The human mammary epithelial cell line (MCF-10A) and the breast cancer cell lines MCF-7 and MDA-MB-231-a (hereafter MDA-MB-231) were purchased from ATCC. The MDA-MB-231-b subclone was kindly provided by Dr. Theresa Guise (24 (link)). MCF-10A cells were cultured in MEGM medium (Lonza) supplemented with 100 ng/ml cholera toxin. MCF-7 cells were cultured in D-MEM high Glucose (Lonza) supplemented with 10% Fetal Bovine Serum (FBS, Atlanta) and 1% Penicillin/Streptomycin (Gibco). MDA-MB-231 cells were maintained in alpha-MEM (Lonza), 10% FBS and 1% Penicillin/Streptomycin. Both cell lines had similar responses to miRNA mimics and were validated at the Vermont Cancer Center DNA Analysis Facility by STR DNA fingerprinting using the Promega GenePrint® 10 System according to manufacturer's instructions (Promega #B9510). The STR profiles were compared to known ATCC fingerprints (ATCC.org), and to the Cell Line Integrated Molecular Authentication database (CLIMA) version 0.1.200808 (http://bioinformatics.istge.it/clima) (25 (link)). The STR profiles of all cell lines matched (>85%) known DNA fingerprints. To collect conditioned medium (CM), MDA-MB-231 cells were seeded at 80% confluence in complete medium. Cells were serum starved for 24 h in 2% FBS prior collection of the CM.

Ovarian cancer cell lines OVCAR4 (NCI, Frederick, MA), TOV21G (Fran Balkwill, Barts Cancer Institute, London, UK), erythroleukemia cell line K562 (Vignir Helgason, University of Glasgow, Glasgow, UK), and human NK cell line NK-92 (ATCC, Manassas, VA) were incubated at 37°C in 5% CO2. OVCAR4 and TOV21G were maintained in DMEM with 10% FBS, 2 mM L-Glutamine, and 100 μg/mL penicillin/streptomycin. NK-92 cells were maintained in MEM-alpha with 12.5% FBS, 12.5% horse serum, 2 mM L-Glutamine, and 5 ng/mL interleukin-2 (IL-2). K562 were maintained in RPMI with 10% FBS plus 2 mM L-Glutamine, and 100 μg/mL penicillin/streptomycin. All lines were tested regularly for mycoplasma infection. All human cancer cell lines were verified by short tandem repeat profiling at the Cancer Research UK Beatson Institute using the Promega GenePrint 10 system (Promega, Southampton, UK). Human NK cells were isolated, resuspended in RPMI with 10% FBS plus 2 mM L-Glutamine and 100 μg/mL penicillin/streptomycin, and used immediately without additional IL-2 or IL-15.

Cell lines ES2 and TOV21G were obtained from the American Type Tissue Collection (ATCC). HCT116 isogenic ARID1A (Q456*/Q456*) and parental lines were purchased from Horizon Discovery (Cambridge, UK). These were developed by knock‐in of a premature stop codon (Q456*). Cell lines were cultured in a humidified 37 °C incubator with 5% CO2. Cell lines were tested to confirm no mycoplasma infection using Mycoalert Mycoplasma Detection Kit as per manufacturer's instructions (Lonza, Slough, UK). Cell line identity was confirmed with short tandem repeat typing using the Promega GenePrint®10 system (Promega, Southampton, UK). Cell pellets were formalin fixed and paraffin‐wax embedded (FFPE) for antibody optimisation.

Establishing 5-FU-Resistant Colorectal Cancer Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
The CRC patient samples were obtained at the First Affiliated Hospital of Sun Yat-sen University and were approved by the institutional review board of the hospital. The study was compliant with all relevant ethical regulations regarding research involving human participants. HCT-8, HCT-116, HEK-293T, and MC38 cells were obtained from the Procell. All cells were cultured in RPMI-1640 or DMEM (Corning, USA) with 10% fetal bovine serum at 37°C in 5% CO2. All cell lines were stored in multiple back up upon receipt to reduce risk of phonotypic drift, and tested with mycoplasma free by Mycoplasma Stain Assay Kit (C0296, Beyotime, China). Cell line authentication was validated by the STR analysis using GenePrint 10 System according to the manufacturer’s instruction (B9510, Promega, USA). 5-FU-resistant HCT-8 and HCT116 cell lines were generated by exposing the cells with 5-FU at 5% of IC concentration for 3 days and gradually increased the concentration by 5% of IC until reaching the IC50.

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.
