Review: Sirtuins as mediators of calorie restriction effects in pancreatic β-cells
This review examines evidence that sirtuins mediate pancreatic, especially β-cell, responses to calorie restriction, and discusses links to metabolic homeostasis and healthy longevity. [1]
Automatic summary · not editorially reviewed
The key findings
The review defines calorie restriction as a 30–60% decrease in ad libitum food intake without malnutrition. [1]
SIRT1, SIRT3 and SIRT6 are implicated in preserving β-cell function and enhancing insulin secretion in the pancreas. [1]
The review suggests sirtuins are central molecular links between calorie restriction and β-cell adaptation and may be therapeutic targets. [1]

Calorie restriction and pancreatic β-cells in the review
The review defines calorie restriction as a 30–60% decrease in ad libitum food intake without malnutrition. It states that this has promoted metabolic health and longevity in species including yeast, worms, flies, rodents and perhaps non-human primates, and reduced age-related disorders such as diabetes, cancer and cardiovascular disorders in mammals. The pancreas, particularly insulin-producing β-cells, is described as central to glucose homeostasis and metabolic balance.

Sirtuins SIRT1, SIRT3 and SIRT6 in β-cell function
Sirtuins are described as NAD-dependent deacetylases and ADP-ribosyltransferases that respond to cellular energy status and regulate gene expression, oxidative stress response, mitochondrial function and autophagy. In the pancreas, SIRT1, SIRT3 and SIRT6 are implicated in preserving β-cell function, enhancing insulin secretion and protecting against metabolic stress and inflammation. The review says it integrates experimental findings with emerging clinical evidence on recovery of β-cell function after dietary energy restriction.

Proposed sirtuin link to longevity remains a review hypothesis
The review concludes that available evidence suggests sirtuins are central molecular links between calorie restriction and β-cell adaptation, and highlights their potential as therapeutic targets for preserving pancreatic function and preventing metabolic disease. It also identifies current controversies, limitations and knowledge gaps meant to guide future translational research. These are interpretations and proposals from a review, not demonstrated human lifespan benefits.
