Resveratrol (RES), a natural polyphenolic compound, has garnered significant attention for its therapeutic potential in various pathological conditions. This review explores how RES modulates mitophagy-the selective autophagic degradation of mitochondria essential maintaining cellular homeostasis. promotes the initiation and execution mitophagy by enhancing PINK1/Parkin-mediated mitochondrial clearance, reducing reactive oxygen species production, mitigating apoptosis, thereby preserving integrity. Additionally, regulates through activation key molecular targets such as AMP-activated protein kinase (AMPK), mechanistic target rapamycin (mTOR), deacetylases (SIRT1 SIRT3), quality control (MQC) pathways, demonstrating substantial effects multiple disease models. We provide detailed account biosynthetic pharmacokinetics, metabolic characteristics RES, focusing on role modulation implications medical applications. Potential adverse associated with clinical use are also discussed. Despite promising properties, application is limited issues bioavailability pharmacokinetic profiles.

Mitochondria adapt to the cell proliferative demands induced by growth factors through dynamic changes in morphology, distribution, and metabolic activity. Galectin-8 (Gal-8), a carbohydrate-binding protein that promotes proliferation transactivating EGFR-ERK signaling pathway, is overexpressed several cancers. However, its impact on mitochondrial dynamics during remains unknown. Using MDCK RPTEC kidney epithelial cells, we demonstrate Gal-8 induces fragmentation perinuclear redistribution. Additionally, mitochondria adopt donut-shaped morphologies, live-cell imaging with two Keima-based reporters demonstrates Gal-8-induced mitophagy. ERK inhibition abrogates all these proliferation. Studies established mutant versions of CHO cells reveal response require interactions between N-terminal carbohydrate recognition domain α-2,3-sialylated N-glycans at surface. DRP1, key regulator fission, becomes phosphorylated or an ERK-dependent manner, mediating Bafilomycin A proliferation, suggesting mitophagy serves as adaptation demands. Functional analysis under stimulation shows maintain active electron transport chain, partially uncoupled from ATP synthesis, increased membrane potential, indicative healthy mitochondria. Meanwhile, exhibit extracellular acidification rate lactate production via aerobic glycolysis, hallmark state.
