Abstract
Phosphorylation of endogenous phosphatidylinositol was transiently increased following partial hepatectomy but was suppressed during peak DNA synthesis. Formation of inositol trisphosphate was decreased while generation of diacylglycerol and its breakdown to phosphatidic acid was increased. In response to partial hepatectomy protein kinase C was activated due to translocation from cytosol to particulate fraction, but the membrane bound activity was decreased during regeneration. Alteration of certain parameters in the signal transduction pathway apparently facilitates cell proliferation.
