Abstract:
Cancer progression depends on stepwise accumulation of oncogenic mutations and a select group of growth factors essential for tumor growth, metastasis and angiogenesis. Agents blocking the epidermal growth factor receptor (EGFR, also called HER1 and ERBB1) and the co-receptor called HER2/ERBB2 have been approved over the last decade as anti-cancer drugs. Because the catalytically defective member of the family, HER3/ERBB3, plays critical roles in emergence of resistance of carcinomas to various drugs, current efforts focus on antibodies and other anti-HER3/ERBB3 agents, which we review herein with an emphasis on drug combinations and some unique biochemical features of HER3/ERBB3.
Insights
The epidermal growth factor receptor (EGFR) family is crucial in cancer. Targeting HER3/ERBB3, a key player in drug resistance, shows promise for new anti-cancer therapies, especially in combination treatments.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Cancer progression involves oncogenic mutations and growth factors driving tumor growth, metastasis, and angiogenesis.
- Approved anti-cancer drugs target the epidermal growth factor receptor (EGFR) and HER2/ERBB2.
- The HER3/ERBB3 receptor is implicated in carcinoma resistance to various anti-cancer drugs.
Purpose of the Study:
- To review current efforts and emerging strategies targeting the HER3/ERBB3 receptor.
- To highlight the role of HER3/ERBB3 in drug resistance.
- To emphasize drug combinations and unique biochemical features of HER3/ERBB3.
Main Methods:
- Literature review of existing research on HER3/ERBB3.
- Analysis of biochemical properties of HER3/ERBB3.
- Examination of anti-HER3/ERBB3 agents and drug combinations.
Main Results:
- HER3/ERBB3 plays a critical role in the development of drug resistance in carcinomas.
- Emerging anti-HER3/ERBB3 agents, including antibodies, are under investigation.
- Drug combinations involving anti-HER3/ERBB3 agents show potential for overcoming resistance.
Conclusions:
- Targeting HER3/ERBB3 is a promising strategy to overcome cancer drug resistance.
- Further research into anti-HER3/ERBB3 agents and their combinations is warranted.
- Understanding the unique biochemical aspects of HER3/ERBB3 is crucial for developing effective therapies.
