Combining chemotherapy with AZT may eradicate certain cancers
New research suggests that combining the chemotherapy drug paclitaxel with very low doses of the HIV-fighting drug AZT may shrink or even eradicate certain types of cancer tumors. Using both drugs in mice helped inhibit the enzyme telomerase, a component critical to the livelihood of some cancer cells. Telomerase helps to build and maintain telomeres ? protective strands of DNA at each end of a chromosome.
