Apoptosis and Aging: Role of p66 Shc Redox Protein

Migliaccio, Enrica, Giorgio, Marco, Pelicci, Pier Giuseppe·2006·Antioxidants & Redox Signaling

Abstract

p66Shc was the first mammalian gene whose mutation was demonstrated to increase resistance to oxidative stress and to prolong life span. Many hypotheses have been formulated to explain the biochemical and molecular basis of mammalian aging. Among them the free radical theory of aging, which was first proposed half a century ago by Harman, has received much attention by biomedical scientists. This theory proposed that, because of their high reactivity, reactive oxygen species (ROS) would lead to unavoidable and potentially deleterious by-products, and such an increasingly damaging process could be responsible for degenerative diseases and aging. Recent reports suggest an important role of p66Shc protein in the regulation of cellular responses to oxidative stress, apoptosis, and aging. In this review we discuss what has been discovered about p66Shc in the past 10 years and we focus particularly on its role in ROS regulation, which appears to be extremely promising to define mammalian aging processes.

  • p66SHC sustains intracellular ROS and regulates redox signaling, mitochondrial apoptosis, and aging.

    “P66SHC protein is the largest isoform encoded by the ShcA locus, typical of vertebrates, and it sustains intracellular levels of ROS (Giorgio et al., 2005 Gertz & Steegborn, 2010) and regulates redox signaling pathways (Frijhoff et al., 2014), mitochondrial apoptosis (Migliaccio et al., 2006), and aging (Trinei et al., 2009).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
