AIM
To study genes trans-regulated by nonstructural protein 5A of hepatitis C virus by microarray assay.
METHODS
The recombined expression plasmid pcDNA3.1(-)-NS5A was constructed, and HepG2 cells were transfected. Total mRNA was isolated from the HepG2 cells transfected with pcDNA3.1(-) and pcDNA3-NS5A, respectively. Microarray was employed for detecting and analyzing of both mRNA from the HepG2 cells.
RESULTS
After transfecting HepG2 cells, we found 28 genes have been up-regulated, and 26 genes down-regulated. Their encoding proteins were involved in cell signal transduction, cell proliferation and differentiation.
CONCLUSION
Microarray technology is successfully used to screen the genes trans-regulated by nonstructural protein 5A of hepatitis C virus, which brings some new clues for studying the trans-regulated and immune regulation mechanism of NS5A.
