Nuclear ErbB-2: a Novel Therapeutic Target in ErbB-2-Positive Breast Cancer?
Membrane overexpression of ErbB-2 (MErbB-2), a member of the ErbB family of receptor tyrosine kinases, occurs in 15-20% of breast cancers (BC) and constitutes a therapeutic target in this BC subtype (ErbB-2-positive). Although MErbB-2-targeted therapies have significantly improved patients' clinical outcome, resistance to available drugs is still a major issue in the clinic. Lack of accurate biomarkers for predicting responses to anti-ErbB-2 drugs at the time of diagnosis is also an important unresolved issue. Hence, a better understanding of the ErbB-2 signaling pathway constitutes a critical task in the battle against BC. In its canonical mechanism of action, MErbB-2 activates downstream signaling pathways, which transduce its proliferative effects in BC. The dogma of ErbB-2 mechanism of action has been challenged by the demonstration that MErbB-2 migrates to the nucleus, where it acts as a transcriptional regulator. Accumulating findings demonstrate that nuclear ErbB-2 (NErbB-2) is involved in BC growth and metastasis. Emerging evidence also reveal a role of NErbB-2 in the response to available anti-MErbB-2 agents. Here, we will review NErbB-2 function in BC and will particularly discuss the role of NErbB-2 as a novel target for therapy in ErbB-2-positive BC.
期刊介绍:
Hormones and Cancer is a unique multidisciplinary translational journal featuring basic science, pre-clinical, epidemiological, and clinical research papers. It covers all aspects of the interface of Endocrinology and Oncology. Thus, the journal covers two main areas of research: Endocrine tumors (benign & malignant tumors of hormone secreting endocrine organs) and the effects of hormones on any type of tumor. We welcome all types of studies related to these fields, but our particular attention is on translational aspects of research. In addition to basic, pre-clinical, and epidemiological studies, we encourage submission of clinical studies including those that comprise small series of tumors in rare endocrine neoplasias and/or negative or confirmatory results provided that they significantly enhance our understanding of endocrine aspects of oncology. The journal does not publish case studies.
