Abstract
The present invention relates to novel uses of AIM3 acting as a tumor suppressor, and more particularly to methods for using an AIM3 protein or a nucleic acid encoding the protein to activate ATM or ATR and to treat ATM- or ATR-mediated diseases. The AIM3 protein according to the present invention interacts directly with ATM/ATR so as to activate ATM/ATR and proteins regulated by ATM/ATR. Also, the AIM3 protein upregulates tumor suppressor gene p53 and its target genes so as to not only inhibit the proliferation of cells but also to induce apoptosis.
Claims4
A method for inhibiting the proliferation of tumor cells, comprising administering to a cell, tissue or individual an effective amount of an isolated nucleic acid encoding an AIM3 polypeptide having the amino acid sequence shown in SEQ ID NO:
- 1, wherein said cell, tissue or individual comprises tumor cells selected from the group consisting of colon cancer cells, lung cancer cells, leukemia cells, liver cancer cells, breast cancer cells, cervical cancer cells, and prostate cancer cells, wherein the isolated nucleic acid is expressed in the cell, tissue or individual, and wherein the tumor cells have functional p53 or p21.
A method for inhibiting the proliferation of tumor cells, comprising administering to a subject requiring treatment an effective amount of an isolated nucleic acid encoding an AIM3 polypeptide having the amino acid sequence shown in SEQ ID NO:
- 1, wherein said subject comprises tumor cells selected from the group consisting of colon cancer cells, lung cancer cells, leukemia cells, liver cancer cells, breast cancer cells, cervical cancer cells, and prostate cancer cells, wherein the isolated nucleic acid is expressed in the subject, and wherein the tumor cells have functional p53 or p21.
