Myc (c-Myc) counteracts p27 effects, and low p27 usually correlates with high Myc expression in human cancer. However there is no information on the co-expression of both genes in chronic lymphocytic leukemia (CLL). We found a lack of correlation between RNA and protein levels of p27 and Myc in CLL cells, so we determined the protein levels by immunoblot in 107 cases of CLL. We observed a high ...
p27 acts as a critical negative regulator of the cell cycle by inhibiting the activity of cyclin/cdk complexes during G0 and G1. Degradation of p27 is a critical event for the G1/S transition and occurs through ubiquitination by SCF(Skp2) and subsequent degradation by the 26S-proteasome. A tumor suppressing function of p27 has been demonstrated in mouse models and studies of human tumors. More ...
This report describes the 2,032,158-bp draft genome sequence of Lactobacillus sakei (L. sakei) strain FBL1, isolated from mukeunji purchased at the Gwangju World Kimchi Culture Festival in 2012, South Korea. The total draft genome size was 2,032,158 bp with a G+C content of 41.2%.
Vascular smooth muscle cell proliferation plays a major role in the development of numerous vascular pathologies. Understanding the molecular mechanisms that regulate smooth muscle cell proliferation is therefore essential for the development of new therapies for the treatment of these pathologies. Skp2 is an F-box protein component of the SCFSkp2 ubiquitin-ligase that controls cellular prolife...
OBJECTIVE Beta-cell proliferation is an important mechanism underlying beta-cell mass adaptation to metabolic demands. We have examined effects, in particular those mediated through intracellular cAMP signaling, of the incretin hormone analog exendin-4 on cell cycle regulation in beta-cells. RESEARCH DESIGN AND METHODS Changes in islet protein levels of cyclins and of two critical cell cycle ...
Cellular and molecular pathways link thrombosis and innate immune system during sepsis. Extrinsic pathway activation of protease thrombin through FVIIa and tissue factor (TF) in sepsis help activate its endothelial cell (EC) membrane Protease Activated Receptor 1 (PAR-1). Thrombin adjusts the EC cycle through activation of G proteins (G12/13), and later through Rho GEFs (guanine nucleotide exch...
OBJECTIVE To examine whether oncogenic Ras affects transforming growth factor (TGF)-beta-mediated cell-cycle arrest in hematopoietic cells and the downstream signal transduction pathway involved in the interference with TGF-beta-induced cell-cycle arrest. MATERIALS AND METHODS Two leukemic cell lines bearing N-Ras(L61) mutations; HL-60 and TF-1, and the M1 cell line with wt Ras were investiga...
