Both histone modifications and microRNAs (miRNAs) play pivotal role in gene expression regulation. Although numerous studies have been devoted to explore the gene regulation by miRNA and epigenetic regulations, their coordinated actions have not been comprehensively examined. In this work, we systematically investigated the combinatorial relationship between miRNA and epigenetic regulation by taking...
Diabetes mellitus is a heterogeneous metabolic disorder essentially characterized by deficiency of insulin secretion, insulin receptor or post-receptor events. This study aims to investigate the effects of resveratrol administration on the metabolic characteristics, hepatic functions, histopathological features and insulin signaling pathway components in streptozotocin induced diabetes.Male Wistar...
Glaucoma is one of the primary causes of visual impairment and blindness in the world. It is characterized by the damage to the optic nerve head and visual field loss. Variants in CYP1B1 are the most common cause of glaucoma in different world populations. We studied a consanguineous Pakistani family in which three affected individuals had a severe form of glaucoma with members in one generation diagnosed...
The positive regulatory domain containing 16 (PRDM16) is commonly regarded as a “switch” controlling the transdifferentiation of myoblasts to brown adipocytes. The N-positive regulatory (PR) domain, which is highly homologous to SET domain, is a characteristic structure for the PRDM family.Many SET domain containing proteins and several PRDM members have been found to possess histone methyltransferase...
In insect, juvenile hormone (JH) titers are tightly regulated in different development stages through synthesis and degradation pathways. During JH degradation, JH epoxide hydrolase (JHEH) converts JH to JH diol, and hydrolyses JH acid to JH acid diol. In this study, two full length LdJHEH cDNAs were cloned from Leptinotarsa decemlineata, and were provisionally designated LdJHEH1 and LdJHEH2. Both...
The number of annual cannabinoid users exceeds 100,000,000 globally and an estimated 9% of these individuals will suffer from dependency. Although exogenous cannabinoids, like those contained in marijuana, are known to exert their effects by disrupting the endocannabinoid system, a dearth of knowledge exists about the potential toxicological consequences on public health. Conversely, the endocannabinoid...
Lynch syndrome is an autosomal dominant disorder caused by germline mutations in mismatch repair (MMR) genes. The main feature of this disorder is an early onset of hereditary colorectal cancer in addition to other cancers arising from different tissues. Here, we report an Iranian family with several members affected with Lynch syndrome related cancers. Exome sequencing with focus on 14 genes related...
Mammalian exchange protein directly activated by cAMP isoform 1 (EPAC1), encoded by the RAPGEF3 gene, is one of the two-membered family of cAMP sensors that mediate the intracellular functions of cAMP by acting as guanine nucleotide exchange factors for the Ras-like Rap small GTPases. Extensive studies have revealed that EPAC1-mediated cAMP signaling is highly coordinated spatiotemporally through...
Fragile X syndrome, which is caused by mutation in the FMR1 gene region, is one of the most prevalent forms of mental retardation. Direct diagnosis of the disease is based on PCR and southern blot analysis, but because of technical problems, use of polymorphic DNA markers can be helpful for carrier detection and prenatal diagnosis in families with an affected individual. The polymorphic markers usually...
Cervical cancer is the second most frequent cancer in women worldwide and is associated with genetic alterations, infection with human papilloma virus (HPV), angiogenesis and inflammatory processes. The idea that inflammation is involved in tumorigenesis is supported by the frequent appearance of cancer in areas of chronic inflammation. On the other hand, the inflammatory response is controlled by...
Fructans are accessible carbohydrate reserves in various plant species, which possess many physiological functions including anti-oxidation, stabilizing subcellular structures, and osmotic adjustment. In addition, fructans may play important roles in stress tolerance in plant species. In this study, we isolated a Psathyrostachys huashanica (2n=2x=14, NsNs) sucrose:fructan-6-fructosyltransferase (Ph-6-SFT)...
Systemic lupus erythematosus (lupus) is a genetically heterogeneous autoimmune disorder with an obscure etiology. With 92–94% of human genes exhibiting alternative splicing, gaining insights to such events may lead to better diagnostics. Herein, we explored the genome-wide peripheral blood transcriptome of lupus and its severe form lupus-nephritis (LN) compared to healthy controls (HC). Age/gender/ethnically-matched...
Caspase 10 is an initiator caspase in death cascades of death receptor mediated apoptotic signaling. We identified and molecularly characterized a novel homolog of caspase 10 from black rockfish (Sebastes schlegelii) and designated as RfCasp10. The complete coding region of RfCasp10 was found to consist of 1659bps, encoding a 553 amino acid protein with a predicted molecular mass of 61.7kDa. The characteristic...
Blunt snout bream (Megalobrama amblycephala), a prevalent species in China's intensive polyculture systems, is highly susceptible to hepatic steatosis, resulting in considerable losses to the fish farming industry. Due to a lack of genomic resources, the molecular mechanisms of lipid metabolism in M. amblycephala are poorly understood. Here, a hepatic cDNA library was generated from equal amounts...
Disease-associated mutations in GJB2 gene are one of the major reasons that can cause non-syndromic sensorineural hearing loss (NSHL). GJB2 gene deafness has various clinical phenotypes. This study aims to analyze characteristics and relationships of clinical phenotypes through analyzing 1481 NSHL cases and 190 GJB2 deafness patients (with dual gene mutations).All the patients diagnosed as deaf disease...
The chocolate mahseer (Neolissochilus hexagonolepis) is an important food and game fish of North Eastern India. To study the phylogenetic status we sequenced the complete mitochondrial genome of N. hexagonolepis. The mitogenome is 16,563bp in length and composed of 13 protein coding genes, 22 tRNAs, 2 rRNAs and one putative control region. The overall base composition was A 31.8%, T 25.0%, G 15.8%,...
Stroke is a multi-factorial disorder and has become the leading cause of death and disability worldwide. Recent genome-wide association studies (GWAS) have identified a significant association of single-nucleotide polymorphism (SNP) rs2107595 in HDAC9 gene with large-vessel ischaemic stroke (IS) in the European populations. The aim of this study is to examine the association of HDAC9 gene rs2107595...
Ischemic postconditioning (IPost) is a strategy to provide protection against ischemia–reperfusion (IR) injury. The cardioprotective effects of IPost in cases of ischemic heart disease along with co-morbidities like hyperthyroidism remain unknown. The aim of this study was to investigate the effects of IPost on expression of eNOS, iNOS, Bax, and Bcl-2 genes in hyperthyroid male rats, subjected to...
Irisin, a novel myokine encoded by fibronectin type III domain-containing protein 5 gene (FNDC5), is reported to stimulate brown fat-like development of white fat tissue and thermogenesis in mammals recently. However, information about the structure, tissue expression, and roles of FNDC5/irisin remains unknown in non-mammalian vertebrates including birds. In this study, we first cloned the FNDC5 (cFNDC5)...
