Mitochondrial fission and apoptosis: An ongoing trial

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2006
Apoptosis is a form of programmed cell death that is essential for the development and tissue homeostasis in all metazoan animals. Mitochondria play a critical role during apoptosis, since the release of pro-apoptogenic proteins from the organelle is a pivotal event in cell death triggered by many cytotoxic stimuli.

Illuminating Mitochondrial RNA G‐Quadruplexes as Structural Brakes on RNA Granule Assembly and OXPHOS

open access: yesAdvanced Science, EarlyView.
A new fluorescent probe, MitoQUMA, brings mitochondrial RNA G‐quadruplexes (mtRNA G4s) into view in live cells. This tool reveals that excessive mtRNA G4 formation halts mitochondrial RNA granule (MRG) assembly, opposite to the phase‐separation role of cytoplasmic RNA G4s. A chemical genetic screen further identifies a Wnt/β‐catenin–GRSF1–mtRNA G4 axis

Actin filaments target the oligomeric maturation of the dynamin GTPase Drp1 to mitochondrial fission sites

open access: yeseLife, 2015
While the dynamin GTPase Drp1 plays a critical role during mitochondrial fission, mechanisms controlling its recruitment to fission sites are unclear. A current assumption is that cytosolic Drp1 is recruited directly to fission sites immediately prior to

Lactylation Reprogramming in the Bone Infection Microenvironment Identifies PGK1 K361 as a Potential Therapeutic Target for Osteogenic Dysfunction

open access: yesAdvanced Science, EarlyView.
Staphylococcus aureus (S. aureus) infection creates a high‐lactate microenvironment, promoting p300‐mediated lactylation of PGK1 at lysine 361 (K361). Lactylated PGK1 translocates to the mitochondrial outer membrane and interacts with VDAC3. This interaction triggers FtMt downregulation, iron accumulation, and excessive PINK1/Parkin‐mediated mitophagy,

DRP3 and ELM1 are required for mitochondrial fission in the liverwort Marchantia polymorpha

open access: yesScientific Reports, 2017
Mitochondria increase in number by the fission of existing mitochondria. Mitochondrial fission is needed to provide mitochondria to daughter cells during cell division.

Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

open access: yesAnnals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Myo‐Inositol Mitigates Oxidative Stress in Bovine Mammary Epithelial Cells via Activation of the SIRT5/Nrf2 Signaling Axis

open access: yesAnimal Research and One Health, EarlyView.
Myo‐inositol alleviates oxidative stress in dairy cow mammary epithelial cells via the Sirt5/Nrf2 pathway to promote mitochondrial fusion. This graphical abstract was created with BioRender.com. ABSTRACT High‐yielding dairy cows are susceptible to mammary gland oxidative stress due to prolonged intensive lactation, leading to redox imbalance.

The 3‐Hit Metabolic Signaling Model for Autism Spectrum Disorder: A Summary

open access: yesAutism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a highly heritable yet environmentally sensitive neurodevelopmental condition whose biological heterogeneity has resisted a unifying causal explanation for over 100 years. The 3‐hit metabolic signaling model proposes that ASD arises from abnormal persistence of an evolutionarily conserved stress‐response ...

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

open access: yesBMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

open access: yesBMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.
