Accelerated response of hepatic DNA synthesis to partial hepatectomy in rats pretreated with growth hormone or surgical stress.
نویسندگان
چکیده
The rise in hepatic DNA synthesis in response to partial hepatectomy was accelerated in rats subjected to surgery 4.5 to 8 hr or 3 days before hepatectomy. Bovine growth hor mone, in doses from 0.03 to 2.0 mg, also accelerated the response to hepatectomy, but cortisone, hydrocortisone, and adrenocorticotropic hormone were ineffective. Neither surgery nor growth hormone stimulated DNA synthesis significantly in the livers of nonhepatectomized rats.

متن کاملEffect of cyclosporine a on hepatic compensatory growth: role of calcium status.
Cyclosporine A (CsA) has been reported to positively influence hepatic compensatory growth (HCG) in normal animals. The role of calcium in the CsA-mediated influence on HCG was studied in normal and in chronically hypocalcemic rats, a model in which HCG is perturbed. CsA (3.33 mg/kg/day for 10 days) was administered before 2/3 partial hepatectomy (PHx). CsA did not influence serum Ca(2+) but si...
متن کاملTransforming Growth Factor-a (TGF-a) Improves Hepatic DNA Synthesis after Hepatectomy in Cirrhotic Rats’?*
Impaired liver regeneration in cirrhosis complicates the surgical treatment of liver tumors which arise in this setting. We developed a rat model to investigate the regenerative response of cirrhotic liver after hepatectomy and studied the effect of exogenous transforming growth factor-a (TGF-a), a potent liver mitogen. Micronodular cirrhosis was established by the simultaneous administration o...
متن کاملTiming of hepatocyte entry into DNA synthesis after partial hepatectomy is cell autonomous.
After surgical removal of two-thirds of the liver, remaining hepatocytes replicate and restore hepatic mass within 2 weeks. This process must be initiated by signals extrinsic to the hepatocyte, but it remains unclear whether subsequent events leading to DNA synthesis (S phase) are regulated by circulating or locally produced growth factors (a noncell autonomous response), or by a program intri...

In male rats, hepatic glyoxalase activity and reduced glutathione, the cofactor for this enzyme system, approximately double 12 hr after partial (2/3) or sham hepatectomy, in which the liver lobes were handled during the sham operation. These changes precede by 10 to 12 hr the anticipated DNA synthesis after partial hepatectomy and by about 24 hr the smaller, but prolonged, DNA synthesis that o...
