This study describes the sensitization mechanism to thermal stress by histone deacetylase inhibitors (HDACIs) in lung cancer cells and shows that Ku70, based on its acetylation status, mediates the protection of lung cancer from hyperthermia (42.5°C, 1-6 hrs). Ku70 regulates

Sirtuins are protein deacylases with regulatory roles in metabolism and stress response. Functionalized tetrahydro-1H-pyrido[4,3-b]indoles were identified as preferential sirtuin 2 inhibitors, with in vitro inhibitory potencies in the low micromolar concentrations (IC50 3-4 μM) for the more promising candidates. The functional relevance

Nicotinamide, the amide form of vitamin B(3) (niacin), is changed to its mononucleotide compound with the enzyme nicotinic acide/nicotinamide adenylyltransferase, and participates in the cellular energy metabolism that directly impacts normal physiology. However, nicotinamide also influences oxidative stress and modulates

Loss of vascular smooth muscle cell (VSMC) function is a hallmark of vascular disease. VSMCs become increasingly dysregulated, apoptotic, and senescent as we age. Sirtuin 1 (SirT1) is a deactylase that regulates substrates associated with stress mitigation, metabolism, and aging.

Ischemia/reperfusion is a leading cause of liver damage after surgical intervention, trauma, and transplantation. It has been reported that the nicotinamide adenine dinucleotide-dependent deacetylase sirtuin 1 attenuates myocardial, cerebral, and renal ischemia/reperfusion damage. This study aimed to investigate the involvement

The direct conversion of one cell type to another without an intermediate pluripotent stage is required for regenerative therapies. The ventral pancreas and liver share a common developmental origin. Recent studies have shown that hepatocytes could be induced to transdifferentiate

Experimental cell research, 319(10), 1523-1533 (2013-04-23)
The ligand-activated transcription factor peroxisome proliferator-activated receptor-α (PPARα) participates in the regulation of cellular inflammation. More recent studies indicated that sirtuin1 (SIRT1), a NAD(+)-dependent deacetylase, regulates the inflammatory response in adipocytes. However, whether the role of PPARα in inflammation is
