Identification of circadian-related gene expression profiles in entrained MCF7

ABSTRACT: Cancer cells have broken circadian clocks as compared to their normal tissue counterparts. Moreover, it has been shown in breast cancer that disruption of common circadian oscillations are associated to worse prognosis. Numerous studies focused at conical circadian genes in breast cancer cell lines have suggested that there are no mRNA circadian-like oscillations. Nevertheless, cancer cell lines have not been extensively characterized and it is unknown to what extent the circadian oscillations are disrupted. We have chosen representative breast cancer cell lines (MCF-10A, MCF-7, ZR-75-30, MDA-MB-231, and HCC-1954) in order to determine the degree which the circadian clock is damaged. We used serum shock to synchronize the circadian clocks in culture. Our aim was to observe the time course
