Effects of β-Nicotinamide Mononucleotide, Berberine, and Cordycepin on Lipid Droplet Content and Developmental Ability of Vitrified Bovine Oocytes

Antioxidants, 2023
Oocyte vitrification is crucial for livestock reproduction, germplasm conservation, and human-assisted reproduction, but the overabundance of lipids is highly detrimental to oocyte development.

Oxidative and Antioxidant Systems in Ferroptosis of Cancer: Mechanisms, Regulations, and Therapeutic Targeting

MedComm – Oncology, Volume 5, Issue 3, September 2026.
Ferroptosis is governed by the balance between reactive oxygen species (ROS)‐driven lipid peroxidation and a multi‐tiered antioxidant network. ROS sources include mitochondrial electron transport chain, voltage‐dependent anion channels, NADPH oxidases, and endoplasmic reticulum‐resident oxidoreductases, while antioxidant defenses span the primary GSH ...

Nicotinamide Mononucleotide (NMN) Improves the Senescence of Mouse Vascular Smooth Muscle Cells Induced by Ang II Through Activating p-AMPK/KLF4 Pathway

Pharmaceuticals
Background: Vascular smooth muscle cells (VSMCs) senescence exacerbates vascular diseases like atherosclerosis and hypertension. Angiotensin II (Ang II) is a strong inducer of VSMCs senescence, causing vascular damage, though its exact mechanism is ...

NAD+ Metabolic Reprogramming Drives CD8+ T Cells Senescence and Exacerbates Ulcerative Colitis

Aging Cell, Volume 25, Issue 9, September 2026.
Nicotinamide adenine dinucleotide (NAD+) depletion induces mitochondrial dysfunction and cytosolic mtDNA leakage in CD8+ T cells, activating the cGAS‐STING pathway and promoting a senescence‐associated secretory phenotype (SASP). The resulting pro‐inflammatory CD8+ T cells release IFN‐γ and TNF‐α, disrupt the intestinal epithelial barrier, and ...

Targeting m6A Modifications Regulating Ferroptosis Offers Novel Therapy in Diseases

Cell Proliferation, Volume 59, Issue 9, September 2026.
m6A RNA modification regulates ferroptosis by balancing iron metabolism, lipid peroxidation, and antioxidant defenses. Dysregulated m6A signaling disrupts pro‐ and anti‐ferroptotic factors, leading to excess ROS, Fe3+ accumulation, and lipid peroxidation–driven cell death. Targeting m6A‐mediated ferroptotic regulation represents a promising therapeutic

Integrative simulation analysis of myocardial ischaemia–reperfusion injury

The Journal of Physiology, Volume 604, Issue 18, Page 7640-7662, 15 September 2026.
Abstract figure legend A comprehensive mathematical model of ventricular myocyte was developed to gain insights into the mechanisms underlying cardiac ischaemia–reperfusion injury. The model integrates excitation–contraction (E–C) coupling, cytosolic and mitochondrial pH regulation, pH dependence of major E–C coupling components and cellular energy ...

SIRT6‐Mediated Deacetylation of ATF3 Promotes Silica‐Induced Lung Fibrosis by Enhancing its Nuclear Import via Binding to Importin α

Advanced Science, Volume 13, Issue 46, 17 August 2026.
SIRT6‐mediated ATF3 acetylation drives MGARP transcription and mitochondrial dysfunction in macrophages, promoting macrophage senescence and pulmonary fibrosis. Mechanistically, HSP70/Importin α competitively binds to ATF3, modulating its nuclear translocation.
