Cyclin-dependent kinase inhibitor (CDKN1A), often referred to as p21(Waf1/Cip1) (p21), is induced by a variety of environmental stresses. Transcription factor ELK-1 is a member of the ETS oncogene superfamily. Here, we show that ELK-1 directly trans-activates the p21 gene, independently of p53 and EGR-1, in sodium arsenite (NaASO(2))-exposed HaCaT cells. Promoter deletion analysis and site-directed mutagenesis identified the presence of an ELK-1-binding core motif between -190 and -170 bp of… CONTINUE READING
