Fig. 6

The protein expression of apoptosis and endoplasmic reticulum (ER) stress genes. The blots were cut prior to hybridization with antibodies in order to focus on the specific protein bands of interest. As a result, we do not have full-length images of the membranes. However, the cropped images accurately reflect the expression of the target protein. Different lowercase letters on the graph bars indicate statistically significant differences among the groups (ANOVA with Duncan’s test, p < 0.05). Data are presented as means ± SEM. The blots were cropped. The samples derived from the same experiment and that blots were processed in parallel. RvD1, Resolvin D1; Tuni, tunicamycin; Tuni + RvD1: co-treatment with RvD1 and tunicamycin; GRP-78, glucose-regulated protein 78; Bcl-2, B cell lymphoma 2; Bax, Bcl-2-associated X protein; GAPDH: glyceraldehyde-3-phosphate dehydrogenase, an internal reference protein
