Cancers, Vol. 15, Pages 4689: Estrogen Receptor Signaling in Breast Cancer Cancers doi: 10.3390/cancers15194689 Authors: Paulina Miziak Marzena Baran Ewa Błaszczak Alicja Przybyszewska-Podstawka Joanna Kałafut Jolanta Smok-Kalwat Magdalena Dmoszyńska-Graniczka Michał Kiełbus Andrzej Stepulak Estrogen receptor (ER) signaling is a critical regulator of cell proliferation, differentiation, and survival in breast cancer (BC) and other hormone-sensitive cancers. In this review, we explore the mechanism of ER-dependent downstream signaling in BC and the role of estrogens as growth factors necessary for cancer invasion and dissemination. The significance of the clinical implications of ER signaling in BC, including the potential of endocrine therapies that target estrogens’ synthesis and ER-dependent signal transmission, such as aromatase inhibitors or selective estrogen receptor modulators, is discussed. As a consequence, the challenges associated with the resistance to these therapies resulting from acquired ER mutations and potential strategies to overcome them are the critical point for the new treatment strategies’ development.
