For vincristine, doxorubicin, erastin2, RSL3, ML162, BSO, and thapsigargin treatments, cell viability was assayed using PrestoBlue. For bortezomib treatment, cell viability was assayed by counting of SYTOX Green+ dead cells. Erastin2, RSL3, ML162, and BSO effects were assayed after 48 h of treatment; doxorubicin and thapsigargin were assayed after 72 h of treatment. Vincristine was assayed after 48 or 72 h of treatment in H1299 and U-2 OS cells, respectively. Data represent means and 95% confidence intervals (in brackets). N.D., not determined.
