Project description:In the present study through TLDA analysis we looked into the miRNA differential expression in peripheral blood of PCOS patients v/s control women. The results implicated that many signalling networks as MAPK pathway, Androgen signaling, Insulin signaling and Immune signaling are regulated in peripheral blood of PCOS patients. The data indicate that there is generic PCOS specific gene expression in peripheral blood of PCOS subjects which can reflect the same from other PCO tissues. Total RNA was extracted from peripheral blood of 4 PCOS patients and 4 control subjects and compared for miRNA diferential expression through TLDA

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. Six pooled RNAs from CC samples (three PCOS and three non-PCOS pooled RNAs) were separately analyzed on 6 GeneChip miRNA 2.0 Array (miRBase V15)

Project description:We report the miRNA expression in each CD34+ cells and their exosomes in mobilized peripheral blood in aged, young, and aged/young samples cocultured in transwell. Restored samples refer to aged MPB co-cultured with young MPB in the transwell culture.
Project description:Chronic Fatigue Syndrome (CFS/ME) is a complex multisystem disease, with a pathogenesis that is undetermined. A large cohort of genes demonstrating altered expression in CFS/ME implicates the role of translational regulatory molecules, microRNA (miRNA), in the pathogenesis of this disease. We aimed to define the changes in microRNA expression in peripheral blood mononuclear cell (PBMC) samples in CFS/ME patients. miRNA expression was analysed in PBMC samples taken from CFS/ME patients and healthy controls, using the Ambion Bioarray V1. miRNA demonstrating differential expression were validated by qRT-PCR and analysed in an independent patient cohort in fractionated blood cell populations. The targets of miRNA hsa-miR-99b and hsa-miR-330-3p were then identified by gene expression analysis after transfection into primary NK cells.Microarray analysis identified differential expression of 34 miRNA, all of which were up-regulated. Four of the 34 miRNA had confirmed expression changes by qRT-PCR. Fractionating PBMC samples by cell type from an independent patient cohort identified changes in miRNA expression in NK-cells, B-cells and monocytes with the most significant abnormalities occurring in NK cells. Transfecting primary NK cells with hsa-miR-99b and hsa-miR-330-3p, respectively, resulted in gene expression changes consistent with NK cell activation and diminished cytotoxicity.This study demonstrates altered microRNA expression in the peripheral blood mononuclear cells of CFS/ME patients, which are potential diagnostic biomarkers. The greatest degree of miRNA deregulation was identified in NK cells with targets consistent with cellular activation and altered effector function.
Project description:Why ~70% of women with polycystic ovary syndrome (PCOS) have intrinsic insulin resistance (IR), above and beyond that associated with body mass, including dysfunctional glucose metabolism in adipose tissue (AT), remains a fundamental question. In these experiments, we sought to explore the role of miRNAs in the AT of PCOS and matched controls. Analysis determined that PCOS AT has a differentially expressed miRNA profile, including upregulated miR-93. We observed a significant association between HOMA-IR, and GLUT4 and miR-93 expression in human AT. Our results point to a novel mechanism for regulating insulin-stimulated glucose uptake via miR-93, and demonstrate upregulated miR-93 expression in PCOS, possibly accounting for the IR of the syndrome, and also in non-PCOS women with IR. We performed miRNA microarrays to determine PCOS-related miRNA expression in adipose derived from lean PCOS patients and matched control women. We analyized miRNA from total RNA extracted from subcutaneous (sc) adipose tissue from three lean PCOS patients and three matched control women.
