Cell lysates were prepared by using a mammalian cell lysis kit (Sigma, USA). The protein expression by western blotting was repeated thrice for each cell line. The following primary antibodies; polyclonal VEGFA, bFGF, TGFβ1 and E-cadherin (Abcam, UK), beta Actin (Bioss, USA) and EGFR (Santa Cruz, USA) were used. Following the peroxidase-conjugated secondary IgG (H + L) (Jackson Immuno Research, USA), immune complexes were visualized using luminol (Bio-Rad, USA). The chemiluminescence from the specific bands was visualized by Molecular Imager GelDoc XR+ ChemiDoc XRS+ Imaging System (BioRad, USA). The expression ratios of VEGFA, E-cadherin, TGFβ1, EGFR, bFGF, and β-actin from the blots were analyzed using Molecular Imager GelDoc XR+ ChemiDoc XRS+ Imaging System and Image Lab Software 6.0.1 (Bio-Rad, USA). After determining the intensities of the obtained bands, normalized protein fold ratios were calculated by proportioning the intensity value of each band to the corresponding β-actin band for each dose level.

The anticancer active peptide used in the present study, anticancer bioactive peptide (ACBP) is a low-molecular-weight active substance that was obtained from the Clinical Medical Research Center, Affiliated Hospital of Inner Mongolia Medical University (Hohhot, China). The poorly differentiated human gastric adenocarcinoma cell line of MKN-45, the highly differentiated human gastric adenocarcinoma cell line NCI-N87 and the immortalized and non-tumorigenic human gastric mucosal epithelial cell line GES-1 were purchased from the Cell Bank of the Chinese Academy of Sciences (Shanghai, China). RPMI-1640 medium and high-glucose DMEM were purchased from Hyclone (Cytiva). Penicillin, streptomycin, fetal bovine serum and 0.25% trypsin were from Gibco (Thermo Fisher Scientific, Inc.).
The Bio-Plex ProT Human Cytokine 27-plex Assay (cat. no. M500KCAFOY; Bio-Rad Laboratories, Inc.) is a multiplex assay that detects cytokines including IL-1β, IL-1RA, IL-2, IL-4, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12, IL-13, IL-15, IL-17, Eotaxin, bFGF, GM-CSF, IFN-γ, MCP-1 (MCAF), IP-10, MIP-1α, PDGF-BB, MIP-1β, RANTES, TNF-α and VEGF. OXA was obtained from Jiangsu Hengrui Pharmaceutical Co., Ltd.

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.
