Gastric Cancer Cell Line Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols
All GC cell lines (BGC823, MGC803, SGC7901, AGS and MKN45) and normal epithelial gastric cells (GES-1) were obtained from Nanjing KeyGen Biotech Co., Ltd. (Nanjing, China). GC cell lines were cultured to 70-80% confluence for subsequent experiments in RPMI-1640 (Gibco; Thermo Fisher Scientific, Inc., Waltham, MA, USA) with 10% fetal bovine serum (Gibco; Thermo Fisher Scientific, Inc.) and 80 U/ml penicillin at 37°C in humidified air containing 5% CO2. To generate higher transfection efficiency and better results in vitro and in vivo, MGC803 and MKN45 cells were chosen to construct miR-3664-5P overexpression- and knockdown-cell lines, respectively, due to the highest miR-3664-5P expression observed in MKN45 cells and the lowest miR-3664-5P expression observed in MGC803 cells.

Inhibiting PI3K in Gastric Cancer

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human gastric cancer cell MGC-803 and the normal gastric epithelial cell line GES-1 were purchased from Nanjing KeyGen Biotech Co., Ltd. The cells were cultured in RPMI-1640 medium with 10% FBS (both purchased from Thermo Fisher Scientific, Inc.), 100 µg/ml penicillin and 100 µg/ml streptomycin at 37°C in a humidified incubator at 5% CO2. The PI3K inhibitor LY294002 (10 mmol/l; Cell Signaling Technology, Inc.) was dissolved in DMSO (cat. no. D2650; Sigma-Aldrich; Merck KGaA) and diluted with RPMI-1640 medium to 12.5, 25 and 50 µmol/l. LY294002 was cultured with MGC-803 cells at 37°C for 24 h in a humidified incubator at 5% CO2.

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.
