Rho Kinases in Embryonic Development and Stem Cell Research.

Area of Science:

• Molecular Biology
• Cell Biology
• Biochemistry

Background:

• Rho-associated coiled-coil containing kinases (ROCKs) are serine/threonine kinases downstream of RhoA, regulating the actin cytoskeleton.
• ROCK signaling is implicated in diverse cellular processes including contraction, migration, and proliferation.
• ROCKs are increasingly linked to clinical conditions such as cardiovascular diseases, immune disorders, and cancer.

Purpose of the Study:

• To provide an overview of milestone discoveries in ROCK research.
• To focus on the current understanding of ROCK signaling in embryonic development.
• To review the current research status using knockout/knockin mouse models and stem cell research.

Main Methods:

• Review of existing literature on ROCK signaling.
• Analysis of data from gene targeting and RNA interference studies.
• Inclusion of insights from novel biotechnologies like CRISPR-Cas and single-cell omics.

Main Results:

• ROCK1 and ROCK2, previously assumed redundant, exhibit overlapping and distinct cellular, physiological, and pathophysiological roles.
• ROCK signaling is a versatile modulator of fundamental cell behaviors.
• Advances in technology have accelerated ROCK research and its clinical relevance.

Conclusions:

• ROCK signaling is critical in embryonic development, with distinct isoform functions emerging.
• Knockout/knockin mouse models and stem cell research are key to dissecting ROCK isoform-specific roles.
• Understanding ROCKs offers therapeutic potential for various diseases.
