The human BSF-2/IL-6 gene consists of five exons and four introns and its organization shows a distinctive similarity to granulocyte colony-stimulating factor gene. The two genes have the same number of exons and introns and the size of each exon is strikingly similar. The BSF-2/IL-6 mRNA was found to be constitutively expressed in a human T cell leukemia virus-1 transformed T cell line, TCL-Na1, a bladder cell carcinoma line, T24, and an amnion derived cell line, FL. The BSF-2/IL-6 mRNA was also found to be inducible with interleukin-1 beta in an astrocytoma line, U373 and a glioblastoma line, SK-MG-4. S1 mapping and primer extension analyses showed the presence of multiple initiation sites and the preferential utilization of a different initiation site for each individual tissue tested.
