All cells were lysed in 1% NP40 buffer (150 mM NaCl, 50 mM Tris-HCl pH 8, 10% glycerol, 2 mM EDTA) supplemented with 1 mM cOmplete Mini protease inhibitors (Roche) and 1 mM sodium orthovanadate (ThermoFisher). Proteins were separated on a 4–20% SDS-PAGE gel (BioRad) and transferred to polyvinylidene difluoride (PVDF) membrane. Membrane was incubated in 5% BSA and 0.1% Tween-20 in PBS for 1 hr, incubated overnight at 4°C with primary antibodies (1:10000 anti-β-actin, Santa Cruz #sc-47778; 1:1000 anti-SHC, BD Transduction #610878; 1:1000 anti-ERK, Invitrogen #13–6200; 1:1000 anti-phospho-SHC (Tyr239/240), Cell Signaling #2434; 1:2000 anti-phospho-p44/42 ERK (Thr202/Tyr204), Cell Signaling #4370; 1:1000 anti-EGFR, Cell Signaling #2232; 1:700 anti-phospho-Thr/Tyr, Cell Signaling #9381; 1:500 anti-CLDN1, Invitrogen #37–4900; 1:350 anti-OCLN, Invitrogen #33–1500), then incubated for 1 hr at room temperature with horseradish peroxidase-conjugated secondary antibodies (1:10000 anti-rabbit, Cell Signaling #7074; 1:10000 anti-mouse, Cell Signaling #7076). Membrane was added SuperSignal West Pico PLUS Chemiluminescent or West Femto Maximum Sensitivity substrate (ThermoFisher) and exposed to CL-XPosure film (ThermoFisher).

Liver tissues were homogenized in the lysis buffer (MilliporeSigma) containing protease and phosphatase inhibitors (MilliporeSigma). Thirty micrograms of proteins were separated proteins subjected to 4%–20% SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and transferred onto nitrocellulose membranes. After blocking, the membranes were probed with primary antibodies as indicated at 4°C overnight, then with fluorescence conjugated secondary antibodies (LI-COR) for 1 h at room temperature. Images were visualized and analyzed using Odyssey CLx Imaging System (LI-COR).
To detect phospho-Shc and Shc in PBMC, automated Western blot analysis was conducted using the Jess™ capillary western system (ProteinSimple) following the instructions. Total 0.75 μg of protein was separated and immobilized in electrophoretic capillaries provided by the manufacturer. Primary antibodies (1:50 to 1:100) were applied for 1 h. After probing with appropriate secondary antibodies for another hour, the signal was acquired and quantified with Compass software (ProteinSimple).
Anti-phospho-Shc (Tyr239/240), and anti-Shc were from Cell Signaling Inc.; anti-β-Actin was from R&D Systems.

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.
