Expression of PHGPx in mammalian cells and its antiviral effect against coxsackievirus group B

To express human phospholipid hydroperoxide glutathione peroxidase (PHGPx) in eukaryotic cells and to study its antiviral effect against Coxsackievirus B3m (CVB3m) in vitro, PHGPx cDNA was amplified from a human testis library using specific primers and cloned into expression vector pcDNA3. I/His. Expression of PHGPx was performed in COS-1 cells. The antiviral effect was studied by the treatment of HeLa cells with the recombinant PHGPx. Results showed that the activity of PHGPx expressed in COS-1 cells was 5-fold higher than that in control group, and it inhibited the cytopathic effect on HeLa cells caused by CVB3m. It can be concluded that recombinant PHGPx expressed in COS-1 cells has antiviral effect against CVB3m in vitro.
