A correlation study of the expression of HA-CD44st and HER-2 in breast cancer

Abstract

Binding of HA to the CD44st receptor may regulate the invasiveness of MCF-7 cells through the CD44st/TGFβ/PI3K/AP-1 signaling pathway with increased expression of TGFβ and HER-2. The expression of CD44st mRNA is correlated with HER-2 expression in postoperative breast cancer patients.
