YC-1 enhanced the expression of Hsp70 in differentiated PC12 cells.

(A) Effect of YC-1 (0.1–20 µM) on the expression of Hsp70 in differentiated PC12 cells. Differentiated PC12 cells were incubated with different concentrations of YC-1 (0.1–20 µM) for 24 h and the expression levels of Hsp70 were determined by Western blotting. (B) Effect of YC-1 (10 µM) on the time-course changes in the expression of Hsp70 in differentiated PC12 cells. (C) Effect of YC-1 (10 µM) alone and/or with Aβ25–35 (10 µM) on the expression of Hsp70 in differentiated PC12 cells. Differentiated PC12 cells were incubated with YC-1 (10 µM) in the presence of Aβ25–35 (10 µM) for 24 h. All data shown represent the mean ± SD (n = 5). *P#P25–35-treated cells.
