Normal human colon mucosal epithelial (FHC) cells and HT29, HCT116, SW480, and SW620 colon cancer cells were purchased from Nanjing KeyGen Biotech Co., Ltd., China. The FHC cells were cultured in RPMI 1640 medium (Gibco, USA) supplemented with 10% foetal bovine serum (FBS, Biological Industries, Israel) and penicillin/streptomycin solution. The HT29 and HCT116 cells were cultured in McCoy’s 5A medium (Keygen Biotech) supplemented with 10% FBS. The SW480 and SW620 cells were cultured in L15 medium (KeyGen Biotech) containing 10% FBS. All the cells were cultured in a cell culture incubator at 37 °C with 5% CO2. All the cells were identified within the past year based on short tandem repeats (STRs) or single nucleotide polymorphisms (SNPs) and were not contaminated with mycoplasma.

Human THP-1 macrophages were stationarily cultured with RPMI-1640 medium (brand: Gibco, item No.: C11875500BT) containing 10% FBS (Gibco, 10099-141), 10 U/mL penicillin and 10 μg/mL streptomycin in a 5% CO2 incubator at 37°C. In the culture process, the cell count was kept at 1×107/culture flask. Next, the sub-cultured THP-1 cells were diluted into 1×106/mL, inoculated in a 35 mm culture dish and cultured in low-serum RPMI-1640 medium containing 100 ng/mL phorbol-12-myristate-13-acetate (PMA) (MCE, HY-18739) and 0.3% BSA to induce their differentiation into M0 macrophages. Furthermore, 10 μm of SHP-2 inhibitors PHPS1 (brand: MCE, HY-112368) and/or 15 ng/mL IL-4 (MCE, HY-P70445) and/or 30 μM of PI3K inhibitors LY294002 (MCE, HY-10108) was added into the medium and incubated for 24 hours. According to experimental requirements, the treated cells were divided into control group, PHPS1 group, IL-4 group, PHPS1+IL-4 group, IL-4+ LY294002 group and PHPS1+IL-4+LY294002 group.
CRC cell lines SW480 and HCT116 were purchased from Nanjing KeyGen BioTech Co., Ltd. After being intervened by PHPS1 and/or IL-4 for 24 hours, macrophages were centrifuged and co-cultured with CRC cell lines SW480 and HCT116. Then, the phenotypes of CRC cells were experimentally observed.

The human CRC cell lines SW620, SW480, HCT-8, 5-FU-resistant HCT-8 cells (HCT-8/5-FU) and LoVo were obtained from KeygenBiotech Co. Ltd. (Nanjing, China), which was recently authenticated as truly CRC cell lines. SW620 and SW480 were cultured in Leibovitz’s L-15 (Gibco, Grand Island, NY) medium contained 10% in activated fetal bovine serum (Gibco, Grand Island, NY). 5-FU was added to LoVo cell culture in stepwise increasing concentrations for over 6 months, namely LoVo/5-FU. HCT-8/5-FU and LoVo/5-FU were maintained in RPMI1640 supplementd with 114.7 μM and 107.0 μM 5-FU, respectively. CRC cells were incubated at 37 °C containing 5%CO2. All cells lines were routinely tested for mycoplasma, which were shown to be negative.

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.
