Decreased levels of CD44 protein and mRNA in prostate carcinoma: Correlation with tumor grade and ploidy

Abstract

PACS exhibit down-regulation of CD44 protein expression, which correlates with high tumor grade and aneuploidy. v6 and v3 isoforms were preferentially expressed in the basal cells of benign prostatic acini. Based on a subset of cases, loss of CD44 protein expression is associated with decreased abundance of CD44 mRNA.
