Protein was extracted using SDS lysis buffer and transferred to PVDF membranes. After the membranes were blocked with 5% skim milk for 1 h, they were incubated with primary antibodies overnight at 4 °C, which was followed by incubation with secondary antibodies for 2 h. Bands were visualized using a C-Digit Blot Scanner (Gene Company) and analyzed with ImageJ software. GAPDH (sc-47,724, 1:1000; Santa Cruz) was used as a protein loading control. Primary antibody against eIF4E (sc-9976, 1:500) was purchased from Santa Cruz.

Protease inhibitor cocktail (Roche Applied Science, Mannheim, Germany) containing
50 mM Tris-HCl, 150 mM NaCl, 1% NP-40 and 0.1% sodium dodecyl sulfate (SDS) was
added to the radioimmunoprecipitation assay buffer (pH = 8.0, MedChemExpress).
The protein was extracted by the addition of mixed solution to the cells. The
bicinchoninic acid protein quantification kit (Sigma-Aldrich Chemical Company)
was applied for protein quantification. Proteins were then subjected to 10%
SDS-polyacrylamide gel electrophoresis and transferred to a 0.45 µm
polyvinylidene fluoride membrane (Millipore Corporation, Billerica, MA, USA).
The membrane was sealed for 60 min with 5% bovine serum albumin and probed
overnight with primary antibodies to Cyclin D1 (sc-8396, Santa Cruz
Biotechnology Inc., Santa Cruz, CA, USA), β-catenin (ab22656, Abcam, Cambridge,
UK) and β-actin (sc-81178, Santa Cruz Biotechnology) at 4°C. The secondary goat
anti-mouse antibody (ab205719, Abcam) was used for a 1-h incubation at 25°C. The
immune response was detected using Super Signal West Femto Maximum Sensitivity
Substrate Kit (Thermo Fisher) and C-DiGit Blot Scanner (Gene Company, HK, China)
was used for image acquisition.

Protein was extracted using SDS lysis buffer and transferred to PVDF membranes. After the membranes were blocked with 5% skim milk for 1 hour, they were incubated with primary antibodies overnight at 4°C, which was followed by incubation with secondary antibodies for 2 hours. Bands were visualized using a C‐Digit Blot Scanner (Gene Company) and analysed with ImageJ software. β‐actin (sc1616‐R, 1:1000; Santa Cruz) was used as a protein loading control. The antibodies are listed in Table S1.

Protein was extracted using SDS lysis buffer and transferred to PVDF membranes. After the membranes were blocked with 5% skim milk for 1 h, they were incubated with primary antibodies overnight at 4 °C, which was followed by incubation with secondary antibodies for 2 hours. Bands were visualized using a C-Digit Blot Scanner (Gene Company) and analyzed with ImageJ software. GADPH (1:1000, sc-47724, Santa Cruz) was used as a protein loading control. The following primary antibodies were used: antibodies against eIF4E (1:200, sc-9976) from Santa Cruz, RIPK1 (1:500, ab106393), VE-cadherin (1:500, ab33168), vimentin (1:1000, ab92547), and Snail (1:1000, ab180714) from Abcam (Cambridge, USA), phospho-AKT (S473) (1:500, T40067F) from Abmart, AKT (1:500, #AF6259) from Affinity, E-cadherin (1:1000, #3195) from Cell Signaling Technology, and MMP-2 (1:500, 10373-2-AP) from Proteintech.

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.
