depending upon the conditions , m-amsa enhanced the radiation effect by either a decrease in the survival-curve shoulder or by an increase in slope . m-amsa may act partly by suppressing the accumulation of sublethal damage but , if so , recovery from damage as measured in split-dose experiments with cells pretreated with the drug is not affected to its radiation effect from selective toxicity to cells in a radioresistant phase of the cell cycle can not be excluded .
