Abstract

Background

A variety of pathways target CDKI p21^WAF1/CIP1 expression at transcriptional, post-transcriptional as well as translational levels. We previously found that cell growth suppressing retinoid CD437 enhanced expression of p21^WAF1/CIP1 and DNA damage inducible GADD45 proteins in part by elevating their mRNA stability.

Results

Here, we investigated molecular mechanisms of CD437-dependent post-transcriptional regulation of p21^WAF1/CIP1 expression. By utilizing MDA-MB-468 HBC cells expressing chimeric rabbit β-globin-p21^WAF1/CIP1 transcripts we mapped multiple CD437-responsive sequences located within positions 1195 to 1795 of the 3'-untranslated region of p21^WAF1/CIP1 mRNA. Several cytoplasmic proteins present in MDA-MB-468, MCF-7 HBC as well …
