The biological!activities i.e. antineoplastic activities and antiviral activity of the two novel kinds of interferons hIFN-?1 and hIFN-? were studied and compared. First the fusion expression vector pcDNA3.1A-hIFN-?1-His and pcDNA3.1A-hIFN-?-His by PCR was constructed,then the two kinds of plasmids were transfected into WI-38 (human embryonic lung cells) with liposome. And cytopathic effect (CPE) suppression test was used to study and compare the antiviral activities of rhIFN-?1-His and rhIFN-?-His, meanwhile MTT assay was used to detect their antineoplastic activities.It was found that, antiproliferative activity and MxA protein induction shown by rhIFN-?1-His is more powerful than of rhIFN-?-His. The antiviral molecular mechanisms of both hIFN-?1 and hIFN-? are related to MxA.The foundation for further study on the bioactivities and mechanism of action of hIFN-?1 and hIFN-? was established.
