A SIRT7-Dependent Acetylation Switch of GABPβ1 Controls Mitochondrial Function

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Dongryeol Ryu, Hongbo Zhang, Matthias Alexander Sokrates Stein, Giuseppe Lo Sasso

Mitochondrial activity is controlled by proteins encoded by both nuclear and mitochondrial DNA. Here, we identify Sirt7 as a crucial regulator of mitochondrial homeostasis. Sirt7 deficiency in mice induces multisystemic mitochondrial dysfunction, which is ...

Investigation of genetic diversity of domestic C. hircus breeds reared within an early goat domestication area in Iran

Stéphane Joost

Iran is an area of particular interest for investigating goat diversity. Archaeological remains indicate early goat domestication (about 10 000 years ago) in the Iranian Zagros Mountains as well as in the high Euphrates valley and southeastern Anatolia. In ...

Live-Cell dSTORM of Cellular DNA Based on Direct DNA Labeling

Suliana Manley, Aleksandr Benke

We have implemented the super-resolution method of direct stochastic optical reconstruction microscopy (dSTORM) to image nuclear and mitochondrial DNA in living cells. We also demonstrate time-lapse imaging, all using a dye that associates directly with ce ...

Genetic Diversity of Sheep Breeds from Albania, Greece, and Italy Assessed by Mitochondrial DNA and Nuclear Polymorphisms (SNPs)

Stéphane Joost

We employed mtDNA and nuclear SNPs to investigate the genetic diversity of sheep breeds of three countries of the Mediterranean basin: Albania, Greece, and Italy. In total, 154 unique mtDNA haplotypes were detected by means of D-loop sequence analysis. The ...

Interdependence of AMPK and SIRT1 for Metabolic Adaptation to Fasting and Exercise in Skeletal Muscle

Johan Auwerx, Carlos Canto Alvarez, Chikage Mataki

During fasting and after exercise, skeletal muscle efficiently switches from carbohydrate to lipid as the main energy source to preserve glycogen stores and blood glucose levels for glucose-dependent tissues. Skeletal muscle cells sense this limitation in ...

Identification of RNA-binding surfaces in iron regulatory protein-1

Lukas Kühn

Post-transcriptional regulation of mRNA translation and stability in iron metabolism involves the interaction between the trans-acting cytoplasmic iron regulatory proteins (IRP-1 and IRP-2) and cis-acting iron-responsive elements (IREs) in mRNA 5'- or 3'-u ...

Maternal modulation of the inheritable meiosis I error Dipl I in mouse oocytes is associated with the type of mitochondrial DNA

Friedrich Beermann

The ovulation of diploid oocytes, abnormally arrested at or during the first meiotic division, is an inheritable trait (DiplI) in mice and modulated by a maternally transmitted factor. By repeated backcrossing, mouse strains with identical nuclear encoded ...
