Summary: Salinized land is spreading globally, threatening crop yields and the ability to feed a growing population. This review discusses the mechanisms of nano-enabled antioxidant enzyme-mediated plant tolerance to salt stress, including maintaining ROS homeostasis, enhancing ion retention and elimination, increasing nitric oxide production, signaling pathways, and reducing oxidative damage. Common techniques like protecting cells from oxidative stress and maintaining ionic balance are highlighted. The application and potential mechanisms of nanotechnology in salt tolerance of plants are also explored. The review aims to aid researchers in various fields to comprehend the potential of novel solutions for sustainable agriculture addressing salinity issues.

Summary: Mild inhibition of mitochondrial function can extend lifespan, which has been demonstrated in yeast, worms, and drosophila through genetic disruption of mitochondrial respiratory components. Chrysin and apigenin have been identified as compounds that can reduce ATP production, increase the lifespan of worms, and induce transient inhibition of mitochondrial respiration and early ROS formation. Furthermore, the lifespan-extending effect of these compounds is dependent on the transient ROS formation and the activation of certain genes. These findings shed light on the potential of pharmacologically inhibiting mitochondrial function and the role of plant-derived polyphenols in delaying aging.

Summary: Many muscular pathologies involving oxidative stress and elevated TNF levels cause muscle protein catabolism and impair myogenesis. This study found that mitoROS play a role in this process by triggering and enhancing mitophagy during myogenesis. Treatment with TNF before myogenesis decreases myoblast fusion and MYH2 synthesis, but antioxidants and autophagy suppression can partially restore myogenesis.

Summary: Mitochondria play a crucial role in tumor progression, with dysfunctional mitochondria contributing to proliferation of tumor cells in harsh environments. The activation of the UPRmt pathway through mitochondrial-nucleus retrograde signaling enhances carcinoma progression by reprogramming molecular metabolism.

Summary: Preservation of mitochondrial quality is crucial for cellular homeostasis. The processes of mitophagy and MRR are interlinked to prevent or compensate for mitochondrial defects. Transcription factors play a key role in signaling from mitochondria to the nucleus, driving gene expression to adapt to compromised homeostasis.

Summary: Age-related macular degeneration (AMD) is the leading cause of blindness among the elderly and currently has no treatment for early disease. This study found that decreased PINK1 in the retinal pigment epithelial (RPE) of early AMD eyes leads to impaired mitophagy and mitochondrial function, triggering death-resistant epithelial-mesenchymal transition (EMT). Additionally, the study found that an antioxidant dendrimer can inhibit EMT, providing a potential therapy for early AMD.

Summary: Incomplete radiofrequency ablation (iRFA) leads to the survival of cells that contribute to hepatocellular carcinoma (HCC) recurrence. This study investigated the role of reactive oxygen species (ROS) in HCC cells exposed to sublethal heat stress. It was found that sublethal heat stress induced a burst of ROS, which was initiated by upregulated NOX4 expression in mitochondria. The increased ROS triggered PINK1-dependent mitophagy to protect cells from apoptosis.

Summary: In this study, the researchers investigate the role of Parkin and USP30 in regulating the AKT/mTOR signaling during mitophagy. They found that Parkin inhibits AKT/mTOR signaling, while USP30 antagonizes the activity of Parkin to sustain AKT/mTOR activity.

Summary: Charcot-Marie-Tooth disease (CMT) is a group of inherited peripheral nerve disorders characterized by muscle weakness, sensory loss, foot deformities and gait abnormalities. Missense mutations in the HSPB8 gene have been associated with hereditary neuropathies, including CMT. In this study, HSPB8 mutant-induced neuropathies were modeled in Drosophila, revealing motor defects and mitochondrial dysfunction. The motor defects and mitochondrial dysfunction were restored by PINK1 and parkin, as well as a small molecule called kinetin riboside.

Summary: DJ-1 is a causative gene of early-onset familial Parkinson's disease (PD), and it influences the pathogenesis of sporadic PD by affecting reactive oxygen species (ROS) levels. PDK and PDP have been shown to play critical roles in protecting against oxidative stress by regulating glucose metabolism in the mitochondria, which is a major source of intracellular ROS.
