1. A method of reducing viability of a human tumor cell in a subject, comprising the steps of:

  • a. introducing into a human tumor cell in a subject nucleic acid encoding a polypeptide having adenovirus E1A activity;

    b. expressing said polypeptide in an effective amount in the tumor cell, thereby enhancing sensitivity of the tumor cell expressing said polypeptide to a chemotherapeutic agent; and

    c. contacting the tumor cell with said chemotherapeutic agentwherein a nucleic acid encoding functional p53 is not introduced into the tumor cell, said enhanced sensitivity is independent or p53 and viability of the tumor cell is reduced.
