TLDR
These transcriptional paradigms provide a basic framework for understanding the integration of mitochondrial biogenesis and function with signaling events that dictate cell- and tissue-specific energetic properties.Abstract:
Mitochondria contain their own genetic system and undergo a unique mode of cytoplasmic inheritance. Each organelle has multiple copies of a covalently closed circular DNA genome (mtDNA). The entire...read more

Role of nrf2 in oxidative stress and toxicity.
TL;DR: The nuclear factor erythroid 2-related factor 2 (Nrf2) is an emerging regulator of cellular resistance to oxidants that controls the basal and induced expression of an array of antioxidant response element-dependent genes to regulate the physiological and pathophysiological outcomes of oxidant exposure.
Journal ArticleDOI
MYC on the Path to Cancer
TL;DR: The richness of the understanding of MYC is reviewed, highlighting new biological insights and opportunities for cancer therapies.
Journal ArticleDOI
Fiber types in mammalian skeletal muscles.
TL;DR: Mammalian skeletal muscle comprises different fiber types, whose identity is first established during embryonic development by intrinsic myogenic control mechanisms and is later modulated by neural and hormonal factors.
Journal ArticleDOI
Metabolic control of mitochondrial biogenesis through the PGC-1 family regulatory network.
TL;DR: The results point to a central role for the PGC-1 family in integrating mitochondrial biogenesis and energy production with many diverse cellular functions.
Journal ArticleDOI
MYC, Metabolism, and Cancer
TL;DR: Because of the reliance of MYC-driven cancers on specific metabolic pathways, synthetic lethal interactions between MYC overexpression and specific enzyme inhibitors provide novel cancer therapeutic opportunities.

Hirschhorn,David Altshuler,Leif Groop +24 more
TL;DR: An analytical strategy is introduced, Gene Set Enrichment Analysis, designed to detect modest but coordinate changes in the expression of groups of functionally related genes, which identifies a set of genes involved in oxidative phosphorylation whose expression is coordinately decreased in human diabetic muscle.

Brown Adipose Tissue: Function and Physiological Significance
Barbara Cannon,Jan Nedergaard +1 more
TL;DR: The development of brown adipose tissue with its characteristic protein, uncoupling protein-1 (UCP1), was probably determinative for the evolutionary success of mammals, as its thermogenesis enhances neonatal survival and allows for active life even in cold surroundings.

Mechanisms Controlling Mitochondrial Biogenesis and Respiration through the Thermogenic Coactivator PGC-1
Zhidan Wu,Pere Puigserver,Ulf Andersson,Chen-Yu Zhang,Guillaume Adelmant,Vamsi K. Mootha,Amy E Troy,Saverio Cinti,Bradford B. Lowell,Richard C. Scarpulla,Bruce M. Spiegelman +10 more
TL;DR: PGC-1, a cold-inducible coactivator of nuclear receptors, stimulates mitochondrial biogenesis and respiration in muscle cells through an induction of uncoupling protein 2 (UCP-2) and through regulation of the nuclear respiratory factors (NRFs).

A cold-inducible coactivator of nuclear receptors linked to adaptive thermogenesis.
Pere Puigserver,Zhidan Wu,Cheol Won Park,Reed A. Graves,Margaret E. Wright,Bruce M. Spiegelman +5 more
TL;DR: Results indicate that PGC-1 plays a key role in linking nuclear receptors to the transcriptional program of adaptive thermogenesis.

A Mitochondrial Paradigm of Metabolic and Degenerative Diseases, Aging, and Cancer: A Dawn for Evolutionary Medicine
TL;DR: The mitochondria provide a direct link between the authors' environment and their genes and the mtDNA variants that permitted their forbears to energetically adapt to their ancestral homes are influencing their health today.
