Molecular cloning and expression of IRF1 in large yellow croaker, Pseudosciaena crocea
چکیده انگلیسی

The interferon regulatory factor (IRF) family is known to be crucial in mediating the host defense against pathogen infection by binding to characteristic elements in promoters within interferon (IFN) genes and IFN-inducible genes. In this report, the full-length cDNA of IRF1 was cloned from the large yellow croaker, Pseudosciaena crocea. It was of 1667 bp, including a 5′-terminal untranslated region (UTR) of 142 bp, a 3′-terminal UTR of 674 bp and an open reading frame (ORF) of 861 bp encoding a polypeptide of 286 amino acids. The putative amino acid sequence contained a typical IRF domain at the N-terminal. Quantitative real-time reverse transcription PCR analysis revealed a broad expression of IRF1 in most detected tissues, with the predominant expression in the gill and spleen and the weakest expression in the brain. The expression of IRF1 after challenged with LPS and poly I:C was tested in blood, spleen and liver, which showed that IRF1 changed obviously with the most significantly up-regulated expression was 37 times (at 6 h) after injection with poly I:C in the blood and 13 times (at 3 h) after injection with LPS in the liver compared with the control values (p < 0.01). These results indicated that as a crucial factor in regulating the IFN and IFN-inducible elements in mammals, IRF1 might play an important role in large yellow croaker defense against the pathogen infection.
