    ABSTRACT: WbpP encoding UDP-GlcNAC C4 epimerase is responsible for the activation of virulence factor in marine pathogen Vibrio vulnificus (V. vulnificus) and it is linked to many aquatic diseases, thus making it a potential therapeutic target. There are few reported compounds that include several natural products and synthetic compounds targeting Vibrio sp, but specific inhibitor targeting WbpP are unavailable. Here, we performed structure-based virtual screening using chemical libraries such as Binding, TOSLab and Maybridge to identify small molecule inhibitors of WbpP with better drug-like properties. Deficient structural information forced to model the structure and the stable protein structure was obtained through 30 ns of MD simulations. Druggability regions are focused for new lead compounds and our screening protocol provides fast docking of entire small molecule library with screening criteria of ADME/Lipinski filter/Docking followed by re-docking of top hits using a method that incorporates both ligand and protein flexibility. Docking conformations of lead molecules interface displays strong H-bond interactions with the key residues Gly101, Ser102, Val195, Tyr165, Arg298, Val209, Ser142, Arg233 and Gln200. Subsequently, the top-ranking compounds were prioritized using the molecular dynamics simulation-based conformation and stability studies. Our study suggests that the proposed compounds may aid as a starting point for the rational design of novel therapeutic agents.

    ABSTRACT: R4/B subfamily RGS (regulator of G protein signaling) proteins play roles in regulation of many GPCR-mediated responses. Multiple RGS proteins are usually expressed in a cell, and it is difficult to point out which RGS protein species are functionally important in the cell. To evaluate intrinsic potency of these RGS proteins, we compared inhibitory effects of RGS1, RGS2, RGS3, RGS4, RGS5, RGS8 and RGS16 on AT1 receptor signaling. Intracellular Ca(2+) responses to angiotensin II were markedly attenuated by transiently expressed RGS2, RGS3 and RGS8, compared to weak inhibition by RGS1, RGS4, RGS5 and RGS16. N-terminally deleted RGS2 (RGS2 domain) lost this potent inhibitory effect, whereas RGS domains of RGS3 and RGS8 showed strong inhibition similar to those of the full-length proteins. To investigate key determinants that specify the differences in potency, we constructed chimeric domains by replacing one or two of three exon parts of RGS8 domain with the corresponding part of RGS5. The chimeric RGS8 domains containing the first or the second exon part of RGS5 showed strong inhibitory effects similar to that of wild type RGS8, but the chimeric domain with the third exon part of RGS5 lost its activity. On the contrary, replacement of the third exon part of RGS5 with the corresponding residues of RGS8 increased the inhibitory effect. The role of the third exon part of RGS8 domain was further confirmed with the chimeric RGS8/RGS4 domains. These results indicate the potent inhibitory activity of RGS8 among R4/B subfamily proteins and importance of the third exon.

    ABSTRACT: Aldosterone acts on its target tissue through a classical mechanism or through the rapid pathway through a putative membrane-bound receptor. Our goal here was to better understand the molecular and biochemical rapid mechanisms responsible for aldosterone-induced cardiomyocyte hypertrophy. We have evaluated the hypertrophic process through the levels of ANP, which was confirmed by the analysis of the superficial area of cardiomyocytes. Aldosterone increased the levels of ANP and the cellular area of the cardiomyocytes; spironolactone reduced the aldosterone-increased ANP level and cellular area of cardiomyocytes. Aldosterone or spironolactone alone did not increase the level of cyclic 3',5'-adenosine monophosphate (cAMP), but aldosterone plus spironolactone led to increased cAMP level; the treatment with aldosterone + spironolactone + BAPTA-AM reduced the levels of cAMP. These data suggest that aldosterone-induced cAMP increase is independent of mineralocorticoid receptor (MR) and dependent on Ca2+. Next, we have evaluated the role of A-kinase anchor proteins (AKAP) in the aldosterone-induced hypertrophic response. We have found that St-Ht31 (AKAP inhibitor) reduced the increased level of ANP which was induced by aldosterone; in addition, we have found an increase on protein kinase C (PKC) and extracellular signal-regulated kinase 5 (ERK5) activity when cells were treated with aldosterone alone, spironolactone alone and with a combination of both. Our data suggest that PKC could be responsible for ERK5 aldosterone-induced phosphorylation. Our study suggests that the aldosterone through its rapid effects promotes a hypertrophic response in cardiomyocytes that is controlled by an AKAP, being dependent on ERK5 and PKC, but not on cAMP/cAMP-dependent protein kinase signaling pathways. Lastly, we provide evidence that the targeting of AKAPs could be relevant in patients with aldosterone-induced cardiac hypertrophy and heart failure.

    ABSTRACT: CD2-associated protein is one of the most important slit diaphragm proteins in maintaining podocyte integrity and reducing proteinuria. In the last 15 years, progressive researches have shown that CD2AP serves as an adaptor protein, plays essential roles in the podocyte cytoskeletal structure and signaling from the extracellular SD to the intracellular dynamic actin cytoskeleton. CD2AP deficient or transcript abnormality would lead to podocyte failure and proteinuric glomerular diseases. In this study, we demonstrate that CD2AP and p85 regulatory subunit of phosphoinositide 3-OH kinase (PI3K), recruit PI3K to the plasma membrane, and stimulate PI3K-dependent AKT signaling in podocytes the CD2AP-mediated AKT activity can regulate complex biological programs. PAN reduces Akt phosphorylation levels of GSK3β, LY294002 can promote podocyte apoptosis induced by PAN. Our findings suggest that the activation of PI3K/AKT signaling represents an essential component to maintain the functional integrity of podocytes. And PI3K/Akt signaling pathway play an important role in podocyte apoptosis.

    ABSTRACT: The current study was designed to evaluate the in vitro antiproliferative activity of 1,8-dihydroxy-4-methylanthracene-9,10-dione (DHMA) isolated from the Luffa acutangula against human non-small cell lung cancer cell line (NCI-H460). Induction of apoptosis and reactive oxygen species (ROS) generation was determined through fluorescence microscopic technique. Quantitative real-time PCR and western blotting analysis was carried out to detect the expression of pro-apoptotic (p53, p21, caspase-3, Bax, GADD45A, and ATM) and anti-apoptotic (NF-κB) proteins in NCI-H460 cell line. In silico studies also performed to predict the binding mechanism of DHMA with MDM2-p53 protein. The DHMA inhibited the cell viability of NCI-H460 cells in a dose-dependent manner with an IC50 of about 50 µg/ml. It significantly reduced cell viability correlated with induction of apoptosis, which was associated with ROS generation. The apoptotic cell death was further confirmed through dual staining and DNA fragmentation assay. DHMA significantly increased the expression of anti-apoptotic protein such as p53, p21, Bax, and caspase-3 but downregulated the expression of NF-κB in NCI-H460 cell line. In silico studies demonstrate that DHMA formed hydrogen bond interaction with key residues Trp26, Phe55 and Lys24 by which it disrupt the binding of p53 with MDM2 receptor. These findings suggested that DHMA induces apoptosis in NCI-H460 via a p53-dependent pathway. This the first study on cytotoxic and apoptosis inducing activity of DHMA from L. acutangula against NCI-H460 cell line. Therefore, DHMA has therapeutic potential for lung cancer treatment.

    ABSTRACT: Emerging data on cancer suggesting that target-based therapy is promising strategy in cancer treatment. PI3K-AKT pathway is extensively studied in many cancers; several inhibitors target this pathway in different levels. Recent finding on this pathway uncovered the therapeutic applications of PI3K-specific inhibitors; PI3K, AKT, and mTORC broad spectrum inhibitors. Noticeably, class I PI3K isoforms, p110γ and p110δ catalytic subunits have rational therapeutic application than other isoforms. Therefore, three classes of inhibitors: isoform-specific, dual-specific and broad spectrum were selected for molecular docking and dynamics. First, p110δ structure was modelled; active site was analyzed. Then, molecular docking of each class of inhibitors were studied; the docked complexes were further used in 1.2 ns molecular dynamics simulation to report the potency of each class of inhibitor. Remarkably, both the studies retained the similar kind of protein ligand interactions. GDC-0941, XL-147 (broad spectrum); TG100-115 (dual-specific); and AS-252424, PIK-294 (isoform-specific) were found to be potential inhibitors of p110γ and p110δ, respectively. In addition to that pharmacokinetic properties are within recommended ranges. Finally, molecular phylogeny revealed that p110γ and p110δ are evolutionarily divergent; they probably need separate strategies for drug development.

    ABSTRACT: While α1-adrenergic receptors (ARs) have been previously shown to limit ischemic cardiac damage, the mechanisms remain unclear. Most previous studies utilized low oxygen conditions in addition to ischemic buffers with glucose deficiencies, but we discovered profound differences if the two conditions are separated. We assessed both mouse neonatal and adult myocytes and HL-1 cells in a series of assays assessing ischemic damage under hypoxic or low glucose conditions. We found that α1-AR stimulation protected against increased lactate dehydrogenase release or Annexin V+ apoptosis under conditions that were due to low glucose concentration not to hypoxia. The α1-AR antagonist prazosin or nonselective protein kinase C (PKC) inhibitors blocked the protective effect. α1-AR stimulation increased 3H-deoxyglucose uptake that was blocked with either an inhibitor to glucose transporter 1 or 4 (GLUT1 or GLUT4) or small interfering RNA (siRNA) against PKCδ. GLUT1/4 inhibition also blocked α1-AR-mediated protection from apoptosis. The PKC inhibitor rottlerin or siRNA against PKCδ blocked α1-AR stimulated GLUT1 or GLUT4 plasma membrane translocation. α1-AR stimulation increased plasma membrane concentration of either GLUT1 or GLUT4 in a time-dependent fashion. Transgenic mice overexpressing the α1A-AR but not α1B-AR mice displayed increased glucose uptake and increased GLUT1 and GLUT4 plasma membrane translocation in the adult heart while α1A-AR but not α1B-AR knockout mice displayed lowered glucose uptake and GLUT translocation. Our results suggest that α1-AR activation is anti-apoptotic and protective during cardiac ischemia due to glucose deprivation and not hypoxia by enhancing glucose uptake into the heart via PKCδ-mediated GLUT translocation that may be specific to the α1A-AR subtype.

    ABSTRACT: Lung cancer is becoming the leading cause of cancer death worldwide with highest morbidity and mortality, and knowing the pathogenesis and signaling pathway is very important and advances in the diagnosis and treatment of the disease are urgently needed. Gene polymorphism was reported to be associated with the lung cancer risk. We reviewed the potential signaling pathway of hypoxia-inducible factor in lung cancer and conducted a meta-analysis to explore its gene polymorphism with lung cancer risk. In the meta-analysis, hypoxia-inducible factor-1α (HIF-1α) G1790A A allele, AA genotype and GG genotype were associated with lung cancer risk (A allele: OR = 2.31, 95% CI: 1.77–3.02, p < 0.00001; AA genotype: OR = 4.52, 95% CI: 2.31–8.83, p < 0.0001; GG genotype: OR = 0.45, 95% CI: 0.33–0.63, p < 0.00001). Furthermore, HIF-1α C1772 TT genotype and CC genotype were associated with lung cancer risk, but the T allele was not. In conclusion, HIF-1α G1790A A allele, AA genotype and GG genotype, HIF-1α C1772 TT genotype and CC genotype were associated with lung cancer risk. However, more studies should be performed to confirm it.

    ABSTRACT: Background: Carnosol is an ortho-diphenolic diterpene with excellent antioxidant potential. The present study was designed to identify the protective role of carnosol against spinal cord injury (SCI)-induced oxidative stress and inflammation in Wistar rats. Methods: In the present study, oxidative stress status was determined through estimating total antioxidant capacity, total oxidant status, lipid peroxide content, protein carbonyl and sulfhydryl levels, reactive oxygen species (ROS), antioxidant status (superoxide-dismutase, catalase, glutathione, glutathione peroxidase, glutathione-S-transferase). Inflammatory effects were determined by analyzing the expression of NF-κB and COX-2 through Western blot analysis. Further, carnosol-mediated redox homeostasis was analyzed by determining p-AKT and Nrf-2 levels. Results: SCI resulted in a significant increase in oxidative stress status through increased ROS generation, total oxidant levels, lipid peroxide content, protein carbonyl and sulfhydryl levels. The antioxidant status in SCI rats was significantly reduced, indicating imbalance in redox status. In addition, the expression of NF-κB and COX-2 was significantly upregulated, while p-AKT and Nrf-2 levels were downregulated in SCI rats. However, treatment with carnosol showed a significant enhancement in the antioxidant status with concomitant decline in oxidative stress parameters. Further, carnosol treatment regulated the key proteins in inflammation and redox status through significant downregulation of NF-κB and COX-2 levels and upregulation of p-AKT and Nrf-2 expression. Conclusion: Thus, the present study shows for the first time on the protective role of carnosol against SCI-induced oxidative stress and inflammation through modulating NF-κB, COX-2 and Nrf-2 levels in Wistar rats.

    ABSTRACT: With the purpose of designing novel chemical entities with improved inhibitory potencies against drug-resistant Mycobacterium tuberculosis, the 3D- quantitative structure–activity relationship (QSAR) studies were carried out on biphenyl analogs of the tuberculosis (TB) drug, PA-824. Anti-mycobacterial activity (MABA) was considered for the 3D-QSAR studies using the comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA) approaches. The best CoMFA and CoMSIA models were found statistically significant with cross-validated coefficients (q2) of 0.784 and 0.768, respectively, and conventional coefficients (r2) of 0.823 and 0.981, respectively. The cross-validated and the external validation results revealed that both the CoMFA and CoMSIA models possesses high accommodating capacities and they would be reliable for predicting the pMIC values of new PA-824 derivatives. Based on the models and structural insights, a series of new PA-824 derivatives were designed and the anti-mycobacterial activities of the designed compounds were predicted based on the best 3D-QSAR model. The predicted data results suggest the designed compounds are more potent than existed ones.

    ABSTRACT: Metabolic homeostasis during long-term adaptation in animals is primarily achieved by controlling the expression of metabolic genes by a plethora of cellular transcription factors. The nuclear receptor superfamily in eukaryotes is an assembly of diverse receptors working as transcriptional regulators of multiple genes. The orphan estrogen-related receptor alpha (ERRα) is one such receptor of the nuclear receptor superfamily with significant influence on numerous metabolic and other genes. Although it is presently unknown as to which endogenous hormones or ligands activate ERRα, nevertheless it regulates a host of genes whose products participate in various metabolic pathways. Studies over the years show new and interesting data that add to the growing knowledge on ERRα and metabolic regulation. For instance, novel findings indicate existence of mTOR/ERRα regulatory axis and also that ERRα control PGC-1α expression which potentially have significant impact on cellular metabolism. Data show that ERRα exerts its metabolic control by regulating the expression of SIRT5 that influence oxygen consumption and ATP generation. Moreover ERRα has a role in creatine and lactate uptake in skeletal muscle which is important towards energy generation and contraction. This review is focused on the new insights gained into ERRα regulation of metabolism and networks and pathways that have important consequences in maintaining metabolic homeostasis including development of cancer.

    ABSTRACT: Abstract Toll-like receptors (TLRs) play a pivotal role in both innate and adaptive immunity, and TLRs recognize invading pathogens through molecular pattern recognition, and ultimately lead to the activation of transcription factors and inflammatory responses. Myocardial infarction leads to changes in the remodeling of the left ventricle of the heart, and the degree and type of remodeling provides important diagnostic information for the therapeutic management of ischemic heart disease. Innate immune takes a most important role in myocardial infarction. There are some studies reporting that TLRs play an important role in the myocardial infarction. The literatures were searched extensively and this review was performed to review the role of TLRs in myocardial infarction.

    ABSTRACT: Abstract GNE Myopathy (GNEM) is a neuromuscular disorder caused by mutations in the GNE gene. It is a slowly progressive distal and proximal muscle weakness sparing the quadriceps. In this study, we applied our model of mutated M743T GNE enzyme skeletal muscle-cultured myoblasts and paired healthy controls to depict the pattern of signaling proteins controlling survival and/or apoptosis of the PI3K/AKT, BCL2, ARTS/XIAP pathways, examined the effects of metabolic changes/stimuli on their expression and activation, and their potential role in GNEM. Immunoblot analysis of the GNEM myoblasts indicated a notable increased level of activated PTEN and PDK1 and a trend of relative differences in the expression and activation of the examined signaling molecules with variability among the cultures. ANOVA analysis showed a highly significant interaction between the level of PTEN and the patients groups. In parallel, the interaction between the level of BCL2, BAX and PTEN with the specific PI3K/AKT inhibitor-LY294002 was highly significant for BCL2 and nearly significant for PTEN and BAX. The pattern of the ARTS/XIAP signaling proteins of GNEM and the paired controls was variable, with no significant differences between the two cell types. The response of the GNEM cells to the metabolic changes/stimuli: serum depletion and insulin challenge, as indicated by expression of selected signaling proteins, was variable and similar to the control cells. Taken together, our observations provide a clearer insight into specific signaling molecules influencing growth and survival of GNEM muscle cells.

    ABSTRACT: Abstract IL-27 plays an important role in anti-cancer activity. The -964A/G polymorphism in IL-27 gene has been implicated in susceptibility to cancer, but the results were conflicting. The aim of this study was to assess the association between this polymorphism and cancer risk. Pubmed and Wanfang database were searched for all publications concerning IL-27 -964A/G polymorphism and cancer risk. Odds ratio (OR) and 95% confidence interval (CI) were used to assess the strength of association. Statistical analysis was performed using Stata 11.0 software. A total of eight case-control studies including 2044 cancer cases and 2197 controls were identified. Overall, significant association between IL-27 -964A/G polymorphism and cancer risk was observed (GG versus AA: OR = 1.26, 95% CI = 1.03-1.52; GG versus AG + AA: OR = 1.20, 95% CI = 1.00-1.44). In subgroup analysis based on cancer type, significant association was found in colorectal cancer (GG versus AA: OR = 1.55, 95% CI = 1.07-2.27; AG versus AA: OR = 1.31, 95% CI = 1.02-1.67). The current meta-analysis suggests that IL-27 -964A/G polymorphism might enhance cancer risk. However, large-scale and well-designed studies are still needed to confirm the result of our meta-analysis. The association of IL-27 polymorphism with colorectal cancer may provide insight for future therapies.
