The Hallmarks of Aging

TL;DR: Nine tentative hallmarks that represent common denominators of aging in different organisms are enumerated, with special emphasis on mammalian aging, to identify pharmaceutical targets to improve human health during aging, with minimal side effects.
Journal ArticleDOI

Mitochondrial Reactive Oxygen Species (ROS) and ROS-Induced ROS Release

TL;DR: The mechanism of mitochondrial RIRR highlights the central role of mitochondria-formed ROS, and all of the known ROS-producing sites and their relevance to the mitochondrial ROS production in vivo are discussed.
Journal ArticleDOI

The Warburg Effect: How Does it Benefit Cancer Cells?

TL;DR: Several proposed explanations for the function of Warburg Effect are analyzed, emphasize their rationale, and discuss their controversies.
Journal ArticleDOI

Modulation of oxidative stress as an anticancer strategy.

TL;DR: The controversial role of ROS in tumour development and in responses to anticancer therapies is addressed, and the idea that targeting the antioxidant capacity of tumour cells can have a positive therapeutic impact is elaborate.
Journal ArticleDOI

Cellular mechanisms and physiological consequences of redox-dependent signalling

TL;DR: The sources of ROS within cells and what is known regarding how intracellular oxidant levels are regulated are discussed, with the recent observations that reduction–oxidation (redox)-dependent regulation has a crucial role in an ever-widening range of biological activities.

Aging: A Theory Based on Free Radical and Radiation Chemistry

TL;DR: It seems possible that one factor in aging may be related to deleterious side attacks of free radicals (which are normally produced in the course of cellular metabolism) on cell constituents.
Journal ArticleDOI

How mitochondria produce reactive oxygen species.

TL;DR: The description outlined here facilitates the understanding of factors that favour mitochondrial ROS production and develops better methods to measure mitochondrial O2•− and H2O2 formation in vivo, as uncertainty about these values hampers studies on the role of mitochondrial ROS in pathological oxidative damage and redox signalling.

Induction of apoptotic program in cell-free extracts : requirement for datp and cytochrome c

TL;DR: Cells undergoing apoptosis in vivo showed increased release of cy tochrome c to their cytosol, suggesting that mitochondria may function in apoptosis by releasing cytochrome c.
Journal ArticleDOI

Regulation of cancer cell metabolism

TL;DR: Interest in the topic of tumour metabolism has waxed and waned over the past century, but it has become clear that many of the signalling pathways that are affected by genetic mutations and the tumour microenvironment have a profound effect on core metabolism, making this topic once again one of the most intense areas of research in cancer biology.

A role for mitochondria in NLRP3 inflammasome activation

TL;DR: It is shown that mitophagy/autophagy blockade leads to the accumulation of damaged, ROS-generating mitochondria, and this in turn activates the NLRP3 inflammasome, and may explain the frequent association of mitochondrial damage with inflammatory diseases.
