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..
MK-8591 is a long acting nucleoside reverse transcriptase translocation inhibitor (NRTTI) that has demonstrated potent antiviral activity in HIV-1 infected subjects administered a once-weekly (QW) 10 mg dose as monotherapy in a clinical trial and in SIV-infected rhesus macaque models. MK-8591 extended duration dosing potential was suggested by the long-intracellular half-life of MK-8591-triphosphate (MK-8591-TP) in peripheral blood mononuclear cells (PBMCs) in vitro and in preclinical models. Here we describe the tissue distribution of MK-8591 and its anabolites in rats by quantitative whole body autoradiography and in rhesus vaginal and rectal mucosa by biopsy.. Wistar Hannover rats dosed orally at 50 mpk (mg/kg) of [14C]-MK-8591 were sacrificed at 0.5 hr and 24 hr, cryo-sectioned (40 μm thick sagittal), and phosphor imaged for 4 days. Radioactivity in tissues was quantified using the blood standards along with Raytest AIDA image analysis software. For rectal and vaginal tissue distribution ...

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 ...

Multiple protein kinase C (PKC) isozymes are present in neurons, where they regulate a variety of cellular functions. Due to the lack of specific PKC isozyme inhibitors, it remains unknown how PKC acts on its selective target(s) and achieves its specific actions. Here we show that a PKC binding prot …

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

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 ...

The Ca2+-insensitive protein kinase C (PKC) isoforms ε, η, δ and ζ are possible direct downstream targets of phosphatidylinositol 3-kinase (PI3-K), and might therefore be involved in insulin signalling. Although isoform-specific changes in PKC expression have been reported for skeletal muscle and liver in insulin-resistant states, little is known about these isoforms in adipocytes. Therefore we studied (1) expression and subcellular localization of these isoforms in murine adipocytes, (2) translocation of specific isoforms to membranes in response to treatment with insulin and phorbol 12-myristate 13-acetate (PMA) and (3) regulation of expression in insulin-resistant states. The PKC isoforms ε, η, δ and ζ are expressed in adipocytes. Immunoreactivity for all isoforms is higher in the membranes than in the cytosol, but subcellular fractionation by differential centrifugation shows an isoform-specific distribution within the membrane fractions. PMA treatment of adipocytes induces ...
The data presented in this study demonstrate that activation of PKC-ε on stimulation of the A1R in the rat or mouse heart elicits the translocation of the kinase to a RACK2 protein of the cardiomyocyte. Previously, we reported A1R activation promotes the translocation of PKC-ε, but not PKC-δ, to the t-tubules of the cardiomyocyte (30). The present data indicate that RACK2 was the target protein for this translocation. Our present observations include the measurement of contractile activity of isolated cardiomyocytes and the visualization with imaging (rat) and coimmunoprecipitation of the kinase and RACK2 (rat and mouse). Translocation of PKC-ε to RACK2 occurred whether the PKC-ε was activated nonspecifically by a phorbol ester, or by A1R activation with PIA, or with the selective agonist CCPA. The action induced by CCPA was selective for the A1R, as indicated by the inhibition elicited by the A1R antagonist DPCPX. Furthermore, PKC-ε translocation most likely results from an A1R-induced ...

Pathogenic Burkholderia rely on host factors for efficient intracellular replication and are highly refractory to antibiotic treatment. To identify host genes that are required by Burkholderia spp. during infection, we performed a RNA interference (RNAi) screen of the human kinome and identified 35 host kinases that facilitated Burkholderia thailandensis intracellular survival in human monocytic THP-1 cells. We validated a selection of host kinases using imaging flow cytometry to assess efficiency of B. thailandensis survival in the host upon siRNA-mediated knockdown. We focused on the role of the novel protein kinase C isoform, PKC-η, in Burkholderia infection and characterized PKC-η/MARCKS signaling as a key event that promotes the survival of unopsonized B. thailandensis CDC2721121 within host cells. While infection of lung epithelial cells with unopsonized Gram-negative bacteria stimulated phosphorylation of Ser175/160 in the MARCKS effector domain, siRNA-mediated knockdown of PKC-η ...
This study demonstrates that different PKC isoforms are differentially expressed in particular cellular components of ovarian follicles of pre-pubertal, pubertal and adult mouse ovaries.. Data obtained from H-Score evaluation of immunohistochemistry findings revealed that PKCα expression was more apparent in oocytes of all follicles in pre-pubertal, pubertal and adult ovaries, though it was also expressed in granulosa cells. Interestingly, in adult and pre-pubertal ovaries, intense immunostaining of PKCα in oocytes was statistically significant in primordial (PND60, PND7 and PND1), primary (PND60, PND7 and PND1) and secondary follicles (PND60 and PND7), whereas in PND21 ovaries only oocytes of primordial follicles had significantly higher immunostaining level of PKCα. These findings support the idea that PKCα expression in oocytes of larger follicles may have low significance due to granulosa-oocyte interactions during initiation of hormone dependent follicular growth [27],[28]. PKCα ...
The members of the protein kinase C (PKC) family consist of serine/threonine kinases classified according to their regulatory domain. Those that belong to the novel PKC subfamily, such as PKCδ, are dependent on diacylglycerol but not Calcium when considering their catalytic activity. Although several studies have shown the importance of PKCδ in different cellular events in health and disease, the overall in vivo distribution of this PKC isoform during development is still lacking. Through Lac Z and antibody staining procedures, we show here the in vivo expression of PKCδ during mouse embryogenesis. Ganglia were the domains with most prominent expression of PKCδ in most of the stages analysed, although PKCδ could also be detected in heart and somites at earlier stages, and cartilage primordium and skin among other sites in older embryos. The strong expression of PKCδ in ganglia during murine development shown in this study suggests a significant role of this isoform as well as redundancy with other
