Abstract
Being a member of the EGFR tyrosine kinase family, HER3 has been shown to be overexpressed in a number of cancers, including breast cancer (BC). The kinase activity of HER3 is extremely low, and it forms heterodimers with partners, HER2 in particular, that promote biological processes like cell migration, survival, and proliferation by activating downstream carcinogenic signaling pathways. The overexpression of HER3 is also directly linked to tumor invasion, metastasis, and a poor prognosis. Despite the relatively low expression of HER3 compared to EGFR and HER2, a lot of targeted drugs are making their way into clinical trials and seem to have a bright further. This review aims to summarize the relationship between HER3 overexpression, mutations, and carcinogenicity and drug resistance, starting from the unique structure and kinase activity of HER3. Simultaneously, numerous approaches to HER3 targeted therapy are enumerated, and the clinical detection methods for HER3 that are commonly employed in pathology are sorted and contrasted to offer physicians a range of options. We think that a better knowledge of the mechanisms underlying HER3 in tumors and the advancement of targeted HER3 therapy will contribute to an improved prognosis for cancer patients and an increase in the efficacy of anticancer therapies.
期刊介绍:
Life Sciences is an international journal publishing articles that emphasize the molecular, cellular, and functional basis of therapy. The journal emphasizes the understanding of mechanism that is relevant to all aspects of human disease and translation to patients. All articles are rigorously reviewed.
The Journal favors publication of full-length papers where modern scientific technologies are used to explain molecular, cellular and physiological mechanisms. Articles that merely report observations are rarely accepted. Recommendations from the Declaration of Helsinki or NIH guidelines for care and use of laboratory animals must be adhered to. Articles should be written at a level accessible to readers who are non-specialists in the topic of the article themselves, but who are interested in the research. The Journal welcomes reviews on topics of wide interest to investigators in the life sciences. We particularly encourage submission of brief, focused reviews containing high-quality artwork and require the use of mechanistic summary diagrams.
