Abstract:
In recent years, tyrosine kinases (TKs) have been recognized as central players and regulators of cancer cell proliferation, apoptosis, and angiogenesis, and are therefore considered suitable potential targets for anti-cancer therapies. Several strategies for targeting TKs have been developed, the most successful being monoclonal antibodies and small molecule tyrosine kinase inhibitors. However, increasing evidence of acquired resistance to these drugs has been documented, and extensive preclinical studies are ongoing to try to understand the molecular mechanisms by which cancer cells are able to bypass their inhibitory activity.This review intends to present the most recently identified molecular mechanisms that mediate acquired resistance to tyrosine kinase inhibitors, identified through the use of in vitro models or the analysis of patient samples. The knowledge obtained from these studies will help to design better therapies that prevent and overcome resistance to treatment in cancer patients.
Insights
Acquired resistance to tyrosine kinase inhibitors is a major challenge in cancer therapy. This review highlights recent molecular mechanisms driving this resistance, aiding in developing more effective anti-cancer treatments.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Tyrosine kinases (TKs) are crucial regulators of cancer cell growth and survival.
- Targeting TKs with therapies like monoclonal antibodies and small molecule inhibitors has shown success.
- Acquired resistance to these TK-targeting drugs is a significant clinical problem.
Purpose of the Study:
- To review the latest molecular mechanisms of acquired resistance to tyrosine kinase inhibitors.
- To provide insights for developing novel anti-cancer therapies that overcome drug resistance.
Main Methods:
- Review of recent preclinical studies.
- Analysis of in vitro models of cancer.
- Examination of patient samples to identify resistance mechanisms.
Main Results:
- Identified several recently discovered molecular mechanisms underlying acquired resistance to TKIs.
- Demonstrated that cancer cells develop diverse strategies to evade TKI activity.
Conclusions:
- Understanding these resistance mechanisms is vital for improving cancer treatment outcomes.
- Future therapies should aim to prevent or overcome acquired resistance to TKIs.
