Receptor tyrosine kinases and cancer: oncogenic mechanisms and therapeutic approaches
ONCOGENE(2021)
Abstract
Receptor tyrosine kinases (RTKs) are transmembrane receptors of great clinical interest due to their role in disease, notably cancer. Since their discovery, several mechanisms of RTK dysregulation have been identified, resulting in multiple cancer types displaying ‘oncogenic addiction’ to RTKs. As a result, RTKs have represented a major class for targeted therapeutics over the past two decades, with numerous small molecule-based tyrosine kinase inhibitor (TKI) therapeutics having been developed and clinically approved for several cancers. However, many of the current RTK inhibitor treatments eventually result in the rapid development of acquired resistance and subsequent tumor relapse. Recent technological advances and tools are being generated for the identification of novel RTK small molecule therapeutics. These newer technologies will be important for the identification of diverse types of RTK inhibitors, targeting both the receptors themselves as well as key cellular factors that play important roles in the RTK signaling cascade.
