Regulation of cyclin‐dependent kinase inhibitor p21WAF1/Cip1/Sdi1 gene expression in hepatic regeneration
J H Albrecht, A H Meyer, M Y Hu – 30 December 2003 – WAF1/Cip1/Sdi1 (p21) is the prototype of a family of proteins that inhibit cyclin‐dependent kinases and regulate cell cycle progression in eukaryotic cells. In addition to normal cell cycle progression, p21 is involved in growth suppression mediated by p53 and transforming growth factor β (TGFβ), differentiation, and apoptosis. To gain insight into the possible involvement of p21 in liver cell growth, the expression and regulation of the p21 gene was evaluated in rodent models of liver regeneration and specimens of human liver diseases.
