The collected HUVECs (1 × 105 cells/well) in each group were inoculated into sterile cover glasses in a 6-well plate, respectively. After incubation overnight, HUVECs were fixed by 4% paraformaldehyde (Sigma, St. Louis, MO, USA) and permeated by 0.5%Triton X-100. After sealing with normal goat serum, the HUVECs were exposed with anti-p-TAK1 (1 : 50, Abcam, St. Louis, MO, USA) overnight at 4°C and fluorescent secondary antibody (1 : 100; Abcam, St. Louis, MO, USA) at 37°C for 1 h. After DAPI (Thermo Fisher Scientific, Waltham, MA, USA) nucleation, the fluorescence intensity was observed using a fluorescence microscope (Olympus, CKX41) [29 (link)].

Total proteins were extracted with RIPA lysate from the collected HUVECs in each group, and protein concentration was tested by BCA method (Beyotime, China). Protein samples (40 μg) were separated by 10% SDS-PAGE and transferred to PVDF membranes (Roche). PVDF membranes were blocked with 5% skimmed milk powder at room temperature for 2 h and incubated with primary antibody (dilution ratio: 1∶1000) overnight at 4°C and secondary antibody (dilution ratio: 1∶2000) at 37°C for 2 h. The membranes were addressed with ECL solution (Thermo Fisher Scientific), and the results were acquired with a gel imaging system. p-IRAK1 is referenced by IRAK1, p-TAK1 is referenced by TAK1, and GAPDH was applied as the reference for the other proteins. Anti-interleukin-1 receptor-associated kinase 1 (IRAK1), anti-p-IRAK1, anti-TGF-beta-activated kinase 1 (TAK1), anti-p-TAK1, anti-Bax, anti-caspase 3, anti-mitofusion1 (MFN1), anti-mitofusion2 (MFN2) and anti-opticatrophy1 (OPA1) were all purchased from Abcam (USA) [28 (link)].

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.
