Redundant Functions of ERK1 and ERK2 Maintain Mouse Liver Homeostasis Through Down‐Regulation of Bile Acid Synthesis
Francesca Cingolani, Yunshan Liu, Yang Shen, Jing Wen, Alton B. Farris, Mark J. Czaja – 21 December 2021 – Activation of extracellular signal–regulated kinase (ERK) 1/2 promotes hepatocyte proliferation in response to growth stimuli, but whether constitutive hepatocyte ERK1/2 signaling functions in liver physiology is unknown. To examine the role of ERK1/2 in hepatic homeostasis, the effects of a knockout of Erk1 and/or Erk2 in mouse liver were examined. The livers of mice with a global Erk1 knockout or a tamoxifen‐inducible, hepatocyte‐specific Erk2 knockout were normal.
