Abstract：
:The lithocholic acid-sensitive mutant cells were isolated from CHO-9 cells mutagenized with ethylmethane sulfonate, through clonal selection on 96-well dishes. The isolated mutant cells (LSJ-11) were 3-fold more sensitive than controls in the survival to lithocholic acid and were also sensitive to other bile acids such as deoxycholic acid and cholic acid. As a preliminary characterization, it was found that the mutant cells were also sensitive to cytoskeleton-disturbing agents such as colchicine, colcemide, taxol and cytochalasin B. This is the first observation that a bile acid-sensitive mutant was isolated and was partially characterized.
