The Mitochondrial Calcium Uniporter controls skeletal muscle mass in vivo

(Submitter supplied) Muscle atrophy contributes to the poor prognosis of many physiopathological conditions, but pharmacological therapies are still limited. Muscle activity leads to major swings in mitochondrial [Ca2+] which control aerobic metabolism, cell death and survival pathways. We have investigated in vivo the effects of mitochondrial Ca2+ homeostasis in skeletal muscle function and trophism, by overexpressing or silencing the Mitochondrial Calcium Uniporter (MCU). more...

PGC-1 alpha isoforms and muscle hypertrophy

(Submitter supplied) An alternative promoter of the PGC-1alpha gene gives rise to three new PGC-1alpha isoforms refered to as PGC-1a2 (A2), PGC-1a3 (A3) and PGC-1a4 (A4). The proximal PGC-1 alpha promotor transcribes the canonical PGC-1 alpha which is refered to as PGC-1a1 (A1).G1/G2/G3 samples refer to the Green fluorescent protein (GFP) control samples used in this experiment. Forced expression of the PGC-1a4 isoform results in muslce hypertrophy associated with increased IGF-1 signaling and repression of myostatin signaling.

mRNA Expression Changes Induced by Myocardial MCU Inhibition

(Submitter supplied) Mitochondrial calcium is an important second-messenger controlling fight-or-flight responses in the heart. The molecular identity of MCU (Mitochondrial Calcium Uniporter) was recently discovered allowing us to test this hypothesis in vivo by expressiing a myocardial delimited dominant negative form of MCU. We queried mRNA expression changes induced by dominant negative MCU expression in the heart.

A PGC-1alpha-dependent decrease in mitochondrial oxidative metabolism in muscle of humans with inherited insulin resistance

(Submitter supplied) We used microarrays to assess gene expression profiling of 6 patients with a mutation (Arg1174Gln) in the tyrosine kinase domain of the insulin receptor gene (INSR) and 10 matched healthy controls

Skeletal muscle of patients with inherited insulin resistance

Analysis of muscle from patients with a mutation (Arg1174Gln) in the tyrosine kinase domain of the insulin receptor gene (INSR). This mutation is associated with inherited insulin resistance. Results provide insight into molecular mechanisms underlying insulin resistance in skeletal muscle.
