Reactive oxygen species and insulin resistance: the good, the bad and the ugly

Tiganis, Tony·2011·Trends in Pharmacological Sciences

Abstract

Reactive oxygen species (ROS) contribute to the progression of various human diseases, including type 2 diabetes mellitus (T2DM). ROS can suppress the insulin response and contribute to the development of insulin resistance, a key pathological feature of T2DM. Paradoxically, ROS generated by NADP(H) oxidases at the plasma membrane and endomembranes might also be required for normal intracellular signaling. Growth factors, cytokines and hormones such as insulin promote the generation of ROS for the coordinated inactivation of protein tyrosine phosphatases and the promotion of tyrosine phosphorylation-dependent signaling. A recent study has established the potential of H(2)O(2) to enhance insulin sensitivity in vivo and attenuate the development of insulin resistance. Thus, ROS have the capacity to both promote and attenuate the insulin response. Here I review evidence indicating that ROS promote insulin sensitivity versus insulin resistance and discuss the potential complications associated with the widespread use of antioxidants.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
