The Ambivalent Function of YAP in Apoptosis and Cancer

Area of Science:

• Oncology
• Molecular Biology
• Cell Biology

Background:

• Yes-associated protein (YAP) is a key regulator of the Hippo-YAP signaling pathway.
• YAP is recognized for its role in inhibiting apoptosis, making it a potential anti-cancer target.
• Emerging evidence indicates YAP also contributes to p73-mediated apoptosis, complicating its therapeutic utility.

Purpose of the Study:

• To evaluate the clinical relevance of YAP in cancer pathophysiology.
• To summarize regulators of the Hippo-YAP pathway and their impact on apoptosis.
• To identify future research directions for targeting the Hippo-YAP pathway in cancer therapy.

Main Methods:

• Literature review and synthesis of existing studies on YAP and apoptosis.
• Analysis of molecules, processes, and drugs affecting the Hippo-YAP signaling pathway.
• Discussion of the implications for cancer treatment strategies.

Main Results:

• YAP's role in apoptosis is context-dependent, exhibiting both pro- and anti-apoptotic functions.
• The Hippo-YAP pathway's regulation involves complex molecular interactions affecting cell death.
• Targeting YAP for cancer therapy requires careful consideration of its dual apoptotic roles.

Conclusions:

• The clinical utility of YAP as a universal anti-cancer target is questionable due to its complex role in apoptosis.
• Further research is needed to elucidate the precise mechanisms of YAP in different cancer types.
• Defining specific conditions for targeting the Hippo-YAP pathway is crucial for successful clinical trials.
