EGF Regulation of Nuclear Co-Activator AIB1 Function in Breast Cancer

Abstract

Various growth factor receptor pathways promote human breast tumorigenesis of hormone-independent tumors. The nuclear receptor coactivator AIBi (amplified in breast cancer 1) can be phosphorylated and regulated by growth factor-induced signaling pathways such as MAP kinase and IkB kinase. Our lab has found a splice variant of AIBl, called delta exon3 AIBl, which has a higher co-activating ability than the full-length protein. This study determined the ability of delta exon3 splice variant compared with AIBi in potentiating growth factor signaling and to determine the mechanism of this potentiation using a growth factor responsive promoter.
