Proteins were extracted from renal tissue using an ice-cold lysis buffer, and the protein concentrations were quantified using a BCA assay kit (PC0020; Solarbio). SDS-PAGE was used to separate equal amounts of protein. The blocked membrane was incubated using anti-Bax (1 : 500; WL01637, WanleiBio), anti-P-p53 (1 : 2,000; ab1431, Abcam), anti-PUMA (1 : 3,000; ab9643, Abcam), anti-caspase-3 (1 : 2,000; 9661, CST), anti-Nrf2 (1 : 500; ab89443, Abcam), anti-HO-1 (1 : 500; WL01637, WanleiBio), anti-OCT2 (1 : 500; ab243153, Abcam), anti-MRP2 (1 : 500; ab203397, Abcam), and anti-β-actin (1 : 1,000; WL01372, WanleiBio) antibodies overnight at 4°C. Then, the membranes were incubated with a suitable horseradish peroxidase-conjugated secondary antibody for 60 min at room temperature. Finally, an ECL western blotting substrate was used to visualize the immunoblots.

RIPA lysis buffer (Thermo Fisher) was used to extract proteins from cells and tissues. Serum protein extraction kit (China Qincheng Biological) to extract serum protein. The immune complexes were detected with ECL Western blotting substrate (Thermo Fisher) and developed with BIO-RAD (BIO-RAD Gel Doc XR+). Western blot analysis was performed using standard procedures. The following antibodies (11000) were used: anti-β-actin (Beyotime, AF0003); anti-α-tubulin (Beyotime, AF0001); anti-GAPDH (Beyotime, AF0006); anti-PUF60 (ab22819, Abcam). Anti-IGF2BP1 (ab184305, Abcam); anti-POU2F2 (ab243153, Abcam); anti-HOXA3(ab28771, Abcam). anti-Calnexin (Abcam, ab92573); anti-CD63 (Abcam, ab134045); anti-TSG101 (Abcam, ab125011); anti-CD81 (Proteintech, 66,866-1-Ig).
Perform IHC using standard procedures. Anti-IGF2BP1, POU2F2 and HOXA3 antibodies were used for IHC(Abcam,1: 200). Images were scanned by Pannorama Scan(3DHistech, Hungary). IP was performed with anti-PUF60 antibody (AbCAM, 1:150) and appropriate control IgG(Merck micropore).
Immunoprecipitates were collected by centrifugation and analyzed by SDS-PAGE.

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.
