Aging-dependent functional alterations of mitochondrial DNA (mtDNA) from human fibroblasts transferred into mtDNA-less cells [PDF]

, 1996
To investigate the role that aging-dependent accumulation of mitochondrial DNA (mtDNA) mutations plays in the senescence processes, mitochondria from fibroblasts of 21 normal human individuals between 20 weeks (fetal) and 103 years of age were introduced

Implementation of Drug‐Induced Rhabdomyolysis and Acute Kidney Injury in Microphysiological System

Advanced Functional Materials, EarlyView.
A modular Muscle–Kidney proximal tubule‐on‐a‐chip integrates 3D skeletal muscle and renal proximal tubule tissues to model drug‐induced rhabdomyolysis and acute kidney injury. The coculture system enables dynamic tissue interaction, functional contraction monitoring, and quantification of nephrotoxicity, revealing drug side effect‐induced metabolic ...

Mitochondrial dynamics and colorectal cancer biology: mechanisms and potential targets

Cell Communication and Signaling
Colorectal cancer (CRC) is a significant public health concern, and its development is associated with mitochondrial dysfunction. Mitochondria can adapt to the high metabolic demands of cancer cells owing to their plasticity and dynamic nature.

Modulation of mitochondrial dynamics in skeletal muscle during endurance training: early activation of fission and late induction of fusion protein expression

Journal of Physical Fitness and Sports Medicine
The mitochondria are highly plastic organelles. Exercise training alters mitochondrial dynamics (mitochondrial fission and fusion) in skeletal muscles and improves overall mitochondrial function by altering mitochondrial morphology and forming new ...

Structure and function of bacterial dynamin-like proteins [PDF]

, 2012
Membrane dynamics are essential for numerous cellular processes in eukaryotic and prokaryotic cells. In eukaryotic cells, membrane fusion and fission are often catalyzed by large GTPases of the dynamin protein family. These proteins couple GTP hydrolysis

Mitochondrial Fusion and Division

The FASEB Journal, 2012
Mitochondria play important roles in cellular functions including energy production, metabolism and cell death. Mitochondria are highly dynamic organelles that continuously fuse and divide in a regulated manner. A balance of fusion and division controls mitochondrial morphology and functions.

Mitochondrial Fusion and Fission in Mammals [PDF]

Annual Review of Cell and Developmental Biology, 2006
Eukaryotic cells maintain the overall shape of their mitochondria by balancing the opposing processes of mitochondrial fusion and fission. Unbalanced fission leads to mitochondrial fragmentation, and unbalanced fusion leads to mitochondrial elongation.

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation

Advanced Functional Materials, EarlyView.
Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

Modulation of Mitochondrial Dynamics in Primary Hippocampal Cultures of 5xFAD Mice by Mdivi-1, MFP, and Exogenous Zinc

Frontiers in Bioscience-Landmark
Background: Mitochondrial dynamics—the balance between fission, fusion, and mitophagy—are essential for maintaining cellular homeostasis and are increasingly implicated in the pathogenesis of Alzheimer’s disease (AD).

Wounding triggers MIRO-1 dependent mitochondrial fragmentation that accelerates epidermal wound closure through oxidative signaling. [PDF]

, 2020
Organisms respond to tissue damage through the upregulation of protective responses which restore tissue structure and metabolic function. Mitochondria are key sources of intracellular oxidative metabolic signals that maintain cellular homeostasis.
