Three kinds of human choriocarcinoma cell lines (BeWo, HCCM-5, and NUC-1) were used for examining the antiviral and antiproliferative activities of human interferons (IFNs) in vitro and in vivo. All of the cell lines showed only low sensitivity to the antiviral action of every IFN-alpha, IFN-beta, and IFN-gamma against vesicular stomatitis virus infection. However, 2-5A synthetase was normally induced by IFN-alpha in all of the cell lines. The [3H]thymidine incorporation of both BeWo and HCCM-5 cells was suppressed in dose-dependent manner at 48 hr after treatment with 1 to 1,000 units (U)/ml of IFN-alpha or IFN-beta and the growth of them was also slightly inhibited when treated continuously with 1,000 U/ml for 6 days in vitro. Another cell line NUC-1 was the least sensitive to these IFNs among the three cell lines. IFN-gamma did not show any antiproliferative effect on these cell lines. The intraperitoneal administration of 5000 or 10,000 U of IFN-beta suppressed the growth of xenografts developed in hamster cheek pouches and subcutis of nude mice when its administration was initiated on the first day of cell inoculation. These results indicate that although some heterogeneities exist among the cell lines choriocarcinoma cells are weakly sensitive to the antiproliferative activity of human IFNs.
