Estimating the term…
The invention provides compositions, kits, and methods for inducing growth arrest, differentiation, or senescence of cancer cells that express thymine DNA glycosylase, and treating the cancer accordingly. The methods comprise inhibiting expression or biologic activity of thymine DNA glycosylase in cancer cells. Inhibition of thymine DNA glycosylase in cancer cells may induce the cells to revert to a healthy, non-cancerous phenotype and/or may induce the cells to senesce. Cancer cells include melanoma, lung, prostate, pancreatic, ovarian, brain, colon, recto-sigmoid colon, and breast cancer cells.
A method of treating cancer in a patient in need thereof, the method comprising administering to the patient an inhibitor of thymine DNA glycosylase (TDG) in an amount effective to inhibit TDG in cancer cells, wherein the cancer is melanoma, prostate cancer, pancreatic cancer, breast cancer, colon cancer, lung cancer, or glioblastoma, and wherein the inhibitor of TDG is selected from the group consisting of hexadimethrine bromide, indigotindisulfonate, and protamine chloride.
