Hepatocyte Rho-associated kinase signaling is required for mice to survive experimental porphyria-associated liver injury.

ABSTRACT:

Background

Rho-associated kinases 1 and 2 (ROCK1 and ROCK2) regulate critical cell functions, including actomyosin contractility, apoptosis, and proliferation. Some studies suggest that ROCK inhibition may serve as a treatment for liver fibrosis. More investigation is needed to understand the role of hepatocyte ROCK signaling in vivo, especially in the context of profibrotic liver injury.

Methods

Rock1fl/fl, Rock2fl/fl, and Rock1fl/fl; Rock2fl/fl mice were given adeno-associated virus serotype 8 (AAV8)-thyroid hormone-binding globulin (TBG)-Cre to produce targeted gene deletion in hepatocytes, or given AAV8-TBG-Null to generate littermate controls (WT). Mice were then placed on a 0.1% 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet to induce liver injury.
