TLDR
This Review discusses how mitochondria catabolize nutrients for energy, generate biosynthetic precursors for macromolecules, compartmentalize metabolites for the maintenance of redox homeostasis and function as hubs for metabolic waste management.
Abstract
Although classically appreciated for their role as the powerhouse of the cell, the metabolic functions of mitochondria reach far beyond bioenergetics. In this Review, we discuss how mitochondria catabolize nutrients for energy, generate biosynthetic precursors for macromolecules, compartmentalize metabolites for the maintenance of redox homeostasis and function as hubs for metabolic waste management. We address the importance of these roles in both normal physiology and in disease.

Pathophysiology of Type 2 Diabetes Mellitus.

TL;DR: This review analyzes the key aspects of type 2 Diabetes Mellitus, as well as the molecular mechanisms and pathways implicated in insulin metabolism leading to T2DM and insulin resistance, and summarizes the data gathered up until now.

Molecular mechanisms and physiological functions of mitophagy.

TL;DR: In this article, the authors review the current molecular understanding of mitophagy, and its physiological implications, and discuss how multiple mitophathy pathways coordinately modulate mitochondrial fitness and populations.

Tissue of origin dictates branched-chain amino acid metabolism in mutant Kras-driven cancers

TL;DR: Loss of Bcat1 and Bcat2, the enzymes responsible for BCAA use, impairs NSCLC tumor formation, but these enzymes are not required for PDAC tumorformation, arguing that tissue of origin is an important determinant of how cancers satisfy their metabolic requirements.

PINK1 and Parkin mitochondrial quality control: a source of regional vulnerability in Parkinson’s disease

TL;DR: This review focuses on understanding the unique challenges faced by the mitochondria in neurons vulnerable to neurodegeneration in Parkinson’s and summarizes evidence that mitochondrial dysfunction contributes to disease pathogenesis and to cell death in these subpopulations.

Understanding the Warburg Effect: The Metabolic Requirements of Cell Proliferation

TL;DR: It is proposed that the metabolism of cancer cells, and indeed all proliferating cells, is adapted to facilitate the uptake and incorporation of nutrients into the biomass needed to produce a new cell.

ROS Function in Redox Signaling and Oxidative Stress

TL;DR: It is argued that redox biology, rather than oxidative stress, underlies physiological and pathological conditions.

Mitochondria, Oxidants, and Aging

TL;DR: The evidence is reviewed that both supports and conflicts with the free radical theory of aging and the growing link between mitochondrial metabolism, oxidant formation, and the biology of aging is examined.

Beyond aerobic glycolysis : Transformed cells can engage in glutamine metabolism that exceeds the requirement for protein and nucleotide synthesis

TL;DR: Transformed cells exhibit a high rate of glutamine consumption that cannot be explained by the nitrogen demand imposed by nucleotide synthesis or maintenance of nonessential amino acid pools, and glutamine metabolism provides a carbon source that facilitates the cell's ability to use glucose-derived carbon and TCA cycle intermediates as biosynthetic precursors.

Physiological roles of mitochondrial reactive oxygen species.

TL;DR: More and more evidence suggests that mROS are critical for healthy cell function, and this evidence is discussed following some background on the generation and regulation ofmROS.
