title: TNF susceptibility-related gene expression.
abstract: A series of BWL hybridoma lines has been generated by cell fusion of a TNF-resistant BW5147 cell line and a highly TNF-sensitive WR19L cell line, and has exhibited a wide variety of TNF susceptibility. A cDNA library, BWL47rp10, from a TNF-susceptible hybridoma line BWL47 has been screened by hybridization with a 32P-labeled subtraction cDNA probe from WR19L cells. Thirty-nine candidates for TNF susceptibility were cloned, and 20 clones larger than 1.0 kb have been examined so far. A cDNA clone, 10-2, hybridized to mRNA of 1.8 kb. It was expressed higher in highly TNF-sensitive cells, especially in BWL47, BWL40, and BWL57 cells. Thus, at least, the expression of the mRNA identified with cDNA 10-2 correlated well with TNF susceptibility in BWL cells, although its functional identity remains to be determined.
