ABSTRACT:
A method for producing a complementary DNA (cDNA) library enriched in ligand-inducible genes of a cell is described. The method includes activating a cellular ligand receptor for a predetermined period of time in the presence of labelled RNA precursors and a substance which enhances the level of RNA in the cell. The RNA precursors are incorporated into the RNA synthesized by the cell in response to receptor activation. The labelled RNA is separated from unlabelled RNA and used to prepare cDNA. The cDNA is cloned into host cells to provide a cDNA library of cDNA-containing clones, which is then screened for clones containing ligand-induced genes. Also described are several novel ligand-induced genes identified using the method of the invention.
