Project description:Soleus muscle has the most abundant H19 expression compared to other skeletal muscle tissues. In order to identify genes regulated by long noncoding RNA H19 in skeletal muscle, we performed RNA-Seq with dissected WT and H19KO soleus muscles from 21 week old mice. Among the differentially expressed genes, we found skeletal muscle - overexpressed gene DUSP27, which potentially plays an important role in regulating skeletal muscle glucose metabolisim by regulating the activitiy of AMPK, might be a target of H19 mediated regulation.

Project description:Dystrophin proteomic regulation in Muscular Dystrophies (MD) remains unclear. We report that a long noncoding RNA (lncRNA) H19 associates with dystrophin. To investigate the biological roles of this interaction in vivo, we performed mass spectrometry analysis of dystrophin and its associated proteins in H19-proficient and -deficient C2C12 myotubes. Mass spectrometry data indicated that in H19-proficient myotubes, dystrophin associates with components of dystrophin-associated protein complex (DPC); however, in H19-deficient myotubes, dystrophin associated with UBA1, UB2G1, TRIM63 ubiquitin E3 ligase and ubiquitin. In H19-deficient myotubes, dystrophin was post-translationally modified with K48-linked poly-ubiquitination at Lys3577 (referred to as Ub-DMD). This mass spectrometry study demonstrated that lncRNA H19, associates with dystrophin and inhibits E3 ligase-dependent Ub-DMD formation and its subsequent proteasomal degradation. Based on this study, H19 RNA oligonucleotides conjugated with a muscle homing ligand Agrin (referred to as AGR-H19) and Nifenazone, a TRIM63-specific small molecule inhibitor, reverses the dystrophin degradation in iPSC-derived skeletal muscle cells from Becker Muscular Dystrophy patients. Furthermore,treatment of mdx mice with exon-skipping reagent, in combination with either AGR-H19 or Nifenazone, dramatically stablized dystrophin, preserved skeletal/cardiac muscle histology, and improved strength/heart function. In summary, this mass spectrometry study paves the way to meaningful targeted therapeutics for BMD and certain DMD patients.

Project description:Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disease characterized by persistent anovulation and hyperandrogenism, affecting approximately 8%-10% of women of childbearing age and occupying an important position in the etiology of infertility. There is increasing evidence that lncRNAs are involved in the development of PCOS, but the potential regulatory mechanism is still unclear. This study performed high-throughput lncRNA sequencing of follicular fluid exosomes in non-PCOS infertility patients and PCOS infertility patients. The sequencing results led to the identification of 1253 upregulated and 613 downregulated lncRNAs from a total of 1866 detected candidates. There was no significant difference between the PCOS patients and non-PCOS patients in body mass index (BMI) or the fasting blood glucose (FBG) level. However, luteinizing hormone (LH), estradiol (E2), testosterone (T), serum prolactin (PRL) and anti-Mullerian hormone (AMH) levels were clearly upregulated in PCOS patients compared to those in non-PCOS patients. There was also an increase in LH/FSH (>2) in the PCOS patients. Functional analysis showed that the functions of lncRNAs were related to adenine metabolism, adenine biosynthesis and cytidine triphosphate biosynthesis. These results suggest that lncRNAs may play an important role in the pathogenesis of PCOS and may be potential targets for the diagnosis and treatment of PCOS.

Project description:We used high throughput sequencing to compare the differential gene expression of HepG2 cells with and without H19 knockdown. We found critical genes involved in glucose production changed significantly after H19 konckdown compared to control.

Project description:Ovarian follicular granulosa cells surround and nurture oocytes, and produce sex steroid hormones. It is believed that during development the ovarian surface epithelial cells invaginate into the ovary and develop into granulosa cells when associating with oogonia to form follicles. Using bovine fetal ovaries (n = 53) we identified a novel cell type, termed GREL for Gonadal Ridge Epithelial-Like. Using 25 markers for GREL and other cells we conducted immunohistochemistry and electron microscopy and chronologically tracked all somatic cell types during development. Before 70 days of gestation the gonadal ridge/ovarian primordium is formed by proliferation of GREL cells at the surface epithelium of the mesonephros. Primordial germ cells (PGCs) migrate into the ovarian primordium. After 70 days, stroma from the underlying mesonephros begins to penetrate the primordium, partitioning the developing ovary into irregularly-shaped ovigerous cords composed of GREL cells and PGCs/oogonia. Importantly we identified that the cords are separated from the stroma by a basal lamina. Around 130 days of gestation as the stroma expands laterally below the GREL cells on the surface thus establishing a sub-epithelial basal lamina and an epithelial-stromal interface, and it is at this stage that a mature surface epithelium develops from the GREL cells. The stroma continues to partition the ovigerous cords into smaller groups of cells eventually forming follicles containing an oogonium/oocyte surrounded by GREL cells, which become granulosa cells. Thus in contrast to the prevailing theory, the ovarian surface epithelial cells do not invaginate into the ovary to form the granulosa cells of follicles. Microarray analysis of gene expression was conducted on different cell types cultured from fetal ovaries to identify possible markers of somatic cells during development. Two different cell types: Gonadal Ridge Epithelial-Like cells (n=2, 130 days gestation) and adult fibroblasts (n=1) were cultured from digested bovine fetal ovaries and gene expression compared with each other by Bovine Genome Affy array analysis in Partek Genomics Suite software, to identify possible markers of somatic cells during development.

Project description:Anti-müllerian hormone (AMH) has an inhibitory effect on ovarian follicle development. However, the mechanism by which AMH regulates folliculogenesis remains to be elucidated. In this study we aimed to investigate the changes in transcriptome of preantral to small antral mice follicles after culturing with AMH and thereby identify candidate genes to be involved. Preantral to small antral follicles were collected from dissected ovaries from six to eight weeks old female C57BL/6Tac mice. Twelve hour as well as 24 hour experiments were performed in two different concentrations of AMH. The experiments were performed in triplicate. In total 18 samples: 3 x conc. of AMH, 2 x time points, 3 x experiments (triplicate). Samples are comparable within each experiment, that is, sample 1-3 or 4-6 or 7-9 or 10-12 or 13-15 or 16-18.

Project description:This study describes a temporal profile of gene expression from normal human fetal testes and ovaries. Gonads from 34 fetuses between 9 weeks and 20 weeks of gestation were obtained from the Department of Pathology and the Birth Defects Research Laboratory at the University of Washington. Relative transcript levels were determined using the Affymetrix Human Genome U133A Plus 2.0 arrays. Sex determination occurs in the human gonad at approximately 6 weeks; gestation with development of the testis driven by expression of SRY. In this study, SRY transcript was present and elevated at 9 weeks gestation in the testis but absent in the ovary. The transcript levels of other testis-specific factors SOX9, AMH, and the steroidogenic genes CYP17a1, CYP11a1, STAR and HSD17β3 were all significantly higher in the testis. In contrast, transcripts known to be involved in meiosis including STRA8, SPO11, SYCP3, TEX11, TEX14 and STAG3 showed highest expression in the fetal ovary beginning at week 12. These gene expression profiles will be a resource for understanding and defining normal gonad development and provide the opportunity to dissect abnormal development. Experiment Overall Design: Gonads from 34 fetuses between 9 weeks and 20 weeks of gestation were obtained, total RNA was extracted and hybridized to Affymetrix microarrays.
