Oxidative stress and exceptional human longevity: Systematic review.
Oxidative stress (OS) has been previously linked to the aging process, as have some diseases and geriatric syndromes as frailty and sarcopenia. The aim of the present study was to perform a systematic review on oxidative stress activity and extreme longevity in humans.We conducted a systematic literature review following the PRISMA guidelines. Observational studies assessing OS-biomarkers and/or antioxidants in long-lived individuals (97 years old or over) comparing them to those of one or more age groups, (at least one of which from comprising elderly subjects) were considered for inclusion. A narrative synthesis was planned. Quality of selected studies was assessed using the Newcastle-Ott…
El estrés oxidativo como predictor de longevidad; estudio de casos y controles
Resumen Introduccion La longevidad humana es un fenomeno complejo en el que influyen factores geneticos y ambientales. El estres oxidativo (EO) puede jugar un papel importante en este proceso. El envejecimiento exitoso podria relacionarse con la habilidad del organismo para hacer frente al EO. Nuestro objetivo es comparar los niveles en plasma de malondialdehido (MDA) y proteinas oxidadas (PO) entre sujetos mayores de 97 anos y con edad entre 70 y 80 anos, para comprender mejor los efectos del estres oxidativo en la longevidad humana. Material y metodos Estudio de casos y controles de base poblacional. Se consideraron casos todas aquellas personas nacidas y residentes en la comarca de la Ri…
Centenarians, but not octogenarians, up-regulate the expression of microRNAs
Centenarians exhibit extreme longevity and a remarkable compression of morbidity. They have a unique capacity to maintain homeostatic mechanisms. Since small non-coding RNAs (including microRNAs) are implicated in the regulation of gene expression, we hypothesised that longevity of centenarians may reflect alterations in small non-coding RNA expression. We report the first comparison of microRNAs expression profiles in mononuclear cells from centenarians, octogenarians and young individuals resident near Valencia, Spain. Principal Component Analysis of the expression of 15,644 mature microRNAs and, 2,334 snoRNAs and scaRNAs in centenarians revealed a significant overlap with profiles in you…
