Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,

Mitofusin 2 Promotes Apoptosis of CD4+ T Cells by Inhibiting Autophagy in Sepsis

open access: yesMediators of Inflammation, 2017
Apoptosis of CD4+ T cells is a primary pathophysiological mechanism of immune dysfunction in the pathogenesis of sepsis. Mitofusin 2 (Mfn2), an integral mitochondrial outer membrane protein, has been confirmed to be associated with cellular metabolism ...

Biallelic Nonsense Variants in NEFL May Cause a Non‐Length‐Dependent Neuropathy With Temporal Dispersion on Nerve Conduction Studies

open access: yesJournal of the Peripheral Nervous System, Volume 31, Issue 2, June 2026.
ABSTRACT Background and Aims Pathogenic variants in NEFL, the gene that encodes the light polypeptide subunit of neurofilaments, are an uncommon cause of autosomal recessive Charcot‐Marie‐Tooth (CMT) disease. In this study, we describe the clinical and electrophysiological features of two families with early‐onset CMT carrying nonsense variants in the ...

Molecular Probes for Tracking Reactive Oxygen Species at the Organelle Interface

open access: yesAnalysis &Sensing, Volume 6, Issue 3, May 2026.
This perspective charts the frontier of visualizing compartmentalized redox signaling across mitochondria, the ER, lysosomes, and the underexplored peroxisome. It discusses evolving molecular probe designs, the integration of multiplexed imaging, and the specific engineering challenges for tracking ROS at organelle interfaces.

Mfn2-dependent fusion pathway of PE-enriched micron-sized vesicles

open access: yesProceedings of the National Academy of Sciences
Mitofusins (Mfn1 and Mfn2) are the mitochondrial outer-membrane fusion proteins in mammals and belong to the dynamin superfamily of multidomain GTPases. Recent structural studies of truncated variants lacking alpha helical transmembrane domains suggested that Mfns dimerize to promote the approximation and the fusion of the mitochondrial outer membranes

Mitochondrial Homeostasis in Pancreatic β Cell Function: Mechanisms and Therapeutic Targets for Diabetes

open access: yesJournal of Diabetes, Volume 18, Issue 5, May 2026.
This review highlights mitochondrial dysfunction as a central driver of pancreatic β cell failure in diabetes, caused by disrupted mitochondrial quality control (MQC), oxidative stress, and impaired organelle communication. Emerging therapies, such as DRAK2 inhibitors and metabolic reprogramming agents, show promise in restoring β cell function by ...

From “Passive Supplementation” to “Active Repair”: Melatonin Reshapes the Treatment Paradigm for Late‐Onset Hypogonadism by Targeting Leydig Cell Senescence

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Melatonin restores testosterone production in aging Leydig cells by targeting key pathological drivers, particularly oxidative stress and mitochondrial dysfunction. This approach offers a fundamental strategy to reshape the Late‐onset hypogonadism treatment paradigm.

Upregulation of peroxisome proliferator-activated receptor gamma coactivator gene ( PGC1A ) during weight loss is related to insulin sensitivity but not to energy expenditure [PDF]

open access: yes, 2018
Aims/hypothesis: We investigated whether skeletal muscle peroxisome proliferator-activated receptor gamma coactivator-1 (PGC1A; also known as PPARGC1A) and its target mitofusin-2 (MFN2), as well as carnitine palmitoyltransferase-1 (CPT1; also known as ...

Preoperative Beta‐Hydroxy‐Beta‐Methyl‐Butyrate Supplementation Reduces Mitochondrial Dynamics Proteins and Preserves Hepatic Mitochondrial Function After Partial Hepatectomy in Mice

open access: yesActa Physiologica, Volume 242, Issue 5, May 2026.
ABSTRACT Aim The liver exhibits a remarkable regenerative capacity, enabling this organ to maintain homeostasis even after significant injury. However, hepatic regeneration requires sufficient energy to sustain cellular hypertrophy and proliferation, thus ensuring efficient tissue repair.
