Popis: Tumor necrosis factor (TNF) plays a central role in the state of insulin resistance leading to type II diabetes. We here describe the crosstalk of TNF with insulin signaling cascades in the mouse muscle cell line pmi28. TNF downregulated insulin induced insulin receptor kinase activity and insulin induced activation of the transcription factor STAT5. Our results provide evidence that the inhibitory crosstalk between TNF and insulin in skeletal muscle cells comprises an interference with the expression of STAT5 regulated genes which may play an important role in the manifestation and/or progression of insulin resistance in muscle cells.
