Abstract:
Src family kinases (SFKs) are non-receptor tyrosine kinases that are recognized as proto-oncogenic products. Among SFKs, YES1 is frequently amplified and overexpressed in a variety of human tumors, including lung, breast, ovarian, and skin cancers. YES1 plays a pivotal role in promoting cell proliferation, survival, and invasiveness during tumor development. Recent findings indicate that YES1 expression and activation are associated with resistance to chemotherapeutic drugs and tyrosine kinase inhibitors in human malignancies. YES1 undergoes post-translational modifications, such as lipidation and nitrosylation, which can modulate its catalytic activity, subcellular localization, and binding affinity for substrate proteins. Therefore, we investigated the diverse mechanisms governing YES1 activation and its impact on critical intracellular signal transduction pathways. We emphasized the function of YES1 as a potential mechanism contributing to the anticancer drug resistance emergence.
Insights
Src family kinases (SFKs), particularly YES1, are key drivers in various cancers. This study explores how YES1 activation contributes to anticancer drug resistance, offering insights into novel therapeutic strategies.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Src family kinases (SFKs) are proto-oncogenic non-receptor tyrosine kinases.
- YES1, an SFK, is amplified and overexpressed in numerous human cancers, promoting tumor growth and invasiveness.
- YES1 activation is linked to therapeutic resistance in malignancies.
Purpose of the Study:
- To investigate the mechanisms regulating YES1 activation.
