How Hippo Signaling Pathway Modulates Cardiovascular Development and Diseases

Area of Science:

• Cardiovascular biology
• Molecular signaling pathways
• Oncology

Background:

• Cardiovascular diseases are a leading global cause of mortality, often involving irreversible cardiomyocyte loss.
• The Hippo-YAP pathway, a key regulator of organ size, is essential for normal heart development and function.
• Emerging evidence links Hippo signaling to various cardiovascular pathologies, including hypertrophy, angiogenesis, and cell death.

Purpose of the Study:

• To review the current understanding of the Hippo signaling pathway's role in cardiovascular disease.
• To explore how Hippo signaling modulates pathological processes in the cardiovascular system.
• To identify potential molecular therapeutic targets within the Hippo pathway for cardiovascular conditions.

Main Methods:

• Literature review of studies on Hippo signaling in cardiovascular contexts.
• Analysis of research on the Hippo-YAP cascade (MST1/2-SAV1-LATS1/2-MOB1-YAP/TAZ) and associated factors.
• Synthesis of findings related to Hippo pathway's influence on cardiac development, hypertrophy, angiogenesis, regeneration, apoptosis, and autophagy.

Main Results:

• The Hippo-YAP pathway plays a critical role in maintaining normal heart size and function.
• Inhibition of the Hippo pathway leads to YAP/TAZ accumulation and transcriptional activity, impacting cardiac cells.
• Hippo signaling is implicated in diverse cardiovascular disease processes, from development to cell death and regeneration.

Conclusions:

• The Hippo-YAP pathway is a significant regulator in cardiovascular health and disease.
• Understanding Hippo signaling mechanisms in the heart offers insights into disease pathogenesis.
• Targeting the Hippo pathway presents a promising avenue for novel cardiovascular therapeutics.
