Abstract
AIM: To study the molecular mechanism of NS5A-TP4 in the up- and down-regulated genes of hepatocyte by cDNA microarray assay.
METHODS: HepG2 cells were transfected by recombined expression plasmid pcDNA3.1(-)-NS5A-TP4. Total RNA was isolated from the transfected HepG2 cells with pcDNA3.1(-) and pcDNA3.1(-)-NS5A-TP4, respectively. cDNA was prepared by reverse transcription. cDNA microarray was conducted for screening of up- and down-regulated genes of both HepG2 cells.
RESULTS: After screening with cDNA microarray, we found that 12 genes were up-regulated, and 6 genes down-regulated. Some of them were involved in cell signal transduction, cell proliferation, and carcinogenesis.
CONCLUSION: cDNA microarray is an important choice for the analysis of target genes of NS5ATP4 transactivation. The obtained sequences bring some new clues for studying the biological functions of NS5ATP4 and infection mechanism of HCV.
