These results suggest that (a) insulin and phorbol esters similarly stimulate the translocation of each PKC isoform except for PKC-zeta, and (b) the translocation of both nPKCs and cPKCs occurs during insulin and TPA actions in rat adipocytes.

Under euglycemic and hyperglycemic conditions, basal and insulin-stimulated action on phosphatidylinositol (PI) 3-kinase, protein kinase B/Akt, and ERK were reduced in GK rats, whereas insulin-stimulated protein kinase C (PKC)zeta activity was not altered.

We have examined the basal and insulin-mediated phosphorylation of protein kinase B (PKB), protein kinase Czeta (PKCzeta), p70(S6k), mitogen-activated protein kinase (MAPK)/p90(rsk) pathway and the expression of IGFBP-3, -4, and -5 in mice selected for body weight gain (line C) and reduction (line L).

Not only insulin but also glucose and exercise can activate PKCzeta through diverse pathways.

We gave insulin intravenously to these rats and determined the association of glucose transporter-4 with plasma membranes, as well as the phosphorylation of phosphoinositide-dependent protein kinase-1 (PDK1), Akt, and PKCzeta.

In cells overexpressing PKC-zeta there was marked inhibition of insulin-stimulated PI3K activity associated with IRS-1, -3 and -4 but not IRS-2.

|
That is, PI3K activity associated with IRS-2 in response to insulin was similar in control cells and cells overexpressing PKC-zeta.

|
We conclude that IRS-3 and -4 are novel substrates for PKC-zeta that may participate in a negative feedback pathway for insulin signaling similar to IRS-1.

We have used different PKCzeta mutant constructs or the PP2A inhibitor, okadaic acid (OKA), to selectively inhibit PKCzeta- and PP2A-dependent pathways in cells expressing different caveolin-1 levels and evaluated the impact of insulin and ceramide on PKB/Akt activity in different PM subdomains.
