The MCF-7, HCC1937, MDA-MB-231, MDA-MB-468, MDA-MB-453, and SK-BR-3 cell lines were acquired from American Type Culture Collection (Virginia, USA). The MDA-MB-468 with STAT3 overexpression cell line was generously provided by Dr. Liu CY, working in Division of Hematology and Oncology, Department of Medicine, Taipei Veterans General Hospital (Taipei, Taiwan). All cell lines were immediately expanded and frozen down immediately after acquiring. All cell lines could be restarted every 3 months from a frozen vial of the same batch of cells. Cells except for MDA-MB-468 with STAT3 overexpression were maintained as described culture medium by ATCC; MDA-MB-468 with STAT3 overexpression cells was maintained in L-15 medium with G418 700 μg/mL. All media were supplemented with 10% FBS (Caisson, USA), 100 units/mL penicillin, 100 mg/mL streptomycin, and 25 mg/mL amphotericin B (Caisson, USA). All human breast cancer cell lines were incubated in a humidified incubator at 37°C in an atmosphere of 5% CO2 in air.

TMD231 cells were obtained from Dr. Harikrishna Nakshatri in 2009 and are a derivative of the MDA-MB-231 cell line (19 (link)). TMD231 cells were transduced with E2-Crimson lentiviral vector, p2CL7CR2wo, (TMD231-CR) for in vivo imaging as described (20 (link)). Upon receipt, cell stocks were cryopreserved at low passage. Authentication of molecular profiles was verified by short tandem repeat (STR) analysis (IDEXX BioResearch), and cells tested negative for mycoplasma. TMD231 cells were cultured in MEM-α (Gibco) supplemented with 10% FBS (Atlanta Biologicals) and 1% HEPES (Invitrogen). MDA-MB-231, MDA-MB-468, and primary human fibroblast cells were cultured in DMEM (Gibco) supplemented with 10% FBS (Atlanta Biologicals).

The HMLEHRASV12 cell line (HRAS cells), obtained after transforming human mammary epithelial (HMLE) cells with HRAS T24 oncogene, was collected in 2011 from Robert Weinberg (Whitehead Institute, Cambridge, MA, USA), and cultured in DMEM-F12 medium (ATCC) containing 10% fetal bovine serum (FBS) from ATCC. The human breast cancer cell lines MDA-MB-231, HCC1806 and MDA-MB-468 were obtained from ATCC in 2015. ATCC uses the Promega PowerPlex 1.2 system and the Applied Biosystems Genotyper 2.0 software for amplicon analysis. We have not performed any further testing in our lab. MDA-MB-231 and MDA-MB-468 cells were propagated in Leibovitz L-15 medium (ATCC) containing 10% FBS. HCC 1806 cells were propagated in RPMI-1640 media (ATCC) supplemented with 10% FBS, 100 U/ml penicillin, and 100 μg/ml streptomycin. All cell lines were incubated at 37°C in a humidified atmosphere containing 5% CO2, with the exception of the MDA-MB-231 and MDA-MB-468 cells that were grown in the Leibovitz L-15 medium formulation at 37°C in a free gas exchange with 100% atmospheric air.

MDA-MB-231 and MDA-MB-468 cells were cultured in ATCC-formulated Leibovitz’s L-15 medium supplemented with 10% FBS, while MDA-MB-436 cells were grown in the same medium with 10 μg/mL insulin and 16 μg/mL glutathione. All the cells were maintained in a humidified incubator at 37°C with 5% CO2. Cells were passaged by trypsinization after reaching approximately 80%–90% confluence. The detached cells were seeded into a new flask at a density of 2.0 × 103 cells/cm2.
For determination of the effect of cisplatin on TNBC cells, cells were cultured with or without 10, 20, 50, 100, and 200 μM DDP for 24 h or with 10 μM DDP for 24 h and then collected for subsequent experiments.

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.
