Project description:Neurotensin (NTS) is a small 13 amino acid neuropeptide. In the mouse ovary, the expression of Nts ovary increases 250-fold 4h after hCG. Similarly, in granulosa cells, the mRNA levels of Nts increased rapidly at 4h after hCG stimulation. Interestingly, the Nts mRNA levels in granulosa cells were approximately 8-fold higher at 4 h after hCG than in whole ovaries. However, the potential mechanisms of NTS action in the ovulatory process are unknown. The present study determined the regulatory mechanisms driving the expression of Nts and functions of the NTS using primary mouse granulosa cells. hCG activated PKA and p38MAPK signaling pathways, and inhibitors for these pathways abolished hCG-induced increases in the levels of Nts. To identify the genes regulated by NTS, high throughput RNA sequencing was performed using Nts silenced mouse granulosa cells treated with or without hCG. Sequencing data analysis revealed that Nts knockdown affects the expression of several genes that were not previously identified in the ovary. qPCR analysis verified hCG-induced, Nts-regulated expression of a selection of these genes. This study revealed novel genes regulated by NTS, thereby providing a function for NTS in the ovulatory process.

Project description:An appendix to the published Gaulton et al. work (PMID: 20118932; E-GEOD-17616). In the original paper, the authors note that samples 1 and 2 are not as pure as the third sample. This appendix provides FAIRE-Seq data obtained from a purified islet sample to replace the problematic published data. The goal of the original experiment was to identify active regulatory DNA in human pancreatic islets. This was accomplished using high-throughput sequencing of genomic regions isolated using FAIRE from three purified pancreatic islet samples to identify sites of open chromatin.

Project description:We report the application of H3K9ac- and H4K16ac-based sequencing technology for high-throughput profiling of histone modifications in human granulosa KGN cells. By obtaining over four billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of KGN cells. We find that H3K9ac effectively discriminates genes that are influenced by butyrate treatment. H4K16ac described less influence of genes by butyrate treatment. Finally, we show that butyrate could mediate the H3K9ac to effectively influence genes that related to biological functions ang signalings. This study provides a framework for the application of comprehensive gene profile towards H3K9ac regulation by butyrate in human granulosa KGN cells.

Project description:This group consist of human embryologists from the reproductive medical center for of the 1st affiliated hospital of Anhui Medical University. Our research is specifically focused on women ovarian reserve and the relevant female infertility. By deep sequencing, the current experiment determined the small non-coding RNA profile of cumulus cells from patients with or without diminished ovarian reserve undergoing controlled ovarian stimulation and in vitro fertilization treatment. Ovarian follicles, which are a densely-packed shell of granulosa cells that contains an immature or mature oocyte, are above all responsible for the development, maturation, and release of mature egg for fertilization. They are also responsible for synthesizing and secreting hormones that are essential for follicular development, menstrual and estrous cycle, maintenance of the reproductive tracts and their functions, development of female secondary sex characteristics, and metabolism. During folliculogenesis, ovarian granulosa cells surrounding the oocyte differentiate into mural granulosa cells, involved in gonadal steroidogenesis, and into cumulus cells, which are ovulated with the oocyte at ovulation. In the present study, we described the small non-coding RNA expression profile to characterize the ensemble of both known and novel ncRNAs expressed in cumulus cells from patients with or without Diminished ovarian reserve, by using high-throughput Solexa technology.

Project description:We report the application of RNA sequencing technology for high-throughput profiling of gene expression in YAP2SA-lentivirus-infected adult human dental pulp stromal cells (hDPCs).To overexpress YAP2SA in hDPCs we transfected cells with YAP2SA-lentivirus. Cells were derived from a 18~22-year-old healthy male human donor. Total mRNA was collected using TRIzol ® (Invitrogen, CA, USA) solution. Then all the extraction procedures were conducted according to manufacture’s instructions for RNA extraction from homogenized tissues. After quality checks they were subjected to the high-throughput RNA-sequencing. Every group consists of 3 replicates which were from 3 independent experimental repeats.
