Compositions and a method are provided for the treatment of prostate and other endocrine tumors in mammals, including humans, by administration of an antisense oligodeoxynucleotide (ODN) which is complementary to a portion of the gene encoding IGFBP-2. Using the Shionogi tumor model in vitro and in vivo, the administration of such an ODN was shown to reduce proliferation of tumor cells, and also to delay the progression to androgen independence. Thus, treatment of prostate and other hormone-regulated cancer in mammals, including humans, and delay of the progression of prostate tumors to androgen independence is accomplished by administering to the mammal a therapeutically effective amount of an antisense oligodeoxynucleotide which is complementary to a portion of the nucleic acid sequence encoding IGFBP-2 and which reduces the amount of IGFBP-2 in the treated cells. |
