Fig. 1

Effect of piperlongumine (PL) on cell viability in MH-S (6 × 105) cells cultured for 48 h with and without PL (2.5–45 μg/mL). Dimethyl sulphoxide (DMSO) was used as internal reference for comparison. Data are expressed as mean ± SD and show no significant differences between DMSO and PL treated cells
