The human normal gastric epithelial cell line GES-1 and the GC cell lines AGS, HGC-27, MGC-803, SGC-7901 and BGC-823 were purchased from Genechem (Shanghai, China). GC cell lines with high metastatic potential (MKN-28 M and SGC-7901 M) and corresponding cell lines with low metastatic potential (MKN-28NM and SGC-7901NM) were constructed from the human GC cell lines MKN28 and SGC-7901, respectively, as described previously [3 (link), 4 (link)]. All cells were cultured in RPMI-1640 medium (GIBCO, Carlsbad, CA, USA) supplemented with 10% FBS, 100 U/ml penicillin sodium and 100 μg/ml streptomycin at 37 °C in a 5% CO2 incubator.

Mycoplasma-free Gastric Cell Cultivation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The normal gastric epithelial cell line GES-1 and the GC cell lines AGS, SGC7901, MGC803, and HGC27 were obtained from GeneChem (Shanghai, China). These cells were tested for mycoplasma every month to ensure that they are free of mycoplasma contamination. The method is as follows: the nucleus was stained with DAPI and observed under an oil microscope. Mycoplasma contamination is characterized by radiating or satellite-shaped spots around the nucleus (22 (link)). All cell lines were cultured in RPMI-1640 medium (Corning, Corning, NY, USA), supplemented with 10% fetal bovine serum (FBS) (Clark Bioscience, Richmond, VA, USA), penicillin (100 U/ml), and streptomycin (100 μg/ml) (HyClone, Logan, UT, USA) in a humidified atmosphere at 37°C with 5% CO2. RPMI-1640 medium lacking Asn was customized by Meilun Biotechnology Co. (Dalian, China). For Asn deprivation assays, the cells were plated overnight in complete RPMI-1640 and subsequently transferred into Asn-free medium after a brief wash with phosphate-buffered saline (PBS).

The human GC cell lines HGC27, BGC823, MKN45, SNU-1 and the normal gastric epithelial cell line GES1 were purchased from GeneChem (Shanghai, China), identified by STR profiling and tested free of mycoplasma contamination. All cell lines were cultured in high glucose DMEM (HyClone, Logan, Utah, USA) supplemented with 10% fetal bovine serum (Gemini, Calabasas, CA, USA) and 1% penicillin–streptomycin (Gibco, Grand Island, NY, USA) in a humidified incubator in 5% CO2 at 37 °C.

Gastric Cancer Cell Line Manipulation

Check if the same lab product or an alternative is used in the 5 most similar protocols
A normal human gastric epithelial cell line (GES-1) and three GC cell lines (HGC-27, AGS and MKN-45) were acquired from BNCC (Beijing, China). MKN-45 and HGC-27 cells were cultured in RPIM-1640 medium, AGS cells in DMEM/F-12 medium and GES-1 cells in DMEM medium. All culture media were purchased from Gibco (United States), and were supplemented with 1% penicillin-streptomycin and 10% fetal bovine serum. Genechem (Shanghai, China) provided the green fluorescent protein-labeled miR-204-3p overexpression lentiviral vector (OE group), miR-204-3p knockdown lentiviral vector (KD group) and empty lentiviral vector (NC group), which were then transfected into HGC-27, MKN-45 and AGS cells using the tool virus user manual as a guide.

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.
