Prolyl Isomerase Pin1 Regulates Mouse Embryonic Fibroblast Differentiation into Adipose Cells

Prolyl Isomerase Pin1 Regulates Mouse Embryonic Fibroblast Differentiation into Adipose Cells

BACKGROUND A peptidyl prolyl cis/trans isomerase, Pin1, regulates insulin signal transduction. Pin1 reduces responses to insulin stimulation by binding CRTC2 (CREB-regulated transcriptional co-activator 2) and PPARγ (peroxisome prolifereator- activated receptor γ), but conversely enhances insulin signaling by binding IRS-1 (insulin receptor substrate-1), Akt kinase, and Smad3. Therefore, it is ...

The Peptidyl-Prolyl Isomerase Pin1 Regulates

Differentiation of Mouse Embryonic Stem Cells into Hematopoietic Cells

Purpose: Differentiation of Mouse embryonicstem cells into Hematopoietic cells. Materials and Methods: In this study, we used EB formation system for Hematopoietic differentiation of mouse embryonic stem cell (Royan B1) in suspension culture. EBs cultured in medium with Hematopoietic inducer cytokines (SCF, TPO, GMCSF, IL3, Flt3 and EPO) .presence of hematopoietic differentiated cell assessed ...

Pin1 prolyl isomerase regulates endothelial nitric oxide synthase.

OBJECTIVE The Pin1 prolyl isomerase acts in concert with proline-directed protein kinases to regulate function of protein substrates through isomerization of peptide bonds that link phosphoserine or phosphothreonine to proline. We sought to determine whether Pin1 interacts with endothelial nitric oxide synthase (eNOS) in endothelial cells in a manner that depends on proline-directed phosphoryla...

The peptidyl-prolyl isomerase Pin1 regulates cytokinesis through Cep55.

Failure of cytokinesis results in tetraploidy and can increase the genomic instability frequently observed in cancer. The peptidyl-prolyl isomerase Pin1, which is deregulated in many tumors, regulates several processes, including cell cycle progression. Here, we show a novel role for Pin1 in cytokinesis. Pin1 knockout mouse embryonic fibroblasts show a cytokinesis delay, and depletion of Pin1 f...
