The Hippo pathway: Organ size control and beyond.

Area of Science:

• Cell Biology
• Molecular Biology
• Biochemistry

Background:

• The Hippo signaling pathway is a conserved regulator of organ size, tissue homeostasis, and regeneration.
• It integrates diverse signals to control YAP/TAZ transcriptional coactivators.
• Pathway regulation involves spatial organization at the plasma membrane and biomolecular condensation.

Purpose of the Study:

• To review the regulatory mechanisms of the Hippo signaling pathway.
• To highlight the role of spatial organization and biomolecular condensation in Hippo signaling.
• To discuss the implications of Hippo pathway dysregulation in cancer and regenerative medicine.

Main Methods:

• Literature review of recent studies on the Hippo signaling pathway.
• Analysis of molecular mechanisms controlling pathway activity.
• Discussion of therapeutic strategies targeting the Hippo pathway.

Main Results:

• The Hippo pathway's spatial organization at the plasma membrane is critical for its precise control.
• Biomolecular condensation adds complexity to Hippo signaling regulation.
• Dysregulation of the Hippo pathway, particularly YAP/TAZ activity, is linked to cancer and impacts drug resistance.

Conclusions:

• Understanding Hippo pathway regulation provides insights into organ size control and tissue repair.
• Targeting the Hippo pathway offers therapeutic potential for cancer treatment and regenerative medicine.
• Small molecule inhibitors targeting YAP-TEAD interactions represent a promising therapeutic avenue.
