Programmed Cell Senescence during Mammalian Embryonic Development

TLDR
It is shown that senescence occurs during mammalian embryonic development at multiple locations, including the mesonephros and the endolymphatic sac of the inner ear, and it is proposed that this is the evolutionary origin of damage-inducedsenescence.

Molecular mechanisms of cell death: recommendations of the Nomenclature Committee on Cell Death 2018.

Lorenzo Galluzzi, +186 more
TL;DR: The Nomenclature Committee on Cell Death (NCCD) has formulated guidelines for the definition and interpretation of cell death from morphological, biochemical, and functional perspectives.

Naturally occurring p16 Ink4a -positive cells shorten healthy lifespan

TL;DR: It is shown that compared to vehicle alone, AP20187 treatment extended median lifespan in both male and female mice of two distinct genetic backgrounds and the clearance of p16Ink4a-positive cells delayed tumorigenesis and attenuated age-related deterioration of several organs without apparent side effects.

Cellular senescence: from physiology to pathology.

TL;DR: In cancer and during active tissue repair, pro-senescent therapies contribute to minimize the damage by limiting proliferation and fibrosis, respectively, and antisenescent therapies may help to eliminate accumulated senescent cells and to recover tissue function.
Journal ArticleDOI

The role of senescent cells in ageing

TL;DR: A deeper understanding of the molecular mechanisms underlying the multi-step progression of senescence and the development and function of acute versus chronic senescent cells may lead to new therapeutic strategies for age-related pathologies and extend healthy lifespan.

A biomarker that identifies senescent human cells in culture and in aging skin in vivo

TL;DR: It is shown that several human cells express a beta-galactosidase, histochemically detectable at pH 6, upon senescence in culture, which provides in situ evidence that senescent cells may exist and accumulate with age in vivo.

Cellular senescence: when bad things happen to good cells

TL;DR: Understanding the causes and consequences of cellular senescence has provided novel insights into how cells react to stress, especially genotoxic stress, and how this cellular response can affect complex organismal processes such as the development of cancer and ageing.

mTOR: from growth signal integration to cancer, diabetes and ageing

TL;DR: Mammalian TOR complex 1 (mTORC1) and mTORC2 exert their actions by regulating other important kinases, such as S6 kinase (S6K) and Akt.

Blinded by the Light: The Growing Complexity of p53

TL;DR: Control of p53's transcriptional activity is crucial for determining which p53 response is activated, a decision that must be understood if the next generation of drugs that selectively activate or inhibit p53 are to be exploited efficiently.
