Our measurements of the circadian clock in the non-malignant epithelial cell line MCF10A, luminal A (LumA) breast cancer cell line MCF7, and the osteosarcoma U-2 OS cells aligns with prior research (Baggs et al, 2009; Börding et al, 2019; Lellupitiyage Don et al, 2019; Lin et al, 2019), proving the applicability and flexibility of our approach for deep circadian phenotyping across tissue and cancer types. This evidence concerns the gene CLOCK and cancer.
