[HTML][HTML] C/EBPα arrests cell proliferation through direct inhibition of Cdk2 and Cdk4

…, A Welm, T Goode, WJ Roesler, NA Timchenko - Molecular cell, 2001 - cell.com
The transcription factor CCAAT/enhancer binding protein α (C/EBPα) is a strong inhibitor of
cell proliferation. We found that C/EBPα directly interacts with cdk2 and cdk4 and arrests cell …

CCAAT/enhancer-binding protein alpha (C/EBP alpha) inhibits cell proliferation through the p21 (WAF-1/CIP-1/SDI-1) protein.

[HTML][HTML] Aging reduces proliferative capacities of liver by switching pathways of C/EBPα growth arrest

P Iakova, SS Awad, NA Timchenko - Cell, 2003 - cell.com
The liver is capable of completely regenerating itself in response to injury and after partial
hepatectomy. In liver of old animals, the proliferative response is dramatically reduced, the …
