DNA damage-independent apoptosis induced by curcumin in normal resting human T cells and leukaemic Jurkat cells

Curcumin, a phytochemical derived from the rhizome of Curcuma longa, is a very potent inducer of cancer cell death. It is believed that cancer cells are more sensitive to curcumin treatment than normal cells. Curcumin has been shown to act as a prooxidant and induce DNA lesions in normal cells. We were interested in whether curcumin induces DNA damage and the DNA damage response (DDR) signalling pathway leading to apoptosis in normal resting human T cells. To this end, we analyzed DNA ...
