Influence of overexpression of PDI on thapsigargin-induced cell death of mSOD1 (G93A)-transfected NSC-34 cells. a Transfection with PDI reduced cell death in the presence of thapsigargin in mSOD1 (G93A)-transfected NSC-34 cells. In contrast, SNOC prevented the beneficial effect of PDI. b Cell viability monitored by CCK-8 assay kit. Treatments: G93A or G, mSOD1 (G93A). T thapsigargin, S SNOC, P PDI. Values are mean + SEM, n =4 for each group; *P <0.01, **P < 0.001
