Figure Lengend Snippet: Figure 2. Protein expression levels involved ferroptosis were detected in the liver tissues of mice challenged with CCl4. (A) Protein expression levels of ALOX12, HO-1, COX-2, p21 and Nrf2 at 6 and 24 h identified by Western blotting analysis of liver tissues of mice treated with CCl4; the quantitative analysis is showed in (B) (n = 4). 6 h vs. ctrl, * p < 0.05, ** p < 0.01; 24 h vs. ctrl, # p < 0.05, ## p < 0.01. Ctrl: control.

Article Snippet: The following primary antibodies were used to probe the membranes: primary rabbit antibodies against p21 (1:1000), COX2 (1:1000), Nrf2 (1:1000), and HO-1 (1:1000) (ProteinTech Group, Inc., Chicago, IL, USA), mouse monoclonal antibody against ALOX12 (1:1000) (Abcam, Cabridge, MA, USA) and β-actin (1:1000) (Santa Cruz Biotechnology, Dallas, TX, USA).

Techniques: Expressing, Western Blot, Control

Article Title: Sterigmatocystin-induced DNA damage triggers G2 arrest via an ATM/p53-related pathway in human gastric epithelium GES-1 cells in vitro.

doi: 10.1371/journal.pone.0065044

Figure Lengend Snippet: Figure 4. The p53-p21 pathway is activated in ST-treated GES-1 cells. GES-1 cells were treated with different concentrations of ST (0.075, 0.3, 1.5, and 3 mM) or solvent for 48 h. (A) Representative immunoblots show the effect of ST treatment on the phosphorylation of p53 (Ser-15) and the expression of p53 and p21. b-actin was used as the normalization control. (B) Intensities of the immunoreactive bands were quantified by densitometric scanning and compared with those of the control (considered ‘‘1’’). The values shown represent the means 6 SD. *P,0.05 compared with the solvent-treated control group. doi:10.1371/journal.pone.0065044.g004

Figure Lengend Snippet: Figure 6. Silencing of p53 by specific p53 siRNA inhibited ST-induced G2 arrest. Cells were either not transfected or transfected with 100 nM p53 siRNA and then treated with 3 mM ST for 48 h. (A) Cells were subjected to immunoblot analysis for p-p53 (Ser15), p53, p21, and (C) the regulators related to G2 arrest. NC: cells transfected with the same concentration of negative control siRNA. b-actin was used as the loading control. (B, D) Intensities of the immunoreactive bands in ‘‘A’’ and ‘‘C’’ were quantified by densitometric scanning and compared with those of the control (considered ‘‘1’’). (E) The cell cycle phases of the cells were analyzed by FCM. The values shown represent the means 6 SD, *P,0.05 compared with the solvent-treated control group. mP,0.05 compared with the ST-treated groups. #P,0.05 compared with the p53 siRNA-treated groups. doi:10.1371/journal.pone.0065044.g006
