While mitochondria are key for energy dissipation in brown fat, it is unknown if they can drive adipocyte browning. Here, we show that the mitochondrial cristae biogenesis protein optic atrophy 1 (Opa1) facilitates cell-autonomous adipocyte browning. In two cohorts of patients with obesity, ...

Mitochondria are critical for metabolic homeostasis of the liver, and their dysfunction is a major cause of liver diseases. Optic atrophy 1 (OPA1) is a mitochondrial fusion protein with a role in cristae shaping. Disruption of OPA1 causes mitochondrial dysfunction. However, the role of OPA1 in...
To the best of our knowledge on the role of mitochondria in the modulation of neuroinflammation, we focused on the mitochondrial uncoupling protein-2 (UCP2), known to control mitochondrial functions and to be implicated in a variety of physiological and pathological processes. In primary microglial...
TOM22, a core compo- nent of the mitochondria outer membrane protein translocation pore, is a mitochondrial receptor for the proapoptotic protein Bax. Cell Death Differ. 14:785-794. doi:10.1038/sj.cdd.4402055Bellot G, Cartron PF, Er E, Oliver L, Juin P, Armstrong LC, Bornstein P, ...
14. Amino acids are assembled into proteins in the cells ___. a. in the nucleus b. on ribosomes c. in mitochondria d. in lysosomes e. in the Golgi complex 15. During protein synthesis a single mRNA molecular may be associated with several ribosomes to form ___. a. a gene b. lys...
Mitochondria are important regulators of macrophage polarisation. Here, we show that arginase-2 (Arg2) is a microRNA-155 (miR-155) and interleukin-10 (IL-10) regulated protein localized at the mitochondria in inflammatory macrophages, and is critical for IL-10-induced modulation of mitochondrial...
Mitochondria contain their own genome, known as mitochondrial DNA (mtDNA), which is circular, intron-free, double-stranded, haploid, and approximately 16.6 kb8. The mitochondrial DNA copy number (mtDNA-CN) refers to the number of mtDNA copies per cell and it can be conveniently determined from...
