We have recently shown that the reduction in insulin sensitivity of rats fed a high-fat diet is associated with the translocation of the novel protein kinase Cε(nPKCε) from cytosolic to particulate fractions in red skeletal muscle and also the downregulation of cytosolic nPKCθ. Here we have further investigated the link between insulin resistance and PKC by assessing the effects of the thiazolidinedione insulin-sensitizer BRL-49653 on PKC isoenzymes in muscle. BRL-49653 increased the recovery of nPKC isoenzymes in cytosolic fractions of red muscle from fat-fed rats, reducing their apparent activation and/or downregulation, whereas PKC in control rats was unaffected. Because BRL-49653 also improves insulin-stimulated glucose uptake in fat-fed rats and reduces muscle lipid storage, especially diglyceride content, these results strengthen the association between lipid availability, nPKC activation, and skeletal muscle insulin resistance and support the hypothesis that chronic activation of nPKC isoenzymes is involved in the generation of muscle insulin resistance in fat-fed rats.

2-Palmitamidoethyl ester of adenosine 5'-phosphate (PEA-AMP) stimulates the rabbit skeletal muscle protein kinase in relatively narrow range of high drug concentration. Mechanism of this effect seems to be analogous to that of cyclic AMP.

Hydroxy Compounds

The inhibitory effects of adenosine 5'-phosphate esters with lipoid hydroxy compounds on rabbit skeletal muscle protein kinase are in comparison with adenosine or adenosine 5'-monophosphate relatively weak. The inhibitory effect is in some cases preceded by the enzyme stimulation which can reach up to 70-80% of the stimulation by cyclic AMP. While the inhibitory effect seems to be caused by the adenosine moiety of the compound, the nature of the stimulatory effect is not yet elucidated.
