Project description:Differential genes in adipocytes induced from polycystic ovary syndrome-derived and non- polycystic ovary syndrome-derived human embryonic stem cells
Project description:Aberration in miRNA expression or DNA methylation is a causal factor for numerous pathological conditions including polycystic ovarian syndrome PCOS, a common endocrine disorders and leading cause of infertility. The epigenetic interactions between miRNA and DNA methylation remain unexplored in PCOS. Few studies have reported that the regulation of miRNAs in polycystic ovary syndrome(PCOS). Our study helps to understand the molecular pathogenesis of PCOS in human ovarian granulosa cells from the perspective of post-transcriptional level.
Project description:To reveal microRNAs expression differences in cumulus cells between polycystic ovary syndrome (PCOS) and non-PCOS women. miRNAs expression profile of the cumulus cell samples with PCOS and non-PCOS were determined by Affymetrix miRNA 2.0.
Project description:To investigate the etiology of the hyperandrogenic phenotype of polycystic ovary syndrome (PCOS), a prenatally androgenized (PNA) mouse model was validated and used for microarray analysis.
Project description:As a heterogeneous reproductive disorder with unclear etiopathogenesis, polycystic ovary syndrome (PCOS) can be caused by genetic, diet, and environmental factors. Bisphenol A (BPA), a global environmental contaminant, can induce PCOS and NAFLD due to direct exposure; however, whether these phenotypes persist in future unexposed generations is not currently understood. We observed genes abnormally expressed in the ovary of BPA lineage, similar to human PCOS patients. IPA analyses revealed activation of the cancerous pathway, arginine-proline metabolism, insulin signaling, AMPK, and HOTAIR regulatory pathways, as well as upstream regulators esr1 and tgf β.
