AR and YAP crosstalk: impacts on therapeutic strategies in prostate cancer

Area of Science:

• Oncology
• Molecular Biology
• Cell Signaling

Background:

• Prostate cancer is a common malignancy in men, with the androgen receptor (AR) pathway central to its development.
• Current anti-androgen therapies are often ineffective against castration-resistant prostate cancer (CRPC).
• The Hippo-YAP signaling pathway is increasingly implicated in prostate cancer, showing crosstalk with the AR pathway.

Purpose of the Study:

• To review the molecular mechanisms underlying the interaction between the AR and Hippo-YAP signaling pathways in prostate cancer.
• To elucidate the roles of AR and YAP in prostate cancer initiation, progression, and treatment resistance.
• To discuss the therapeutic potential of targeting the YAP pathway in prostate cancer.

Main Methods:

• Literature review of studies investigating AR and YAP signaling in prostate cancer.
• Analysis of molecular mechanisms of AR-YAP crosstalk, including transcriptional, translational, and post-translational regulation.
• Examination of preclinical and clinical data on YAP's role in prostate cancer.

Main Results:

• AR influences YAP stability and function through transcriptional, translational, and phosphorylation regulation.
• YAP exhibits dual regulatory effects on AR, promoting or inhibiting its activity.
• The AR-YAP axis is significantly involved in prostate cancer development, progression, and resistance to therapy.

Conclusions:

• The intricate crosstalk between AR and YAP is crucial in prostate cancer pathogenesis.
• Targeting the YAP pathway presents a promising therapeutic strategy for overcoming treatment resistance in prostate cancer.
• Further research into the AR-YAP interaction may yield novel clinical applications.
