Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Participation of mitochondrial fission during mitophagy [PDF]

open access: yesCell Cycle, 2013
Due to the key role of mitochondria in cell metabolism, the quantity and quality of this organelle must be maintained properly, which is achieved by constitutive mitochondrial fusion and fission as well as biogenesis and degradation. A fission complex controls mitochondrial division, whereas degradation occurs primarily through autophagy.

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

open access: yesFEBS 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 ...

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

open access: yesEcotoxicology 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.

Distinct molecular signatures of fission predict mitochondrial degradation or proliferation

open access: yes, 2021
Posté sur BioRxiv le 11 novembre 2020Mitochondrial fission is a highly regulated process which, when disrupted, can alter metabolism, proliferation and apoptosis 1–3 . The downstream effects have implications for many diseases, from neurodegeneration 4–6

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

open access: yesAging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Respiratory chain complexes in dynamic mitochondria display a patchy distribution in life cells

open access: yes, 2010
Background: Mitochondria, the main suppliers of cellular energy, are dynamic organelles that fuse and divide frequently. Constraining these processes impairs mitochondrial is closely linked to certain neurodegenerative diseases.

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

Mechanisms of hepatocellular toxicity associated with dronedarone and other mitochondrial toxicants [PDF]

open access: yes, 2014
Idiosyncratic drug-induced liver injury is a rare toxic event that typically occurs at therapeutic doses, which are generally safe to the majority of patients.
