[Hepatitis C virus NS5A protein upregulates survivin gene expression]
1Center for Liver Diseases, Second Xiangya Hospital, Central South University, Changsha 410011, China.
Objective:
To investigate whether the nonstructural protein 5A (NS5A) encoded by the human hepatitis C virus RNA genome could affect the expression of the survivin gene.
Methods:
HCV NS5A expression plasmid (pCNS5A) was transfected into HepG2 cells using a lipofectin reagent and the HCV NS5A protein was detected using immuno-histochemistry staining. Survivin mRNA was evaluated by reverse transcriptase polymerase chain reaction (RT-PCR) and the expression of survivin protein was detected using Western blot.
Results:
HCV NS5A protein was detected in the cytoplasm of the HepG2 cells transfected with pCNS5A, and the expressions of survivin mRNA and survivin protein were both up-regulated in the presence of the HCV NS5A protein.
Conclusions:
HCV NS5A protein can stimulate survivin protein expression, and this might be the result of the strengthening of the survivin gene transcription.
