WebOct 17, 2024 · This work investigated the effect of thyroxine on the biogenesis and quality control system of rat liver mitochondria. Chronic administration of thyroxine to experimental animals induced hyperthyroidism, which was confirmed by a severalfold increase in serum-free triiodothyronine and thyroxine concentrations. The uptake of oxygen was found to … WebDec 3, 2009 · Neurodegenerative diseases are a common late-life scourge for which diseasemodifying treatments are sorely needed. Mitochondrial perturbation is commonly observed in these diseases, so pursuing treatment development strategies that target mitochondria or processes affected by mitochondria seems reasonable.

WebDepending on the organism, mitochondria consist approximately of 500-1,400 different proteins. By far most of these proteins are encoded by nuclear genes and synthesized on cytosolic ribosomes. Targeting signals direct these proteins into mitochondria and there to their respective subcompartment: the outer membrane, the intermembrane space (IMS ... WebThese changes occur in your cells, particularly your mitochondria—tiny power generators that are responsible for churning out 90% of your body’s energy. But mitochondrial biogenesis is the specific mechanism that your body uses to respond to these adaptive changes in your environment. As you become more fit as a marathon runner, adding …
WebNov 15, 2004 · We have recently shown that long-term exposure of cells in culture to low concentrations of NO induces mitochondrial biogenesis.This process is mediated by cGMP, resulting from NO-dependent activation of “soluble” guanylate cyclase (sGC), and involves increased expression of peroxisome proliferator-activated receptor γ coactivator … WebApr 30, 2007 · This chapter contains sections titled: The Mitochondrial Genome.
