The overexpression of major antioxidant enzymes does not extend the lifespan of miceAging Cell - Tập 8 Số 1 - Trang 73-75 - 2009
Viviana Pérez, Holly Van Remmen, Alex Bokov, Charles J. Epstein, Jan Vijg, Arlan Richardson
SummaryWe evaluated the effect of overexpressing antioxidant enzymes on the lifespans of transgenic mice that overexpress copper zinc superoxide dismutase (CuZnSOD), catalase, or combinations of either CuZnSOD and catalase or CuZnSOD and manganese superoxide dismutase (MnSOD). Our results show that the overexpression of these major antioxidant enzymes, which are kn...... hiện toàn bộ
NK and NKT cell functions in immunosenescenceAging Cell - Tập 3 Số 4 - Trang 177-184 - 2004
Eugenio Mocchegiani, Marco Malavolta
SummaryImmunosenescence is defined as the state of dysregulated immune function that contributes to the increased susceptibility to infection, cancer and autoimmune diseases observed in old organisms, including humans. However, dysregulations in the immune functions are normally counterbalanced by continuous adaptation of the body to the deteriorations that occur o...... hiện toàn bộ
Age‐associated loss of Sirt1‐mediated enhancement of glucose‐stimulated insulin secretion in beta cell‐specific Sirt1‐overexpressing (BESTO) miceAging Cell - Tập 7 Số 1 - Trang 78-88 - 2008
Kathryn Moynihan Ramsey, Kathryn F. Mills, Akiko Satoh, Shin‐ichiro Imai
SummaryThe Sir2 (silent information regulator 2) family of NAD‐dependent deacetylases regulates aging and longevity across a wide variety of organisms, including yeast, worms, and flies. In mammals, the Sir2 ortholog Sirt1 promotes fat mobilization, fatty acid oxidation, glucose production, and insulin secretion...... hiện toàn bộ

AbstractThe global population of individuals over the age of 65 is growing at an unprecedented rate and is expected to reach 1.6 billion by 2050. Most older individuals are affected by multiple chronic diseases, leading to complex drug treatments and increased risk of physical and cognitive disability. Improving or preserving the health and quality of life of these...... hiện toàn bộ
Sirtuins at the crossroads of stemness, aging, and cancerAging Cell - Tập 16 Số 6 - Trang 1208-1218 - 2017
C. O'Callaghan, Athanassios Vassilopoulos
SummarySirtuins are stress‐responsive proteins that direct various post‐translational modifications (PTMs) and as a result, are considered to be master regulators of several cellular processes. They are known to both extend lifespan and regulate spontaneous tumor development. As both aging and cancer are...... hiện toàn bộ
Defective recruitment of motor proteins to autophagic compartments contributes to autophagic failure in agingAging Cell - Tập 17 Số 4 - 2018
Eloy Bejarano, John W. Murray, Xintao Wang, Olatz Pampliega, David Yin, Bindi Patel, Andrea Yuste, Allan W. Wolkoff, Ana María Cuervo
SummaryInability to preserve proteostasis with age contributes to the gradual loss of function that characterizes old organisms. Defective autophagy, a component of the proteostasis network for delivery and degradation of intracellular materials in lysosomes, has been described in multiple old organisms, while a robust autophagy response has been linked to longevit...... hiện toàn bộ
Oxidative stress and mitochondrial impairment can be separated from lipofuscin accumulation in aged human skeletal muscleAging Cell - Tập 6 Số 2 - Trang 245-256 - 2007

SummaryAccording to the free radical theory of aging, reactive oxygen species (ROS) act as a driving force of the aging process, and it is generally believed that mitochondrial dysfunction is a major source of increased oxidative stress in tissues with high content of mitochondria, such as muscle or brain. However, recent experiments in mouse models of premature ag...... hiện toàn bộ
Cardiolipin remodeling by ALCAT1 links mitochondrial dysfunction to Parkinson’s diseasesAging Cell - Tập 18 Số 3 - 2019

AbstractCardiolipin (CL) is a mitochondrial signature phospholipid that is required for membrane structure, respiration, dynamics, and mitophagy. Oxidative damage of CL by reactive oxygen species is implicated in the pathogenesis of Parkinson's disease (PD), but the underlying cause remains elusive. This work investigated the role of ALCAT1, an acyltransferase that...... hiện toàn bộ
