There was a mistake in Figure 1 as published. During the preparation of the figure, an incorrect merged image was inadvertently used for the control (con) group, which resulted in the control group panel not accurately representing the intended experimental condition. The corrected Figure 1 appears below.

FIGURE 1.

Panel A shows the chemical structure of celastrol. Panel B presents a bar graph comparing cell viability percentages across various celastrol concentrations for DMSO and TSZ treatments. Panel C displays a dose-response curve for celastrol, with EC50 of approximately 1.959 micromolar. Panel D shows a bar graph of LDH release (U/L) across celastrol concentrations for DMSO and TSZ. Panel E includes fluorescence microscopy images for live (calcein, green) and dead (PI, red) cells under control, celastrol, TSZ, and combined TSZ plus celastrol conditions, with merged images showing both stains.

Celastrol exhibits anti-necroptotic activity (A) Chemical structure of celastrol (B) HT-29 cells were treated with different concentrations of celastrol, followed by TSZ stimulation for 12 h. Cell viability was measured using the CellTiter-Lumi™ luminescent assay (C) Half-maximal effective concentration (EC50) value calculated based on cell viability results (D) HT-29 cells were pre-treated with various concentrations of celastrol before TSZ stimulation for 12 h. LDH release was measured using an LDH assay kit (E) Representative calcein-AM/PI staining images of HT-29 cells treated with celastrol for 12 h under different conditions. ** P < 0.01, * P < 0.05 versus the TSZ group; ## P < 0.01, # P < 0.05 versus the CON group. N = 3 per group.
