RPS6KA3 and biliary liver cirrhosis: Because the resulting activation of HSC and liver fibrosis is similar in any type of chronic liver injury, these results suggest that the inhibition of both RSK and its phosphorylation of C/EBPβ may be effective in preventing/regressing liver fibrosis in animal models that reflect other causes of human liver fibrosis, such as biliary cirrhosis, alcoholic liver disease, immune liver injury, and genetic iron overload [3].
