Summary: This research found that the expression of miR-142-3p and miR-598-3p, which are associated with polycystic ovary syndrome (PCOS), differs significantly between women with PCOS and those without. These circulating miRNAs, when combined with easily available measurements such as waist-to-hip ratio (WHR) and circulating LH-to-FSH (LH/FSH) ratios, can effectively distinguish between women with and without PCOS.

Summary: In this study, it was found that miR-143-3p and miR-155-5p antagonistically regulate glycolytic-mediated follicular dysplasia of granulosa cells (GCs) in polycystic ovary syndrome (PCOS), and HK2 is the mediator of this regulation.

Summary: This study revealed that miR-130b-3p overexpression or SMAD4 silencing can promote KGN cell proliferation, induce S phase arrest, inhibit apoptosis and caspase-3 activity; conversely, miR-130b-3p inhibitors reduce proliferation, inhibit apoptosis and reverse the effect of si-SMAD4.

Summary: This study investigated the role of histone deacetylase 1 (HDAC1) in granulosa cell (GC) pyroptosis induced by polycystic ovary syndrome (PCOS). The results showed that upregulation of HDAC1 could attenuate ovarian damage and hormone disorders in PCOS mice and suppress pyroptosis in ovarian tissues and HGL5 cells. Furthermore, HDAC1 inhibited GC pyroptosis through deacetylation to regulate the H19/miR-29a-3p/NLRP3 axis.

Summary: GC proliferation is essential for ovulation in animals, and DENND1A is identified as a significant factor in polycystic ovary syndrome. The study demonstrates that chi-miR-324-3p inhibits GC proliferation by targeting DENND1A, as validated through various experiments.

Summary: This study revealed that NEAT1 and BRD3 were highly expressed in patients with PCOS and PCOS mice, while miR-324-3p was lowly expressed. Lowering NEAT1 levels or increasing miR-324-3p levels could alleviate metabolic disorders and ovarian pathologies in PCOS mice.

Summary: Female infertility is mainly caused by ovulation disorders, with polycystic ovary syndrome (PCOS) being the most prevalent. PCOS is associated with abnormal function of estrogen and estrogen receptors (ERs), affecting cellular activities. Selective estrogen receptor modulators (SERMs) like tamoxifen and clomiphene have shown clinical applications for subfertility with PCOS, but further understanding of the role of ER in PCOS is needed.

Summary: The study reveals that adipocyte-derived extracellular vesicles containing miR-26b inhibit viability and promote apoptosis in cumulus cells, disrupting ovary ovulation and hormone levels. These findings suggest a novel signaling pathway in the development of PCOS and potential new therapeutic strategies.

Summary: LINC00477 is significantly upregulated in the serum of PCOS patients as well as PCOS mouse models. LINC00477 overexpression inhibited the proliferation and promoted the apoptosis of granulosa cells, while knockdown of LINC00477 had the opposite effects. Additionally, miR-128 mimics partially abrogated the effect of LINC00477 on granulosa cells.

Summary: This study found that in polycystic ovary syndrome (PCOS), TMPO-AS1 is increased while mature miR-355-5p is decreased. TMPO-AS1 can suppress the maturation of miR-335-5p, leading to increased cell proliferation.

Summary: This study investigated the functions and potential molecular mechanism of LINC01296 in the progression of cutaneous malignant melanoma (CMM) through the regulation of the miR-324-3p/MAPK1 axis. The up-regulation of LINC01296 was found in CMM tissues and cell lines, and its over-expression promoted cell proliferation in CMM cell lines. Further investigations revealed that LINC01296 interacted with miR-324-3p and that MAPK1 was the target mRNA of miR-324-3p. Rescue experiments suggested a positive regulatory association between LINC01296 and MAPK1 in CMM cells.
