Titolo:  Studies on the kinetics of expression of cell cycle dependent proto-oncogenes during mitogen-induced liver cell proliferation
Data di pubblicazione:  1989
Abstract:  The present study was undertaken to determine the kinetics of DNA synthesis and expression of cell cycle dependent proto-oncogenes in response to two types of cell proliferative stimuli in male Wistar rat liver. The peak of DNA synthesis was approximately 24 h after a compensatory cell proliferative stimulus induced by 2/3 partial hepatectomy and approximately 36 h following a mitogenic stimulus obtained with a single dose of lead nitrate (10 micromol/100 g body wt, through femoral vein). Even though both proliferative stimuli induced the expression of c-fos, c-myc and c-Ha-ras, the extent of the increase in c-fos expression was 4- to 5-fold less in mitogen-induced cell proliferation. In addition, while the expression of c-myc, following partial hepatectomy returned to basal level by 4 h, the induced expression of c-myc persisted for up to 40 h during the lead nitrate-induced liver cell proliferation.
