Provided are nucleic acid-based expression constructs for the targeted production of a therapeutic protein within a cell that is associated with aging, disease, another condition. Also provided are vectors and systems for the delivery of those nucleic acid-based expression constructs as well as methods for using such nucleic acid-based expression constructs, vectors, and systems for reducing, preventing, and/or eliminating the growth and/or survival of an age-, disease-, or condition-associated cell and for the treatment of a disease or condition that is associated with an age, disease, or condition associated cell.
