Abstract
Background: Tumor Protein p53 (p53), cyclin-dependent kinase inhibitor 1A (p21/WAF1), and
murine double minute 2 (MDM2) participate in the regulation of ... found in malignant tumors and has been associated with poor
prognosis. Our aim was to investigate the expression of the 3 proteins in hepatocellular carcinoma
(HCC) and their prognostic significance.
Methods: ... examined p53, p21/WAF1, and MDM2 expression in 181 pairs of HCC tissues and
the adjacent hepatic tissues by performing immunohistochemistry and examined the expression of
the 3 proteins in 7...
