Asprosin-induced alterations in female rat puberty and reproductive hormonal profiles

Objective To investigate the comprehensive effects of daily chronic asprosin administration on various pubertal and reproductive parameters in female rats. This study aims to elucidate the role of asprosin in regulating the onset of puberty and its influence on hormonal profiles and ovarian histology. Methods Asprosin was administered intraperitoneally (i.p.) at a dose of 500 ng/kg daily for eight weeks. Hormonal assays and histological analyses were performed to evaluate the effects of asprosin on the onset of puberty and reproductive function. Results Daily chronic administration of asprosin accelerated the onset of the first oestrus. Hormonal assays revealed significant elevations in serum levels of Follicle-Stimulating Hormone (FSH) and Oestradiol (E2), while Inhibin B levels decreased. Histological evaluations demonstrated an increased number of primary and secondary follicles in ovarian tissue, without affecting primordial follicle counts or reproductive organ weights. Conclusions Role of adipokines in regulating puberty and reproductive function has increasingly gained recognition. This study aimed to provide the first comprehensive examination of the effects of daily chronic asprosin administration on pubertal and reproductive parameters in female rats. Utilising hormonal assays and histological analyses, asprosin was administered intraperitoneally (i.p.) at a dose of 500 ng/kg, daily, for eight weeks. Our findings revealed that daily chronic administration of asprosin accelerated the onset of the first oestrus. Hormonal assays showed significant elevations in serum levels of Follicle-Stimulating Hormone (FSH) and Oestradiol (E2), while Inhibin B levels decreased. Histological evaluations demonstrated an increased number of primary and secondary follicles in ovarian tissue, without affecting primordial follicle counts or reproductive organ weights. These results provide new insights into asprosin’s role in advancing the age of first oestrus and modulating hormonal profiles, thereby offering potential benefits to the female reproductive system.

Single-nucleus atlas of the Artemia female reproductive system suggests germline repression of the Z chromosome.

Our understanding of the molecular pathways that regulate oogenesis and define cellular identity in the Arthropod female reproductive system and the extent of their conservation is currently very limited. This is due to the focus on model systems, including Drosophila and Daphnia, which do not reflect the observed diversity of morphologies, reproductive modes, and sex chromosome systems. We use single-nucleus RNA and ATAC sequencing to produce a comprehensive single nucleus atlas of the adult Artemia franciscana female reproductive system. We map our data to the Fly Cell Atlas single-nucleus dataset of the Drosophila melanogaster ovary, shedding light on the conserved regulatory programs between the two distantly related Arthropod species. We identify the major cell types known to be present in the Artemia ovary, including germ cells, follicle cells, and ovarian muscle cells. Additionally, we use the germ cells to explore gene regulation and expression of the Z chromosome during meiosis, highlighting its unique regulatory dynamics and allowing us to explore the presence of meiotic sex chromosome silencing in this group.

Immunity to Sexually Transmitted Bacterial Infections of the Female Genital Tract: Toward Effective Vaccines.

Sexually transmitted infections (STIs) caused by bacterial pathogens Chlamydia trachomatis, Neisseria gonorrhoeae, and Treponema pallidum present significant public health challenges. These infections profoundly impact reproductive health, leading to pelvic inflammatory disease, infertility, and increased susceptibility to other infections. Prevention measures, including antibiotic treatments, are limited by the often-asymptomatic nature of these infections, the need for repetitive and continual screening of sexually active persons, antibiotic resistance for gonorrhea, and shortages of penicillin for syphilis. While vaccines exist for viral STIs like human papillomavirus (HPV) and hepatitis B virus (HBV), there are no vaccines available for bacterial STIs. This review examines the immune responses in the female genital tract to these bacterial pathogens and the implications for developing effective vaccines against bacterial STIs.

Molecular genetics and research progress of uterine leiomyosarcoma.

Uterine leiomyosarcoma (uLMS) is a type of malignant soft-tissue tumor, which is developed from myometrium in the female reproductive system. This disease is difficult to be distinguished from benign uterine leiomyoma in the early stages, but it progresses aggressively and relentlessly. Hence, uLMS has a dismal prognosis and high rates of both misdiagnosis and missed diagnosis. Unfortunately, current studies of uLMS pathogenesis and disease biology are inadequate. uLMS disease models are also very limited, hindering the development of effective therapeutics. In this review, we focus on the pathological molecular biology of uLMS, and systematically review the molecular genetic features, epigenetic variants, experimental models, and clinical research progress of uLMS. We further discuss the development direction and potential needs of uLMS in the fields of tumor evolution, tumor microenvironment, and tumor therapy, with the aim of providing a better understanding of the pathobiological mechanism of uLMS and providing a reference for the development of potential diagnostic and therapeutic strategies.

Surface-Conjugated Galactose on Electrospun Polycaprolactone Nanofibers: An Innovative Scaffold for Uterine Tissue Engineering.

The uterus, a vital organ in the female reproductive system, nurtures and supports developing embryos until maturity. This study focuses on addressing uterine related problems by creating a nanofibrous scaffold to regenerate uterine myometrial tissue, closely resembling the native extracellular matrix (ECM) for enhanced efficacy. To achieve this, we utilized polycaprolactone (PCL) as a biomaterial and employed an electrospinning technique to generate PCL nanofibers in both random and aligned orientations. Due to the inherent hydrophobic nature of PCL nanofibers, a two-step wet chemistry surface modification technique is used, involving the conjugation of galactose onto them. Galactose, a lectin-binding sugar, was chosen to enhance the scaffold's hydrophilicity, thereby improving cell adhesion and fostering l-selectin-based interactions between the scaffold and uterine cells. These interactions, in turn, activated uterine fibroblasts, leading to ECM remodeling. The optimized electrospinning process successfully generated random and aligned nanofibers. Subsequent surface modification was carried out, and the modified scaffold was subjected to various physicochemical characterization, such as the ninhydrin assay, enzyme-linked lectin assay techniques that revealed successful galactose conjugation, and mechanical characterization to assess any changes in material bulk properties resulting from the modification. The tensile strength of random galactose-modified PCL fibers reached 0.041 ± 0.01 MPa, outperforming random unmodified PCL fibers (0.026 ± 0.01 MPa), aligned unmodified PCL fibers (0.011 ± 0.001 MPa), and aligned modified PCL fibers (0.016 ± 0.002 MPa). Cytocompatibility studies with human uterine fibroblast cells showed enhanced viability and proliferation on the modified scaffolds. Initial pilot studies were attempted in the current study involving subcutaneous implantation in the dorsal area of Wistar rats to assess biocompatibility and tissue response before proceeding to intrauterine implantation indicated that the modification did not induce adverse inflammation in vivo. In conclusion, our study introduces a surface-modified PCL nanofibrous material for myometrial tissue engineering, offering promise in addressing myometrial damage and advancing uterine health and reproductive well-being.

Cancer Incidence in a Population Living Near Radioactive Waste Storage of Uranium Mining in Stepnogorsk Area, Northern Kazakhstan.

This study evaluates the impact of radioactive uranium waste storage facilities on cancer occurrence in nearby areas. Current research evaluates the effect of radioactive uranium waste storage facilities on cancer epidemiology in nearby areas. The critical area had Aqsu, Kvartsitka, Zavodskoy and Stepnogorsk cities, which are located at a less than 5 km distance to the south of the Hydrometallurgical Plant tailings dump while the control group had Akkol region in 90 km from the source. The majority of population had lived in this territory more than the 30 years. Data were obtained from the Electronic Register of Cancer Patients of the Republic of Kazakhstan from 2001-2015, and 2,271 incident cases of cancer were registered. The most frequent malignancies were observed in the digestive organs (646 cases, 28%) and respiratory and intrathoracic organs (376 cases, 17%). The proportion of digestive organ cancers was higher in the critical group (560 cases out of 1913, 29%) than in the control group (86 cases out of 358, 24%). Additionally, respiratory organ cancers were more common in men, but the cancer incidence rate ratio was higher in the critical area. Notably, the study found that the cancer incidence rate ratios decreased over time, specifically for digestive, respiratory and female genital organs and breast cancer. In conclusion, while our study highlights significant differences in cancer incidence rates and frequencies between the critical and control groups, further analytical research, incorporating age-adjustment, is needed to provide a more conclusive evaluation of the potential impact of residence in proximity to the uranium mining waste storage on cancer occurrence in the study area.

Chronic inflammation of the male genital tract impairs female genital tract immunomodulation and decrease fertility potential

Uterine fibroids: current research on novel drug targets and innovative therapeutic strategies.

Uterine fibroids, the most common nonmalignant tumors affecting the female genital tract, are a significant medical challenge. This article focuses on the most recent studies that attempted to identify novel non-hormonal therapeutic targets and strategies in UF therapy. This review covers the analysis of the pharmacological and biological mechanisms of the action of natural substances and the role of the microbiome in reference to UFs. This study aimed to determine the potential role of these compounds in UF prevention and therapy. While there are numerous approaches for treating UFs, available drug therapies for disease control have not been optimized yet. This review highlights the biological potential of vitamin D, EGCG and other natural compounds, as well as the microbiome, as promising alternatives in UF management and prevention. Although these substances have been quite well analyzed in this area, we still recommend conducting further studies, particularly randomized ones, in the field of therapy with these compounds or probiotics. Alternatively, as the quality of data continues to improve, we propose the consideration of their integration into clinical practice, in alignment with the patient's preferences and consent.

Implications of the Hippo Pathway Dysregulation in Uterine Leiomyosarcoma.

Uterine leiomyosarcomas (uLMS) are the most common mesenchymal tumors of the female genital tract. uLMS genetics encompass complex karyotypes with no specific molecular alterations. The Hippo pathway has been implicated in the pathogenesis of epithelioid hemangio-endotheliomas and endometrial sarcomas. Hippo pathway effectors are YAP1 and TAZ co-transcriptional factors. We studied Hippo pathway in a series of 32 uLMS patients and its association with clinicopathological parameters. Immunohistochemical analysis of YAP1 and TAZ proteins accompanied with fluorescent in situ hybridization study of YAP1 gene was performed in patient samples. Age, sex, tumor size, stage at the time of diagnosis and treatment have been analyzed. Overall survival (OS) was calculated from the time of diagnosis until death, loss of follow up or data cut-off. Hippo signaling was found to be dysregulated in 20 (62.5%) patients with uLMS. Regarding OS we detected a trend of Hippo deregulation, designating it as a positive prognostic factor. The Hippo pathway is implicated in uLMS oncogenesis, since nuclear expression of YAP1 was detected in 17 (53.1%) of the 32 patients with immunohistochemistry and YAP1 amplification was found in 8 (25%) patients.

Changes in surfactant protein A and D in ovine ovaries related to follicle development.

Surfactant protein A (SP-A) and Surfactant protein D (SP-D) glycoproteins play a crucial role in maintaining lung homeostasis and lung host defense. Interestingly, these proteins are also expressed in extra-pulmonary tissues, including the female genital tract. The ovarian tissue, where SP-A and SP-D expression increases with follicular development, may serve as the primary site of defense for this tissue. However, their functions in these tissues are not well understood and are currently an active area of research. Therefore, the objective of this study is to investigate the expression of SP-A and SP-D in the ovine ovary throughout the ovarian cycle using immunohistochemistry by semiquantitative intensity classification and Western blotting techniques. These findings revealed the presence of SP-A and SP-D in various compartments of the ovary, such as the follicular epithelium, granulosa cells, cumulus cells, theca cells, oocyte I, follicular fluid, and luteal cells of Graafian follicles, excluding the corpus albicans. SP-A and SP-D likely act as a first line of defense against potential pathogens that infiltrate the ovaries. Further investigation of the differential expression of SP-A and SP-D proteins in ovarian follicles will provide a basis for understanding their interactions with key proteins involved in oogenesis.

Redox Balance and Inflammatory Response in Follicular Fluids of Women Recovered by SARS-CoV-2 Infection or Anti-COVID-19 Vaccinated: A Combined Metabolomics and Biochemical Study.

To date, not many studies have presented evidence of SARS-CoV-2 infecting the female reproductive system. Furthermore, so far, no effect of the administration of anti-COVID 19 vaccines has been reported to affect the quality of oocytes retrieved from women who resorted to assisted reproduction technology (ART). The FF metabolic profiles of women who had been infected by SARS-CoV-2 before IVF treatments or after COVID-19 vaccination were examined by 1H NMR. Immunochemical characterization of proteins and cytokines involved in the redox and inflammatory pathways was performed. The increased expression of SOD2 and NQO1, the lack of alteration of IL-6 and CXCL10 levels, as well as the increased expression of CD39, suggested that, both sharing similar molecular mechanisms or proceeding along different routes, the redox balance is controlled in the FF of both vaccinated and recovered women compared to controls. The lower amount of metabolites known to have proinflammatory activity, i.e., TMAO and lipids, further supported the biochemical results, suggesting that the FF microenvironment is controlled so as to guarantee oocyte quality and does not compromise the outcome of ART. In terms of the number of blastocysts obtained after ICSI and the pregnancy rate, the results are also comforting.

Correlation of PD-L1 expression with different clinico-pathological and immunohistochemical features of ovarian surface epithelial tumors.

Primary carcinoma of the ovary (OCs) are responsible for a significant number of deaths related to cancer, and have the highest rate of death related to cancers of the female reproductive organs. Programmed cell death 1 (PD1) protein, acts as an immune checkpoint, and has an important role in the down-regulation of the immune system by preventing the activation of T-cells, which will weaken the autoimmunity and increases self-tolerance. This study aimed at the evaluation of the immunohistochemical (IHC) expression of PD-L1 in various primary surface ovarian epithelial tumours and to test its correlation with different clinicopathological parameters together with the expression of a panel of P53, ER and PR. A set of 102 cases of primary ovarian surface epithelial neoplasms (benign, borderline and malignant) were collected to construct Tissue Microarray (TMA) using 3 tissue cores from each case. IHC for PD-L1, p53, PR and ER was performed. The expression of PD-L1 was evaluated in relation to some clinicopathological parameters and to the expression patterns of other markers. Expression of PD-L1 was detected in about 51% (n = 36) of malignant tumours. The malignant group significantly showed PD-L1 positivity compared to borderline and benign groups. The malignant tumours significantly showed PD-L1 and total p53 positivity in comparison to borderline group. Also, malignant tumours significantly showed higher combined positivity of PD-L1 and either PR or ER compared to borderline and benign lesions. No significant correlation was appreciated between PD-L1 expression and with any of the studied clinicopathological parameters. This study showed a significant PD-L1 expression in malignant primary surface epithelial tumours. Construction of a panel of IHC markers, including PD-L1, could have a potential value to define patients those would benefit from the addition of immunotherapy to the treatment plan.

Identification of a novel gene, Bryophyte Co-retained Gene 1, that has a positive role in desiccation tolerance in the moss Physcomitrium patens.

The moss Physcomitrium patens is a model system for the evolutionary study of land plants, and as such, it may contain as yet unannotated genes with functions related to the adaptation to water deficiency that was required during the water-to-land transition. In this study, we identified a novel gene, Bryophyte Co-retained Gene 1 (BCG1), in P. patens that is responsive to dehydration and rehydration. Under de- and rehydration treatments, BCG1 was significantly co-expressed with DHNA, which encodes a dehydrin (DHN). Examination of previous microarray data revealed that BCG1 is highly expressed in spores, archegonia (female reproductive organ), and mature sporophytes. In addition, the bcg1 mutant showed reduced dehydration tolerance, and this was accompanied by a relatively low level of chlorophyll content during recovery. Comprehensive transcriptomics uncovered a detailed set of regulatory processes that were affected by the disruption to BCG1. Experimental evidence showed that BCG1 might function in antioxidant activity, the abscisic acid pathway, and in intracellular Ca2+ homeostasis to resist desiccation. Overall, our results provide insights into the role of a bryophyte co-retained gene in desiccation tolerance.

NAP1L1 Promotes Endometrial Cancer Progression via EP300-Mediated DDX5 Promoter Acetylation.

Endometrial cancer (EC) is one of the predominant tumors of the female reproductive system. In this current study, we investigated the functions and related mechanisms of NAP1L1/DDX5 in EC. This retrospective study analyzed the medical records of EC patients, collected tissue samples for NAP1L1 and DDX5 staining, and conducted survival analysis using the Kaplan-Meier method. To evaluate the impact of NAP1L1 and/or DDX5 on cellular processes in EC cells, several techniques were employed. These included CCK-8 assay, wound healing assay, Transwell assay, as well as overexpression or knockdown of target gene expression. Additionally, ChIP, dual luciferase reporter gene, Co-IP assay were utilized to confirm the interaction between NAP1L1, EP300 and DDX5. Furthermore, qRT-PCR, western blot and Co-IP assay were performed to analyze the modulation of NAP1L1/DDX5 in Wnt/β-catenin. NAP1L1 and DDX5 expression were upregulated in EC tissues, and correlated with poor prognosis. NAP1L1/DDX5 promoted EC cell proliferation, migration and invasion. NAP1L1 promotes acetylation and transcription by recruiting EP300 to the DDX5 promoter. DDX5 could activate Wnt/β-catenin signal by binding to β-catenin. In animal models, knockdown of NAP1L1 inhibits EC tumor growth and lung metastasis. To sum up, our study demonstrated that NAP1L1 promoted the malignant phenotypes of EC cells via recruiting EP300 to promote DDX5 acetylation, thus activating the Wnt/β-catenin signaling pathway. Implications: Our research findings indicate that targeting the NAP1L1/EP300/DX5 axis might be a new potential treatment option for endometrial cancer.

Based on the results of this study, it is recommended that women of childbearing age can pay attention to reproductive health by conducting IVA examinations as a prevention of cervical cancer

Distribution and morphologic characterization of telocytes in rat ovary and uterus: insights from ultrastructural and immunohistochemical analysis

Telocytes (TCs) are characterized by a small oval-shaped cell body with long prolongations that are called telopods (Tps). PDGFR-β and c-kit markers may assist for the immunohistochemical identification of TCs; however, by these means they cannot be identified with absolute specificity. Transmission electron microscopy (TEM) is considered as a gold standard method for TCs observation. Studies on TCs in the female reproductive system are limited, and there is a lack of awareness regarding TCs in rat ovaries. We aimed to demonstrate the existence and morphology of TCs in rat ovaries, alongside previously studied TCs in rat uteri. Thus, ovaries and uteri from young adult Sprague–Dawley female rats (n = 8) with regular estrous cycles were collected. Then, left ovaries and uteri were proccessed for TEM analysis, while the right ones were used for immunohistochemistry. As a result, TCs were seen throughout the rat’s ovarian stroma with their characteristic cell bodies, Tps, podomes (Pds) and podomers (Pdms). Tps were situated within the thecal layer of the follicles, surrounding the corpus luteum and blood vessels. Ovarian TCs were recognized to have relationship with other TCs/stromal cells. Subsequently, TCs were seen in stroma of endometrium with surrounding blood vessels and uterine glands, myometrium and perimetrium in rat uteri. There was also no statistical significance between the number of c-kit+ and PDGFR-β+ telocyte-like cells in both rat ovarian (p = 0.137) and endometrial stroma (p = 0.450). Further investigation of the roles and functions of TCs in the female reproductive system is needed.

Correlation of serum anti-mullerian hormone and age-related health problems with ovarian function

The objectives of this paper were to analyse the correlation between serum Anti-Mullerian Hormone (AMH) and age-related health issues affecting ovarian function and explore the current opportunities for this novel technique. This article mainly focuses on reviewing the biological processes involved in the female reproductive system and the clinical basis of the development of technologies for female fertility. The Serum AntiMullerian Hormone (AMH) test is a valuable tool for the assessment of ovarian function. The AMH level of each individual sample is catalysed using a Roche Elecsys AMH analyzer and a chemiluminescence immunoassay (ECLA), which measures the light emission of the serum complex at 450 nm. The results demonstrated a strong association between serum AMH levels and age, establishing its reliability in the prediction of the ovarian reserve as well as reproductive lifespan. However, age is not the sole determinant for fertility. Genetic factors, oocyte quality, uterine thickness and other environmental factors showed a potential linkage with ovarian syndromes, which indicates poor ovarian function. Market expansion, raising awareness of reproductive health, policy support, and technological advancements provide multiple channels for the promotion of AMH test technology. These findings can be used for business planning or studying age-related changes on the AMH test.

Identification of Glyoxalase A in Group B Streptococcus and its contribution to methylglyoxal tolerance and virulence.

Group B Streptococcus (GBS) is a Gram-positive pathobiont that commonly colonizes the gastrointestinal and lower female genital tracts but can cause sepsis and pneumonia in newborns and is a leading cause of neonatal meningitis. Despite the resulting disease severity, the pathogenesis of GBS is not completely understood, especially during the early phases of infection. To investigate GBS factors necessary for blood stream survival, we performed a transposon (Tn) mutant screen in our bacteremia infection model using a GBS mariner transposon mutant library previously developed by our group. We identified significantly underrepresented mutations in 628 genes that contribute to survival in the blood, including those encoding known virulence factors such as capsule, the β-hemolysin, and inorganic metal ion transport systems. Most of the underrepresented genes have not been previously characterized or studied in GBS, including gloA and gloB, which are homologs for genes involved in methylglyoxal (MG) detoxification. MG is a byproduct of glycolysis and a highly reactive toxic aldehyde that is elevated in immune cells during infection. Here, we observed MG sensitivity across multiple GBS isolates and confirm that gloA contributes to MG tolerance and invasive GBS infection. We show specifically that gloA contributes to GBS survival in the presence of neutrophils and depleting neutrophils in mice abrogates the decreased survival and infection of the gloA mutant. The requirement of the glyoxalase pathway during GBS infection suggests that MG detoxification is important for bacterial survival during host-pathogen interactions.

Clinicopathological features and prognostic analysis of synchronous mucinous metaplasia and neoplasia of the female genital tract

Objective: Synchronous mucinous metaplasia and neoplasia of the female genital tract (SMMN-FGT) occurring at multiple sites during the same period of time is extremely rare, and the aim of this study was to investigate the clinicopathologic features of SMMN-FGT and its relationship with prognosis. Methods: We retrospectively analyzed the clinicopathological features and follow-up records of 25 cases of SMMN-FGT diagnosed from January 2012 to October 2022 in the case database of Obstetrics and Gynecology Hospital of Fudan University. Results: The mean and median age at onset were 47 and 46 years old, respectively. Clinical manifestations included irregular vaginal bleeding or drainage, pelvic pain, and ovarian cysts, etc. Germline genetic test confirmed Peutz-Jeghers syndrome (P-J syndrome) in two patients. All patients underwent surgery, and some had postoperative adjuvant radiotherapy and/or chemotherapy. The most frequent site of lesion was the cervix (21 cases), with 11, 10 and 16 cases occurring in the endometrium, fallopian tubes and ovaries, respectively. Six cases involved three sites simultaneously, and only one case had all four sites involved at the same time. Among the 9 cases with P53 mutation phenotype, 6 cases had gastric-type mucinous adenocarcinoma, 2 cases had lobular endocervical glandular hyperplasia, and 1 case had mucinous adenocarcinoma, whereas all the minimally deviated adenocarcinomas had wild phenotype of P53. The median follow-up time was 59 months, during which 3 cases died and 6 cases developed local recurrence or distant metastasis. According to our analysis, postoperative recurrence or metastasis was correlated with the FIGO stage of the disease, the number of lesion sites and the severe degree of the uterine lesions (P＜0.05). Conclusions: SMMN-FGT had a relatively good clinical prognosis, and even advanced patients could benefit from surgery and adjuvant therapy. In young patients, the ovaries may be preserved if no evidence of lesions were seen after adequate evaluation. In SMMN-FGT, gastric-type mucinous adenocarcinoma occurring in the cervix may have a better prognosis than gastric-type mucinous adenocarcinoma of the cervix alone, so the accurate diagnosis of SMMN-FGT is critical for clinical management.
