Cytotoxic effects of Bcl-xL DNAzymes on SW837 cells. SW837 cells were treated with different DNAzymes targeting Bcl-xL, DT867, DT880, DT882, DT883, and DT884, for 48 h. Cell viability was detected by MTT method. A scrambled DNA sequence was used as a negative control. n = 3. Data were presented as the mean ± SD. *P<0.05, **P<0.01 vs. 0 µM. NC, negative control
