A B-cell line having translocations of chromosome 14 at break band q11 (the assigned locus of the alpha-chain gene of the T-cell antigen receptor) and chromosome 3 at break band p25 (the assigned locus of the c-raf-1 oncogene) was established from peripheral blood leukocytes of an adult T-cell leukemia (ATL) patient.
We assayed the capacity of tumor promoters to induce human T-cell leukemia/lymphoma virus (HTLV) structural proteins p19 and p24 from the HTLV genome-carrying adult T-cell leukemia (ATL) cell lines, MT-1 and KH-2Lo, and fresh ATL cells.
