in AMPs due to an acute shortage of effective agents against bacterial and fungal infections. The review summarized current data on clinical studies of AMPs, assembled a list of developed drugs based on AMPs at various stages of clinical trials, highlighted the urgency of study of new AMPs, and systematized the most relevant clinical data and application of AMPs.

Synthetic Methodologies and SAR of Quinazoline Derivatives as PI3K Inhibitors.

PI3K is an important anticancer target as it controls cellular functions such as growth, transformation, proliferation, motility and differentiation. Plasma cell cancer (multiple myeloma) occurs more than 10% among all haematological malignancies and accounts for 2% of all cancer-related deaths each year, it is mainly regulated by PI3K/AKT signaling cascade. Quinazoline derivatives have been reported as promising PI3K inhibitors. Lapatinib, afatinib, gefitinib, erlotinib, idelalisib and copanlisib are quinazoline-based, FDA-approved PI3K inhibitors, while compounds like NVPBYL719, GDC-0032, AZD8186, AZD-6482, etc. are under different stages of clinical trials. In light of the above-mentioned facts, in the present study, we have reported different synthetic approaches, mechanisms of anticancer action, and structure-activity relationship analysis of reported quinazoline derivatives as PI3K inhibitors to help researchers working in the field in designing better and isoform-selective PI3K inhibitors.

SMA Therapy in Poland: New Hopes and Challenges

Abstract: Spinal muscular atrophy (SMA) is a genetically inherited disease whose symptoms appear in children at a fairly early age. The main cause of the disease is a mutation of the SMN1 gene, which causes the lack of production of SMN This results in the disappearance of motoneurons, which consequently leads to the disappearance of the patient's ability to move and his death. An important element of coping with the disease is its early detection in newborn screening, because the earlier we start the drug, the greater the chance that the patient will maintain motor efficiency. The article describes treatment options for children in Poland, i. e. the use of such drugs as Nusinersen, which increases the amount of SMN protein, gene therapy Onasemnogen aeparvovec, which increases the amount of SMN gene, Ridisplam, which increases the amount of SMN protein, and salbutamol, which helps patients to breathe. The article also provides information about new drug therapies for the treatment of SMA and the stage of clinical trials at which they are currently being developed. It is important to look for new solutions in the treatment of SMA.&#x0D; Objective: To familiarize the readers of the article with the problems of SMA treatment in Poland, as well as to broaden their knowledge of new available drugs for the treatment of this disease.

Triple-Negative Breast Cancer: Basic Biology and Immuno-Oncolytic Viruses.

Triple-negative breast cancer (TNBC) is the most lethal subtype of breast cancer. TNBC diagnoses account for approximately one-fifth of all breast cancer cases globally. The lack of receptors for estrogen, progesterone, and human epidermal growth factor 2 (HER-2, CD340) results in a lack of available molecular-based therapeutics. This increases the difficulty of treatment and leaves more traditional as well as toxic therapies as the only available standards of care in many cases. Recurrence is an additional serious problem, contributing substantially to its higher mortality rate as compared to other breast cancers. Tumor heterogeneity also poses a large obstacle to treatment approaches. No driver of tumor development has been identified for TNBC, and large variations in mutational burden between tumors have been described previously. Here, we describe the biology of six different subtypes of TNBC, based on differential gene expression. Subtype differences can have a large impact on metastatic potential and resistance to treatment. Emerging antibody-based therapeutics, such as immune checkpoint inhibitors, have available targets for small subsets of TNBC patients, leading to partial responses and relatively low overall efficacy. Immuno-oncolytic viruses (OVs) have recently become significant in the pursuit of effective treatments for TNBC. OVs generally share the ability to ignore the heterogeneous nature of TNBC cells and allow infection throughout a treated tumor. Recent genetic engineering has allowed for the enhancement of efficacy against certain tumor types while avoiding the most common side effects in non-cancerous tissues. In this review, TNBC is described in order to address the challenges it presents to potential treatments. The OVs currently described preclinically and in various stages of clinical trials are also summarized, as are their strategies to enhance therapeutic potential.

A proof-of-concept assay for quantitative and optical assessment of drug-induced toxicity in renal organoids

Kidneys are complex organs, and reproducing their function and physiology in a laboratory setting remains difficult. During drug development, potential compounds may exhibit unexpected nephrotoxic effects, which imposes a significant financial burden on pharmaceutical companies. As a result, there is an ongoing need for more accurate model systems. The use of renal organoids to simulate responses to nephrotoxic insults has the potential to bridge the gap between preclinical drug efficacy studies in cell cultures and animal models, and the stages of clinical trials in humans. Here we established an accessible fluorescent whole-mount approach for nuclear and membrane staining to first provide an overview of the organoid histology. Furthermore, we investigated the potential of renal organoids to model responses to drug toxicity. For this purpose, organoids were treated with the chemotherapeutic agent doxorubicin for 48 h. When cell viability was assessed biochemically, the organoids demonstrated a significant, dose-dependent decline in response to the treatment. Confocal microscopy revealed visible tubular disintegration and a loss of cellular boundaries at high drug concentrations. This observation was further reinforced by a dose-dependent decrease of the nuclear area in the analyzed images. In contrast to other approaches, in this study, we provide a straightforward experimental framework for drug toxicity assessment in renal organoids that may be used in early research stages to assist screen for potential adverse effects of compounds.
