KLF15 negatively regulates estrogen-induced epithelial cell proliferation by inhibition of DNA replication licensing.
In the epithelial compartment of the uterus, estradiol-17β (E(2)) induces cell proliferation while progesterone (P(4)) inhibits this response and causes differentiation of the cells. In this study, we identified the mechanism whereby E(2) and P(4) reciprocally regulate the expression of minichromosome maintenance (MCM)-2, a protein that is an essential component of the hexameric MCM-2 to 7 comp...
متن کاملDUSP5 and DUSP6 modulate corneal epithelial cell proliferation
PURPOSE Dual specificity phosphatases (DUSPs) modulate the duration and magnitude of phospho-activation of Erk1/2, p38 and JNK1/2, the terminal kinases (TKs) of the mitogen activated protein kinase (MAPK) cascades. Three DUSPs, DUSP1, DUSP5, and DUSP6, are overexpressed in ocular surface side population stem cells (SPSCs). Our objective was to identify the impact of these enzymes on TK phosphor...
متن کاملCDK5 regulates cell adhesion and migration in corneal epithelial cells.
CDK5 and its activator, p35, are expressed in mouse corneal epithelium and can be coimmunoprecipited from corneal epithelial cell lysates. Immunostaining shows CDK5 and p35 in all layers of the corneal epithelium, especially along the basal side of the basal cells. Stable transfection of corneal epithelial cells with CDK5, which increases CDK5 kinase activity by approximately 33%, also increase...
متن کاملMyostatin negatively regulates satellite cell activation and self-renewal
Satellite cells are quiescent muscle stem cells that promote postnatal muscle growth and repair. Here we show that myostatin, a TGF-beta member, signals satellite cell quiescence and also negatively regulates satellite cell self-renewal. BrdU labeling in vivo revealed that, among the Myostatin-deficient satellite cells, higher numbers of satellite cells are activated as compared with wild type....
متن کاملTAT-mediated protein transduction into human corneal epithelial cells: p15(INK4b) inhibits cell proliferation and stimulates cell migration.
PURPOSE The cell cycle inhibitor p15(INK4b) has been localized in migrating corneal epithelial cells. In this study, TAT-fusion protein technology was used to transduce p15(INK4b) into human corneal epithelial cells to examine the effect on cell proliferation and migration. METHODS Human p15(INK4b), obtained by RT-PCR, was cloned into a TAT-HA vector, and the fusion protein was purified from ...
