1	21896669	Western blotting was used to quantify the expression and phosphorylation of insulin receptor, insulin receptor substrate 1, and Akt and of inflammatory mediators that modulate insulin signaling in a negative manner (IKK?, JNK, and inducible nitric oxide synthase).
2	11606564	During a yeast tri-hybrid assay, phosphorylation of Ser(307) by JNK1 disrupted the interaction between the catalytic domain of the insulin receptor and the PTB domain of IRS-1.
3	12417588	Activation of the c-Jun N-terminal kinase (JNK) by proinflammatory cytokines inhibits insulin signaling, at least in part, by stimulating phosphorylation of rat/mouse insulin receptor substrate 1 (Irs1) at Ser(307) (Ser(312) in human IRS1).
