Heme oxygenase (HO) that catalyzes the degradation of heme, is involved in responding and using oxygen in teleost fish. Physiologic heme degradation can be catalyzed by two isozymes of HO (HO-1 and HO-2). In fish, the molecular constructions, expression characteristics and hypoxic regulation of HO-2 are still not well known. Here, we report the isolation and characterization of duplicated HO-2 genes in blunt snout bream, a hypoxia sensitive fish species. Blunt snout bream HO-2a and -2b genes shared a relatively low sequence identity of 67%...

The development of vertebrate appendages, especially the limb and feather buds are orchestrated by numerous secreted signalling molecules including Sonic Hedgehog, Bone Morphogenetic Proteins, Fibroblast Growth Factors and Wnts. These proteins coordinate the growth and patterning of ectodermal and mesenchymal cells. The influence of signalling molecules is affected over large distances by their concentration (morphogen activity) but also at local levels by the presence of proteins that either attenuate or promote their activity...

Various mutations in PARK2 gene, which encodes the protein parkin, are significantly associated with the onset of autosomal recessive juvenile Parkinson (ARJP) in neuronal cells. Parkin is a multi domain protein, the N-terminal part contains the Ubl and the C-terminal part consists of four zinc coordinating domains, viz., RING0, RING1, in between ring (IBR) and RING2. Disease mutations are spread over all the domains of Parkin, although mutations in some regions may affect the functionality of Parkin more adversely...

Osteoporosis, the most common bone metabolic disease affecting nearly 200 million people worldwide is under the strong influence of genetic components. Simultaneously, adipogenesis and osteogenesis are two highly coordinated processes imperative for the maintenance of bone quality and quantity, where any perturbation leads to pathological conditions of obesity, osteopenia and osteoporosis. To delineate this osteogenic-adipogenic connection, a total of 254 cases (T-score<-1.0 SD) and 250 age, gender and ethnicity matched healthy controls (T-score≥-1...

Renal ischemia reperfusion injury (IRI) is frequently encountered after kidney transplantation and is a leading cause of acute renal failure. Aberrant gene expression and epigenetic regulation occur during the pathophysiology of IRI. In this study, we used reduced representation bisulfite sequencing to identify the DNA methylome of renal tissues during IRI and the sham-operated tissues in C57BL/6. The methylation status of approximately 1.29 million CpGs located in an average of 11554 CpG islands and 17113 promoters in genome was determined...

Serpins are a family of serine protease inhibitors that are found widely in insects. They play an important role in insect physiological responses, such as innate immunity and development. In this study, we obtained the Bombyx mori serpin6 (BmSerpin6) sequence from National Center for Biotechnology Information (NCBI) and the silkworm genome database (SilkDB). Reverse transcription PCR (RT-PCR) results showed that BmSerpin6 was expressed highly in hemocytes, the midgut, and the fat body. After challenging with Micrococcus luteus (Mi) and Serratia marcescens (Sm), the BmSerpin6 expression level was induced significantly...

Semaphorin 3A (Sema3a) as an immune modulator could participate in the pathogenesis of autoimmune diseases. In the current study, we aimed to investigate Sema3A expression in peripheral blood mononuclear cells (PBMCs) and its serum level in relapsing-remitting multiple sclerosis (RRMS) patients. Fifteen newly determined and untreated RRMS patients were chosen and assessed in relapsing and remitting phases in compare with fifteen healthy individuals. In consistent with previous findings in other autoimmune diseases, our results revealed that serum level of Sema3A and its expression in PBMCs of RRMS patients were significantly lower than in normal subjects...

The adaptive evolution of animals to high-elevation environments has been extensively studied in vertebrates, while few studies have focused on insects. Gynaephora species (Lepidoptera: Lymantriinae) are endemic to the Qinghai-Tibetan Plateau (QTP) and represent an important insect pest of alpine meadows. Here, we present a detailed comparative analysis of the mitochondrial genomes (mitogenomes) of two Gynaephora species inhabiting different high-elevation environments: G. alpherakii and G. menyuanensis. The results indicated that the general mitogenomic features (genome size, nucleotide composition, codon usage and secondary structures of tRNAs) were well conserved between the two species...

Interferon regulatory factor 5 (IRF5) regulates type I interferon (IFN)-responsive genes, and has been one of the most consistently associated genes with systemic lupus erythematosus (SLE). We sought to investigate whether IRF5 haplotypes are associated with risk for SLE in the genetically homogeneous Greek population of the island of Crete, as well as whether these haplotypes are associated with increased type I IFN. 322 SLE patients and 247 healthy controls from Crete were genotyped for rs2004640, rs3807306, rs10488631 and rs2280714 SNPs of IRF5 gene by using Taqman primer-probe sets...

Compelling evidences anticipated the well acclamation of involvement of exogenous and endogenous polyamines (PAs) in conferring salt tolerance in plants. Intracellular PA's anabolism and catabolism should have contributed to maintain endogenous PAs homeostasis to induce stress signal networks. In this report, the evolutionary study has been conducted to reveal the phylogenetic relationship of genes encoding enzymes of the anabolic and catabolic pathway of PAs among the five plant lineages including green algae, moss, lycophyte, dicot and monocot along with their respective exon-intron structural patterns...

The fat mass and obesity associated (Fto) and iroquois homeobox 3 (Irx3) genes have been recognised as important obesity-related genes. Studies on the expression of these genes in the fat tissue of human and mouse have produced inconsistent results, while similar data on rat are limited. Environmental factors such as diet, should be considered as potential modulators of gene transcript levels through epigenetic mechanisms including DNA methylation. The aim of this study was to evaluate transcription levels and DNA methylation profiles of rat Fto and Irx3 genes in two white adipose tissue depots in response to high-fat and high-protein diets...

Breast carcinoma is the most common malignancy in women, and the incidence rate has increased dramatically in recent years. Metastasis is responsible for most advanced breast cancer mortality, but the underlying mechanisms remain poorly understood despite extensive research. Recently, short non-coding RNA molecules, including miRNAs, which mediate changes in signalling pathways, have emerged as metastatic regulators of the breast carcinoma. Previous reports have suggested that miR-130b-3p has both oncogenic and tumour suppressor functions in a cancer type-dependent manner...

Vertebrate development is orchestrated by secreted signalling molecules that regulate cell behaviour and cell fate decisions during early embryogenesis. The activity of key signalling molecules including members of Hedgehog, Bone Morphogenetic Proteins and Wnt families are regulated by Glypicans, a family of GPI linked polypeptides. Glypicans either promote or inhibit the action of signalling molecules and add a layer of complexity that needs to be understood in order to fully decipher the processes that regulate early vertebrate development...

The splicing factors RDM16 and STA1 have been reported to play a role in the RNA directed DNA Methylation (RdDM) pathway. In this pathway, small interfering RNAs guide de-novo methylation of homologous DNA sequences. DNA methylation is epigenetic marks, which can suppress transposable elements, repeat sequences and genes. It also affects the chromatin structure. Upon deletion of RDM16 and STA1, previous studies based on gene level analysis were unable to find differentially spliced events implicated in RdDM pathway...
