Involvement of novel PKCs (nPKCs) in the negative regulation of insulin-signaling pathway is a current interest of many workers investigating the cause for insulin resistance and type 2 diabetes. Free fatty acids (FFAs) are recently shown to be the major players in inducing insulin resistance in insulin target cells. They are also found to be involved in(More)
Free fatty acids are known to play a key role in promoting loss of insulin sensitivity,thereby causing insulin resistance and type 2 diabetes.However,the underlying mechanism involved is still unclear.In searching for the cause of the mechanism,it has been found that palmitate inhibits insulin receptor (IR)gene expression,leading to a reduced amount of IR(More)
Fatty acids are known to play a key role in promoting the loss of insulin sensitivity causing insulin resistance and type 2 diabetes. However, underlying mechanism involved here is still unclear. Incubation of rat skeletal muscle cells with palmitate followed by I(125)- insulin binding to the plasma membrane receptor preparation demonstrated a two-fold(More)
It is known that free fatty acid (FFA) contributes to the development of insulin resistance and type2 diabetes. However, the underlying mechanism in FFA-induced insulin resistance is still unclear. In the present investigation we have demonstrated that palmitate significantly (p <0.001) inhibited insulin-stimulated phosphorylation of PDK1, the key insulin(More)
