title: Hexokinase isozyme pattern in CCl(4)-injured rat liver.
abstract: Activities of hexokinase isozymes in carbon tetrachloride (CCl(4))-injured rat liver were determined quantitatively by DEAE-cellulose column chromatography and compared with those of regenerating liver, fetal liver and ascites hepatoma cells (AH 130). The CCl(4)-injured liver revealed an isozyme distribution with predominant Types I, II and III (3.2, 8.8 and 6.8 times higher than the control values, respectively) and with undetectable activity of Type IV hexokinase (glucokinase). Although the isozyme pattern generally resembled that of fetal liver or hepatoma cells, the relatively high activity of hexokinase Type III in CCl(4) treatment characterizes the pattern of hexokinase isozyme in acue liver damage.
