Abstract
The promoters of the adenovlrus 2 major late gene, the mouse β-globin gene, the mouse lmmunoglobulin VH gene and the LTR of the human T-lympho-tropic retrovirus type I were tested for their transcription activities in cell-free extracts of four cell lines; HeLa, CESS (Epstein-Barr virus-transformed human B cell line), MT-1 (HTLV-I-infected human T cell line without viral protein synthesis), and MT-2 (HTLV-I-infected hitman T cell line producing viral proteins). LTR was preferentially transcribed in the extracts of MT-2 although the other three genes were transcribed with relatively constant efficiencies in different extracts. The results agree well with the previous in vivo studies on the promoter activity of HTLV-I LTR. Mixing of HeLa and MT-2 extracts revealed the presence of a LTR-specific stimulating activity in MT-2 extracts.
