ABSTRACT

This invention provides a method of indentifying a tumor suppressor gene of a cell(s) which comprises the following steps: a) obtaining cDNA or mRNA from a normal cell(s); b) preparing cDNA from the cell(s) if mRNA is obtained in step (a); c) preparing a library from said cDNA, wherein the cDNA is under control of an inducible expression control system which also carries a selectable gene; d) introducing the vector library into a population of cell(s) expressing a transformed phenotype; e) placing the introduced transformed cell(s) from step (d) in conditions permitting expression of the cDNA and an effective concentration of an appropriate selection agent to select the cell(s) expressing the selectable gene; f) identifying the cell(s) which express the normal phenotype; and g) analyzing the cell(s) so identified so as to characterize the DNA and thus identify the tumor suppressor gene. Analogous methods to identify tumor suppressors in normal cells and to identify genes associated with unknown genetic defects are also described. More... »
