Ferric uptake regulator (Fur) is a transcriptional regulator controlling the expression of genes involved in iron homeostasis and plays an important role in pathogenesis. Fur-regulated sRNAs/CDSs were found to have upstream Fur Binding Sites (FBS). We have constructed a Positional Weight Matrix from 100 known FBS (19 nt) and tracked the ‘Orphan’ FBSs. Possible Fur regulated sRNAs and CDSs were identified...
RIG-I (retinoic acid-inducible gene I) is an essential cytosolic pathogen recognition receptor that binds to a variety of viral RNA or DNA to induce type I interferons. In the present study, insert–deletion polymorphisms in promoter and introns of CiRIG-I (Ctenopharyngodon idella RIG-I) were explored, their associations with resistance/susceptibility to grass carp reovirus (GCRV) were analyzed. To...
Nucleotide-binding oligomerization domain containing 2 (NOD2) plays a pivotal role in the host innate and adaptive immunity by recognizing the pathogenic agents. Therefore, its genetic polymorphisms and association with susceptibility to infectious diseases have been widely reported in human and farm animals. In the present study, we investigated the genetic polymorphisms in 3171bp coding region of...
Tropinone reductases (TRs) are small proteins belonging to the SDR (short chain dehydrogenase/reductase) family of enzymes. TR-I and TR-II catalyze the conversion of tropinone into tropane alcohols (tropine and pseudotropine, respectively). The steps are intermediary enroute to biosynthesis of tropane esters of medicinal importance, hyoscyamine/scopolamine, and calystegins, respectively. Biosynthesis...
There has been significant interest in the expression and function of dermatopontin (DPT) in mammals owing to recent evidence pointing to its critical role in collagen fibrillogenesis. Despite this interest, limited information is available about the site/s of DPT mRNA expression or changes in expression in vivo. We used reverse-transcription polymerase chain reaction and in situ hybridization to...
Congenital heart defects (CHD) are one of the most common defects in offspring of diabetic mothers. There is a clear association between maternal diabetes and CHD; however the underlying molecular mechanism remains unknown. We hypothesized that maternal diabetes affects with the expression of early developmental genes that regulate the essential developmental processes of the heart, thereby resulting...
Microduplication at 17p13.3 and microdeletion at 21q22 are both rare chromosomal aberrations. The presence of both genomic imbalances in one patient has not been previously reported in literature. In this study, we performed a molecular diagnostic testing with a whole genome microarray on a 3-year-old boy with developmental delay, mental retardation and multiple malformations.A routine G-banding karyotype...
The aim of the study was to identify the causative gene defects associated with familial adenomatous polyposis (FAP) in two Chinese pedigrees.The diagnosis of FAP patients was confirmed by clinical manifestations, family histories, colonoscopy and pathology examinations. Blood samples were collected and genomic DNA was extracted. The mutation analysis of the adenomatous polyposis coli (APC) and human...
The INU1 gene (Accession number: JX073660) encoding exo-inulinase from Cryptococcus aureus HYA was cloned and characterized. The gene had an open reading frame (ORF) of 1653bp long encoding an inulinase. The coding region of the gene was not interrupted by any intron. It encoded 551 amino acid residues of a protein with a putative signal peptide of 23 amino acids and the calculated molecular mass...
Aelurostrongylus abstrusus (Railliet, 1898) is a metastrongylid nematode of major clinical relevance in felids, causing aelurostrongylosis. In spite of its clinical importance in cats, the genetics, epidemiology and biology of this parasite are not entirely understood. mt DNA can provide markers for studies of these areas, but genetic data are scant for A. abstrusus and related lungworms. Here, the...
Individuals who are carriers of deletions of various sizes that cause haploinsufficiency in the contiguous WT1 and PAX6 genes, located on chromosome 11p13 approximately 4Mb centromeric to the BDNF gene, are susceptible to Wilms tumor, aniridia, mental retardation, genitourinary anomalies and obesity (WAGRO syndrome). The molecular characterization of the wide deletion 11p15.1p12 arr (18676926–36576388)...
Cytotoxic T lymphocyte-associated protein 4 (CTLA-4) is an important mediators of T-cell activation in autoimmune diseases. The association of polymorphisms of CTLA gene with type 1 diabetes (T1D) has widely been reported; however, the results are inconsistent. To obtain further insight into this topic, we performed a meta-analysis of 52 studies involving a total of 11,017 cases and 14,191 controls...
Mutations of CYP17A1 gene could cause complete or partial, combined or isolated 17α-hydroxylase/17,20-lyase enzyme deficiencies (17OHD). We intended to investigate the CYP17A1 mutation in five unrelated patients and analyze its possible influence on phenotype of an atypical 17OHD patient presented with micropenis, hypertension and intermittent hypokalemia. Steroid hormones were assayed in these patients...
To investigate the role of liver-specific expression of glucokinase (GCK) in the pathogenesis of hyperglycemia and to identify candidate genes involved in mechanisms of the onset and progression of maturity onset diabetes of the young, type 2 (MODY-2), we examined changes in biochemical parameters and gene expression in GCK knockout (gck w/– ) and wild-type (gck w/w ) mice as they...
Prolidase deficiency (PD) is a rare inborn disorder of collagen metabolism characterized by chronic recurrent cutaneous ulceration. We report a novel 3bp insertion in the 12th exon of the PEPD gene in two Kashmiri siblings with prolidase deficiency phenotype. This mutation results in addition of an extra alanine residue at the amino-acid position number 304 of prolidase peptide. The structural analysis...
The effects of exercise on adiponectin levels have been reported to be variable and may be attributable to an interaction between environmental and genetic factors. The single nucleotide polymorphisms (SNP) 45 (T>G) and SNP276 (G>T) of the adiponectin gene are associated with metabolic risk factors including adiponectin levels. We examined whether SNP45 and SNP276 would differentially influence...
Obesity is one of the most complex human diseases that are widely concerned and studied. More recently, copy number variations (CNVs) emerge as another important genetic marker to influence various human diseases. To elucidate the relationship between obesity and CNVs, this current study selected obesity-related candidate CNVs and analyzed their association with body mass index (BMI). Results showed...
Fertilised eggs of Senegalese sole were incubated at 15, 18 or 21°C, and after hatching all larvae were reared at 21°C until 30days post-hatch. By this point larvae from the 18 or 21°C temperature groups had 11 and 9% more muscle fibres than those from 15°C, respectively. Hyperplastic growth during metamorphosis was higher in larvae from 18°C. Embryonic temperature induced gene expression changes,...
Protamine is a small, arginine-rich, nuclear protein that replaces histone late in the haploid phase of spermatogenesis and is believed to be essential for sperm head condensation and DNA stabilization. Protamine has many biological activities and has roles in hematopoiesis, immune responses, the nervous system and bone metabolism. Bone sialoprotein (BSP) is a mineralized connective tissue-specific...
