Figure 4. Guanabenz increases sensitivity of Oca2-null melanocytes to thapsigargin.

Figure 4

(a-c) Viability of wildtype and Oca2-null melanocytes after pre-treatment with 50 μM guanabenz for 30 min, followed by either 75 nM thapsigargin treatment or 5 μg/ml tunicamycin for 24 h. Additional doses of 25 μM guanabenz were added at 0 and 6 h of treatment. Average viability ± SEM is shown as percentage compared to vehicle-treated controls (n = 4). *P<0.05.
