HER-2pos SKBR-3, triple negative MDA-MD-468, HER-2pos, trastuzumab resistant HCC1419, and HER-2pos, trastuzumab and lapatinib resistant MDA-MB-453 cell lines were obtained from American Type Culture Collection (ATCC; Rockwell, MA). MDA-MB-468, MDA-MB-453 and HCC1419 cell lines were re-authenticated by ATCC using STR prior to submission. Assays preformed using the SKBR-3 cell line were done within 6 months after the time of purchase from ATCC. Murine TUBO cells were a kind gift from Dr. Wei Zen Wei, (Wayne State University) and were derived from a neu transgenic mouse [45 (link)] and were cultured in RPMI medium. SKBR-3 cells were cultured in McCoy’s 5A Media (Corning, Manassas, VA), MDA-MB-468, MDA-MB-453, and HCC1419 cells were cultured in RPMI-1640 (ATCC). All media was supplemented with 10% v/v fetal calf serum (FBS; Atlanta Biologicals, Flowery Branch, GA), 100 units/ml of penicillin and 100 μg/ml of streptomycin sulfate (BioWhittaker, Walkersville, MD), 2 mmol/L glutamine (BioWhittaker), 1 mmol/L sodium pyruvate (BioWhittaker), and 1% non-essential amino acids (BioWhittaker). All cells were maintained in culture at 37°C in 5% CO2 in a humidified atmosphere.

MCF7, MDA-MB-453, A-431, H1781, H1819, Calu-3, BT-474, SKBR3, and NCI-N87 cell lines were purchased from the ATCC. MCF7, MDA-MB-453, and A-431 were cultured in DMEM; H1781, H1819, Calu-3, and NCI-N87 in RPMI-1640; BT-474 in ATCC HybriCare Medium with 1.5 g/L sodium bicarbonate; SKBR3 in the ATCC-formulated McCoy’s 5a Medium Modified. To make the complete medium, all media were supplemented with 10% FBS and 1% streptomycin/penicillin. All cells used in this study were periodically tested negative for Mycoplasma using the Mycoplasma Plus PCR Primer Kit (Agilent). All patient-derived cancer cells or tumor spheroids in this study were collected and studied according to the Declaration of Helsinki and DFCI IRBs. DFCI 429 was established from a pleural effusion sample. Next-Generation Sequencing confirmed de novo HER2 amplification. DFCI315 and DFCI359 were characterized to harbor HER2 exon20 V777_G778insGSP and HER2 exon19 755_757LREdelinsRP, respectively (23 (link)). Xenograft tumors were processed for short-term ex vivo as previously described (23 (link)). The spheroids in a range of 40 to 70 μmol/L were resuspended in type I collagen (Corning) and loaded into the DAX-1 3-D cell culture chip (AIM Biotech). After solidification, the media were applied to the outer channels with indicated drugs.

Evaluating Vitamin C and PI3K Inhibitors on TNBC Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
TNBC cell lines including BT20 and MDA-MB-453, which both carry activating PIK3CA mutations, were purchased from ATCC (Manassas, VA) in the year of 2018 without further authentication. Frozen cells were newly thawed from low (2-5) passages. Testing for mycoplasma was performed using PlasmoTest Mycoplasma detection kits (Thermo Fisher, Waltham, MA) with only mycoplasma negative cells included in all experiments. BT20 cells were maintained under a 5% CO2 atmosphere in Eagle's Minimum Essential Medium (EMEM), while MDA-MB-453 cells were cultured in Leibovitz's L-15 Medium (ATCC), supplemented with 10% heat-inactivated fetal bovine serum, 100 Units/ ml penicillin, and 100 μg/ml of streptomycin. TNBC cells were seeded for 24 hours and subsequently treated with vitamin C (sodium ascorbate, Sigma-Aldrich, St. Louis, MO) and different PI3K inhibitors at various concentrations. Media was changed daily to ensure the presence of fresh vitamin 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.
