The present invention provides methods and constructs for selectively
expressing an Apoptosis-Inducing Gene (AIG) in a population of cells that
overexpress cyclooxygenase-2 (COX-2) to induce apoptosis in the cell. To
achieve this goal a chimeric gene construct is used that comprises a
cyclooxygenase-2 promoter (COX-2 promoter) that is operably linked to at
least one AIG such that the COX-2 promoter is activated in cells that
overexpress COX-2, thereby resulting in transcription and translation of
the AIG, which in turn activates apoptosis in the cell. Thus, apoptosis
is selectively induced in only those cells capable of overexpressing
COX-2.
