Pathogenesis of Diabetic Cardiomyopathy and Role of miRNA.

Diabetic cardiomyopathy is characterized as abnormal function and structure of myocardium associated with diabetes irrespective of other cardiac risk factors like hypertension or coronary artery disease (CAD). The pathogenesis of DCM was not well understood in the past due to its complexity but it has been discovered recently. Various factors are found to be associated with the onset of DCM including impaired calcium handling, remodeling of extracellular matrix (ECM), increased oxidative stress, altered metabolism, mitochondrial dysfunction, and endothelial dysfunction. Micro-RNAs (miRNAs) are also found to be of great importance in the pathogenesis of DCM. Different miRNAs like miR-126, miR-24, miR-1, miR-155, miR-499, and miR-199a are found to be associated with different types of heart diseases like CAD and myocardial infarction. Studies have shown that the miRNA plays a crucial role in the development of DCM and it was found that the expression levels of different miRNAs differ in patients as compared to healthy individuals. This review focuses on the pathogenesis of DCM and various factors involved in the onset of diabetic car-diomyopathy. Moreover, the probable role of miRNA in the pathogenesis of DCM is also discussed.

Conserved B and T cell epitopes prediction of ebola virus glycoprotein for vaccine development: An immuno-informatics approach.

Ebola virus (EBOV), a non-segmented single-stranded RNA virus, is often-most transmitted through body fluids like sweat, tears, saliva, and nasal secretions. Till date, there is no licensed vaccine of EBOV is available in the market; however, the world is increasingly vulnerable to this emerging threat. Hence, it is the need of time to develop a vaccine for EBOV to hinder its dissemination. The current study has been designed for identification and characterization of the potential B and T-cell epitopes using the Immuno-informatics tools, and it helped in finding the potent vaccine candidates against EBOV. Prediction, antigenicity and allergenicity testing of predicted B and T cells' epitopes was done as well to identify their potential as a vaccine candidate and to measure their safety level respectively. Among B-cell epitopes "WIPAGIGVTGVIIA" showed a high antigenicity score and it would play an important role in evoking the immune response. In T-cell epitopes, peptides "AIGLAWIPY" and "IRGFPRCRY" presented high antigenicity score, which binds to MHC class-I and MHC class-II alleles respectively. All predicted epitopes were analyzed and compared with already reported peptides carefully. Comparatively, Peptides predicted in the present study showed more immunogenicity score than already reported peptides, used as positive control, and are more immunogenic as compared to them. Peptides reported in the present study do not target only Zaire EBOV (ZEBOV), as in previous studies, but also other species, i.e. Tai Forest EBOV (TAFV), Sudan EBOV (SUDV), Bundibugyo EBOV (BDBV), and Reston EBOV (RESTV) and would bring the promising results as potent vaccine candidates.

Study on structural insight of the analysis of negative effects of opioids analgesics in naltrexone with TLR4 Mutations.

Chronic pain has been defined as the persistence that remained for more than three months. The extent of previous time duration with the normal time of natural healing phase becomes poor and results in reduced life quality and morbidity. Opioids are well recognized therapy for pain management and the clinical prescriptions based on opioids have been defined with increasing implicating behavior among patients suffering with chronic pain. The association between the pain and immunity has long been established since the involvement of interleukin-1ß (IL-1ß) in sickness that is considered with the induced hyperalgesia. In the context of pharmacodynamics Toll like receptors (TLRs) are involved in the negative effects of opioids as analgesics. The soluble factors released by immune cells as well as from the disruptive cells bind to TLRs. This binding leads the pre and post-synaptic ends on endothelial and microglial cells that exhibit the activation of complex inhibitory and excitatory process at the synapses site. In TLRs, TLR4 is mostly reported that is strongly associated in specifically in areas of T cells and macrophages. The current study is designed to investigate the structural insights of the opioids and TLR4 interactions by using computational approach in the aspect of recognizing the chemical combinatorial factors that are involved in the pain management. This study targets that how opioids interact with TLR4 and the process of chemical interaction that leads to negative effects of opioids at neuroimmune interface as well as to investigate the extent of particular naltrexone that mediates with the negative effects of opioids.

Computational screening of phytochemicals against survivin protein: A potent target for cancer.

Survivin (IAP proteins) is considered as a significant target for anticancer drug research owing to its upregulation in tumor cells to mediate resistance to apoptotic stimulus. The current study aimed to investigate phytochemicals as inhibitors of survivin with caspases to reactivate the functioning of caspases through molecular docking. The compounds namely 2(R), 4(R)-dihydroxypyrrolidine, 4-hydroxy-2-(4-methoxyphenyl)-1,1-dioxo-3,4-dihydrothieno[3,2-e]thiazine-6-sulfonamide, 2,3-Diketo-L-gulonic acid, (3-hydroxy-2-octadeca-9,12-dienoyloxypropyl) octadecanoate, 2-[[4-[[4-[(4-formamido-1-methylimidazole-2-carbonyl)amino]-1-methylimidazole-2-carbonyl]amino]-1-methylimidazole-2-carbonyl]amino]ethyl-dimethylazanium, Picolinic acid and (2-Hydroxy-5-nitrophenyl) dihydrogen phosphate successfully bind inside the pocket of survivin. ADMETsar was used to evaluate the anticancer potential of selected compounds. These compounds can be proposed as effective inhibitors, disrupting the survivin-caspases interaction and reactivating the caspases function of apoptosis. The study might facilitate the development of cost-effective and natural drugs against cancer. However, further validation is essential for confirmation of its drug efficacy and bio-compatibility.

Interferon-Free Regimen for Hepatitis C: Insight and Management.

The rapid development of direct-acting antiviral agents (DAA) for hepatitis C virus (HCV) therapy dramatically altered the treatment landscape of this disease. The DAA regimen is associated with various advantages including high sustained virological response (SVR) with minimum side effects and low pill load and specific inhibition of viral replication, which lowers dependence on the host cell. This regimen has substantially replaced conventional (interferon) therapy with high cure rates (> 90%) in most HCV populations. This review provides insight into clinical studies of NS3/4A protease inhibitors, NS5B viral polymerase inhibitor (nucleotide and non-nucleotide), and NS5A inhibitors, alone and in combination.

Potential of Stem Cells as Regenerative Medicine: From Preface to Advancements.

Regenerative medicine is an emerging field to find solutions to some of the most challenging medical problems of humans. Regenerative medicine has the potential to revolutionize the whole health care system, in dealing with conditions such as heart disease, emphysema, liver fibrosis, kidney disease, diabetes, and neurological disorders. Among the many challenges to bringing regenerative medicine to the clinic is the selection of the best cell types and reliable ways to expand the number of cells. Stem cells emerged as the best cell type for regeneration of different organs. This review covers the application of stem cells in different degenerative diseases.

Genetically Modified Aedes aegypti to Control Dengue: A Review.

Dengue is an acute infectious disease of viral etiology characterized by lymphadenopathy, leucopenia, headache, biphasic fever, pain in various parts of the body, rashes, and extreme physical weakness. It is a vector-borne disease caused by a positive-stranded RNA virus of the family Flaviviridae, genus Flavivirus. Dengue inflicts a significant health, economic, and social burden on populations of endemic areas. Dengue virus is transmitted to humans by the mosquito vector Aedes aegypti. Vaccines against dengue viruses have been claimed to be developed, but as yet no effective treatment is available. Alternative therapeutic strategies to overcome this disease and its spread are direly needed. A traditional sterile insect technique (SIT) harms the health of male insects, leading to their reduced ability to compete for wild-type female insects for breeding. Oxitec (Abingdon, UK) has developed genetically modified (GM) strains of A. aegypti via the release of insects carrying a dominant lethal (RIDL) strategy. RIDL male mosquitoes offer a resolution to many of the limitations of traditional SIT, which has resulted in reduced application of SIT in mosquitoes. The technique using RIDL mosquitoes is considered to be ecologically friendly and specific. Homing endonuclease genes, also called selfish genes, can also be used in genetic modification methods in such a way that the vector population and its competency can be reduced. GM mosquitoes carrying a gene that transcribes RNA interference can also be crucial to control expression of RNA viruses. The RNA virus interference pathway is one of the most critical components of the innate immune system of insects that can frustrate a variety of RNA viruses such as Flaviviruses. Here, we summarize and focus on alternative techniques used to control dengue spread.

Designing and molecular docking of cyclic peptides against HCV NS3 protease.

Hepatitis C Virus (HCV) infection is a worldwide serious health issue which contributes towards most of the hepatic morbidities. So far no prophylaxis is available to prevent this virus; therefore, development of antiviral compounds to fight HCV infection is the need of time. Chemically synthesized peptides that are potent immunogenic antigens are being pursued as candidate vaccines against HCV. The present study was planned to identify peptide inhibitors having potential to block the activity of NS3 protein of HCV that will ultimately arrest HCV multiplication. Docking of NS3 with peptides revealed that the majority of the peptides have strong binding affinity for active sites of NS3. Peptide 1, 2, 3 and 6 were found interactive with NS3 active residues while the active sites of NS3 had hydrophobic contact with the rest of peptides. Thus, these peptides bear therapeutic potential of a candidate drug for the prevention of HCV replication. Post docking analysis revealed important binding abilities of peptides with the active sites of NS3 protein, showing the efficiency of peptides as potential peptide inhibitors against HCV. The study revealed that HCV replication can be inhibited by these peptides. HCV replication inhibition potential of these peptides can contribute in reducing the burden of HCV infection and its associated complications worldwide.

Relationship of oxidative stress with elevated level of DNA damage and homocysteine in cardiovascular disease patients.

Amounts of DNA damage and homocysteine (Hcy) in heart patients blood may have strong function in the causation of cardiovascular disease (CVD). The main objective of this work was to know experimentally the role of total oxidants (produced by Reactive Oxygen species (ROS), clinical biochemical indices, their oxidized products and total antioxidant status (TAS) among such patients to find the association of homocysteine, total oxidation status (TOS) and oxidative DNA damage with other clinical parameters in sixty positive CVD patients compared with those of 60 normal subjects. As compared to healthy individuals, CVD patients had significantly higher concentrations of homocysteine (p<0.0001), total oxidants stress (TOS) (p<0.0001), serum total lipids (p<0.04), malondialdehyde (MDA) (p<0.001), high density lipoprotein-cholesterol (HDL-C) (p<0.0001), and low density lipoprotein cholesterol (LDL-C) (p<0.01), than those of healthy individuals. Plasma Hcy content, TOS and amount of DNA were positively and significantly associated with cholesterol, triglycerides, systolic blood pressure, urea, and albumin (p values<0.01). TOS, Hcy and oxidative DNA damage were negatively correlated with HDL-c, TAS and proteins. It is suggested that these parameters have pivotal role in diagnostic process of determining severity in CAD patients. Oxidized products of macromolecules in blood of CVD patients impart major functions in causing CVD disease.

Transcriptional Factors Mediated Reprogramming to Pluripotency.

A unique kind of pluripotent cell, i.e., Induced pluripotent stem cells (iPSCs), now being targeted for iPSC synthesis, are produced by reprogramming animal and human differentiated cells (with no change in genetic makeup for the sake of high efficacy iPSCs formation). The conversion of specific cells to iPSCs has revolutionized stem cell research by making pluripotent cells more controllable for regenerative therapy. For the past 15 years, somatic cell reprogramming to pluripotency with force expression of specified factors has been a fascinating field of biomedical study. For that technological primary viewpoint reprogramming method, a cocktail of four transcription factors (TF) has required: Kruppel-like factor 4 (KLF4), four-octamer binding protein 34 (OCT3/4), MYC and SOX2 (together referred to as OSKM) and host cells. IPS cells have great potential for future tissue replacement treatments because of their ability to self-renew and specialize in all adult cell types, although factor-mediated reprogramming mechanisms are still poorly understood medically. This technique has dramatically improved performance and efficiency, making it more useful in drug discovery, disease remodeling, and regenerative medicine. Moreover, in these four TF cocktails, more than 30 reprogramming combinations were proposed, but for reprogramming effectiveness, only a few numbers have been demonstrated for the somatic cells of humans and mice. Stoichiometry, a combination of reprogramming agents and chromatin remodeling compounds, impacts kinetics, quality, and efficiency in stem cell research.

The antihyperglycemic potential of pyrazolobenzothiazine 1, 1-dioxide novel derivative in mice using integrated molecular pharmacological approach.

Diabetes Mellitus is a metabolic disease characterized by elevated blood sugar levels caused by inadequate insulin production, which subsequently leads to hyperglycemia. This study was aimed to investigate the antidiabetic potential of pyrazolobenzothiazine derivatives in silico, in vitro, and in vivo. Molecular docking of pyrazolobenzothiazine derivatives was performed against α-glucosidase and α-amylase and compounds were selected based on docking score, bonding interactions and low root mean square deviation (RMSD). Enzyme inhibition assay against α-glucosidase and α-amylase was performed in vitro using p-nitrophenyl-α-D-glucopyranoside (PNPG) and starch substrate. Synthetic compound pyrazolobenzothiazine (S1) exhibited minimal conformational changes during the 100 ns MD simulation run. S1 also revealed effective IC50 values for α-glucosidase (3.91 µM) and α-amylase (8.89 µM) and an enzyme kinetic study showed low ki (- 0.186 µM, - 1.267 µM) and ki' (- 0.691 µM, - 1.78 µM) values with the competitive type of inhibition for both enzymes α-glucosidase and α-amylase, respectively. Moreover, studies were conducted to check the effect of the synthetic compound in a mouse model. A low necrosis rate was observed in the liver, kidney, and pancreas through histology analysis performed on mice. Compound S1 also exhibited a good biochemical profile with lower sugar level (110-115 mg/dL), increased insulin level (25-30 µM/L), and low level of cholesterol (85 mg/dL) and creatinine (0.6 mg/dL) in blood. The treated mice group also exhibited a low % of glycated haemoglobin (3%). This study concludes that S1 is a new antidiabetic-agent that helps lower blood glucose levels and minimizes the complications associated with type-II diabetes.

Identification and characterization of codon usage pattern and influencing factors in HFRS-causing hantaviruses.

Hemorrhagic fever with renal syndrome (HFRS) is an acute viral zoonosis carried and transmitted by infected rodents through urine, droppings, or saliva. The etiology of HFRS is complex due to the involvement of viral factors and host immune and genetic factors which hinder the development of potential therapeutic solutions for HFRS. Hantaan virus (HTNV), Dobrava-Belgrade virus (DOBV), Seoul virus (SEOV), and Puumala virus (PUUV) are predominantly found in hantaviral species that cause HFRS in patients. Despite ongoing prevention and control efforts, HFRS remains a serious economic burden worldwide. Furthermore, recent studies reported that the hantavirus nucleocapsid protein is a multi-functional protein and plays a major role in the replication cycle of the hantavirus. However, the precise mechanism of the nucleoproteins in viral pathogenesis is not completely understood. In the framework of the current study, various in silico approaches were employed to identify the factors influencing the codon usage pattern of hantaviral nucleoproteins. Based on the relative synonymous codon usage (RSCU) values, a comparative analysis was performed between HFRS-causing hantavirus and their hosts, suggesting that HTNV, DOBV, SEOV, and PUUV, were inclined to evolve their codon usage patterns that were comparable to those of their hosts. The results indicated that most of the overrepresented codons had AU-endings, which revealed that mutational pressure is the major force shaping codon usage patterns. However, the influence of natural selection and geographical factors cannot be ignored on viral codon usage bias. Further analysis also demonstrated that HFRS causing hantaviruses adapted host-specific codon usage patterns to sustain successful replication and transmission chains within hosts. To our knowledge, no study to date reported the factors influencing the codon usage pattern within hantaviral nucleoproteins. Thus, the proposed computational scheme can help in understanding the underlying mechanism of codon usage patterns in HFRS-causing hantaviruses which lend a helping hand in designing effective anti-HFRS treatments in future. This study, although comprehensive, relies on in silico methods and thus necessitates experimental validation for more solid outcomes. Beyond the identified factors influencing viral behavior, there could be other yet undiscovered influences. These potential factors should be targets for further research to improve HFRS therapeutic strategies.

Systematic elucidation of the multi-target pharmacological mechanism of Terminalia arjuna against congestive cardiac failure via network pharmacology and molecular modelling approaches.

Congestive cardiac failure (CCF) is a pathophysiologic state when the heart is not able to maintain its cardiac output to meet the demand of metabolising tissues. CCF is responsible for approximately 2.9 million deaths worldwide. The heterogeneous nature of CCF draws the attention of researchers to find more enthralling and promising diagnostic and treatment options. Terminalia arjuna (Arjuna) is an evergreen, deciduous tree exhibited various astringent, anti-bacterial, and anti-microbial properties. T. arjuna is being used in various regions for anginal pain, hypertension, congestive heart failure, and dyslipidemia. Although previous in vitro studies have demonstrated the therapeutic potential of T. arjuna, the exact molecular mechanism underlying its protective effect on the heart remains unclear. In this study, a network pharmacology technique was used to explore the active ingredients, potential targets in T. arjuna for the treatment of CCF. In the framework of this study, we explored the active ingredient-target-pathway network and figured out that oleanolic acid, arjunolic acid, luteolin, kaempferol, cholesterol, ellagic acid 4-O-xylopyranoside 3,3'-dimethyl ether, and cyclohexyl (2,4-dimethyl phenyl) methanone contributed significantly to the development of CCF by affecting AKT1, MAPK14, TNF, IL6, ESR1, and HSP90AA1 genes. Molecular docking analysis further validated the activities of these compounds against potential targets. To sum up, integrated network pharmacology and docking analysis revealed that T. arjuna exerts its cardioprotective effect by acting on various signalling pathways, including the thyroid hormone, VEGF signalling pathway, AGE-RAGE signalling pathway in diabetic complications, HIF signalling pathway, sphingolipid signalling pathway, and oestrogen signalling pathways. Overall, this study provides valuable insights into the molecular mechanism of T. arjuna in CCF and highlights its potential as a promising preventive treatment for this condition.

Advanced network pharmacology study reveals multi-pathway and multi-gene regulatory molecular mechanism of Bacopa monnieri in liver cancer based on data mining, molecular modeling, and microarray data analysis.

Liver cancer is a malignant tumor that grows on the surface or inside the liver. The leading cause is a viral infection with hepatitis B or C virus. Natural products and their structural analogues have historically made a major contribution to pharmacotherapy, especially for cancer. A list of studies evidences the therapeutic efficacy of Bacopa monnieri against liver cancer, but the precise molecular mechanism is yet to be discovered. This study combines data mining, network pharmacology, and molecular docking analysis to potentially revolutionize liver cancer treatment by identifying effective phytochemicals. Initially, the information on active constituents of B. monnieri and target genes of both liver cancer and B. monnieri were retrieved from literature as well as from publicly available databases. Based on the matching results between B. monnieri potential targets and liver cancer targets, the protein-protein interaction (PPI) network was constructed using the STRING database and imported into Cytoscape for screening of hub genes based on their degree of connectivity. Later, the interactions network between compounds and overlapping genes was constructed using Cytoscape software to analyze the network pharmacological prospective effects of B. monnieri on liver cancer. Gene Ontology (GO) and KEGG pathway analysis of hub genes revealed that these genes are involved in the cancer-related pathway. Lastly, the expression level of core targets was analyzed using microarray data (GSE39791, GSE76427, GSE22058, GSE87630, and GSE112790). Further, the GEPIA server and PyRx software were used for survival and molecular docking analysis, respectively. In summary, we proposed that quercetin, luteolin, apigenin, catechin, epicatechin, stigmasterol, beta-sitosterol, celastrol, and betulic acid inhibit tumor growth by affecting tumor protein 53 (TP53), interleukin 6 (IL6), RAC-alpha serine/threonine protein kinases 1 (AKT1), caspase-3 (CASP3), tumor necrosis factor (TNF), jun proto-oncogene (JUN), heat shot protein 90 AA1 (HSP90AA1), vascular endothelial growth factor A (VEGFA), epidermal growth factor receptor (EGFR), and SRC proto-oncogene (SRC). Through, microarray data analysis, the expression level of JUN and IL6 were found to be upregulated while the expression level of HSP90AA1 was found to be downregulated. Kaplan-Meier survival analysis indicated that HSP90AA1 and JUN are promising candidate genes that can serve as diagnostic and prognostic biomarkers for liver cancer. Moreover, the molecular docking and molecular dynamic simulation of 60ns well complemented the binding affinity of the compound and revealed strong stability of predicted compounds at the docked site. Calculation of binding free energies using MMPBSA and MMGBSA validated the strong binding affinity between the compound and binding pockets of HSP90AA1 and JUN. Despite that, in vivo and in vitro studies are mandatory to unveil pharmacokinetics and biosafety profiles to completely track the candidature status of B. monnieri in liver cancer.

Pre-conditioned mesenchymal stem cells ameliorate renal ischemic injury in rats by augmented survival and engraftment.

BACKGROUND: Ischemia is the major cause of acute kidney injury (AKI), associated with high mortality and morbidity. Mesenchymal stem cells (MSCs) have multilineage differentiation potential and can be a potent therapeutic option for the cure of AKI. METHODS: MSCs were cultured in four groups SNAP (S-nitroso N-acetyl penicillamine), SNAP + Methylene Blue (MB), MB and a control for in vitro analysis. Cultured MSCs were pre-conditioned with either SNAP (100 µM) or MB (1 µM) or both for 6 hours. Renal ischemia was induced in four groups (as in in vitro study) of rats by clamping the left renal padicle for 45 minutes and then different pre-conditioned stem cells were transplanted. RESULTS: We report that pre-conditioning of MSCs with SNAP enhances their proliferation, survival and engraftment in ischemic kidney. Rat MSCs pre-conditioned with SNAP decreased cell apoptosis and increased proliferation and cytoprotective genes' expression in vitro. Our in vivo data showed enhanced survival and engraftment, proliferation, reduction in fibrosis, significant improvement in renal function and higher expression of pro-survival and pro-angiogenic factors in ischemic renal tissue in SNAP pre-conditioned group of animals. Cytoprotective effects of SNAP pre-conditioning were abrogated by MB, an inhibitor of nitric oxide synthase (NOS) and guanylate cyclase. CONCLUSION: The results of these studies demonstrate that SNAP pre-conditioning might be useful to enhance therapeutic potential of MSCs in attenuating renal ischemia reperfusion injury.

Anti-inflammatory potential of berberine-rich extract via modulation of inflammation biomarkers.

Berberine-rich extract (BRE) prepared from Berberis lycium root bark using green extraction approach and its marker compound berberine has a broad spectrum of clinical applications. Berberine's potential pharmacological effects include anticancer, antidiarrheal, antidiabetic, antimicrobial and anti-inflammatory activities. In current work, BRE and berberine were evaluated for their therapeutic prospects in inflammation models. The comparative effect of BRE and berberine against inflammation was determined through in vitro chemiluminescence technique. The in vivo anti-inflammatory evaluation of BRE and berberine (25, 75, and 125 mg/kg) compared to diclofenac (10 mg/kg) was performed in carrageenan and formaldehyde-induced inflammation in Wistar rats. Histopathological and biochemical studies were conducted to find the comparative anti-inflammatory potential of BRE and berberine on pathological hallmarks induced by formaldehyde. Moreover, the modulatory effects on inflammatory biomarkers were also investigated through qPCR. ELISA (enzyme-linked immunoassay test assay) was performed to investigate the expression of pathological protein biomarkers like TNF-α and IL-6 and levels of antioxidant enzymes were estimated in liver homogenates. Both BRE and berberine markedly (p < .001) reduced paw diameter and inflammation in carrageenan and formaldehyde-induced inflammation. The levels of antioxidant enzymes were recovered (p < .001) by BRE and berberine treatments, and compared to the formaldehyde-treated inflammation model. Both BRE and berberine remarkably downregulated the mRNA and protein expression of inflammatory biomarkers. BRE similar to berberine mitigated the level of antioxidant enzymes in liver homogenate. The undertaken study suggests that BRE, a natural, green, and therapeutically bioequivalent to berberine could be used as an economical phytomedicine in the treatment of inflammatory disorders. PRACTICAL APPLICATIONS: Anti-inflammatory drugs like NSAIDS are associated with serious adverse effects like gastrointestinal ulcer, worsening of preexisting cardiovascular disorders, and renal failure. Therefore, there is a constant demand to develop novel, inexpensive therapeutic strategies to treat the inflammatory disorder with the least harmful effects. Pure phytochemicals with anti-inflammatory potential are costly and hard to isolate, therefore green microwave-assisted extraction technique is developed to get the rich bioequivalent extract. Berberis lycium a medicinal plant with berberine as a major bioactive constituent, has wide acceptance in traditionally used medicine and as food. Pharmacological studies revealed its hepatoprotective, anticancer, antidiabetic, and antihypertensive activities. BRE was prepared by green microwave-assisted extraction and enrichment by resin column to get a higher yield of berberine. The comparative anti-inflammatory effect of BRE and berberine was determined by in vitro and in vivo studies. Results obtained from this experimental work contribute beneficial guidance that reinforces the use of the BRE to treat inflammatory disorders.

Impact of dietary inclusion of Chenopodium quinoa on growth performance and survival of Hubbard chicken.

The poultry sector is the most vibrant segment of the agriculture system plays a vital role in the supply of healthy meat products. Broiler production effectiveness is greatly associated with feed formulation. Although, broiler exhibits a relatively fast growth rate, the nutritional profile of its meat has been criticized under conventional human dietary regimes. In the current study, the dietary inclusion of quinoa was assessed to improve broiler growth performance, carcass quality, and health by analyzing different growth, hematological and biochemical, immunological parameters. In the present study, the chicken was fed with 50 g/kg, 100 g/kg, and 200 g/kg quinoa enriched diets in two different experimental groups during the growth phase or finisher phase while chicken fed with diet without quinoa were as control. The 50 g/kg quinoa supplemented chicken group revealed a substantial difference in growth performance in comparison with the control group. In addition, the examination of quinoa dietary supplementation on carcass quality exhibited variable behavior. Further, all the study groups fed with quinoa during the growth phase revealed no remarkable difference in the hematological profile in contrast to the control group except for the chicken group fed (50 g/Kg) during the finisher phase for hemoglobin levels. Likewise, all the quinoa enriched diet given chicken groups showed no significant difference in serum biochemical profile in contrast to the control group except for the 50 g/Kg quinoa fed chicken group during the finisher phase for total globulin levels. In addition, the examination of quinoa dietary supplementation on the broiler serum lipid profile was also assessed and birds exhibited variable behavior as the result of quinoa dietary supplementation. Evaluation of short-term immune response after quinoa supplementation assessed and birds exhibited no marked significance on expression outcomes of interleukin/cytokines (IL 1 beta, IL-6, IL-10) assessed by qRT-PCR analysis. In conclusion, the dietary supplementation of broiler fed with quinoa seeds can enhance the growth performance and the carcass quality of broiler.

Identification of Pathogenic Mutations in Primary Microcephaly- (MCPH-) Related Three Genes CENPJ, CASK, and MCPH1 in Consanguineous Pakistani Families.

Microcephaly (MCPH) is a developmental anomaly of the brain known by reduced cerebral cortex and underdeveloped intellectual disability without additional clinical symptoms. It is a genetically and clinically heterogenous disorder. Twenty-five genes (involved in spindle positioning, Wnt signaling, centriole biogenesis, DNA repair, microtubule dynamics, cell cycle checkpoints, and transcriptional regulation) causing MCPH have been identified so far. Pakistani population has contributed in the identification of many MCPH genes. WES of three large consanguineous families revealed three pathogenic variants of MCPH1, CENPJ, and CASK. One novel (c.1254delT) deletion variant of MCPH1 and one known (c.18delC) deletion variant of CENPJ were identified in family 1 and 2, respectively. In addition to this, we also identified a missense variant (c.1289G>A) of CASK in males individuals in family 3. Missense mutation in the CASK gene is frequent in the boys with intellectual disability and autistic traits which are the common features that are associated with FG Syndrome 4. The study reports novel and reported mutant alleles disrupting the working of genes vital for normal brain functioning. The findings of this study enhance our understanding about the genetic architecture of primary microcephaly in our local pedigrees and add to the allelic heterogeneity of 3 known MCPH genes. The data generated will help to develop specific strategies to reduce the high incidence rate of MCPH in Pakistani population.

Screening of drug candidates against Endothelin-1 to treat hypertension using computational based approaches: Molecular docking and dynamics simulation.

Hypertension (HTN) is a major risk factor for cardiovascular and renal diseases, cerebrovascular accidents (CVA) and a prime underlying cause of worldwide morbidity and mortality. Hypertension is a complex condition and a strong interplay of multiple genetic, epigenetic and environmental factors is involved in its etiology. Previous studies showed an association of overexpression of genes with hypertension. Satisfactory control of Blood Pressure (BP) levels is not achieved in a major portion of hypertensive patients who take antihypertensive drugs. Since existing antihypertensive drugs have many severe or irreversible side effects and give rise to further complications like frequent micturition and headaches, dizziness, dry irritating cough, hypoglycemia, GI hemorrhage, impaired left ventricular function, hyperkalemia, Anemia, angioedema and azotemia. There is a need to identify new antihypertensive agents that can inhibit the expression of these overexpressed genes contributing to hypertension. The study was designed to identify drug-able targets against overexpressed genes involved in hypertension to intervene the disease. The structure of the protein encoded by an overexpressed gene Endothelin-1 was retrieved from Protein Database (PDB). A library of five thousand phytochemicals was docked against Endothelin-1. The top four hits against Endothelin-1 protein were selected based on S score and Root Mean Square Deviation (RMSD). S score is a molecular docking score which is used to determine the preferred orientation, binding mode, site of the ligand and binding affinity. RMSD refines value for drug target identification. Absorption, distribution, metabolism, excretion, and toxicity profiling (ADMET) was done. The study provides novel insights into HTN etiology and improves our understanding of BP pathophysiology. These findings help to understand the impact of gene expression on BP regulation. This study might be helpful to develop an antihypertensive drug with a better therapeutic profile and least side effects.

Identification and Computational Analysis of Rare Variants of Known Hearing Loss Genes Present in Five Deaf Members of a Pakistani Kindred.

Hearing loss (HL) is the most common neurosensory defect in humans that affects the normal communication. Disease is clinically and genetically heterogeneous, rendering challenges for the molecular diagnosis of affected subjects. This study highlights the phenotypic and genetic complexity of inherited HL in a large consanguineous Pakistan kindred. Audiological evaluation of all affected individuals revealed varying degree of mild to profound sensorineural HL. Whole exome (WES) of four family members followed by Sanger sequencing revealed candidate disease-associated variants in five known deafness genes: GJB2 (c.231G>A; p.(Trp77 *)), SLC26A4 (c.1337A>G; p.(Gln446Arg)), CDH23 (c.2789C>T; p.(Pro930Leu)), KCNQ4 (c.1672G>A; p.(Val558Met)) and MPDZ (c.4124T>C; p.(Val1375Ala)). All identified variants replaced evolutionary conserved residues, were either absent or had low frequencies in the control databases. Our in silico and 3-Dimensional (3D) protein topology analyses support the damaging impact of identified variants on the encoded proteins. However, except for the previously established "pathogenic" and "likely pathogenic" categories for the c.231G>A (p.(Trp77 *)) allele of GJB2 and c.1377A>G (p.(Gln446Arg)) of SLC26A4, respectively, all the remaining identified variants were classified as "uncertain significance" based on the American College of Medical Genetics and Genomics/Association for Molecular Pathology (ACMG/AMP) variant pathogenicity guidelines. Our study highlights the complexity of genetic traits in consanguineous families, and the need of combining the functional studies even with the comprehensive profiling of multiple family members to improve the genetic diagnosis in complex inbred families.
