Hsp70 is necessary for KU-596 to improve mtBE in ex vivo diabetic neurons. Effect of treatments on MRC and SRC. ND, nondiabetic. *, p < 0.003 and 0.004 versus ND-MRC and ND-SRC, respectively; #, p < 0.001 and 0.002 versus MRC and SRC from ND + KU-596, respectively. Symbols are responses from pooled neurons in each well that were isolated from lumbar DRG of 3–6 mice per group.
