[The genes associated with geldanamycin inhibiting replication of herpes simplex virus type 1].
Geldanamycin (GA), an ansamycin antibiotic specifically binding heat shock protein 90 (Hsp90), exhibits a broad-spectrum antiviral effect. Herpes simplex virus type 1(HSV-1) replication in vitro was significantly inhibited by GA treatment. To explore the antiviral mechanism of GA against HSV-1, the 7267-spot human long oligonucleotide microarrays were applied to investigate the genes which might involved in the antiviral activity of GA in HeLa cells infected by HSV-1. Meanwhile, the reverse regulation of GA and HSV-1 on ACTG1, RAN, SOD1, HYAL1 were validated by using semi-quantitative RT-PCR. It is the first report of gene expression profile in cells infected by virus with GA treatment. The general impact of GA on cellular transcription may help to gain an insight into mechanism of its antiviral effect.
