Proteins extracted from BEAS-2B cells and HUVECs were measured using a bicinchoninic acid kit (Beyotime Biotechnology, China). Then, the proteins were resolved on sodium dodecyl sulfate–polyacrylamide gel electrophoresis (10%) and transferred to polyvinylidene fluoride (PVDF) membranes (Millipore, MA, USA). The PVDF membranes were incubated using 5% skimmed milk, and then with primary antibodies at 4 °C overnight. Blots were probed using the following antibodies: anti-IL-1β (1: 1, 000, ab234437; Abcam, Cambridge, UK), anti-TNF-α (1: 1, 000, ab183218; Abcam), and anti-glyceraldehyde-3-phosphate dehydrogenase (anti-GAPDH; 1: 2, 000, bs0755R; Bioss, China), with GAPDH being the endogenous control. Then, membranes were further incubated for 1 h using a secondary antibody (1:2, 000, b-0311P-HRP; Bioss).

The damaged hippocampal region tissues were separated with RIPA buffer (Beyotime, China) on ice and homogenized to extract protein. Forty μg proteins were separated with 12% SDS-PAGE (Bio-Rad, China) and transferred to PVDF membranes (EMD Millipore). After blocking with 5% milk for 1.5 h, the membranes were incubated with appropriate primary antibodies diluted with 5% BSA for overnight at 4 °C. The primary antibodies consisted of phospho-PPARγ (ser273) (1:1000, bs-4888R, Bioss, China), LC3BI/II (1:1000, 4108, Cell signaling technology, China), phospho-NF-κB p65 (1:800, bs-230303R, Bioss, China), GAPDH (1:1000, bs-0755R, Bioss, China). After washing with TBS-0.01% Tween 20 for 3 times (10 min/wash), the secondary antibody Goat Anti-rabbit lgG/HRP (1:1000, bs-0295G-HRP, Bioss, China) was cultured with the membranes for 2 h at 25 °C. After washing, the signals were visualized using enhanced chemiluminescence reagent (D085075, Bio-Rad, China).

Tissues or cell lysates were harvested, and the protein concentrations were detected. Then the proteins were separated using 10% SDS-polyacrylamide gel electrophoresis, transferred onto polyvinylidend difluoride membranes, and blocked and incubated with primary antibodies. Finally, the membranes were incubated with the secondary antibody and visualized by enhanced chemiluminescence (SuperSignal Pierce Biotechnology). The antibodies for western blotting were as follows: CD73 (ab133582, Abcam), p-JNK (#4668, Cell Signaling technology), EGFR (ab52894, Abcam) and GAPDH (bs-0755R, Bioss).

Using RIPA lysis buffer (RIPA; Beyotime Institute of Biotechnology) total protein was extracted from the cells. Using bicinchoninic acid (BCA) method (Pierce; Thermo Fisher Scientific, Inc.) the protein was quantified, and each sample (2 µg) was loaded on 10% gels for SDS-PAGE. The protein was transferred on a polyvinylidene difluoride membrane (Millipore Sigma). Then the membranes were blocked with 5% skimmed milk for ~2 h at room temperature and the membrane was soaked in primary antibodies against pro Caspase-3 (1:1,000; cat. no. ab32150; Abcam), cleaved Caspase-3 (1:500; cat. no. ab32042; Abcam) and GAPDH (1:1,000; cat. no. bs-0755R; BIOSS) at 4˚C for 12 h and secondary antibodies (goat anti-rabbit IgG H&L; 1:1,000; cat. no. bs-0295G; BIOSS) for 2 h at room temperature. Bands were visualized by enhanced chemiluminescence (Amersham ECL; cat. no. RPN3243; Cytiva) and analyzed by ImageJ Software v1.53 (National Institutes of Health).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
