Abstract

Two of the five nondefective adenovirus 2 (Ad2)-simian virus 40 (SV40) hybrids induce SV40 transplantation resistance in immunized hamsters. These two hybrids, Ad2(+)ND(2) and Ad2(+)ND(4), contain 32 and 43% of the SV40 genome, respectively. The pattern of induction of SV40 transplantation antigen (TSTA) by the various hybrids differentiates TSTA from both SV40 U and T antigens. Since the SV40 RNA induced by both these hybrids is early SV40 RNA, these findings confirm that TSTA is an early SV40 function. By combining available data on SV40 antigen induction by these hybrids with electron microscopy heteroduplex mapping studies, the DNA segment responsible for the induction of SV40 TSTA can be inferred to lie in the region between 0.17 and 0.43 SV40 units from the site on the SV40 chromosome cleaved by E. coli R(1) restriction endonuclease.

摘要

五种无缺陷的腺病毒2(Ad2)-猴病毒40(SV40)杂种中的两种可在免疫的仓鼠中诱导SV40移植抗性。这两种杂种,Ad2(+)ND(2)和Ad2(+)ND(4),分别包含SV40基因组的32%和43%。各种杂种诱导SV40移植抗原(TSTA)的模式将TSTA与SV40 U抗原和T抗原区分开来。由于这两种杂种诱导的SV40 RNA都是早期SV40 RNA,这些发现证实TSTA是SV40的早期功能。通过将这些杂种诱导SV40抗原的现有数据与电子显微镜异源双链图谱研究相结合,可以推断负责诱导SV40 TSTA的DNA片段位于SV40染色体上被大肠杆菌R(1)限制性内切酶切割的位点起0.17至0.43 SV40单位之间的区域。
