title: Interleukin-6 stimulates gluconeogenesis in primary cultures of rat hepatocytes.
abstract: Tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and IL-1 have been shown to stimulate the synthesis of acute-phase proteins; however, few studies have examined the effect of these cytokines on gluconeogenesis. We investigated the effects of these cytokines on gluconeogenesis in primary cultures of rat hepatocytes. Incubation of hepatocytes for 24 hours with TNF-alpha or IL-1 alpha did not affect gluconeogenesis. Hepatocytes incubated with 100 pmol/L and 1 nmol/L IL-6 had a dose-dependent increase (P < .05) in gluconeogenesis (2.6 +/- 0.1 and 3.2 +/- 0.1 pmol/10(6) cells/min, respectively) as compared with controls (2.0 +/- 0.1).
