Molecular basis and therapeutic implications of binary YAPOn/YAPOff cancer classes

Area of Science:

• Oncology
• Molecular Biology
• Genomics

Background:

• Traditional cancer classification relies on tissue of origin.
• Precision medicine necessitates classification by molecular features for improved patient outcomes.
• Current tumor stratification methods are evolving, with a need for better approaches.

Purpose of the Study:

• To explore novel methods for stratifying tumors into molecular classes.
• To investigate the potential of higher-order features of cancer behavior for therapeutic targeting.
• To review the YAPon and YAPoff cancer super-classes and their therapeutic implications.

Main Methods:

• Functional stratification of cancers into YAPon and YAPoff super-classes.
• Analysis of YAP and TAZ expression and function in different cancer types.
• Examination of underlying mechanisms for YAP/TAZ's opposite roles in cancer.

Main Results:

• Cancers can be functionally stratified into YAPon and YAPoff super-classes.
• YAP/TAZ proteins act as oncogenes in YAPon cancers and tumor suppressors in YAPoff cancers.
• These distinct super-classes exhibit unique therapeutic vulnerabilities.

Conclusions:

• Classifying cancers based on YAP/TAZ function offers a new paradigm for precision oncology.
• Understanding YAP/TAZ's dual role is crucial for developing targeted cancer therapies.
• The YAPon/YAPoff classification may lead to broadly applicable therapeutic strategies.
