Samples of collected tissues and cultured cells were prepared into a homogenate and centrifuged to collect the protein supernatant. Then, after quantifying protein concentrations by using a BCA assay kit (Pierce Biotechnology, Rockford, IL), an appropriate amount of sample protein was resolved by 10% denaturing SDS-PAGE and transferred onto PVDF membranes (Millipore, Bedford, MA), which were then blocked at room temperature for 1 h by using an Odyssey blocking reagent (Li-Cor, Lincoln, NE), incubated overnight in a 4 °C fridge with anti-SIN3A primary antibodies (ab129087, 1:1000 dilution, Abcam, Cambridge, MA), anti-Arc primary antibodies (ab18950, 1:1000 dilution, Abcam, Cambridge, MA), anti-Egr1 primary antibodies (ab133695, 1:1000 dilution, Abcam, Cambridge, MA), anti-Homer1 primary antibodies (ab184955, 1:1000 dilution, Abcam, Cambridge, MA) and anti-Narp primary antibodies (ab191563, 1:1000 dilution, Abcam, Cambridge, MA) and further incubated with HRP-conjugated secondary antibodies (ab6721, 1:2000 dilution, Abcam, Cambridge, MA). The relative protein expression was analyzed using an Odyssey imaging system (Li-Cor, Lincoln, NE).

Cells were lyzed with lysis buffer (20 mM Tris-HCl [pH 7.5], 150 mM NaCl, 1 mM EDTA, 1% NP40) containing Complete Protease Inhibitor Cocktail (Roche). The cell lysates were separated by standard SDS-PAGE (e-PAGEL, ATTO, Tokyo, Japan) and analyzed by immunoblotting. The following antibodies were used for immunoblotting: anti-PD-L1 (ab213480, Abcam, Cambridge, UK), anti-EGR1 (ab133695, Abcam), anti-c-Myc antibody (Y69) (ab32072, Abcam), goat anti-rabbit IgG (H+L)-HRP Conjugate (Bio-Rad), anti-phospho-p38 antibody (Thr 180/Tyr 182; sc-17852-R, Santa Cruz Biotechnology, Santa Cruz, CA, USA), anti-phospho-SAPK/JNK (Thr183/Tyr185; 81E11, Cell Signaling Technology, Danvers, MA, USA), anti-IκBα mouse antibody (L35A5, Cell Signaling Technology), anti-phospho-IκBα (Ser32/36; 5A5, Cell Signaling Technology), anti-β-actin (C4) (sc-47778, Santa Cruz Biotechnology), and anti-β-actin-HRP (AC-15) (ab49900, Abcam). The Western HRP Substrate (Pierce ECL Western Blotting Substrate, Thermo Fisher Scientific) was used for the development of positive signals, and chemiluminescence was detected using a ChemiDoc XRS+ System (Bio-Rad, Hercules, CA, USA).

Cell lysate derived from Hep3B or Hep3B/So was prepared using lysis buffer (PBS + 1% NP40 + 0.1% SDS + 5 mmol/L EDTA + 0.5% sodium deoxycholate + 1 mmol/L sodium orthovanadate), and protein concentration was determined by BCA Assay Kit (ThermoScientific). 40 μg protein samples were separated on 10% SDS‐PAGE and then electrotransferred onto PVDF membrane, which was blocked by 5% skimmed milk at room temperature for 1 hour Next, the membrane was incubated with the primary antibodies LC3I (GTX17380, 1:1000; GeneTex) and LC3II (GTX127375, 1:3000; GeneTex), EGR1 (ab133695, 1:1000; Abcam) at 4°C overnight. The membrane was rinsed in TBST solution and then incubated with the secondary goat anti‐rabbit antibody (ab205718, 1:5000; Abcam) for 2 hours. The signal was determined using enhanced ECL (Perkin Elmer) by ImageQuant LAS 4000 (ImageQuantTL, Imagemoster 2D Platinum 6.0; GE Healthcare Life Science).

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.
