1. A method for increasing the sensitivity of a neoplastic cell to a chemotherapeutic agent comprising:
reducing the expression level of a nucleic acid encoding c-Myb or the expression level of c-Myb protein in the cell or reducing activity of c-Myb protein by contacting the cell with a sufficient amount of an isolated nucleic acid to increase the sensitivity of said cell to said chemotherapeutic agent, wherein said isolated nucleic acid comprises at least 16 consecutive nucleotides having a sequence that is at least 90% identical to a sequence encoding c-Myb or complement thereof, wherein said isolated nucleic acid is selected from a small hairpin RNA (shRNA), a small interfering RNA (siRNA), a micro RNA (miRNA), an antisense polynucleotide, and a ribozyme, wherein the cell is selected from the group consisting of a prostate cancer cell, a castration-resistant prostate cancer cell, and an androgen-dependent prostate cancer cell; and contacting the cell with an effective amount of the chemotherapeutic agent, wherein the effective amount is sufficient to inhibit the growth of the cell, wherein the effective amount is reduced compared to the effective amount for a cell wherein the level of a nucleic acid encoding c-Myb or a fragment thereof or the level of c-Myb protein or a fragment thereof or the activity of c-Myb protein is not reduced.
