Title: Rous sarcoma virus does not induce sarcoma in early chick embryos by lack of the v-src gene expression.

No sarcoma but blister formation was observed in those RSV-inoculated embryos. Protein kinase activity of pp60v-src in RSV-inoculated embryos, even in the site of virus inoculation, was the same as that in mock-infected embryos. This indicated that the expression of the v-src gene did not attain superiority over that of the c-src gene in RSV-inoculated embryos. The v-src gene was detected in every DNA from tissues of RSV-inoculated embryos but not in DNAs from tissues of RSV-inoculated chicken except for the DNA from Rous sarcoma. Those results confirmed that the lack of sarcoma induction in early avian embryos by RSV was due to the lack of the expression of the v-src gene which was present in the target cells.Read More
