‘Treatments based on the phytochemical curcumin have much potential for use in cancer treatments because of their effects on a wide variety of biological pathways, including those regulating the cell division cycle and circadian clocks. Cancer incidence and progression are influenced by circadian clock cells in multiple organs and tissue types. 


‘According to chronotherapeutic studies aimed at optimizing cancer treatments based on the circadian cycle it is known that circadian clocks modify the effectiveness of cancer treatments. Thus, it is important to determine whether curcumin and similar chemotherapeutic treatments being tested against cancer in clinical trials are influenced by the circadian clock. Similarly, it is important to determine whether curcumin alters the timing activity of circadian clock cells. To understand how curcumin treatments and combinatorial therapies using curcumin with standard therapies can be made more effective, we characterized the impact of the circadian clock on the timing of cell death and cell division in curcumin-treated C6 glioma cells.’
