With the wide application of RNA-Seq technology, thousands of circular RNAs (circRNAs) have been identified in different type of tissues and cells in many organisms, but little is known on the human aortic valve expressed circRNAs. In this study, we identified all circRNAs in two calcified human aortic valves, and characterized the features of all circRNAs. A total of 5476 circRNAs were identified...
Atopic dermatitis (AD) is a chronic inflammatory skin disease. The 5q22.1 region was found to have an association with AD in our previous genome-wide association study (GWAS).To identify the AD susceptibility gene in 5q22.1 and observe its expression in AD tissues.Suggestive indels from the GWAS data were genotyped in 3013 AD patients and 5075 controls from the Chinese Han population with the SequenomMassArray...
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...
The structure of goldfish (Carassius auratus) Tgf2 transposase is still poorly understood, although it can mediate efficient gene transfer in teleost fish. We hypothesized the existence of a nuclear localization signal (NLS) within Tgf2 transposase to assist transport into the nucleus. To explore this, 15 consecutive amino acid residues (656–670 aa) within the C-terminus of Tgf2 transposase were predicted...
Fgfr1 is a fibroblast growth factor receptor involved in regulating cell growth, proliferation, differentiation and migration. Here, we report the isolation and characterization of duplicated fgfr1 genes in blunt snout bream (Megalobrama amblycephala). Blunt snout bream fgfr1a and -1b cDNAs were found to share a relatively high sequence identity of 82%. During embryogenesis, both fgfr1a and -1b mRNAs...
Interleukin 18 (IL-18) is a proinflammatory cytokine with an ability to accelerate cell proliferation through activating other factors. However, little is yet understood of the role of IL-18 in the regulation of liver regeneration (LR). To study the effect of IL-18 on LR, the gene expression profiles of hepatocytes isolated from rat regenerative liver were determined by Rat Genome 230 2.0 microarray...
The goldfish (Carassius auratus) Tgf2 transposon is a vertebrate DNA transposon that belongs to the hAT transposon family. In this study, we constructed plasmids containing either the full-length Tgf2 transposon (pTgf2 plasmid) or a partially-deleted Tgf2 transposon (ΔpTgf2 plasmid), and microinjected these plasmids into fertilized zebrafish (Danio rerio) eggs at the one- to two-cell stage. DNA extracted...
Insulin-like growth factor 2 (IGF2) is a potent mitogenic and survival factor involved in the regulation of growth, development and reproduction in animals. Only one IGF2 gene exists in mammals. Recently, two igf2 genes have been identified in zebrafish, which presumably resulted from gene duplication. However, sequence information of duplicated igf2s and their functional regulation in other teleost...
Hox genes encode transcription factors that play a key role in specifying the body plan in metazoans and are therefore essential in explaining patterns of evolutionary diversity. While each Hox cluster contains the same genes among the different mammalian species, this does not happen in ray-finned fish, in which both the number and organization of Hox genes and even Hox clusters are variables. Here...
