Cell culture
The SKBR-3 cell line was obtained from the American Type Culture
Collection (Manassas, VA), while MDA-MB-231 cells were a kind gift of
Peter Bay (University of Debrecen). The cell lines were selected based
on their different atorvastatin sensitivity (Göbel, Breining, Rauner,
Hofbauer & Rachner, 2019; Kimbung, Lettiero, Feldt, Bosch & Borgquist,
2016; Zhang et al., 2019). Both cell lines were propagated in DMEM
containing 10% fetal bovine serum supplemented with antibiotics. Cells
were harvested at a confluency of 80-90% before measurements.
