Mechanical force induces mitochondrial fission
eLife, 2017 Eukaryotic cells are densely packed with macromolecular complexes and intertwining organelles, continually transported and reshaped. Intriguingly, organelles avoid clashing and entangling with each other in such limited space. Mitochondria form extensive

Cell Death DiscoveryAbstract Mitochondrial fission is a critical physiological process in eukaryotic cells, participating in various vital activities such as mitosis, mitochondria quality control, and mitophagy. Recent studies have revealed a tight connection between mitochondrial fission and the mitochondrial metabolism, as well as apoptosis, which involves ...

Mitochondrial Dynamics in the Metabolic Memory of Diabetic Retinopathy
Journal of Diabetes Research, 2022 Mitochondria play a central role in the development of diabetic retinopathy and in the metabolic memory associated with its continued progression. Mitochondria have a regulated fusion fission process, which is essential for their homeostasis.

Heat stress disrupts mitochondrial dynamics and ATF5 expression during porcine oocyte maturation
Journal of Animal Reproduction and BiotechnologyBackground: In mammals, DRP1 is a key regulator of mitochondrial fission during mitochondrial dynamics, whereas ATF5 promotes the mitochondrial unfolded protein response (UPRmt).

Regulation of Mitochondrial Dynamics and Neurodegenerative Diseases [PDF]
, 2011 Mitochondria are important cellular organelles in most metabolic processes and have a highly dynamic nature, undergoing frequent fission and fusion. The dynamic balance between fission and fusion plays critical roles in mitochondrial functions. In recent

Cell Death & Disease, 2018 AbstractDynamin-related protein 1 (DRP1) is a key molecule to regulate mitochondrial fission. DRP1 activity is modulated by phosphorylation and S-nitrosylation on serine and cysteine residues, respectively. However, it is still unexplored whether S-nitrosylation of DRP1 affects its phosphorylation.

Mitochondrial Dynamics: ER Actin Tightens the Drp1 Noose [PDF]
Current Biology, 2016 Drp1 is an oligomeric GTPase essential for mitochondrial division. A recent study has proposed a new model whereby machinery localized to the endoplasmic reticulum drives polymerization of actin, which then acts as a platform for Drp1 oligomerization and hydrolysis at mitochondrial constriction sites.

The mycotoxin phomoxanthone A disturbs the form and function of the inner mitochondrial membrane. [PDF]
, 2018 Mitochondria are cellular organelles with crucial functions in the generation and distribution of ATP, the buffering of cytosolic Ca2+ and the initiation of apoptosis. Compounds that interfere with these functions are termed mitochondrial toxins, many of

SIRT4 positively regulates autophagy via ULK1, but independently of HDAC6 and OPA1
FEBS Open Bio, EarlyView.Cells expressing SIRT4 (H161Y), a catalytically inactive mutant of the sirtuin SIRT4, fail to upregulate LC3B‐II and exhibit a reduced autophagic flux under stress conditions. Interestingly, SIRT4(H161Y) promotes phosphorylation of ULK1 at S638 and S758 that are associated with inhibition of autophagy initiation.
