Abstract BACKGROUND: As alkylating agents, platinum (Pt) analogs kill cancer cells mainly through induction of DNA damage. We hypothesize that low levels of Pt-induced DNA damage are predictive of chemoresistance. Accelerator mass spectrometry (AMS) is an ultrasensitive method for measuring radiocarbon with 10−18∼21 mole sensitivity. By measuring 14C bound to DNA, AMS detects...
264 Background: DNA damage is the critical step in cancer cell response to platinum (Pt) chemotherapy. We hypothesize that low levels of Pt-induced DNA damage are predictive of chemoresistance. Accelerator mass spectrometry (AMS) is an ultrasensitive method for measuring radiocarbon. By measuring 14C bound to DNA, AMS can detect carboplatin-induced DNA damage after patients receive one subtoxic...

2543 Background: DNA damage is the critical step in cancer cell response to platinum (Pt) chemotherapy. We hypothesize that low levels of Pt-induced DNA damage are predictive of chemoresistance. Accelerator mass spectrometry (AMS), an ultrasensitive method for measuring radiocarbon, can detect [14C]carboplatin bound to the DNA of cancer cells from cell culture, mice bearing tumor xenografts and...
