Abstract

Tumour necrosis factor (TNF) did not stimulate lipolysis in isolated rat adipocytes, though preincubation with TNF increased adrenaline-stimulated fatty acid release. Glycogenolysis, gluconeogenesis and ketogenesis in isolated rat hepatocytes were not influenced by TNF in short-term (30-60 min) incubations. TNF stimulated 14CO2 production from [U-14C]glucose in rat hemidiaphragm preparations, but lactate production and alanine release were not significantly altered. It is concluded that TNF does not regulate short-term metabolism in adipocytes, hepatocytes and muscle preparations in the manner of a catabolic hormone.
