Glycogenolysis in liver of phosphorylase kinase-deficient rats during liver perfusion and ischaemia.
Liver glycogen degradation and phosphorylase activity were measured in normal and phosphorylase kinase-deficient (gsd/gsd) rats. During perfusion or ischaemia, gsd/gsd-rat livers showed a brisk glycogenolysis. There was also a small (1.9-fold) but significant transient increase in their phosphorylase alpha activity during ischaemia, despite their phosphorylase b kinase deficiency; it seems unlikely, however, that this was the main determinant of the glycogenolysis.
