Rapamycin-Induced Glucose Intolerance: Hunger or Starvation Diabetes

Open access
Blagosklonny, Mikhail V·2011·Cell Cycle

Abstract

Rapamycin prolongs healthy lifespan in yeast, flies and mammals and delays age-related diseases, including cancer and atherosclerosis. Rapamycin is considered for prevention of diabetic complications, such as retinopathy and nephropathy, and acute treatment with rapamycin decreases insulin resistance. However, under certain conditions, chronic administration of rapamycin may cause glucose intolerance and even provoke type II diabetes. This does not fit logically with its potential effects against diabetic complications. This also seems puzzling, because calorie restriction (CR) can prevent type II diabetes and its complications, and rapamycin mimics CR. It was somehow forgotten that almost two centuries ago, Claude Bernard discovered "starvation diabetes," as shown later, characterized by glucose intolerance, decreased insulin, increased lipoproteins and ketones, gluconeogenesis and hepatic resistance to insulin. This reversible condition is not true diabetes: it does not lead to diabetic complications, and CR extends healthy lifespan. If rapamycin is a CR-mimetic, no wonder it may, in certain models, induce "hunger diabetes." But will rapamycin prevent true type II diabetes? Here are some answers.

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.
