The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Up-regulation of the Pit-2 phosphate transporter/retrovirus receptor by protein kinase C epsilon. (1/857)

The membrane receptors for the gibbon ape leukemia retrovirus and the amphotropic murine retrovirus serve normal cellular functions as sodium-dependent phosphate transporters (Pit-1 and Pit-2, respectively). Our earlier studies established that activation of protein kinase C (PKC) by treatment of cells with phorbol 12-myristate 13-acetate (PMA) enhanced sodium-dependent phosphate (Na/Pi) uptake. Studies now have been carried out to determine which type of Na/Pi transporter (Pit-1 or Pit-2) is regulated by PKC and which PKC isotypes are involved in the up-regulation of Na/Pi uptake by the Na/Pi transporter/viral receptor. It was found that the activation of short term (2-min) Na/Pi uptake by PMA is abolished when cells are infected with amphotropic murine retrovirus (binds Pit-2 receptor) but not with gibbon ape leukemia retrovirus (binds Pit-1 receptor), indicating that Pit-2 is the form of Na/Pi transporter/viral receptor regulated by PKC. The PKC-mediated activation of Pit-2 was blocked by pretreating cells with the pan-PKC inhibitor bisindolylmaleimide but not with the conventional PKC isotype inhibitor Go 6976, suggesting that a novel PKC isotype is required to regulate Pit-2. Overexpression of PKCepsilon, but not of PKCalpha, -delta, or -zeta, was found to mimic the activation of Na/Pi uptake. To further establish that PKCepsilon is involved in the regulation of Pit-2, cells were treated with PKCepsilon-selective antisense oligonucleotides. Treatment with PKCepsilon antisense oligonucleotides decreased the PMA-induced activation of Na/Pi uptake. These results indicate that PMA-induced stimulation of Na/Pi uptake by Pit-2 is specifically mediated through activation of PKCepsilon.  (+info)

The pleckstrin homology domain of protein kinase D interacts preferentially with the eta isoform of protein kinase C. (2/857)

The results presented here demonstrate that protein kinase D (PKD) and PKCeta transiently coexpressed in COS-7 cells form complexes that can be immunoprecipitated from cell lysates using specific antisera to PKD or PKCeta. The presence of PKCeta in PKD immune complexes was initially detected by in vitro kinase assays which reveal the presence of an 80-kDa phosphorylated band in addition to the 110-kDa band corresponding to autophosphorylated PKD. The association between PKD and PKCeta was further verified by Western blot analysis and peptide phosphorylation assays that exploited the distinct substrate specificity between PKCs and PKD. By the same criteria, PKD formed complexes only very weakly with PKCepsilon, and did not bind PKCzeta. When PKCeta was coexpressed with PKD mutants containing either complete or partial deletions of the PH domain, both PKCeta immunoreactivity and PKC activity in PKD immunoprecipitates were sharply reduced. In contrast, deletion of an amino-terminal portion of the molecule, either cysteine-rich region, or the entire cysteine-rich domain did not interfere with the association of PKD with PKCeta. Furthermore, a glutathione S-transferase-PKDPH fusion protein bound preferentially to PKCeta. These results indicate that the PKD PH domain can discriminate between closely related structures of a single enzyme family, e.g. novel PKCs epsilon and eta, thereby revealing a previously undetected degree of specificity among protein-protein interactions mediated by PH domains.  (+info)

PKC-dependent activation of p44/p42 MAPKs during myocardial ischemia-reperfusion in conscious rabbits. (3/857)

Using conscious rabbits, we examined the effect of ischemic preconditioning (PC) on p44 and p42 mitogen-activated protein kinases (MAPKs). We found that both isoforms contribute significantly to total MAPK activity in the heart (in-gel kinase assay: p44, 59 +/- 1%; p42, 41 +/- 1%). Ischemic PC (6 cycles of 4-min occlusion/4-min reperfusion) elicited a pronounced increase in total cellular MAPK activity (+89%). This increase, which occurred exclusively in the nuclear fraction, was contributed by both isoforms (in-gel kinase assay: p44, +97%; p42, +210%) and was accompanied by migration of the two proteins from the cytosolic to the nuclear compartment. In control rabbits, MAPK kinase (MEK)1 and MEK2, direct activators of p44 and p42 MAPKs, were located almost exclusively in the cytosolic fraction. Ischemic PC induced a marked increase in cytosolic MEK activity (+164%), whereas nuclear MEK activity did not change, indicating that MEK-induced activation of MAPKs occurred in the cytosolic compartment. Activation of MAPKs after ischemic PC was completely blocked by the protein kinase C (PKC) inhibitor chelerythrine. Selective overexpression of PKC-epsilon in adult rabbit cardiomyocytes induced activation of both p44 and p42 MAPKs and reduced lactate dehydrogenase release during simulated ischemia-reperfusion, which was abolished by the MEK inhibitor PD-98059. The results demonstrate that 1) ischemic PC induces a rapid activation of p44 and p42 MAPKs in hearts of conscious rabbits; 2) the mechanism of this phenomenon involves activation of p44 and p42 MAPKs in the cytosol and their subsequent translocation to the nucleus; and 3) it occurs via a PKC-mediated signaling pathway. The in vitro data implicate PKC-epsilon as the specific isoform responsible for PKC-induced MAPK activation and suggest that p44/p42 MAPKs contribute to PKC-epsilon-mediated protection against simulated ischemia. The results are compatible with the hypothesis that p44 and p42 MAPKs may play a role in myocardial adaptations to ischemic stress.  (+info)

PKCepsilon, via its regulatory domain and independently of its catalytic domain, induces neurite-like processes in neuroblastoma cells. (4/857)

To investigate the role of protein kinase C (PKC) isoforms in regulation of neurite outgrowth, PKCalpha, betaII, delta, and epsilon fused to enhanced green fluorescent protein (EGFP) were transiently overexpressed in neuroblastoma cells. Overexpression of PKCepsilon-EGFP induced cell processes whereas the other isoforms did not. The effect of PKCepsilon-EGFP was not suppressed by the PKC inhibitor GF109203X. Instead, process formation was more pronounced when the regulatory domain was introduced. Overexpression of various fragments from PKCepsilon regulatory domain revealed that a region encompassing the pseudosubstrate, the two C1 domains, and parts of the V3 region were necessary and sufficient for induction of processes. By deleting the second C1 domain from this construct, a dominant-negative protein was generated which suppressed processes induced by full-length PKCepsilon and neurites induced during retinoic acid- and growth factor-induced differentiation. As with neurites in differentiated neuroblastoma cells, processes induced by the PKCepsilon- PSC1V3 protein contained alpha-tubulin, neurofilament-160, and F-actin, but the PKCepsilon-PSC1V3-induced processes lacked the synaptic markers synaptophysin and neuropeptide Y. These data suggest that PKCepsilon, through its regulatory domain, can induce immature neurite-like processes via a mechanism that appears to be of importance for neurite outgrowth during neuronal differentiation.  (+info)

Selective inhibition of protein kinase C isozymes by Fas ligation. (5/857)

Activation of protein kinase C (PKC) can protect cells from apoptosis induced by various agents, including Fas ligation. To elucidate a possible interaction between Fas-mediated apoptotic signals and activation-related protective signals, we investigated the impact of Fas ligation on PKC activity. We demonstrate that engagement of Fas on human lymphoid Jurkat cells triggered apoptosis, and Fas ligation resulted in partial blockade of cellular PKC activity. The phorbol 12-myristate 13-acetate-mediated translocation of PKCtheta from the cytoplasm to the membrane was inhibited by treatment with anti-Fas antibody, whereas the translocation of PKCalpha or epsilon was not affected. In vitro kinase assay of PKCalpha or epsilon phosphotransferase activity demonstrated that Fas ligation inhibited the ability of PKCalpha to phosphorylate histone H1 as substrate but did not inhibit epsilon isozyme activity. This inhibition of PKCalpha activity mediated by Fas ligation was reversed by okadaic acid, a phosphatase inhibitor, suggesting the involvement of a member of the protein phosphatase 2A subfamily in this component of Fas signaling. Identical patterns of PKC isozyme inhibition were obtained using mouse thymoma cells overexpressing the fas gene (LF(+)). These results suggest that the selective inhibition of a potentially protective, PKC-mediated pathway by Fas activation may, to some extent, contribute to Fas-induced apoptotic signaling.  (+info)

Translocation of protein kinase Cepsilon and protein kinase Cdelta to membrane is required for ultraviolet B-induced activation of mitogen-activated protein kinases and apoptosis. (6/857)

UV-induced signal transduction may be involved in tumor promotion and induction of apoptosis. The role of protein kinase C (PKC) in UVB-induced signal transduction is not well understood. This study showed that UVB markedly induced translocation of membrane-associated PKCepsilon and PKCdelta, but not PKCalpha, from cytosol to membrane. Dominant negative mutant (DNM) PKCepsilon or PKCdelta inhibited UVB-induced translocation of PKCepsilon and PKCdelta, respectively. UVB-induced activation of extracellular signal-regulated protein kinases (Erks) and c-Jun NH2-terminal kinases (JNKs) was strongly inhibited by DNM PKCepsilon and PKCdelta, whereas the DNM of PKCalpha was less effective on the UVB-induced phosphorylation of Erks and JNKs. Among the PKC inhibitors used only rottlerin, a selective inhibitor of PKCdelta, markedly inhibited the UVB-induced activation of Erks and JNKs, but not p38 kinases. Safingol, a selective inhibitor for PKCalpha, did not show any inhibitory effect on UVB-induced mitogen-activated protein kinase activation. GF109203X is a stronger inhibitor of classical PKC than novel PKC. Lower concentrations of GF109203X (<10 microM) had no effect on UVB-induced activation of Erks or JNKs. However, at higher concentrations (over 20 microM), GF109203X inhibited UVB-induced activation of JNKs, Erks, and even p38 kinases. Meanwhile, rottlerin and GF109203X markedly inhibited UVB-induced apoptosis of JB6 cells, whereas safingol had little inhibitory effect. DNM-Erk2 cells and PD98059, a selective inhibitor for mitogen-activated protein kinase/extracellular signal-regulated kinase 1 that directly activates Erks, inhibited UVB-induced apoptosis. DNM-JNK1 cells also blocked UVB-induced apoptosis, whereas SB202190, a specific inhibitor for p38 kinases, did not produce the inhibitory effect. These data demonstrate that PKCdelta and PKCepsilon, but not PKCalpha, mediate UVB-induced signal transduction and apoptosis in JB6 cells through activation of Erks and JNKs.  (+info)

Role of protein kinase C in mitochondrial KATP channel-mediated protection against Ca2+ overload injury in rat myocardium. (7/857)

Growing evidence exists that ATP-sensitive mitochondrial potassium channels (MitoKATP channel) are a major contributor to the cardiac protection against ischemia. Given the importance of mitochondria in the cardiac cell, we tested whether the potent and specific opener of the MitoKATP channel diazoxide attenuates the lethal injury associated with Ca2+overload. The specific aims of this study were to test whether protection by diazoxide is mediated by MitoKATP channels; whether diazoxide mimics the effects of Ca2+ preconditioning; and whether diazoxide reduces Ca2+ paradox (PD) injury via protein kinase C (PKC) signaling pathways. Langendorff-perfused rat hearts were subjected to the Ca2+ PD (10 minutes of Ca2+ depletion followed by 10 minutes of Ca2+ repletion). The effects of the MitoKATP channel and other interventions on functional, biochemical, and pathological changes in hearts subjected to Ca2+ PD were assessed. In hearts treated with 80 micromol/L diazoxide, left ventricular end-diastolic pressure and coronary flow were significantly preserved after Ca2+ PD; peak lactate dehydrogenase release was also significantly decreased, although ATP content was less depleted. The cellular structures were well preserved, including mitochondria and intercalated disks in diazoxide-treated hearts compared with nontreated Ca2+ PD hearts. The salutary effects of diazoxide on the Ca2+ PD injury were similar to those in hearts that underwent Ca2+ preconditioning or pretreatment with phorbol 12-myristate 13-acetate before Ca2+ PD. The addition of sodium 5-hydroxydecanoate, a specific MitoKATP channel inhibitor, or chelerythrine chloride, a PKC inhibitor, during diazoxide pretreatment completely abolished the beneficial effects of diazoxide on the Ca2+ PD. Blockade of Ca2+ entry during diazoxide treatment by inhibiting L-type Ca2+ channel with verapamil or nifedipine also completely reversed the beneficial effects of diazoxide on the Ca2+ PD. PKC-delta was translocated to the mitochondria, intercalated disks, and nuclei of myocytes in diazoxide-pretreated hearts, and PKC-alpha and PKC-epsilon were translocated to sarcolemma and intercalated disks, respectively. This study suggests that the effect of the MitoKATP channel is mediated by PKC-mediated signaling pathway.  (+info)

Isozyme-specific inhibitors of protein kinase C translocation: effects on contractility of single permeabilized vascular muscle cells of the ferret. (8/857)

1. The effects on contractility of three peptides reported to inhibit protein kinase C (PKC) translocation in an isozyme-specific manner were studied: a peptide from the C2 domain of conventional PKCs (C2-2), a peptide from the N-terminal variable domain of epsilonPKC (epsilonV1-2) and a peptide (ABP) from the actin-binding domain of epsilonPKC (epsilon(223-228)). 2. Isometric force was directly recorded from individual hyperpermeable ferret portal vein or aortic smooth muscle cells. 3. Phenylephrine contracted permeabilized portal vein cells at pCa 6.7 but not at pCa 7.0. However, phenylephrine did contract aortic cells at pCa 7.0. 4. C2-2 inhibited phenylephrine-induced contraction, but did not affect resting tension, in portal vein cells at pCa 6.7. In aortic cells at either pCa 6.7 or 7.0, C2-2 had no effect on either basal tension or phenylephrine-induced contraction. 5. ABP did not evoke any changes in phenylephrine-induced contraction or baseline tension in either portal vein or aortic cells. 6. epsilonV1-2 inhibited phenylephrine-induced contraction and decreased resting tension in aortic cells at pCa 7.0, but not in portal vein cells at pCa 6.7. 7. Western blots indicated that portal vein cells contained substantially more alphaPKC than aortic cells. Portal vein cells also contained small amounts of betaPKC, which was undetectable in aortic cells. In contrast, aortic cells contained more epsilonPKC than portal vein cells. Even though epsilonPKC was expressed in portal vein and alphaPKC in aorta, imaging studies indicated that they were not translocated in these cell types. 8. These results suggest that the Ca2+-dependent isozymes of PKC (alpha and/or beta) play a major role in contraction of the portal vein but not of the aorta. In contrast, the results are consistent with epsilonPKC, but not Ca2+-dependent PKC isozymes, regulating contractility of the aorta.  (+info)

TY - JOUR. T1 - Protein Kinase C Epsilon Promotes Cerebral Ischemic Tolerance Via Modulation of Mitochondrial Sirt5. AU - Morris-Blanco, Kahlilia C.. AU - Dave, Kunjan R.. AU - Saul, Isabel. AU - Koronowski, Kevin B.. AU - Stradecki, Holly M.. AU - Perez-Pinzon, Miguel A.. PY - 2016/7/20. Y1 - 2016/7/20. N2 - Sirtuin 5 (SIRT5) is a mitochondrial-localized NAD +-dependent lysine desuccinylase and a major regulator of the mitochondrial succinylome. We wanted to determine whether SIRT5 is activated by protein kinase C epsilon (PKC?)-mediated increases in mitochondrial Nampt and whether SIRT5 regulates mitochondrial bioenergetics and neuroprotection against cerebral ischemia. In isolated mitochondria from rat cortical cultures, PKC? activation increased SIRT5 levels and desuccinylation activity in a Nampt-dependent manner. PKC? activation did not lead to significant modifications in SIRT3 activity, the major mitochondrial lysine deacetylase. Assessments of mitochondrial bioenergetics in the cortex ...

We have previously shown that deletion of protein kinase C epsilon (PKCepsilon) in mice results in protection against glucose intolerance caused by a high fat diet. This was in part due to reduced insulin uptake by hepatocytes and insulin clearance, which enhanced insulin availability. Here we employed mouse embryonic fibroblasts (MEFs) derived from wildtype (WT) and PKCepsilon-deficient (PKCepsilon(-/-)) mice to examine this mechanistically. PKCepsilon(-/-) MEFs exhibited reduced insulin uptake which was associated with decreased insulin receptor phosphorylation, while downstream signalling through IRS-1 and Akt was unaffected. Cellular fractionation demonstrated that PKCepsilon deletion changed the localization of the insulin receptor, a greater proportion of which co-fractionated with flotillin-1, a marker of membrane microdomains. Insulin stimulation resulted in redistribution of the receptor in WT cells, while this was markedly reduced in PKCepsilon(-/-) cells. These alterations in insulin receptor

The roles of MEK, ERK, the epsilon and alpha isoforms of protein kinase C (PKC), and caveolin-1 in regulating collagen expression were studied in normal lung fibroblasts. Knocking down caveolin-1 gave particularly striking results. A 70% decrease caused a 5-fold increase in MEK/ERK activation and collagen expression. The combined data reveal a branched signaling pathway. In its central portion MEK activates ERK, leading to increased collagen expression. Two branches converge on MEK/ERK. In one, increased PKCepsilon leads to MEK/ERK activation. In another, increased PKCalpha induces caveolin-1 expression, which in turn inhibits MEK/ERK activation and collagen expression. Lung fibroblasts from scleroderma patients with pulmonary fibrosis showed altered signaling. Consistent with their overexpression of collagen, scleroderma lung fibroblasts contain more activated MEK/ERK and less caveolin-1 than normal lung fibroblasts. Because cutaneous fibrosis is the hallmark of scleroderma, we also studied ...

While protein kinase C epsilon has been shown to contribute to acute and chronic mechanical hyperalgesia, its upstream signaling pathway has received little attention. Since phospholipase C can signal to PKC epsilon and has been implicated in nociceptor sensitization, we tested if it is upstream of …
Several of the actions of ethanol are mediated by gamma-aminobutyrate type A (GABA(A)) receptors. Here we demonstrated that mutant mice lacking protein kinase C epsilon (PKCepsilon) were more sensitive than wild-type littermates to the acute behavioral effects of ethanol and other drugs that alloste …
The amyloid-beta protein precursor (AbetaPP) is an integral membrane protein subjected to constitutive and regulated proteolytic processing. We have previously demonstrated that protein kinase C epsilon (PKCepsilon) plays a key role in the regulation of AbetaPP metabolism via cholinergic receptors. The purpose of the present work is to clarify whether other putative signaling systems are involved in the same pharmacological pathway. We focused particularly on casein kinase 2 (CK2), demonstrating a direct interaction between PKCepsilon and CK2 following cholinergic stimulation. Treatment of human neuroblastoma SH-SY5Y cells with a selective inhibitor of CK2 reduced the effect of carbachol on the release of sAbetaPPalpha. This treatment did not influence the activation and translocation of PKCepsilon suggesting that the latter is located upstream of CK2. On the basis of our results, we add another player to the complex cellular mechanisms regulating non-amyloidogenic processing of AbetaPP. ...

At concentrations found in humans after ingestion of one to two cups of green tea, epicatechin-3-gallate (ECG) modulates Na/K-ATPase conformation and activity. Akin to ouabain, an archetypal Na/K-ATPase ligand of the cardiotonic steroid (CTS) family, ECG also activates protein kinase C epsilon type (PKCε) translocation and increases the force of contraction of the rat heart. This study evaluated whether, like ouabain, ECG also modulates Na/K-ATPase/Src receptor function and triggers pre- and postconditioning against ischemia/reperfusion (I/R) injury. In vitro, ECG activated the purified Na/K-ATPase/Src complex. In Langendorff-perfused rat hearts, submicromolar concentrations of ECG administered either before or after ischemia reduced infarct size by more than 40%, decreased lactate dehydrogenase release, and improved the recovery of cardiac function. ECG protection was blocked by PKCε inhibition and attenuated by mitochondrial KATP channel inhibition. In a unique mammalian cell system with ...
Cancer cells use the Protein Kinase C epsilon (in short PKCƐ signal pathway), which is very rarely used by the normal cells. It could be important to target some cancers cells as these cells rely on this pathway for survival.. The pathway helps the cancer cells to untangle and separate their DNA, which in turn helps the cancer cells to survive even after DNA errors. This signal pathway is more often used by cancer cells than normal cells as the DNA of these cancer cells is more jumbled and prone to becoming tangled. Cancer cells can be triggered be self-destruct by turning off this signal pathway because the machinery that helps the cancer cell untangle the DNA fails. This mean, as the cancer cells tries to divide, it is torn apart, ravaging and causing huge breaks in the code that leads to demise of cancer cells.. Dr Nicola Brownlow said that turning off this line of provided by PKCƐ signal pathway could turn out to be powerful way of targeting cancer cells, and make them self-destruct. Dr. ...

TY - JOUR. T1 - Epsilon PKC Increases Brain Mitochondrial SIRT1 Protein Levels via Heat Shock Protein 90 following Ischemic Preconditioning in Rats. AU - Thompson, John W.. AU - Dave, Kunjan R.. AU - Saul, Isabel. AU - Narayanan, Srinivasan V.. AU - Perez-Pinzon, Miguel A.. PY - 2013/9/13. Y1 - 2013/9/13. N2 - Ischemic preconditioning is a neuroprotective mechanism whereby a sublethal ischemic exposure is protective against a subsequent lethal ischemic attack. We previously demonstrated that SIRT1, a nuclear localized stress-activated deacetylase, is vital for ischemic preconditioning neuroprotection. However, a recent study demonstrated that SIRT1 can also localize to the mitochondria. Mitochondrial localized SIRT1 may allow for a direct protection of mitochondria following ischemic preconditioning. The objective of this study was to determine whether ischemic preconditioning increases brain mitochondrial SIRT1 protein levels and to determine the role of PKCe{open} and HSP90 in targeting SIRT1 ...
Protein Kinase C epsilon (PKC∈), a member of the PKC family of phorbol ester/diacylglycerol receptors, has been shown to be up-regulated in human prostate cancer specimens. As PKC∈ plays an important role in prostate cancer cell survival and cooperates with other oncogenic insults, we hypothesized that PKC∈ may regulate NF-κB signaling pathway, known to be highly dysregulated during prostate tumorigenesis. Similar to human tumors, we observed high PKC∈ overexpression in prostate cancer cell lines compared to normal immortalized RWPE-1 cells. PKC∈ depletion using siRNA or its pharmacological inhibition in LNCaP cells resulted in decreased TNFα-induced IκBα phosphorylation and degradation, as well as decreased NF-κB nuclear translocation and transactivation of NF-κB reporter activity. Conversely, significant enhancements in these TNFα-induced responses were observed in LNCaP cells upon PKC∈ overexpression using an adenoviral approach. Interestingly, TNFα treatment led to ...
Pulsatile (PSS) versus oscillatory (OSS) shear stress differentially modulates mechano-signal transduction with implications in atheroprotection and atherogenesis. In response to ischemia and reperfusion injury, Protein Kinase C isoform epsilon (PKCε) signaling in mitochondria confers cardioprotection. It is unknown whether PKCε was shear stress responsive via endothelial growth factor receptor (VEGFR) signaling with an implication in vascular endothelial repair. Both PSS (time-averaged shear stress (τave) = 25 dyne/cm2 at 1 Hz for 4 hr) and OSS (τave= 0.1±3 dyne/cm2 at 1 Hz for 4 hr) up-regulated PKCε mRNA by 1.7±0.2-fold and 1.5±0.1-fold in human aortic endothelial cells (HAEC), respectively, and protein expression by 1.5±0.1-fold and by 1.4±0.1-fold, respectively, which were inhibited in the presence of VEGFR-inhibitor, Cediranib (p , 0.05, n=4). Treatment with VEGF (100ng/ml) further up-regulated PKCε mRNA expression by 2.3±0.2-fold at 1 hour (p , 0.01, n=3). Matrigel assays ...

Protein kinase Cepsilon (PKCε) exerts a well-known cardio-protective activity in ischemia-reperfusion injury and plays a pivotal role in stem cell proliferation and differentiation. Although many studies have been performed on physiological and morphological effects of PKCε mis-expression in cardiomyocytes, molecular information on the role of PKCε on early cardiac gene expression are still lacking. We addressed the molecular role of PKCε in cardiac cells using mouse cardiomyocytes and rat bone marrow mesenchymal stem cells. We show that PKCε is modulated in cardiac differentiation producing an opposite regulation of the cardiac genes NK2 transcription factor related, locus 5 (nkx2.5) and GATA binding protein 4 (gata4) both in vivo and in vitro. Phospho-extracellular regulated mitogen-activated protein kinase 1/2 (p-ERK1/2) levels increase in PKCε over-expressing cells, while pkcε siRNAs produce a decrease in p-ERK1/2. Indeed, pharmacological inhibition of ERK1/2 rescues the expression ...
JSH-23 is a nuclear factor-kappa B (NF-κB) nuclear translocation inhibitor. JSH-23 inhibits LPS and cytokine-induced nuclear translocation of the p65 subunit of NF-kB as analyzed by EMSA and western blot. JSH-23 treatment significantly reversed the nerve conduction and nerve blood flow deficits seen in diabetic animals. Reduction in mechanical pain threshold was also partially corrected by the treatment. Protein expression studies showed that nuclear translocation of p65/p50 subunit was inhibited by JSH-23 treatment in the sciatic nerve..

The epsilon isoform of diacylglycerol kinase (DGKepsilon) is unique among mammalian DGKs in having a segment of hydrophobic amino acids comprising approximately residues 20 to 41. Several algorithms predict this segment to be a transmembrane (TM) helix. Using PepLook, we have performed an in silico analysis of the conformational preference of the segment in a hydrophobic environment comprising residues 18 to 42 of DGKepsilon. We find that there are two distinct groups of stable conformations, one corresponding to a straight helix that would traverse the membrane and the second corresponding to a bent helix that would enter and leave the same side of the membrane. Furthermore, the calculations predict that substituting the Pro32 ...

Smooth muscle is responsible for the contractility of hollow organs, such as blood vessels, the gastrointestinal tract, the bladder, and the uterus. Its structure differs greatly from that of skeletal muscle. The human stomach contains three layers of muscle in its walls, the outer longitudinal, the middle circular and the inner oblique and visceral smooth muscle cells makes up all three layers along the entire organ. Smooth muscle contraction is critical to peristalsis in the human stomach and the contraction may be mediated by activation of phospholipase through two distinct mechanisms (increased intracellular Ca2+ and G protein activation) and activating PKCepsilon-dependent mechanisms. In vitro study also shows that gastric smooth muscle cells express ET and eNOS and both calcium and sodium may be involved as current carriers in the generation of the plateau potential.HGSMC from Bioarray Research Laboratories are isolated from the human stomach. HGSMC are cryopreserved at secondary culture ...

Translocation of these novel PKC isoenzymes occurred significantly more slowly than either eGFP-PKCα or Ca2+, with t10-90 times in the range 25-30 s. Translocation of the DAG sensor (eGFP-C12) occurred with a similar time course which, together with the lack of requirement for an elevation of [Ca2+]i (Fig. 6), suggests that translocation of both eGFP-PKCδ and eGFP-PKCε is predominantly driven by changes in DAG. This is consistent with the dogma that nPKCs are DAG sensitive and Ca2+ insensitive. However, our experiments using BAPTA to annul changes in [Ca2+]i revealed additional complexity. eGFP-PKCδ translocated more rapidly in BAPTA-loaded cells and at the peak of the response a greater proportion of eGFP-PKCδ had translocated to the membrane. However, the total translocation during the response was similar in the presence or absence of BAPTA, suggesting that eGFP-PKCδ translocated more quickly, but not to a greater degree, in the absence of a Ca2+ response. It seems unlikely that this ...
I understand, to some extent, Tates thesis. Could somebody explain perhaps what are the epsilon factors in Beilinsons works, such as $\epsilon$-factors for Gauss-Manin determinants, or Topological $\epsilon$-factors? How do they mimic the usual ones? Are they some categorification (since the usual one is a number, and those ones seem to be lines)? Is there some intuition for the construction in Topological $\epsilon$-factors or, perhaps more importantly, for the need for construction?. Edit: I also know vaguely that epsilon-factors should be also associated to Galois-side-data, and the ones in Beilinsons works mimic those, and not the automorphic ones from Tates thesis.. Thank you, Sasha. ...

Deletion of autoreactive thymocytes at the DP stage is the basis for tolerance to thymus-expressed self antigens. In this study we investigated whether distinct signalling pathways are induced in DP thymocytes as compared to mature T cells upon stimulation with antigen. Using triple transgenic mice expressing a TCR transgene, dominant negative ras/Mek proteins and a reporter gene construct with AP-1 or NF-kappa B binding sites, we showed a complete lack of transcriptional activity of NF-kappa B but not AP-1 in DP thymocytes, whereas both were transcriptionally active in mature T cells after antigenic stimulation. Lack of NF-kappa B induction correlated with increased death in response to antigen. AP-1 induction was dependent on the integrity of the ras/Mek pathway indicating that this pathway was activated in the DP thymocytes. In contrast, we found a complete lack of constitutive expression of the epsilon isoform of Protein Kinase C (PKC) in DP thymocytes, although it was present in mature thymocytes
Translocation of PKC isoforms has been implicated in mechanisms involved in heart failure, 22myocardial hypertrophy, 23and preconditioning. PKC isoforms are activated by phosphorylating enzymes such as G proteins and are modified in enzyme activity by phospholipids, diacylglycerol, increased Ca2+, nitric oxide, and superoxide anions. This is followed by translocation in an isoform-specific and cytoskeleton-mediated manner to subcellular targets, which can be directly visualized by immunohistochemical methods. Only 10 min of ischemia 24or brief administrations of pharmacologic agents 11,25may elicit significant PKC translocation. Recent evidence indicates that translocation is dependent on PKC binding to a family of proteins called receptors of activated C kinase. 26These anchoring proteins are highly specific, and each PKC isoenzyme can bind to only one receptor of activated C kinase. Thus, different PKC isoforms may be linked to distinctive aspects of myocardial function, and this functional ...
Background/Aims: We have previously reported that ischemia/reperfusion injury (IRI) to the kidney leads to induced expression of RACK1 and changes in the level of expression and subcellular distribution of PKC isozymes α, βII and ζ. In order to further define the role of PKC isozymes in IRI we investigated the effect of activation or inhibition of the isozymes on cytotoxicity mediated by H|sub|2|/sub|O|sub|2|/sub| in LLCPK|sub|1|/sub| cells. Methods: Cytotoxicity was analyzed by Trypan blue assay and LDH release assay. Translocation of PKC isozymes postinjury in LLCPK1 cells was analyzed by immunostaining and Western blot analysis. Results: Western blot analysis showed that the expression of PKC-α was up-regulated in a triphasic pattern with the initial induction within the first 10 min of injury followed by higher levels of expression at 2 and 24 h postinjury. The expression of PKC-ζ was highly induced within the first 15 min of injury but its expression was down-regulated to that of normal

TY - JOUR. T1 - Protein kinase Cδ mediates histamine-evoked itch and responses in pruriceptors. AU - Valtcheva, Manouela V.. AU - Davidson, Steve. AU - Zhao, Chengshui. AU - Leitges, Michael. AU - Gereau, Robert W.. N1 - Publisher Copyright: © Valtcheva et al. Copyright: Copyright 2017 Elsevier B.V., All rights reserved.. PY - 2015/1/6. Y1 - 2015/1/6. N2 - Itch-producing compounds stimulate receptors expressed on small diameter fibers that innervate the skin. Many of the currently known pruritogen receptors are Gq Protein-Coupled Receptors (GqPCR), which activate Protein Kinase C (PKC). Specific isoforms of PKC have been previously shown to perform selective functions; however, the roles of PKC isoforms in regulating itch remain unclear. In this study, we investigated the novel PKC isoform PKCδ as an intracellular modulator of itch signaling in response to histamine and the non-histaminergic pruritogens chloroquine and β-alanine. Results: Behavioral experiments indicate that PKCδ knock-out ...
Protein kinases C (PKCs) are ubiquitously expressed and play critical roles in a plethora of physiological and pathophysiological processes. Owing to PKCs highly conserved phosphorylation consensus sequence, it has been difficult to distinguish the role of individual PKC isoforms. Recently, the identification of novel membrane targeting via subcellularly targeted diacylglycerol production found for novel PKCs (nPKCs), together with a characterization of their putative functions, has shed new light on the specific roles of individual PKCs in cellular processes. ...

We selected and characterized a 30-fold etoposide (VP-16)-resistant subline of K562 human leukemia cells (K/VP.5) that exhibits quantitative and qualitative changes in topoisomerase II, including hypophosphorylation of this drug target. The initial rate of topoisomerase II phosphorylation was reduced 3-fold in K/VP.5 compared with K562 cells, but the rate of dephosphorylation was similar. Analysis of potential topoisomerase II protein kinases revealed a 3-fold reduction in the level of the beta II protein kinase C (PKC) in K/VP.5 cells, whereas levels of alpha- and epsilon PKC, casein kinase II, p42map kinase, and p34cdc2 kinase were comparable for both cell lines. The PKC activator, bryostatin 1, together with K562 nuclear extracts potentiated VP-16-induced topoisomerase II/DNA covalent complex formation in nuclei isolated from K/VP.5 cells but not from K562 cells. Bryostatin 1 effects were blocked by the PKC inhibitor 7-O-methyl-hydroxy-staurosporine. Bryostatin 1 also up-regulated ...
TY - JOUR. T1 - Rottlerin inhibits tonicity-dependent expression and action of TonEBP in a PKCδ-independent fashion. AU - Zhao, Hongyu. AU - Tian, Wei. AU - Cohen, David M.. PY - 2002. Y1 - 2002. N2 - Novel protein kinase C (PKC) isoforms PKCδ and PKCε have recently been implicated in signaling by hypertonic stress. We investigated the role of the putative PKCδ inhibitor rottlerin on tonicity-dependent gene regulation. In the renal medullary mIMCD3 cell line, rottlerin blocked tonicity-dependent transcription of a tonicity enhancer (TonE)-driven luciferase reporter gene, as well as tonicity-dependent transcription of the physiological tonicity effector gene aldose reductase, but not urea-dependent transcription. Consistent with these data, rottlerin inhibited tonicity-dependent expression of TonE binding protein (TonEBP) at the mRNA and protein levels. Another inhibitor of both novel and conventional PKC isoforms, GF-109203X, suppressed TonEBP-dependent transcription but failed to influence ...

One of the key findings of this study is that whereas metformins sex differential effect on neuropathic pain (Inyang et al., 2019) can also be observed in the incisional pain model, other AMPK activators did not have a sex-specific effect on pain in our experiments. NCLS, ZLN-024, and MK 8722 all had the same level of efficacy on hyperalgesic priming in male and female mice. Metformin had a robust initial antihyperalgesic effect and blocked hyperalgesic priming in male mice but showed no effect in female mice. These sex differences are not readily explained by the pharmacokinetics of metformin. In fact, female mice had higher plasma and brain levels of metformin than did male mice. Although we do not have an explanation for the sex differences in metformins efficacy in incisional or neuropathic pain models in mice, our work does illustrate that other AMPK activators can be effective in the incisional model in both sexes. A possible mechanism that can be explored in future work is sexual ...
TY - JOUR. T1 - A novel protein kinase C (PKCε) is required for fMet-Leu-Phe-induced activation of NF-κB in human peripheral blood monocytes. AU - Chen, Ling Yu. AU - Doerner, Astrid. AU - Lehmann, Paul F.. AU - Huang, Shuang. AU - Zhong, Guangming. AU - Pan, Zhixing K.. PY - 2005/6/10. Y1 - 2005/6/10. N2 - We have reported that the chemoattractant, fMet-Leu-Phe (fMLP), induces the activation of NF-κB in human peripheral blood monocytes and that this requires the activity of small GTPase, RhoA (Huang, S., Chen, L.-Y., Zuraw, B. L., Ye, R. D., and Pan, Z. K. (2001) J. Biol. Chem. 276, 40977-40981). Here we showed that the novel protein kinase C isozyme, PKCε, associates functionally with RhoA in fMLP-stimulated monocytes and that PKCε acted as a signaling component downstream of the GTPase RhoA during fMLP-induced activation of NF-κB. Stimulation of monocytes with fMLP resulted in activation of both PKCε and NF-κB. This latter activation was largely blocked by specific inhibitors of PKCε ...
TY - JOUR. T1 - Inhibition of the spontaneous rate of contraction of neonatal cardiac myocytes by protein kinase C isozymes. T2 - A putative role for the ε isozyme. AU - Johnson, John A. AU - Mochly-Rosen, Daria. PY - 1995/1/1. Y1 - 1995/1/1. N2 - Protein kinase C (PKC) enzymes regulate numerous cardiac functions. In the present study, we determined the effects of the PKC-activating drug 4-β phorbol 12-myristate 13-acetate (4-β PMA) on the rate of contraction and correlated these changes with the distribution and levels of α-, β-, δ-, ε-, and ζ-PKC isozymes by using neonatal rat cardiac myocytes in culture. Treatment with 0.3 to 100 nmol/L 4-β PMA caused negative chronotropic effects on contraction. This effect was maximal at a concentration of 3 nmol/L 4-β PMA and correlated with redistribution of the α- and ε-PKC isozymes from the cytosolic to the particulate cell fraction. After a 1-hour treatment with 100 nmol/L PMA, the α- and β-PKC isozymes and an 80-kD ζ- like PKC isozyme ...
