Translocation arrest by reversible folding of a precursor protein imported into mitochondria [PDF]
, 1989 Passage of precursor proteins through translocation contact sites of mitochondria was investigated by studying the import of a fusion protein consisting of the NH2-terminal 167 amino acids of yeast cytochrome b2 precursor and the complete mouse ...

Emergence of the mitochondrial reticulum from fission and fusion dynamics
, 2012 Mitochondria form a dynamic tubular reticulum within eukaryotic cells. Currently, quantitative understanding of its morphological characteristics is largely absent, despite major progress in deciphering the molecular fission and fusion machineries ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer
Molecular Oncology, EarlyView.Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization
Molecular Oncology, EarlyView.In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Cyclic AMP Receptor Protein from Yeast Mitochondria [PDF]
, 1985 We have identified and characterized a cyclic AMP receptor protein in mitochondria of the yeast Saccharomyces cerevisiae. The binding is specific for cyclic nucleotides, particularly for cyclic AMP which is bound with high affinity (Kd of 10(-9) M) at 1 ...

Mitochondrial membrane potential and aging
Aging Cell, 2003 SummaryThe mitochondrial membrane potential (or protonmotive force) is the central bioenergetic parameter that controls respiratory rate, ATP synthesis and the generation of reactive oxygen species, and is itself controlled by electron transport and proton leaks.

FEBS Open Bio, EarlyView.We first identified functional murine mitochondrial N‐formyl peptides (MT‐FPs) and investigated their effects on the in vitro myeloid‐derived suppressor cell (MDSC) generation from bone marrow cells. We demonstrated that MT‐FPs acted directly on bone marrow cells to promote MDSC generation and modulated the polymorphonuclear (PMN)‐MDSC/monocyte (M ...

A mitofusin-dependent docking ring complex triggers mitochondrial fusion in vitro
eLife, 2016 Fusion of mitochondrial outer membranes is crucial for proper organelle function and involves large GTPases called mitofusins. The discrete steps that allow mitochondria to attach to one another and merge their outer membranes are unknown.

Imaging mitochondrial membrane potentials
Biophysical Journal, 1993 process remain to be elucidated. The elusiveness of this goal can be attributed, at least in part, to the absence of structural information about the mitochondrion itself at several levels of complexity. It is obvious, for example, that obtaining atomic structures of the respiratory chain protein complexes by x-ray or electron crystallography would ...
