Sirtuin 1/sirtuin 3 are robust lysine delactylases and sirtuin 1-mediated delactylation regulates glycolysis

open access: yesiScience
Lysine lactylation (Kla), an epigenetic mark triggered by lactate during glycolysis, including the Warburg effect, bridges metabolism and gene regulation. Enzymes such as p300 and HDAC1/3 have been pivotal in deciphering the regulatory dynamics of Kla, though questions about additional regulatory enzymes, their specific Kla substrates, and the ...

The Longevity of Sirtuins

open access: yesCell Reports, 2012
Controversy has recently arisen over the role of sirtuins in metazoan aging. In this issue of Cell Reports, Banerjee et al. demonstrate that Drosophila Sir2 is necessary for life span extension in response to dietary restriction and that its overexpression in the fat body increases the life span.

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

open access: yesBiological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Epigenetics and immunometabolism in diabetes and aging [PDF]

open access: yes, 2018
Significance: A strong relationship between hyperglycemia, impaired insulin pathway and cardiovascular disease in type 2 diabetes (T2D) is linked to oxidative stress and inflammation.

Sirtuins and Pyridine Nucleotides [PDF]

open access: yesCirculation Research, 2012
The silencer information regulator (Sir) family of proteins has attracted much attention during the past decade due to its prominent role in metabolic homeostasis in mammals. The Sir1–4 proteins were first discovered in yeast as nicotinamide adenine dinucleotide (NAD + )-dependent deacetylases, which through a gene ...

Dihydroquinazolinones by Titanocene‐Catalyzed Reductive Radical Addition to Quinazolinones

open access: yesChemistry – A European Journal, EarlyView.
Tri‐ and tetracyclic dihydroquinazolinones or quinazolinones by titanocene catalysis: A highly diastereoselective and efficient reductive radical addition to quinazolinones enables an unprecedented entry to pharmaceutically relevant dihydroquinazolinones by avoiding the interception of radical intermediates prior to the slow radical addition.

Inflammation and premature aging in advanced chronic kidney disease [PDF]

open access: yes, 2017
Systemic inflammation in end-stage renal disease (ESRD) is an established risk factor for mortality and a catalyst for other complications which are related to a premature aging phenotype, including muscle wasting, vascular calcification and other forms ...

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

The effects of sodium–glucose cotransporter 2 inhibitors on the ‘forgotten’ right ventricle

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1045-1058, April 2025.
Abstract With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF).
