(A) Body weight, (B) Liver weight, and (C) Liver/body weight ratio in livers of wild-type mice subjected to partial hepatectomy (PH). (D) Relative hepatic mRNA expression of Itpr2, c-Jun, and c-Fos at pre-hepatectomy, 1-hour, and 2-hours after PH. *p < 0.01, compared with pre-hepatectomy (n = 4-5 mice).
