Abstract:
Administration of antisense oligodeoxynucleotides (ODN) targeted against the testosterone-repressed prostate message-2 (TRPM-2) gene can reduce the amount of TRPM-2 in renal cell cancer (RCC) cells and other cancer cells, and as a result enhance chemosensitivity of these cells to chemotherapy agents and radiation. Thus, for example, the sensitivity of renal cell cancer cells to a chemotherapeutic agent can be increased by exposing renal cell cancer cells to a chemotherapeutic agent and an agent which reduces the amount of TRPM-2 in the renal cell cancer cells. This provides an improved method for treatment of renal cell cancer, which is generally resistant to treatment with known chemotherapy agents.

Abstract:
It has now been determined that antisense therapy which reduces the expression of TRPM-2 provides therapeutic benefits in the treatment of cancer. In particular, such antisense therapy can be applied in treatment of prostate cancer and renal cell cancer. Addition of antisense TRPM-2 ODN to prostatic tumor cells in vivo is effective for delaying the onset of androgen independence. Thus, prostate cancer can be treated in an individual suffering from prostate cancer by initiating androgen-withdrawal to induce apoptotic cell death of prostatic tumor cells in the individual, and administering to the individual a composition effective to inhibit expression of TRPM-2 by the tumor cells, thereby delaying the progression of prostatic tumor cells to an androgen-independent state in an individual Combined use of antisense TRPM-2 and taxanes synergistically enhances cytotoxic chemosensitivity of androgen-independent prostate cancer. In addition, it has also been found that antisense TRPM-2 has beneficial effect for other cancer types. Specifically, antisense TRPM-2 ODN enhances chemosensitivity in human Renal cell cancer, a normally chemoresistant disease with no active chemotherapeutic agent having an objective response rate higher than 10%. Radiation sensitivity is also enhanced when cells expressing TRPM-2 are treated with antisense TRPM-2 ODN. Thus, the antisense TRPM-2 ODNs can be used to enhance hormone sensitivity, chemosensitivity and radiation sensitivity of a variety of cancer types in which expression of TRPM-2 has been observed.

It has been determined that antisense therapy which reduces the expression of TRPM-2 provides therapeutic benefits in the treatment of cancer, particularly prostate and renal cell cancers. Addition of antisense TRPM-2 ODN to prostatic tumor cells in vivo is effective for delaying the onset of androgen independence, thus prostate cancer can be treated by initiating androgen-withdrawal to induce apoptotic cell death of prostatic tumor cells in an individual, and administering a composition effective to inhibit expression of TRPM-2 by the tumor cells. Combined use of antisense TRPM-2 and taxanes synergistically enhances cytotoxic chemosensitivity of androgen-independent prostate cancer and in human Renal cell cancer. Radiation sensitivity is also enhanced when cells expressing TRPM-2 are treated with antisense TRPM-2 ODN. Thus, the antisense TRPM-2 ODNs can be used to enhance hormone sensitivity, chemosensitivity and radiation sensitivity of a variety of cancer types in which expression of TRPM-2 has been observed.
