Figure 3.p21 mRNA is upregulated in both ferroptosis-sensitive and ferroptosis-resistant cells after treatment with IKE. (A–C) Left panels: Impact of IKE treatment on the mRNA levels of p21. (A) HT-1080 cells were treated for 16 hours while (B, C) H1299 and HCT-116 cells were treated for 48 hours. mRNA levels of ptgs2 and chac1 were measured in (A, B) as markers of ferroptosis. Right panels: the corresponding protein levels in the cells used in the left panels are shown. The data in left panels of (A–C) represent the mean ± SE for three biological replicates with two technical replicates each.
