Project description:Mitochondria are known to be functional organelles, but their role as a signaling unit is increasingly being appreciated. The recent identification of a short open reading frame (sORF) in the mitochondrial DNA (mtDNA) that encodes a signaling peptide, humanin, suggests the possible existence of additional sORFs in the mtDNA that yield bioactive peptides. Here we report the identification of a sORF within the mitochondrial 12S rRNA encoding a 16-amino-acid peptide named MOTS-c (mitochondrial open-reading-frame of the twelve S rRNA -c) that regulates insulin sensitivity and metabolic homeostasis. MOTS-c is detected in various tissues and in circulation in an age-dependent manner. Its primary target organ appears to be the skeletal muscle and its cellular actions inhibit the folate cycle and its tethered de novo purine biosynthesis, causing a significant accumulation of AICAR levels concomitantly with AMPK activation. MOTS-c treatment in mice prevented age-dependent and high-fat diet-induced insulin resistance, as well as diet-induced obesity. These results suggest that mitochondria may be more actively engaged in regulating metabolic homeostasis than previously recognized, through the production of peptides encoded within its genome that act at the cellular and organismal level. Human embryonic kidney cells (HEK293 cell line) were cultured in 10-cm dishes in 7 mL of phenol-free DMEM supplemented with 10% FBS and incubated with water (controls) or the 16-amino-acid peptide mitochondrial open-reading-frame of the twelve S rRNA-c (MOTS-c, 10 uM) for 4 or 72 hours prior to RNA extraction.

Project description:To understand the effect of MOTS-c treatment on cast immobilization-induced skeletal muscle atrophy, we injected MOTS-c into casted mice. We then performed gene expression profiling analysis using data obtained from RNA-seq of three groups: non-immobilization group, immobilization control group, and immobilization and MOTS-c treated group.

Project description:Mitochondria are principal metabolic organelles that are increasingly unveiled as immune regulators. However, it is currently not known whether mitochondrial-encoded peptides modulate T cells to induce changes in phenotype and function. Here, we found that MOTS-c prevented autoimmune β-cell destruction via phenotypical and functional changes of T cells in NOD mice, a type 1 diabetes (T1D) animal model. MOTS-c ameliorated the development of hyperglycemia and reduced islet-infiltrating immune cells. Furthermore, adoptive transfer of T cells from MOTS-c-treated NOD mice significantly decreased the incidence of diabetes in NOD-SCID mice. Metabolic and genomic analysis revealed that MOTS-c modulated T cell phenotype and function by regulating TCR/mTORC1 pathway. We observed that T1D patients had a lower serum MOTS-c level than healthy controls. Furthermore, MOTS-c reduced T cell activation by alleviating T cells from the glycolytic stress in T1D patients suggesting a potential therapeutic implication. Our findings indicate that the MOTS-c acts as a regulator of T cell phenotype and function in autoimmune diabetes.
