Abstract

The present invention provides methods and compositions for conferring selective death on cells expressing a specific target precursor messenger RNA (selective target pre-mRNA). The compositions of the invention include pre-trans-splicing molecules (PTMs) designed to interact with a target precursor messenger RNA molecule (target pre-mRNA) expressed within a cell and mediate a trans-splicing reaction resulting in the generation of a novel chimeric mRNA molecule (chimeric mRNA) capable of encoding a light producing protein or enzyme. Cell death is further mediated by the presence of a photosensitizer which upon photoactivation produces cytotoxicity.
