The Effect of Msh2 Knockdown on Toxicity Induced by tert-Butyl-hydroperoxide, Potassium Bromate, and Hydrogen Peroxide in Base Excision Repair Proficient and Deficient Cells
Figure 3
MTT and clonogenic survival curves for t-BOOH treatment of Mpg +/+ and Mpg −/− MEFs with and without reduced Msh2 expression. MTT (a) and clonogenic survival (b) curves for Mpg +/+ + pshRNAMsh2283, clone 9 (85% Msh2 gene silencing; black square), or Mpg +/+ + pshRNA empty (grey square) cells treated with t-BOOH. MTT (c) and clonogenic survival (d) curves for Mpg −/− + pshRNAMsh2283, clone 1 (79% Msh2 gene silencing; solid square), or Mpg −/− + pshRNA empty (grey square) cells treated with t-BOOH. Results are expressed as mean ± SEM; , , and .
