TAK1 regulates multiple protein kinase cascades activated by bacterial lipopolysaccharide.

abstract：:This report focuses on the modulatory role of endogenous H(2)O(2) on lipopolysaccharide (LPS)/interferon-gamma (IFN-gamma)-induced inducible nitric oxide synthase (NOS2) gene expression in rat peritoneal macrophages. Exogenously added H(2)O(2) was initially found to inhibit the synthesis of NOS2, which prompted us to ...
