Recurrent implantation failure (RIF) remains a major challenge in assisted reproductive technology, and the molecular mechanisms underlying endometrial receptivity are incompletely understood. This study aimed to comprehensively characteriz…

Over 75% of failed pregnancies involve implantation defects. Growth factor receptor-bound protein 2 (GRB2) is an adaptor protein involved in signal transduction and cell communication. Here we show that the expression of GRB2 protein is low…

Levonorgestrel intrauterine-releasing system (LNG-IUS), an intrauterine device, is recommended for patients with adenomyosis; however, it often shows poor outcomes in these patients because of their large uterine size. This prospective stud…

This study analyzed transcriptome sequencing data from rat samples, categorized into control (normal), model (chronic endometritis, CE), and test (treated with Penning Formula, PNF) groups, to identify key target genes of PNF in CE treatmen…

BACKGROUND: Angiogenesis is a key link in a variety of physiological and pathological processes and plays a crucial role in tissue repair, tumor growth and ischemic diseases. Ginsenosides, as the main active component of ginseng, have a uni…

This study addresses the challenges in the early diagnosis of deep infiltrating endometriosis (DIE) by exploring the potential role of the deubiquitinating enzyme USP14. By analyzing the GSE141549 dataset from the Gene Expression Omnibus (G…

Serum biomarkers are often insufficiently sensitive or specific to facilitate cancer screening or diagnostic testing. In ovarian cancer, the few established serum biomarkers are highly specific, yet insufficiently sensitive to detect early-…

BACKGROUND: 0PN zygotes have a low cleavage rate, and the clinical outcomes of cleavage-stage embryo transfers are unsatisfactory. Blastocyst culturing is used to screen 0PN embryos, but whether the cell number of 0PN embryos on day 3 affec…

The vagina contains at least a billion microbial cells, dominated by lactobacilli. Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age, as well as cervical, fec…

PURPOSE: Progestin-primed ovarian stimulation (PPOS) is a new ovarian stimulation protocol that has been used over the last decade to enhance reproductive function. The purpose of this study is to evaluate whether PPOS is as effective as co…

BACKGROUND: Many studies have demonstrated the positive clinical value of progestin-primed ovarian stimulation (PPOS) in patients with polycystic ovary syndrome (PCOS) who underwent assisted reproductive technology. However, the underlying …

The purpose of this experiment is to establish a rat model of thin endometrium and to explore the effect of ligustrazine on the thin endometrium of rats. The thin endometrium model was made by using infusing absolute ethyl alcohol into the …

OBJECTIVE: Uterine carcinosarcomas (UCSs) are aggressive rare tumors recognized as malignancies composed of metaplastic transformation of epithelial elements. Nay no comprehensive molecular classification has been applied to UCS to guide ta…

BACKGROUND: The human uterus is traditionally believed to be sterile, while the vaginal microbiota plays an important role in fending off pathogens. Emerging evidence demonstrates the presence of bacteria beyond the vagina. However, a micro…

Acute pancreatitis (AP) is a complex disease that results in significant morbidity and mortality. For many decades, it has compelled researchers to explore the exact pathogenesis and the understanding of the pathogenesis of AP has progresse…

Reports on bacteria detected in maternal fluids during pregnancy are typically associated with adverse consequences, and whether the female reproductive tract harbours distinct microbial communities beyond the vagina has been a matter of de…

OBJECTIVE: To investigate the balance between regulatory T cells (Treg) and T-helper 17 cells (T(H)17) in peripheral blood and uteri of women with adenomyosis (AM), and to evaluate their potential correlation with dysmenorrhea and CA-125 le…

Human RON (Recepteur d'Origine Nantais) receptor tyrosine kinase is a cell surface receptor for Macrophage Stimulating Protein (MSP). RON mediates signal transduction pathways that regulate cell adhesion, invasion, motility and apoptosis pr…

Polycystic ovary syndrome (PCOS) is characterized by excessive theca cell androgen secretion, dependent upon LH, which acts through the intermediacy of adenosine 3', 5'-cyclic monophosphate (cAMP). cAMP signaling pathways are controlled thr…

Disclosed are compounds of the following formula, wherein the substituents are as defined in the specification. The compounds are GnRH receptor antagonists useful in the treatment of a variety of sex-hormone related conditions in both men a…

The discovery of novel uracil phenylethylamines bearing a butyric acid as potent human gonadotropin-releasing hormone receptor (hGnRH-R) antagonists is described. A major focus of this optimization was to improve the CYP3A4 inhibition liabi…

Suppression of the hypothalamic-pituitary-gonadal axis by peptides that act at the GnRH receptor has found widespread use in clinical practice for the management of sex-steroid-dependent diseases (such as prostate cancer and endometriosis) …

Recent success in the search for orally active gonadotropin-releasing hormone antagonists for the treatment of sex hormone-related diseases, such as endometriosis, uterine fibroids and prostate cancer, has resulted in the discovery of non-p…
