BACKGROUND Hypoxia-inducible factors (HIFs) are involved in adaptive and survival responses to hypoxic stress in mammals. In fish, very little is known about the functions of HIFs. RESULTS We have cloned and characterized two distinct HIF-alpha cDNAs--gcHIF-1alpha and gcHIF-4alpha--from the hypoxia-tolerant grass carp. The deduced gcHIF-1alpha protein is(More)
Glucose transporters (GLUTs) have been implicated in adaptive and survival responses to hypoxic stress in mammals. In fish, the expression and regulation of GLUT in relation to hypoxia remains unexplored. Here we describe the identification of a hypoxia-responsive glucose transporter gene (gcGLUT) and the corresponding full-length cDNA from the grass carp.(More)
BACKGROUND Aeromonas spp. have been regarded as "emerging pathogens". Aeromonads possess multifactorial virulence and the production of many of these virulence determinants is associated with high cell density, a phenomenon that might be regulated by quorum sensing. However, only two species of the genus are reported to possess the luxRI quorum sensing gene(More)
BACKGROUND Current understanding on the relationships between hypoxia, hypoxia-inducible factor-1 (HIF-1) and telomerase reverse transcriptase (TERT) gene expression are largely based on in vitro studies in human cancer cells. Although several reports demonstrated HIF-1- mediated upregulation of the human TERT gene under hypoxia, conflicting findings have(More)
We have isolated a 1586-bp full-length CITED3 cDNA from grass carp which specifies for a cAMP-responsive element-binding protein/p300-interacting transactivator with glutamic acid (E)/aspartic acid (D)-rich C-terminal domain protein. The cDNA, designated as gcCITED3, has an open reading frame of 762 bp and encodes a protein of 253 amino acids with a(More)
BACKGROUND CITED proteins belong to a family of non-DNA-binding transcriptional co-regulators that are characterized by a conserved ED-rich domain at the C-terminus. This family of genes is involved in the regulation of a variety of transcriptional responses through interactions with the CBP/p300 integrators and various transcription factors. In fish, very(More)
