    ABSTRACT: Chronic granulomatous disease (CGD) is a primary immunodeficiency disorder caused by inherited defects in the NADPH oxidase complex which may be involved in important pathways that connect innate and adaptive immunity. Characterize the naive and memory compartment of B and T lymphocytes in patients with CGD. Twenty CGD patients and twenty healthy controls matched for age and sex were enrolled in this study. Flow cytometric assessment of the naïve and memory compartments of peripheral blood lymphocytes was done using cell surface markers CD45RO, CD45RA, CD27, CD3 and CD19. There were 15 (79%) autosomal recessive CGD patients (8 females (53%) and 7 males (47%), 100% positive parental consanguinity) and four (21%) X-linked CGD patients. On comparing the 3 groups; AR CGD, X-linked CGD and controls, there was a positive statistical significant difference for the percentage and absolute count of CD19 + CD27+ memory B cell (p = 0.028 and p = 0.047 respectively), CD45RA cells (with p values of p = 0.000 and 0.033, respectively), the naïve compartment CD3 + CD45RA+ cells percentage and absolute counts (p = 0.005, 0.01respectively), CD3 + CD27 + cells percentage and absolute counts (p = 0.001, 0.012 respectively), CD3 + CD45RA + CD27+ cells percentage and absolute counts (p = 0.015, 0.005, respectively). The significance was mainly attributed to the decrease in the X-linked group than control group. There was an altered naïve and memory B profile in CGD patients, this may increase susceptibility of the patients to opportunistic infections and autoimmune disorders. T-cell alterations have to be interpreted cautiously especially in the presence of infections.

    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 Tripartite motif 22 (TRIM22) is involved in various cellular processes. It has been reported that TRIM22 can activate nuclear factor-κB (NF-κB) pathway, but the precise mechanism remains unclear. In this study, we explored the exact role of TRIM22 in activating the NF-κB pathway. Different to tumor necrosis factor-α (TNF-α) induction, we found that the overexpression of TRIM22 could induce the processing of p100 to p52 in HEK293T cells. Furthermore, based on the results of co-immunoprecipitation and co-localization experiments, we demonstrated that TRIM22 could interact with IκB kinase (IKK)α but not IKKβ and could increase the level and phosphorylation of IKKα through its really interesting new gene (RING) and spla-ryanodine receptor (SPRY) domains. These results suggest that TRIM22 is able to activate the noncanonical but not the canonical NF-κB pathway by activating IKKα. This finding will aid our understanding of the biological function of TRIM22.

    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.

    ABSTRACT: Abstract Stromal cell-derived factor 1 (CXCL12) and its receptor CXC chemokine receptor 4 (CXCR4) are known to modulate hypoxia-induced pulmonary hypertension (PH) and vascular remodeling by mobilization and recruitment of progenitor cells to the pulmonary vasculature. However, little is known about CXCL12/CXCR4 regulating proliferation and cell cycle progression of pulmonary arterial smooth muscle cells (PASMCs). To determine whether CXCL12/CXCR4 regulates PASMC proliferation and the cell cycle, immunohistochemistry, Western blot, bromodeoxyuridine incorporation and cell cycle analysis were preformed in this study. Our results showed that CXCR4 was induced by hypoxia in pulmonary arteries and PASMCs of rats. Hypoxia-increased cell viability, DNA synthesis and proliferating cell nuclear antigen expression were blocked by administration of CXCR4 antagonist AMD3100, silencing CXCR4 or CXCL12. Furthermore, inhibition of CXCL12/CXCR4 suppressed cell cycle progression, decreased the number of cells in S+G2/M phase and attenuated the expression of proteins that regulate the cell cycle progression at these phases. In addition, PI3K/Akt signaling mediated CXCL12/CXCR4 regulating proliferation and cell cycle progression in PASMCs. Thus, these results indicate that blockade of CXCL12/CXCR4 inhibited PASMC proliferation and cell cycle progression in hypoxia-induced PH via PI3K/Akt signaling pathway.

    ABSTRACT: Abstract Hepatic fibrosis is overly exuberant wound healing in which excessive connective tissue builds up in the liver. The treatment of hepatic fibrosis is still difficult and remains a challenge to the clinician. In recent years, the TGF-β signaling pathway regulator tyrosine kinase Abl has been raised as a new and promising target of hepatic fibrosis therapy. Here, considering that there are numerous drugs and drug-like compounds being approved or under clinical development and experimental investigation, it is expected that some of the existing drugs can be re-exploited as new agents to target Abl with the capability of suppressing hepatic fibrosis. To achieve this, a synthetic protocol that integrated molecular docking, affinity scoring dynamics simulation and free energy analysis was described to systematically profile the inhibitory potency of various drugs and drug-like compounds against the kinase domain of Abl. Consequently, 4 out of 13 tested drug candidates were successfully identified to have high-Abl inhibitory activities. By visually examining the dynamics behavior, structural basis and energetic property of few typical Abl-drug complex cases, a significantly different pattern of non-bonded interactions between the binding of active and inactive drug ligands to Abl receptor was revealed; the former is defined by strong, specific chemical forces, while the latter can only form non-specific hydrophobic contacts with slight atomic collisions.

    ABSTRACT: Abstract Introduction: Bile acids are recognized as signaling molecules, mediating their effects both through the cell surface receptor TGR5 and the nuclear receptor FXR. After a meal, approximately 95% of the bile acids are transported from terminal ileum and back to the liver via the portal vein, resulting in postprandial elevations of bile acids in blood. During the digestion of fat, components from the microbiota, including LPS, are thought to reach the circulation where it may lead to inflammatory responses after binding TLR4 immune cells. Both LPS and bile acids are present in blood after a high-fat meal; we therefore wanted to study consequences of a possible interplay between TGR5 and TLR4 in human monocytes. Methods: The monocytic cell line U937 stably transfected with the NF-κB reporter plasmid 3x-κB-luc was used as a model system to study the effects of TGR5 and TLR4. Activation of MAP kinases was studied to reveal functional consequences of triggering TGR5 in U937 cells. Effects of TGR5 and TLR4 activation were monitored using NF-κB luciferase assay and by quantification of the pro-inflammatory cytokines IL-6 and IL-8 using ELISA. Results: In this study, results show that triggering TGR5 with the specific agonist betulinic acid (BA), and the bile acids CDCA or DCA, activated both the main MAP kinases ERK1/2, p38 and JNK, and the NF-κB signaling pathway. We further demonstrated that co-triggering of TLR4 and TGR5 enhanced the activation of NF-κB and the release of inflammatory cytokines in a synergistic manner compared to triggering of TLR4 alone. Conclusions: Thus, two different and simultaneous events associated with the digestive process coordinately affect the function of human monocytes and contribute to enhanced inflammation. Because elevated levels of circulatory LPS may contribute to the development of insulin resistance, the results from this study suggest that bile acids through the activation of TGR5 may have a role in the development of insulin resistance as well.

    ABSTRACT: The first account on the dynamic features of Nef or negative factor, a small myristoylated protein located in the cytoplasm believes to increase HIV-1 viral titer level, is reported herein. Due to its major role in HIV-1 pathogenicity, Nef protein is considered an emerging target in anti-HIV drug design and discovery process. In this study, comparative long-range all-atom molecular dynamics simulations were employed for apo and bound protein to unveil molecular mechanism of HIV-Nef dimerization and inhibition. Results clearly revealed that B9, a newly discovered Nef inhibitor, binds at the dimeric interface of Nef protein and caused significant separation between orthogonally opposed residues, namely Asp108, Leu112 and Gln104. Large differences in magnitudes were observed in the radius of gyration (∼1.5 Å), per-residue fluctuation (∼2 Å), C-alpha deviations (∼2 Å) which confirm a comparatively more flexible nature of apo conformation due to rapid dimeric association. Compared to the bound conformer, a more globally correlated motion in case of apo structure of HIV-Nef confirms the process of dimeric association. This clearly highlights the process of inhibition as a result of ligand binding. The difference in principal component analysis (PCA) scatter plot and per-residue mobility plot across first two normal modes further justifies the same findings. The in-depth dynamic analyses of Nef protein presented in this report would serve crucial in understanding its function and inhibition mechanisms. Information on inhibitor binding mode would also assist in designing of potential inhibitors against this important HIV target.

    ABSTRACT: Abstract Luffa acutangula (Cucurbitaceae) is widely used as a traditional medicine in India and was reported to possess various pharmacological activities including its anti-proliferative effects. In this study, the bioactive compound of ethanolic extract of L. acutangula (LA) was isolated using bioassay-guided approach. Five major fractions were collected and evaluated for their anti-proliferative activity against non-small cell lung cancer cells (NCI-H460). Among the test fractions, the fraction LA/FII effectively decreased the growth of cancer cells with IC50 values of 10 µg/ml concentration. Furthermore, it significantly increased intracellular reactive oxygen species and decreased the mitochondrial membrane potential. The apoptogenic activity of fraction LA/FII was confirmed by cell shrinkage, membrane blebbing and formation of apoptotic bodies. A single bioactive compound was isolated from the active faction, LA/FII and subsequently identified as 1,8 dihydroxy-4-methylanthracene 9,10-dione (compound 1) by comparing its spectral data [Ultraviolet (UV), Infrared (IR), Nuclear magnetic resonance (NMR) and Electrospray Ionization-Mass Spectroscopy (ESI-MS)] with literature values. This is the first report on the isolation of compound 1 from this plant.

    ABSTRACT: The enzyme complex IκB kinase (IKK) is an essential activator of NF-κB signaling pathway involved in propagating the cellular response to inflammation. The complex contains two functional subunits IKKα and IKKβ, which are structurally conserved kinases and selective inhibition of them would result in distinct biological effects. However, most existing IKK inhibitors show moderate or high promiscuity for the two homologous kinases. Understanding of the molecular mechanism and biological implication underlying the specific interactions in IKK–ligand recognition is thus fundamentally important for the rational design of selective IKK inhibitors. In the current work, we integrated molecular docking, quantum mechanics/molecular mechanics calculation and Poisson–Boltzmann/surface area analysis to investigate the structural basis and energetic property of the selective binding of small-molecule ligands to IKKα and IKKβ. It was found that the selectivity is primarily determined by the size and topology difference in ATP-binding pocket of IKKα and IKKβ kinase domains; bulky inhibitor molecules commonly have, respectively, low and appropriate affinities towards IKKα and IKKβ, and thus exhibit relatively high selectivity for IKKβ over IKKα, whereas small ligands can only bind weakly to both the two kinases with low selectivity. In addition, the conformation, arrangement and distribution of residues in IKK pockets are also responsible for constituting the exquisite specificity of ligand binding to KKα and IKKβ. Next, a novel quantitative structure–selectivity relationship model was developed to characterize the relative contribution of each kinase residue to inhibitor selectivity and to predict the selectivity and specificity for a number of known IKK inhibitors. Results showed that the active-site residues contribute significantly to the selectivity by directly interacting with inhibitor ligands, while those protein portions far away from the kinase active sites may also play an important role in determining the selectivity through long-range non-bonded forces and indirect allosteric effect.

    ABSTRACT: Abstract MicroRNA (miRNA) is a class of small endogenous non-coding RNAs that are ∼ 22 nucleotides in length and can have structural, enzymatic and post-transcriptional regulators of gene expression targeting mRNA for translational repression and/or degradation. miR-497 is high on the list of noncoding, small, regulatory RNAs that plays important roles in the pathogenesis of some diseases and takes part in some signaling pathways in some diseases, but many questions await answers. Vascular endothelial growth factor (VEGF) is a notable chemokine that plays critical roles in angiogenesis and vasculogenesis. There might be an association between miRNA-497 and VEGF. This review was performed to sum up the roles of miR-497 and its potential signaling pathway in diseases and with VEGF.

    ABSTRACT: High-mobility group box-1 protein (HMGB1) is a highly conserved non-histone DNA-binding protein present in the nuclei and cytoplasm of nearly all cell types. The results from recent research provide evidence that HMGB1 is secreted into the extracellular milieu and acts as a pro-inflammatory cytokine and exhibits angiogenic effects to fire the immunological response against the pathological effects. Recently, a great deal of evidence has indicated the critical importance of HMGB1 in mediating vascular barriers dysfunction by modulating the expression of adhesion molecules, such as intercellular adhesion molecule-1, vascular cell adhesion protein 1 and E-selectin on the surface of endothelial cells. Such process promotes the adhesion and migration of leukocytes across the endothelium, leading to breakdown of vascular barriers (blood–brain barrier and blood–retinal barrier) via modulating the expression, content, phosphorylation, and distribution of tight junction proteins. Therefore, here we give an abridged review to understand the mechanistic link between HMGB1 and vascular barriers dysfunction, including interaction with cell-surface receptors and intracellular signaling pathways.

    ABSTRACT: Abstract Peroxisome proliferator-activated receptorγ (PPARγ) can regulate the process of cell apoptosis and is related to the progression of renal disorders. Retinoic acid receptor alpha (RARα) is one of the nuclear receptors involved in a variety of kidney diseases. Renal interstitial fibrosis (RIF) is a common denominator of chronic kidney disease (CKD). This study investigated whether a potential signaling pathway existed between PPARγ and RARα in RIF rats with unilateral ureteral obstruction (UUO). The rats were randomly divided into four groups: a model group subjected to UUO (GU), and three other groups treated with rosiglitazone sodium (GRS), GW9662 and dimethyl sulfoxide (DMSO), n = 40, respectively. Renal tissues were collected two and four weeks after post-surgery. The relevant indicators were detected. In comparison with the GU group, the expressions of PPARγ and RARα (protein and mRNA) were increased in the GRS group, and decreased in the GW9662 group (all p < 0.01). The RIF index, mRNA and protein expression of transforming growth factor-β1 (TGF-β1), and the protein expressions of collagen-IV (Col-IV) and fibronectin (FN) in the GRS group were more markedly reduced than those in the GU group; their levels in the GW9662 group were elevated (all p < 0.01). PPARγ or RARα was negatively correlated to the RIF index, TGF-β1, Col-IV and FN. PPARγ was positively correlated with RARα (all p < 0.01). In conclusion, PPARγ agonist can elevate the expression of PPARγ or RARα in RIF rats. There might be a potential signaling pathway between PPARγ and RARα in RIF disease.

    ABSTRACT: Context: G protein-coupled receptors are vital macromolecules for a wide variety of physiological processes. Upon agonist binding, these receptors accelerate the exchange of GDP for GTP in G proteins coupled to them. The activated G protein interacts with effector proteins to implement downstream biological functions. Objective: We present a kinetic, quaternary complex model, based on a system of coupled linear first-order differential equations, which accounts for the binding attributes of the ligand, receptor, G protein and two types of guanine nucleotide (GDP and GTP) as well as for GTPase activity. Methods: We solved the model numerically to predict the extents of G protein activation, receptor occupancy by ligand and receptor coupling that result from varying the ligand concentration, presence of GDP and/or GTP, the ratio of G protein to receptor and the equilibrium constants governing receptor pre-coupling and constitutive activity. We also simulated responses downstream from G protein activation using a transducer function. Results: Our model shows that agonist-induced G protein activation can occur with either a net decrease or increase in total receptor-G protein coupling. In addition, we demonstrate that affinity constants of the ligand for both the active and inactive states of the receptor can be derived to a close approximation from analysis of simulated responses downstream from receptor activation. Discussion and conclusion: The latter result validates our prior methods for estimating the active state affinity constants of ligands, and our results on receptor coupling have relevance to studies investigating receptor-G protein interactions using fluorescence techniques.

    ABSTRACT: Abstract Objective: To better understand the risks of rheumatoid arthritis (RA) and certain subsets conferred by mannose-binding lectin (MBL2) polymorphisms in different races. Materials and methods: Eighteen articles (4810 cases and 4585 controls) were identified from the latest literature search carried out in May 2014 using PubMed, Web of Science, Wanfang Database (Chinese) and Chinese National Knowledge Infrastructure. Three single nucleotide polymorphisms of codon 52, 54 and 57, exonic and extended genotypic variance in MBL2 were synthesized. Results: Codon 54 mutation of MBL2 was unlikely to be a risk factor for RA in overall population, but turned out to be deleterious in East Asian (four studies with 523 cases and 647 controls, pooled OR:1.63, 95% CI: 1.23-2.17). Codon 54 mutation increased the risk of seropositive and erosive RA by 44% and 162%, respectively (three studies with 281 cases and 358 controls, 95% CI: 1.01-2.05; 3 studies with 180 cases and 499 controls, 95% CI: 1.77-3.88). Furthermore, those risks were relatively stronger when restricted in East Asian (two studies with 147 cases and 244 controls, pooled OR: 1.85, 95% CI: 1.19-2.87; 2 studies with 170 cases and 291 controls, pooled OR: 2.78, 95% CI: 1.85-4.20). No remarkable associations were detected regarding codon 52, 57, exon 1 and extended genotype of MBL2. Conclusions: Polymorphism of codon 54 in MBL2 may predispose to RA, especially seropositive or erosive RA, which East Asian appears to be more vulnerable.
