(Submitter supplied) The granulosa cells in the mammalian ovarian follicle respond to gonadotropin signalling and are involved in the processes of folliculogenesis and oocyte maturation. Studies on gene expression and regulation in human granulosa cells are of interest due to their potential for estimating the oocyte viability and IVF success. The current study determined the mRNA profile by deep sequencing of the two intrafollicular somatic cell types: mural and cumulus granulosa cells isolated from women undergoing controlled ovarian stimulation and in vitro fertilization.

(Submitter supplied) The granulosa cells in the mammalian ovarian follicle respond to gonadotropin signalling and are involved in the processes of folliculogenesis and oocyte maturation. Studies on gene expression and regulation in human granulosa cells are of interest due to their potential for estimating the oocyte viability and IVF success. However, the post-transcriptional gene expression studies on miRNA level in the human ovary have been scarce. more...

(Submitter supplied) MicroRNAs (miRNAs) have known roles in the post-transcriptional regulation of various biological processes including ovarian follicle development. We have previously identified from human pre-ovulatory granulosa cells miRNAs that are expressed from the intronic regions of two key genes in normal follicular development: FSH receptor (FSHR) and CYP19A1, the latter encoding the aromatase enzyme. In the present study, we aim to identify the targets regulated by those two miRNAs: hsa-miR-548ba and hsa-miR-7973, respectively. more...

(Submitter supplied) Cumulus cells are biologically distinct from other follicular cells and perform specialized roles, transmitting signals within the ovary and supporting oocyte maturation during follicular development. The bi-directional communication between the oocyte and the surrounding cumulus cells is crucial for the acquisition of oocyte competence. Using Illumina/deep-sequencing technology, we dissected the small RNAome of pooled human mature MII oocytes and cumulus cells.

(Submitter supplied) Development of ovarian follicles is controlled at the molecular level by several gene products whose precise expression leads to regression or ovulation of follicles. MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression through sequence-specific base pairing with target messenger RNAs (mRNAs) causing translation repression or mRNA degradation. The aim of this study was to identify miRNAs expressed in ovarian follicles, localize their expression within the theca and/or granulosa layers and their putative target genes/pathways that are involved in bovine ovarian follicle development. more...

(Submitter supplied) miRNA played an important role in the process of carcinogenesis in HBV related hepatocellular carcinoma. Therefore, we performed miRNA microarray to evaluate the miRNAs that expressed differentially between HCC tumor versus non-tumor liver tissues.

(Submitter supplied) Cell-free RNAs have been used as diagnostic disease markers describing the state of tissue environment. The origin and potential functions of such RNAs in human pre-ovulatory follicle, the environment of oocyte maturation, are unclear. We aimed to describe the small RNA profiles of three follicular compartments of the same follicle: mural granulosa cells (MGC), cell-free follicular fluid (FF) and extracellular vesicles (EV) of the FF. more...

(Submitter supplied) Ovulatory dysfunction affects nearly 40% of women of reproductive age that are struggling with infertility. Ovulation is the culmination of a complex and long process during which most follicles undergo atresia instead of developing into preovulatory follicles. The rescue of follicles from atresia and their maturation towards ovulatory competence requires “a pas de deux” between endocrine and locally-produced factors. more...

(Submitter supplied) Communication between various ovarian cell types is a prerequisite for folliculogenesis and ovulation. In antral follicles granulosa cells divide into two distinct populations of mural (MGC) and cumulus granulosa cells (CGC), enveloping the antrum and surrounding the oocyte, respectively. IVF offers a good opportunity for analysing their functional properties since granulosa cells can be retrieved during the puncturing procedure of stimulated follicles. more...
