Human breast cancer cell lines MCF7, MDA-MB-468, MDA-MB-231, HCC70, and SK-BR-3 and normal human mammary epithelial cell MCF10A were purchased from American Type Culture Collection (ATCC). We have authenticated all the cell lines by short tandem repeat technology (Genetica DNA Laboratories). Cells were tested for mycoplasma using the Universal Mycoplasma Detection Kit from ATCC. Cells were maintained at 5% CO2 in a 37 °C humidified incubator. MCF7, MDA-MB-468, MDA-MB-231, and HCC70 cells were grown in DMEM (Invitrogen) and supplemented with 10% FBS (Gemini). SK-BR-3 cells were cultured in McCoy’s 5a Medium and supplemented with 10% FBS (Gemini). MCF10A cells were grown in MEGM Mammary Epithelial Cell Growth Medium SingleQuots Kit without gentamycin–amphotericin B mix (Lonza) with 100 ng/mL cholera toxin. All cells were supplemented with 50 U/mL penicillin, 50 μg/mL streptomycin (Mediatech), and 5 μg/mL plasmocin (InvivoGen). MDA-MB-468 shp53 cells generated with mir30 short hairpin RNA can induce knockdown of mtp53 with 8 μg/mL doxycycline for 7 days.3 (link),16 (link)

The basal‐like breast cancer cell lines MDA‐MB‐468, HCC70, HCC38, the luminal breast cancer line MCF7, and the human embryonic kidney (HEK) 293T cells were originally obtained from the American Type Culture Collection (USA). MDA‐MB‐468, HCC70, HCC38, and MCF7 were grown in RPMI, while HEK293T cells were grown in Dulbecco's modified Eagle medium (DMEM) (Gibco BRL, USA). Unless otherwise indicated, all cell lines were cultured in a medium containing 10% fetal bovine serum (Gibco BRL, USA), L‐Glutamine (2 mM), and penicillin/streptomycin. Cells were cultured at 37 °C in a humidified incubator of 5% CO2. Cell lines were routinely (once a month) checked for mycoplasma using an RT‐PCR.

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.
