Abstract
The propensity of a cell to undergo apoptosis has been proposed to be a determinant of sensitivity to anti-microtubule agents. The anti-microtubule agents vincristine and paclitaxel induce key features of apoptosis, such as intranucleosomal DNA fragmentation and changes in nuclear morphology in the human neuroblastoma cell line, NB-39-nu. Nitric oxide (NO) generated from NO-releasing drugs prevented anti-microtubule agent-induced apoptosis in this cell line. The mechanism of suppression of apoptosis by NO appears to be via the inhibition of an interleukin-1beta converting enzyme-like protease cascade. This finding reveals a new biological function of NO, as well as a new molecular insight into resistance to chemotherapy with anti-microtubule agents.Entities:
