Supporting Information Figure S3. (A) Enlargement of mitochondria of PA-treated SK-MEL-28 melanoma cells. Arrows showing vesicles
accumulated upon PA treatment. Images were acquired using Cellomics ArrayScan HCS Reader. (B) Decrease abundance of COX IV and loss
of MMP in PA-treated SK-MEL-28 melanoma cells. Representative images of three independent experiments were shown. Average fluorescent
intensities of COX IV and MMP dye were quantified using CHP algorithm on the HCS platform. (C) Upregulation of HSPA5 and CHOP protein in
PA-treated SK-MEL-28 melanoma cells. Data are expressed as means ± SEM of three independent experiments. Statistical significance is
expressed as ***, P < 0.001; **, P < 0.01 versus untreated control.
