Protein folding causes an arrest of preprotein translocation into mitochondria in vivo [PDF]

, 1991
With vital yeast cells, a hybrid protein consisting of the amino- terminal third of the precursor to cytochrome b2 and of the entire dihydrofolate reductase was arrested on the import pathway into mitochondria.

Mitochondrial division, fusion and degradation

The Journal of Biochemistry, 2019
Abstract The mitochondrion is an essential organelle for a wide range of cellular processes, including energy production, metabolism, signal transduction and cell death. To execute these functions, mitochondria regulate their size, number, morphology and distribution in cells via mitochondrial division and fusion.

Mechanisms of Mitochondrial Fission and Fusion [PDF]

Cold Spring Harbor Perspectives in Biology, 2013
Mitochondria continually change shape through the combined actions of fission, fusion, and movement along cytoskeletal tracks. The lengths of mitochondria and the degree to which they form closed networks are determined by the balance between fission and fusion rates. These rates are influenced by metabolic and pathogenic conditions inside mitochondria

Dichloroacetate Stabilizes Mitochondrial Fusion Dynamics in Models of Neurodegeneration

Frontiers in Molecular Neuroscience, 2019
Mitochondrial dysfunction is a recognized hallmark of neurodegenerative diseases and abnormal mitochondrial fusion-fission dynamics have been implicated in the pathogenesis of neurodegenerative disorders. This study characterizes the effects of metabolic

Mitochondrial Fusion Machinery Specifically Involved in Energy Deprivation-Induced Autophagy

Frontiers in Cell and Developmental Biology, 2020
Mitochondria are highly dynamic organelles, which can form a network in cells through fusion, fission, and tubulation. Its morphology is closely related to the function of mitochondria. The damaged mitochondria can be removed by mitophagy.

Roles of mitochondrial fusion and fission in breast cancer progression: a systematic review

World Journal of Surgical Oncology, 2022
Background Mitochondria play critical roles in cellular physiological activity as cellular organelles. Under extracellular stimulation, mitochondria undergo constant fusion and fission to meet different cellular demands. Mitochondrial dynamics, which are

Triphenyl phosphate induced apoptosis of mice testicular Leydig cells and TM3 cells through ROS-mediated mitochondrial fusion inhibition

Ecotoxicology and Environmental Safety, 2023
Triphenyl phosphate (TPHP) is a widely used organophosphate flame retardant and has biological toxicity. Previous studies showed TPHP can restrain testosterone biosynthesis in Leydig cells, while the underlying mechanisms remain unclear.

Antifolding activity of hsp60 couples protein import into the mitochondrial matrix with export to the intermembrane space [PDF]

, 1992
Cytochrome b2 reaches the intermembrane space of mitochondria by transport into the matrix followed by export across the inner membrane. While in the matrix, the protein interacts with hsp60, which arrests its folding prior to export.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
