16364465
|
Rottlerin inhibited amylase secretion stimulated by both PKC-dependent pathways (CCK, bombesin, carbachol, TPA) and also by PKC-independent pathways (secretin, VIP, cAMP analogue).
|

Unsaturated fatty acids phosphorylate and destabilize ABCA1 through a protein kinase C delta pathway.
|
56 |
17325386
|
We previously reported that unsaturated fatty acids destabilize ABCA1 in murine macrophages and ABCA1-transfected baby hamster kidney cells by increasing its serine phosphorylation through a phospholipase D (PLD) pathway.
|
57 |
17325386
|
The protein kinase C delta (PKCdelta)-specific inhibitor rottlerin and PKCdelta small interfering RNA completely abolished the ability of unsaturated fatty acids to inhibit lipid transport activity, to reduce protein levels, and to increase serine phosphorylation of ABCA1, implicating a role for PKCdelta in the ABCA1-destabilizing effects of fatty acids.

In isolated islets, 50 microM CPZ decreased IRS2 expression by promoting ubiquitin-proteasome degradation, which had been prevented by proteasome inhibitors.
|
62 |
18308779
|
Furthermore, similar to the effect of HCPZ treatment, a high dosage of rottlerin, a protein kinase C-delta inhibitor, reduced IRS2 levels in the islets.

Aldose reductase regulates high glucose-induced ectodomain shedding of tumor necrosis factor (TNF)-alpha via protein kinase C-delta and TNF-alpha converting enzyme in vascular smooth muscle cells.
|
65 |
18772236
|
This decrease in unprocessed TNF-alpha was prevented by the aldose reductase (AR) inhibitor sorbinil and AR small interference RNA.
|
66 |
18772236
|
Treatment with HG, but not equimolar mannitol or 3-O-methyl glucose, resulted in phosphorylation and activation of TNF-alpha converting enzyme (TACE) (ADAM17), which were attenuated by sorbinil or AR-specific small interference RNA.
|
67 |
18772236
|
HG-induced TACE phosphorylation and TNF-alpha processing were also prevented by TNF-alpha protease inhibitor-1, an inhibitor of TACE.
|
68 |
18772236
|
Inhibition of protein kinase C (PKC)-delta by rottlerin prevented HG-induced TACE activation and the accumulation of unprocessed TNF-alpha.
|
69 |
18772236
|
Sorbinil treatment also decreased the expression of TNF-alpha, matrix metalloproteinase-2, matrix metalloproteinase-9, and increased tissue inhibitor of metalloproteinase-3 in vascular smooth muscle cells treated with HG and in balloon-injured carotid arteries of diabetic rats.
|
70 |
18772236
|
These results indicate that HG-induced TNF-alpha shedding could be attributed to TACE activation, which is regulated, in part, by PKC-delta and AR.
|
71 |
18772236
|
Therefore, inhibition of TACE by TNF-alpha protease inhibitor-1, or pharmacological inhibition of PKC-delta or AR may represent useful strategies for treating vascular inflammation associated with diabetes.

We tested the hypothesis that 17beta-estradiol (E(2)) has dual effects on the heart, increasing levels of proteins thought to have beneficial cardiovascular effects (e.g. endothelial nitric oxide (NO) synthase (eNOS)) as well as those thought to have detrimental cardiovascular effects (e.g. type 1 angiotensin II (AngII) receptor (AT(1)R)).

Ovariectomized Wistar rats consuming a high-sodium diet received one of four treatments (n=7 per group): group 1, placebo pellets; group 2, E(2) (0 x 5 mg/pellet, 21-day release); group 3, NOS inhibitor, N(omega)-nitro-L-arginine-methyl-ester (L-NAME; 40 mg/kg per day for 14 days) plus Ang II (0 x 225 mg/kg per day on days 11-14); group 4, E(2) plus L-NAME/Ang II.
|
74 |
18931023
|
E(2) increased cardiac levels of estrogen receptors ESR1 and ESR2, an ESR-associated membrane protein caveolin-3, eNOS, and phosphorylated (p)eNOS, thus, exerting potentially beneficial cardiovascular effects on NO.
|
75 |
18931023
|
However, E(2) also increased cardiac levels of proteins associated with cardiovascular injury and inflammation including, AT(1)R, protein kinase C delta (PRKCD), phosphorylated PRKC, and phosphorylated extracellular signal regulated kinase (pMAPK)3/1, plasminogen activator inhibitor-1 (PAI-1), osteopontin and ED-1, a monocyte/macrophage-specific protein.
|
76 |
18931023
|
E(2) treatment led to similar protein changes in the hearts of L-NAME/Ang II-treated rats except that the increase in peNOS was prevented, and L-NAME/Ang II and E(2) had additive effects in increasing cardiac PRKCD and PAI-1.
|

|
In the retina, pericyte apoptosis and the formation of acellular capillaries, the most specific vascular pathologies attributed to hyperglycemia, is linked to the loss of platelet-derived growth factor (PDGF)-mediated survival actions owing to unknown mechanisms.
|
92 |
19881493
|
Here we show that hyperglycemia persistently activates protein kinase C-delta (PKC-delta, encoded by Prkcd) and p38alpha mitogen-activated protein kinase (MAPK) to increase the expression of a previously unknown target of PKC-delta signaling, Src homology-2 domain-containing phosphatase-1 (SHP-1), a protein tyrosine phosphatase.
|
93 |
19881493
|
This signaling cascade leads to PDGF receptor-beta dephosphorylation and a reduction in downstream signaling from this receptor, resulting in pericyte apoptosis independently of nuclear factor-kappaB (NF-kappaB) signaling.
|
94 |
19881493
|
Unlike diabetic age-matched wild-type mice, diabetic Prkcd(-/-) mice did not show activation of p38alpha MAPK or SHP-1, inhibition of PDGF signaling in vascular cells or the presence of acellular capillaries.

Protein kinase C delta contributes to increase in EP3 agonist-induced contraction in mesenteric arteries from type 2 diabetic Goto-Kakizaki rats.

22371141
|
Here, we investigated the vasoconstrictor effects of PGE(2) and of sulprostone (EP1-/EP3-receptor agonist) in rings cut from superior mesenteric arteries isolated from GK rats (37-44 weeks old).
|
105 |
22371141
|
In arteries from GK rats (vs. those from age-matched Wistar rats), examined in the presence of a nitric oxide synthase inhibitor: 1) the PGE(2)- and sulprostone-induced vasocontractions (which were not blocked by the selective EP1 receptor antagonist sc19220) were enhanced, and these enhancements were suppressed by rottlerin (selective PKCδ inhibitor) but not by Gö6976 (selective PKCα/β inhibitor); 2) the sulprostone-stimulated phosphorylation of PKCδ (at Thr(505)), which yields an active form, was increased and 3) sulprostone-stimulated caldesmon phosphorylations, which are related to isometric force generation in smooth muscle, were increased.

This study characterizes the effect of glucose-induced activation of protein kinase Cδ (PKCδ) and Src homology-2 domain-containing phosphatase-1 (SHP-1) expression on vascular endothelial growth factor (VEGF) actions in glomerular podocytes in cultures and in glomeruli of diabetic rodents.
|
108 |
22499584
|
Elevation of glucose levels induced PKCδ and p38 mitogen-activated protein kinase (p38 MAPK) to increase SHP-1 expression, increased podocyte apoptosis, and inhibited VEGF activation in podocytes and glomerular endothelial cells.
|
109 |
22499584
|
Increased PKCδ activation and SHP-1 expression correlated with loss of VEGF signaling and podocyte numbers in the glomeruli of diabetic rats and mice.
|
110 |

|
In contrast, diabetic PKCδ-knockout (Prkcd(-/-)) mice did not exhibit activation of p38 MAPK and SHP-1 or inhibition of VEGF signaling in renal glomeruli.
