Regulation of kidney mitochondrial function by caloric restriction.
Serna JDC, Amaral AG, Caldeira da Silva CC, Munhoz AC, Vilas-Boas EA, Menezes-Filho SL, Kowaltowski AJ. Serna JDC, et al. Among authors: kowaltowski aj. Am J Physiol Renal Physiol. 2022 Jul 1;323(1):F92-F106. doi: 10.1152/ajprenal.00461.2021. Epub 2022 May 2. Am J Physiol Renal Physiol. 2022. PMID: 35499238 Free article.
Together, our results highlight the organ-specific bioenergetic, redox, and ionic transport results of CR, with some unexpected deleterious effects in the kidney.NEW & NOTEWORTHY Prevention of obesity through caloric restriction (CR) is well known to protect many tissues but …

Calorie restriction changes muscle satellite cell proliferation in a manner independent of metabolic modulation.
Abreu P, Serna JDC, Munhoz AC, Kowaltowski AJ. Abreu P, et al. Among authors: kowaltowski aj. Mech Ageing Dev. 2020 Dec;192:111362. doi: 10.1016/j.mad.2020.111362. Epub 2020 Oct 1. Mech Ageing Dev. 2020. PMID: 33010305 Free article.
We investigated the effect of rodent calorie restriction on mitochondrial respiration and clonogenic capacity of muscle satellite stem cells, since metabolic alterations are known to regulate stem cell activity. Surprisingly, short or long-term calorie restriction do not c …

Fasting promotes functional changes in liver mitochondria.
Menezes-Filho SL, Amigo I, Luévano-Martínez LA, Kowaltowski AJ. Menezes-Filho SL, et al. Among authors: kowaltowski aj. Biochim Biophys Acta Bioenerg. 2019 Feb 1;1860(2):129-135. doi: 10.1016/j.bbabio.2018.11.017. Epub 2018 Nov 20. Biochim Biophys Acta Bioenerg. 2019. PMID: 30465749 Free article.
In this study we show that overnight fasting (15 h) promotes a shift in the liver mitochondrial bioenergetic profile, with a reduction in ADP-stimulated and maximal respiration, lower membrane potentials and lower resistance to Ca(2+)-induced mitochondrial permeability transition …

Mitochondrial metabolism in aging: effect of dietary interventions.
Cerqueira FM, Kowaltowski AJ. Cerqueira FM, et al. Among authors: kowaltowski aj. Ageing Res Rev. 2013 Jan;12(1):22-8. doi: 10.1016/j.arr.2012.03.009. Epub 2012 Apr 6. Ageing Res Rev. 2013. PMID: 22504406 Review.
Furthermore, dietary interventions used for laboratory animals are often unequal, and of difficult comparison with humans (for whom, by nature, no long-term sound scientific information on the effects of diet on mitochondrial redox state and aging is available). ...

Long-term intermittent feeding, but not caloric restriction, leads to redox imbalance, insulin receptor nitration, and glucose intolerance.
Cerqueira FM, da Cunha FM, Caldeira da Silva CC, Chausse B, Romano RL, Garcia CC, Colepicolo P, Medeiros MH, Kowaltowski AJ. Cerqueira FM, et al. Among authors: kowaltowski aj. Free Radic Biol Med. 2011 Oct 1;51(7):1454-60. doi: 10.1016/j.freeradbiomed.2011.07.006. Epub 2011 Jul 21. Free Radic Biol Med. 2011. PMID: 21816219 Free article.
Short-term calorie restriction and intermittent feeding presented similar results relative to glucose tolerance. Surprisingly, long-term intermittent feeding promoted glucose intolerance, without a loss in insulin receptor phosphorylation. ...

Commonly adopted caloric restriction protocols often involve malnutrition.
Cerqueira FM, Kowaltowski AJ. Cerqueira FM, et al. Among authors: kowaltowski aj. Ageing Res Rev. 2010 Oct;9(4):424-30. doi: 10.1016/j.arr.2010.05.002. Epub 2010 May 20. Ageing Res Rev. 2010. PMID: 20493280
Furthermore, others and we find that every other day feeding, another dietary intervention often referred to as caloric restriction, does not limit the total amount of calories consumed. Altogether, we propose that the term "caloric restriction" should be used specifically …
