- Forcing contacts between mitochondria and the endoplasmic reticulum extends lifespan in a Drosophila model of Alzheimer's disease
Summary: Enhancing mitochondria–ER contacts ameliorates locomotor phenotypes and extends lifespan in a fly model of Alzheimer's disease.
- Restriction of mitochondrial calcium overload by mcu inactivation renders a neuroprotective effect in zebrafish models of Parkinson's disease
Summary: Mitochondrial calcium overload causes mitochondrial dysfunction in Parkinson's disease. Inactivation of mitochondrial calcium uniporter reverses mitochondrial calcium overload and rescues dopaminergic neurons in our zebrafish models of Parkinson's disease.
- Minimal effects of spargel (PGC-1) overexpression in a Drosophila mitochondrial disease model
Summary: Overexpression of spargel, the fly PGC-1 homologue proposed as a mitochondrial biogenesis regulator, has minimal effects on the phenotype of tko25t, considered a fly model for mitochondrial disease.
- Detection of changes in mitochondrial hydrogen sulfide in vivo in the fish model Poecilia mexicana (Poeciliidae)
Summary: We established the mitochondria-targeted mass spectrometry probe MitoA for H2S detection in vivo in the animal model Poecilia mexicana for the first time.
- Gcn5 histone acetyltransferase is present in the mitoplasts
Summary: In yeast mitochondria the Gcn5 protein is present in the mitoplasts and is localized in the inner mitochondrial membrane. Its deletion affects the mitochondrial phenotype and is related to a marked decrease of mitochondrial DNA content.
- The effects of AICAR and rapamycin on mitochondrial function in immortalized mitochondrial DNA mutator murine embryonic fibroblasts
Summary: A novel mitochondrial DNA mutator murine embryonic fibroblast cell line was created and the effects of the anti-aging compounds rapamycin and AICAR on energy metabolism in these cells was determined.
- Characterisation of maturation of photoreceptor cell subtypes during zebrafish retinal development
Summary: We characterised subtype-specific growth of the different photoreceptor compartments, organelle distribution and the influence of light on the growth of the apical membrane.
- Mitochondrial dynamics and respiration within cells with increased open pore cytoskeletal meshes
Summary: We assessed the effect of cytoskeletal inhibitors and the use of a calcium ionophore as an additional stressor on mitochondrial motility and bioenergetic function in fibroblasts and fibrosarcoma cells.
- Molecular regulation of high muscle mass in developing Blonde d'Aquitaine cattle foetuses
Summary: We explored the molecular basis of high muscle mass in Blonde d’Aquitaine cattle, and found that mRNA encoding slow fibres and mitochondrial proteins were downregulated in this breed.
- Evidence that differentiation-inducing factor-1 controls chemotaxis and cell differentiation, at least in part, via mitochondria in D. discoideum
Summary: DIF-1 regulates Dictyostelium chemotaxis and differentiation. We synthesized DIF-1-BODIPY, a fluorescent DIF-1 derivative. DIF-1-BODIPY localized to mitochondria, suggesting that DIF-1 functions, at least in part, via mitochondria.
