In premenopausal women with ER+/HER2- breast cancer, the neoadjuvant EVANGELINE trial is testing the hypothesis that dual targeting of ER and PKC beta will result in substantial anti tumor activity without the need for ovarian function suppression https://t.co/ljrKlYlqxg
Endoxifen is known to be a more potent inhibitor of ER alpha compared to tamoxifen. Based on an unbiased proteomic screen, we identify protein kinase beta as a new endoxifen drug target, resulting in suppression of AKT signaling and apoptosis
