Cells were lysed in RIPA buffer and total protein was extracted. Then, the protein concentration was determined by BCA assay. A 10% SDS-PAGE gel (Asegene, Guangzhou, China) was loaded with 20 μg of total protein, and the separated proteins were transferred by electroblotting to PVDF membranes. The membranes were blocked with 5% nonfat dry milk in TBST (50 mM Tris, pH 7.6, 150 mM NaCl, and 0.1% Tween 20) and then incubated with the primary antibody overnight at 4°C. Antibodies included anti-Fut9 (ab176794; 1:500; Abcam, Cambridge, UK), anti-NF200 (18934-1-AP; 1:1000; Proteintech, Chicago, USA), anti-β3-tubulin (ab18207, 1:1000; Abcam), anti-MAP2 (AF4081; 1:1000; Affinity Biosciences, Cincinnati, USA), anti-Hes1 antibody (ab108937; 1:1000; Abcam), anti-Hes5 antibody (ab194111; 1:1000; Abcam), anti-β-tubulin (ab179511; 1:1000; Abcam), and anti-GAPDH (AF7021; 1:1000; Affinity Biosciences). Blots were washed three times with TBST for 5 min each time, and membranes were incubated with HRP-conjugated goat anti-rabbit IgG antibody (ab6721; 1:5000; Abcam) for 1 h at 25°C. Then, the protein bands were visualized with Immobilon Western Chemiluminescent HRP Substrate (Sigma-Aldrich, St Louis, USA).

Differential Gene Expression in CRC

Our in‐house CRC cohort included 37 pairs of fresh CRC tumor and adjacent normal tissue specimens without radiotherapy or chemotherapy, which were immediately stored in liquid nitrogen after surgery (Table S1). All specimens were collected from Zhengzhou Central Hospital Affiliated to Zhengzhou University between 2019 and 2020 and this study was approved by the Zhengzhou Central Hospital Affiliated to Zhengzhou University. All patients had undergone rigorous screening and underwent informed consent.
qRT‐PCR was employed to detect the RNA levels of CEBPB, ENO1 and β‐Actin. Table S2 lists the involved primer sequences. Table S3 shows the relative expression level of CEBPB and ENO1 mRNA in 37 pairs of CRC tumors and matched to adjacent normal samples. Western blotting was used to detect the protein levels of corresponding genes in 10 pairs of tumors and the matched adjacent normal samples from our center. Primary antibodies used in this study included anti‐β‐Actin (Proteintech, HRP6008), anti‐β‐Tubulin (Abcam, ab179511), anti‐CEBPB (Abcam, ab32358), and anti‐ENO1(CST, 3810T). Table S4 shows the relative expression levels of CEBPB and ENO1 proteins in 10 pairs of CRC tumors and the matched adjacent normal samples (see more in Appendix S1).

Comprehensive Protein Expression Analysis

Total protein was extracted using RIPA buffer (Thermo Fisher Scientific, Waltham, MA, USA) and detected utilizing BCA assay (Thermo Fisher Scientific, Waltham, MA, USA). 30 µg of protein per sample was separated by SDS‐PAGE, and then transferred onto PVDF membrane (Gene Molecular Biotech, Inc., Shanghai, China). After obturated with 5% milk for 2 h at room temperature, the membrane was incubated overnight at 4 °C with primary antibodies as follow: COX6C (2 µg mL−1, Abcam, ab110267), DHRS2 (0.1 µg mL−1, Abcam, ab220483), β‐Catenin (1:5000, Abcam, ab32572), Vimentin (1:1000, Abcam, ab92547), E‐cadherin (1:10 000, Abcam, ab40772), Snail (1:1000, Abcam, ab216347), and β‐tubulin (1:1000, Abcam, ab179511). Afterward, the membrane was incubated with HRP‐conjugated goat anti‐rabbit IgG secondary antibodies (1:7500, Abcam, ab205718) or HRP‐conjugated goat anti‐mouse IgG secondary antibodies (1:7500, Abcam, ab205719) for 1 h at room temperature, the expression level was measured with an ECL kit (Roche Diagnostics, Basel, Switzerland) by Western blot imaging system.

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.
