Human specimens and cell lines All samples were collected from CRC patients in the First A liated Hospital of Nanjing Medical University.
Their blood samples were also collected before resection on the day of surgery. Besides, a total of 50 cases of human blood samples were obtained from healthy donors. The ethics permission number is 2019-SRFA-131.
Cell lines (HCT 116, HT-29, and HEK293T) were purchased from the Shanghai Institute of Cell Biology and cultured in McCoy'5A and RPMI-1640 medium ( HyClone, Logan) supplemented with 10% FBS.

Human colorectal cancer cells HCT116 and HT-29 were obtained from the Shanghai Institute of Cell Biology (Shanghai, China) and were maintained in DMEM supplemented with 10% FBS plus 2 mM glutamine, 100 U/ml penicillin, and 100 mg/ml streptomycin. Transient transfection of HCT116 cells were transfected with 2 μg of HIBCH plasmid or shHIBCH (sh1: CCATACAGAGTCTAAGATT; sh2: GGTTACTTCCTTGCATTAA) using the Lipofectamine® 3000 (Invitrogen, Carlsbad, CA, USA) reagents by following the manufacturer’s instructions.

Colon Cancer Tissue Collection and Cell Culture

Check if the same lab product or an alternative is used in the 5 most similar protocols
We collected tumor samples and distant normal mucous tissues (>5 cm from the margin of the tumor) from 21 patients with colon cancer who received surgical resection at our hospital from January 2015 to December 2016. No patient had received neoadjuvant chemotherapy or chemotherapy prior to surgery, and all tissue samples were pathologically confirmed. Tumor-node-metastasis staging of the patients was according to the 2015 National Comprehensive Cancer Network clinical practice guidelines. Informed consent was obtained from each patient from the archives of the Central Hospital of Panyu District Hospital and with approval from the institutional ethics committee (Guangzhou, China).
Cell culture FIHC, HCT-116, HT-29, and SW480 cell lines were purchased from the Shanghai Institute of Cell Biology (Shanghai, China). The cell lines were cultured in Dulbecco's Modified Eagle's Medium (DMEM)/Nutrient Mixture F-12 Ham containing 10% fetal bovine serum, and maintained in a humidified incubator at 37°C with 5% CO 2 . The cells in logarithmic growth with 95% viability were subjected to further experiment.

Establishing Oxaliplatin-Resistant Colorectal Cancer Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
Six human colorectal cancer cell lines HCT116, SW480, HT29, SW620, Caco2 and LOVO were obtained from the Shanghai Institute of Cell Biology (Shanghai, China).The related oxaliplatin-resistant cell lines SW480-OxR and HCT116-OxR were generated by continuous exposure to increasing concentrations of oxaliplatin for a 10-month period as described previously 23 (link). We performed cytotoxicity testing to confirm that chemoresistance could be stable for about 4 weeks without oxaliplatin exposure. The oxaliplatin-resistant cell lines were used at no higher than 15 passages from creation. All cells were cultured in the appropriate medium (RPMI-1640 for HT29, SW620, SW480 and SW480-OxR cells; DMEM for Caco2, LOVO, HCT116 and HCT116-OxR cells) supplemented with 10% FBS (Gibco, Carlsbad, CA, USA) in a humidified atmosphere with 5% CO2 at 37 °C.

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.
