Rabbit anti sod1

We followed the methods of Manchini et al. [32 (link)] and Melo et al. [33 (link)] for the muscle tissue processing and for protein extraction. Protein samples (20 μg) were subjected to SDS-PAGE in 10–12% polyacrylamide gel. Separated proteins were transferred onto hydrophobic membranes (Hybond-P, Amersham Biosciences; Piscataway, NJ, USA), in which they were soaked in a blocking buffer (5% nonfat dry milk and 0.1% Tween 20 in PBS, pH 7.5) for 60 min at room temperature and then incubated overnight at 4°C with primary antibodies: rabbit anti-4-HNE (1 : 2000 dilution; Abcam, Cambridge, MA, USA); rabbit anti-SOD1 (1 : 5000 dilution; Abcam, Cambridge, MA, USA); rabbit anti-CAT (1 : 5000 dilution; Abcam, Cambridge, USA); goat anti-HSP70 (1 : 1000; Abcam, Cambridge, MA, USA); and anti-GAPDH (1 : 500; Santa Cruz Biotechnology, Santa Cruz, CA, USA). Then, membranes were washed five times and incubated for 60 min with horseradish peroxidase-conjugated goat anti-rabbit and rabbit anti-goat secondary antibodies (1 : 2000; Invitrogen, San Diego, CA, USA). Membranes were washed five times again with blocking buffer and then rinsed twice in PBS buffer. Bound antibody was detected by using chemiluminescence reagent for 60 s. The bands were imaged by using Amersham Imager 600 system (GE Health Care, Little Chalfont, UK, USA).

Total proteins were obtained from liver tissues adjacent to the cancer region by a protein extraction kit (Beyotime, China). Protein samples were then separated using 12% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and transferred onto nitrocellulose membranes. Membranes were blocked with 5% skim milk in TBST and incubated overnight at 4°C with the following primary antibodies: rabbit anti-PPAR-α (1:1,000, #ab24509, Shanghai, China), rabbit anti-SOD1 (1:1,000, Abcam Biotechnology, UK), rabbit anti-SOD2 (1:1,000, Abcam Biotechnology, UK), rabbit anti-Bcl-2 (1:1,000, #12789-1-AP, Wuhan, China), and rabbit anti-β-actin (1:1,000, Abcam Biotechnology, UK). On the following day, membranes were incubated with horseradish peroxidase-conjugated goat-anti-rabbit secondary antibodies (Boster Biological Technology, Wuhan) at room temperature for 2 h. An enhanced chemiluminescence (ECL) reagent (Thermo Fisher) was used to visualize the immunoreactive proteins. Signal densitometry was quantified by software analysis (Quantity One, Bio-Rad, USA).
