Characterization of differentially expressed genes in the bovine T lymphoma cell line.
A differential display (D.D.) analysis was made to detect differentially expressed genes in a bovine T lymphoma cell line, BTL-26, derived from the calf type of sporadic bovine lymphosarcoma. A D.D. analysis comparing BTL-26 with the bovine epithelial cell line CKT-1 and healthy bovine thymocytes yielded 24 cDNA clones. The DNA sequencing analysis followed by a homology search showed that 20 of the 24 cDNA clones had no significant homology to any sequences in DNA data base. The remaining four genes were homologous to known sequences. Northern blot hybridization among BTL-26, CKT-1 and healthy bovine thymocytes showed that a cDNA clone, BC8, was differentially expressed in BTL-26. The cloning of full-length cDNA for the BC8 clone and its DNA sequences showed that the BC8 clone is a bovine nuclear domain protein homologous to the human NDP52 gene. Northern blot analysis showed that the BC8 clone bovine NDP52 was predominantly expressed in tumor cell line BTL-26, compared with the transcripts from several bovine tissues.[1]References
