Total protein extracts were obtained with radioimmunoprecipitation assay (RIPA) lysis buffer (Beyotime) and then quantified by a bicinchoninic acid (BCA) kit (Beyotime). The proteins separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) on a 12% gel were transferred onto polyvinylidene fluoride (PVDF) membranes, followed by being impeded in 5% skimmed milk at room temperature for 2 h. Subsequently, the membranes were incubated with primary antibodies against ENAH (Abcam, 1:1000, ab124685), Ki67 (Abcam, 1:5000, ab254123), proliferating cell nuclear antigen (PCNA) (Abcam, 1:1000, ab92552), SF3B4 (Abcam, 1:2000, ab183483), matrix metallopeptidase 2 (MMP2) (Abcam, 1:1000, ab92536), matrix metallopeptidase 9 (MMP9) (Abcam, 1:1000, ab76003), Notch1 (Abcam, 1:1000, ab52627), hes family bHLH transcription factor 1 (HES1) (Abcam, 1:1000, ab108937), mastermind like transcriptional coactivator 1 (MAML1) (Abcam, 1:1000, ab155786) and GAPDH (Abcam, 1:1000, ab8245) overnight at 4°C and further incubated with HRP-conjugated secondary antibody (Abcam, 1:1000; ab7090) at room temperature for 2 h. The resulting bands were visualized under enhanced chemiluminescence (MilliporeSigma). Protein levels were quantified using Image J software (version 1.46; National Institutes of Health).

Proteins were extracted using radio immunoprecipitation assay lysis buffer (Beyotime Biotechnology). Dodecyl sulfonate polyacrylamide gel electrophoresis Kit (Beijing Dingguo Changsheng Biotechnology) and the polyvinylidene fluoride (PVDF) membranes (Merck) were used to separate the protein, and PVDF membranes were closed with 5% non‐fat powdered milk (Solarbio) for 2 h. The primary antibodies to Bcl2‐associated X (Bax) (ab32503, 1:1000; Abcam), cyclin D1 (2978, 1:1000; Cell Signaling Technology), and ENAH (ab124685, 1:1000; Abcam) and immunoglobulin G secondary antibody conjugated with horseradish peroxidase (HRP) (ab201718, 1:5000; Abcam) were incubated with the membranes. The membranes were added with Immobilon Western Chemiluminescent HRP Substrate (Merck) and photographed in a gel imaging analyzer (UVITEC).

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.
