Sumo1 Conjugates Mitochondrial Substrates and Participates in Mitochondrial Fission [PDF]

Current Biology, 2004
Mitochondrial fission requires the evolutionarily conserved dynamin related protein (DRP1), which is recruited from the cytosol to the mitochondrial outer membrane to coordinate membrane scission. Currently, the mechanism of recruitment and assembly of DRP1 on the mitochondria is unclear.

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.

GDAP1 mutations differ in their effects on mitochondrial dynamics and apoptosis depending on the mode of inheritance

Neurobiology of Disease, 2009
Mutations in the GDAP1 gene lead to recessively or dominantly inherited peripheral neuropathies (Charcot–Marie–Tooth disease; CMT). Here, we demonstrate that GDAP1 is a mitochondrial fission factor whose activity is dependent on the fission factors Drp1 ...

Melatonin improves mitochondrial function by preventing mitochondrial fission in cadmium-induced rat proximal tubular cell injury via SIRT1–PGC-1α pathway activation

Ecotoxicology and Environmental Safety, 2022
Melatonin is an indoleamine produced in the pineal gland and has many physiological roles. There is increasing evidence that melatonin ameliorates cadmium (Cd)-induced nephrotoxicity.

Intraspecific diversity of fission yeast mitochondrial genomes [PDF]

Genome Biology and Evolution, 2019
ABSTRACTThe fission yeastSchizosaccharomyces pombeis an important model organism, but its natural diversity and evolutionary history remain under-studied. In particular, the population genomics of theS. pombemitochondrial genome (mitogenome) has not been thoroughly investigated.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Mitochondrial Fission: Rings around the Organelle [PDF]

Current Biology, 2013
Mitochondria form a dynamic network in which organelles fuse or divide in response to metabolic changes or cellular stress. New work shows that mitochondria do not divide in isolation from other cellular structures. Rather, they carry out this process in partnership with the endoplasmic reticulum and actin filaments.

Mitochondrial Fission: Regulation and ER Connection

Molecules and Cells, 2014
Fission and fusion of mitochondrial tubules are the main processes determining mitochondrial shape and size in cells. As more evidence is found for the involvement of mitochondrial morphology in human pathology, it is important to elucidate the mechanisms of mitochondrial fission and fusion.

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...
