Commentary on 'resveratrol commonly displays hormesis: occurrence and biomedical significance'.
The review by Calabrese et al. describes the hormetic dose responses induced by phytoalexin resveratrol in a wide range of biological models. We agree and support the authors' strategy to present an impressive number of experiments furnished with an exhaustive bibliography to emphasize that 'many effects induced by resveratrol are dependent on dose and that opposite effects occur at low and high doses, being indicative of a hormetic dose response.' We also highly appreciate the holistic view of the hormetic behavior of resveratrol provided by the authors spanning from tumor and non-tumor cell lines to human and parasitic diseases. In our comments, we touched minor points whose discussion would have strengthened the work of Calabrese, such as contradictions on the role of resveratrol in the 'French Paradox,' its effect on aromatase activity, glutamate cysteine ligase expression and glutathione levels. Overall, we encourage colleagues working in this field to read the present review and consider its relevant biological implications. The vision of Calabrese et al. is far too important to be ignored.
