To detect HER2 expression, HIBEC, RBE, HuccT1, CCLP1, HGBEC, SGC-996, NOZ, GBC-SD, and EH-GB1 cells were seeded in 6-well plates at the density of 4 × 105 per well. After 48 h, the total protein of each cell line was extracted. For mechanism validation, GBC-SD and EH-GB1 cells were seeded in 6-well plates at the density of 4 × 105 per well until adherent and replaced with different media. Each cell line was also divided into 8 groups and treated as previously described for the cell proliferation assay. After 48 h, total protein was extracted from each cell group. Then western blotting was performed according to the standard methods. The following antibodies, Rabbit monoclonal anti-HER2 (Abcam, Catalog no. ab134182, 1:1000 dilution), Mouse monoclonal anti-GAPDH (Abcam, Catalog no. ab8245, 1:5000 dilution), Rabbit monoclonal anti-NFκB p65 (Abcam, Catalog no. ab32536, 1:10,000 dilution), Rabbit monoclonal anti-NFκB p50 (Abcam, Catalog no. ab32360, 1:10,000 dilution), Mouse monoclonal anti-beta actin (Abcam, Catalog no. ab8226, Use a concentration of 1 µg/ml), and Rabbit polyclonal anti-Lamin B1 (Abcam, Nuclear Envelope Marker, Catalog no. ab16048; Use a concentration of 0.1 µg/ml) were obtained from Abcam.

Protein lysates were prepared as described (Lener et al., 2009 (link)). Appropriate amounts of protein were separated by SDS-PAGE electrophoresis and transferred to PVDF membranes as described (Greussing et al., 2013 (link)). Proteins of interest were detected by incubating the membranes with appropriate antibodies. Following primary antibodies were used: monoclonal mouse anti-p53 (#SC-126 Santa Cruz Biotechnology, USA), polyclonal rabbit anti-Lamin B1 (#ab16048 Abcam, United Kingdom), monoclonal rabbit anti-p21 waf1/cip1 (#2947S Cell signaling technology, USA), polyclonal rabbit anti-pp53 (Serin15) (#9284S Cell signaling technology, USA), and monoclonal mouse anti-GAPDH - glyceraldehyde 3-phosphate dehydrogenase (GAPDH) (#SC-25778 Santa Cruz Biotechnology, USA). Appropriate polyclonal HRP-conjugated secondary antibodies were used (Dako Cytomation, Denmark). Detection was performed in a ChemiDoc Imaging system (Bio-Rad Laboratories, USA) using a chemiluminescence substrate kit (Merck Millipore, Germany). As positive controls protein lysates obtained from HDFs at passage 35 and Cisplatin-treated HDFs (33 μM) were used. Results were normalized to the loading control. Analysis of densitometry was performed in ImageJ software and the values were normalized to the loading control (GAPDH).

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.
