Association between MUC1 gene polymorphism and expected progeny differences in Nelore cattle (Bos primigenius indicus)
MUC1 is a heavily glycosylated mammalian transmembrane protein expressed by mucosal secretory tissues for both protection against microbial infection and lubrication. An important characteristic of MUC1 is its variable number of tandem repeats (VNTR) containing several sites for O-glycosylation. VNTR length has been associated with many human diseases and with certain economically important tra...
متن کاملFollicle-stimulating hormone regulates expression and activity of epidermal growth factor receptor in the murine ovarian follicle.
Fertility depends on the precise coordination of multiple events within the ovarian follicle to ensure ovulation of a fertilizable egg. FSH promotes late follicular development, including expression of luteinizing hormone (LH) receptor by the granulosa cells. Expression of its receptor permits the subsequent LH surge to trigger the release of ligands that activate EGF receptors (EGFR) on the gr...
متن کاملFollicle Stimulating Hormone Receptor (FSHR) Gene and Postmenopausal Epithelial Ovarian Cancer (EOC)
Objective: Follicle stimulating hormone receptor (FSHR) is expressed not only in granulosa cells of ovary but also in ovarian surface epithelium (OSE) and in benign and malignant epithelial ovarian tumors. The significance of this expression has remained unexplained so far. This transmembrane receptor is involved in G protein linked signal transduction and causation of neo-plasia. These finding...
متن کاملEffect of Human Ovarian Tissue Vitrification/Warming on the Expression of Genes Related to Folliculogenesis
Background: Ovarian tissue cryopreservation is an alternative strategy to preserve the fertility of women predicted to undergo premature ovarian failure. This study was designed to evaluate the expression of folliculogenesis-related genes, including factor in the germline alpha (FIGLA), growth differentiation factor-9 (GDF-9), follicle-stimulating hormone receptor (FSHR), and KIT LIGAND after v...
متن کاملFSH and eCG impact follicles development and expression of ovarian FSHR and caspase-9 in mice
The study aimed to investigate the effects of FSH and eCG on the ovarian and follicular development, expression levels of FSHR and caspase-9 of ovaries in vivo. One hundred and five prepuberty mice were allocated into FSH-1, FSH-2, FSH-3, eCG-1, eCG-2, eCG-3 groups and control group (CG). Mice in FSH-1, FSH-2 and FSH-3 were intramuscularly injected with 5, 10 and 20 IU FSH twice (on day 0 and 4...
