| Abstract: | Disturbed cellular calcium homeostasis has been observed during CCl4 poisoning, with an increase in calcium content 1 h after administration. Intracellular increase of calcium may be expected to alter membrane/cytosol distribution of calmodulin (CaM). This paper investigates changes in rat liver subcellular CaM distribution 30 min, 1 h and 2 h after CCl4 intoxication. The whole liver value remained unchanged, whereas the nuclear fraction increased and the microsomal and cytosolic fraction decreased. This may suggest that CaM is involved in the several liver cell alterations caused by CCl4 poisoning. |
