Fig. 2. Calcium influx triggers ESCRT-III accumulation in plasma membrane during ferroptosis.
(A) Western blot analysis of EIF2AK3 and HSPA5 expression in whole cell extracts in PANC1 cells following treatment with erastin (10 μM) or RSL3 (0.5 μM) for 12 h. (B) Analysis of cytosolic calcium level in PANC1 cells following treatment with erastin (10 μM) or RSL3 (0.5 μM) for 12 h (n = 3, *P < 0.05). (C) Western blot analysis of CHMP5, CHMP6, and SLC7A11 expression in isolated plasma membrane in PANC1 cells following treatment with erastin (10 μM) or RSL3 (0.5 μM) in the absence or presence of PD98059 (10 μM), TUDCA (50 μM), or BAPTA-AM (10 μM) for 12 h.
