We used GC cell lines, which were obtained from the Japanese Collection of Research Bioresources Cell Bank (Osaka, Japan) as follows: MKN1, MKN45, MKN74, NUGC2, NUGC3, NUGC4, and SC-6-JCK. The GC cell lines AGS, KATOIII, and N87 were purchased from the American Type Culture Collection (ATCC) (Manassas, VA, USA). The human intestinal epithelial cell line FHs74Int (ATCC) served as a nontumorigenic control. Primary GC tissues and corresponding noncancerous mucosal tissues were collected from 200 patients who underwent gastrectomy at Nagoya University Hospital between 2001 and 2014. None of the patients underwent preoperative chemotherapy.
The methods were carried out in accordance with relevant guidelines. The study protocol was approved by the Medical Ethics Committee of the Nagoya University Hospital, protocol No. 2014–0043. Informed consent was obtained from all patients. Written informed consent for the use of clinical samples and data, as required by the Institutional Review Board, was obtained from all patients.

GC cell lines, the differentiated type (AGS, IM95, MKN1, MKN7, MKN74 and N87) and the undifferentiated type (GCIY, KATO-III, MKN45, NUGC2, NUGC3, NUGC4, OCUM1 and SC-6-JCK), were obtained from the Japanese Collection of Research Bio Resources Cell Bank (Osaka, Japan) or the American Type Culture Collection (ATCC, Manassas, VA, USA). A control, non-tumorigenic epithelial cell line (FHs 74) was purchased from the ATCC. The cells were cultured at 37 °C in RPMI medium (Thermo Fisher Scientific, Waltham, MA, USA) supplemented with 10% foetal bovine serum in an atmosphere containing 5% CO2. All cell lines were authenticated using the short tandem repeat PCR method by the Japanese Collection of Research Bio Resources Cell Bank before the study commenced.

Human embryonic kidney (HEK) 293T cells and mouse 3T3 fibroblasts were obtained from the ATCC (https://www.atcc.org). SGC cell lines, KATO‐III and NUGC4, were purchased from Japanese Collection of Research Bioresources (http://cellbank.nibiohn.go.jp/english/). OCUM‐1, ‐2M, ‐8, ‐9 and ‐12 were established by M.Y. All cell lines were maintained in DMEM‐F12 medium supplemented with 10% FBS and 2 mmol/L glutamine (all from Invitrogen).

Human GC cell lines MKN1, NUGC4 (Japanese Collection of Research Bioresources Cell Bank) and AGS (American Type Culture Collection, ATCC) were cultured in Roswell Park Memorial Institute 1640 (RPMI 1640) medium supplemented with 10% fetal calf serum (FCS) and 1% L‐glutamine (Gibco). Cells were authenticated by short tandem repeat profiling (PowerPlex HS16 System kit, Promega), and were passaged for under 6 months after receipt. Cells were routinely tested for mycoplasma contamination (MycoAlert PLUS Mycoplasma Detection Kit, Lonza). AZ521, a duodenal adenocarcinoma line was characterized a Hutu 80 derivative. DNA array data generated from this line was only used as a TLR2 low expressing cell comparison for gene profiling and signaling pathway analysis. No experiment on AZ521 was conducted in our study.

GC cell lines MKN45, NUGC-4, and MKN74 were purchased from the Japanese Collection of Research Bioresources Cell Bank (Osaka, Japan). The cells were exposed to hypoxia (0.1% O2) using a BIONIX system (Sugiyama-gen Co.). Palmitic acid (PA; P9767, Sigma Aldrich, UK) was prepared as 2 mM stock solution by dissolving in 75% ethanol at 70 °C. Stock solutions were then added to 2% FA-free bovine serum albumin (BSA; 017-15146, FUJIFILM, Japan) to achieve the desired final FA concentration. PA or etomoxir (10 mM in dimethyl sulfoxide [DMSO], 124083-20-1, ChemScene, Japan) was added to the medium, and 75% ethanol and DMSO were used as respective controls.

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.
