Tissue Repair in the Mouse Liver Following Acute Carbon Tetrachloride Depends on Injury‐Induced Wnt/β‐Catenin Signaling
Ludan Zhao, Yinhua Jin, Katie Donahue, Margaret Tsui, Matt Fish, Catriona Y. Logan, Bruce Wang, Roel Nusse – 14 February 2019 – In the liver, Wnt/β‐catenin signaling is involved in regulating zonation and hepatocyte proliferation during homeostasis. We examined Wnt gene expression and signaling after injury, and we show by in situ hybridization that Wnts are activated by acute carbon tetrachloride (CCl4) toxicity. Following injury, peri‐injury hepatocytes become Wnt‐responsive, expressing the Wnt target gene axis inhibition protein 2 (Axin2).
