Malaviya P et. al. (February 2024). Diabetic Retinopathy and Regulation of Mitochondrial Glutathione-Glutathione Peroxidase Axis in Hyperhomocysteinemia Antioxidants (Basel). 13(3)
The article explores how hyperhomocysteinemia exacerbates mitochondrial damage in diabetic retinopathy. It shows that elevated homocysteine levels reduce mitochondrial glutathione peroxidase (GPx) and glutathione (GSH), crucial for reducing hydrogen peroxide (H2O2) in mitochondria. This disruption is due to increased SAM levels, which hypermethylate the GPx1 promoter, decreasing the mitochondrial GPx/GSH pool. Targeting hyperhomocysteinemia could be a potential therapeutic strategy for mitigating mitochondrial dysfunction in diabetic retinopathy.

Boovarahan SR et. al. (April 2024). Ischemic preconditioning modulates the DNA methylation process of the rat heart to provide tolerance to withstand ischemia reperfusion injury and its associated mitochondrial dysfunction 3 Biotech. 14(4):121.
This study investigates how ischemic preconditioning (IPC) protects rat hearts from ischemia-reperfusion injury (I/R) by modulating DNA methylation. IPC reduces DNA hypermethylation and enzyme activity associated with DNA methylation (DNMT), providing cardioprotection. Blocking the PI3K pathway eliminates IPC's protective effects and increases DNA methylation. IPC-induced DNA hypomethylation regulates genes involved in apoptosis, mitochondrial function, and oxidative stress. These findings suggest that IPC regulates DNA methylation, potentially offering therapeutic targets for I/R injury in rat hearts.

ElBeck Z et. al. (March 2024). Epigenetic modulators link mitochondrial redox homeostasis to cardiac function in a sex-dependent manner Nat Commun. 15(1):2358.
The study investigates how mitochondrial redox balance affects cardiac function, particularly in relation to sex differences. It shows that mitochondrial isocitrate dehydrogenase (IDH2) plays a crucial role in antioxidant defense in cardiomyocytes, despite reduced expression in certain heart conditions. The study reveals a complex regulatory network involving IDH2, NRF2, and metabolites like 2-oxoglutarate and L-2-hydroxyglutarate, influencing heart function in heart failure. These insights could lead to more personalized treatments for heart failure by targeting reactive oxygen species (ROS).

Hu X et. al. (March 2024). Inhibition of ALKBH5 inhibits inflammation and excessive proliferation by promoting TRIM13 m6A modifications in glomerular mesangial cells Naunyn Schmiedebergs Arch Pharmacol.
The study explores how inhibiting ALKBH5, an m6A demethylase, affects inflammation and proliferation in glomerular mesangial cells (GMCs) in chronic glomerulonephritis (CGN). ALKBH5 inhibition reduces inflammation and excessive proliferation by promoting TRIM13 m6A modifications in GMCs. This study sheds light on potential therapeutic targets for CGN.

Jia D et. al. (March 2024). Abscisic acid activates transcription factor module MdABI5-MdMYBS1 during carotenoid-derived apple fruit coloration Plant Physiol.
The article investigates the role of abscisic acid (ABA) in fruit coloration in apples. Carotenoids are the main pigments responsible for fruit color, and the study focuses on the regulatory mechanism behind the color difference in mutant apple fruits. The research identifies MdMYBS1, an MYB transcription factor, as a key regulator of carotenoid synthesis and ABA accumulation. MdMYBS1 directly activates genes involved in carotenoid biosynthesis and ABA production. Additionally, the study reveals that MdABI5, a transcription factor, activates MdMYBS1, forming a regulatory cascade that enhances carotenoid production and ABA accumulation. These findings provide insights into improving fruit coloration and quality in apple breeding and cultivation.

Matsuda KM et. al. (March 2024). Dual blockade of interleukin-17A and interleukin-17F as a therapeutic strategy for liver fibrosis: Investigating the potential effect and mechanism of brodalumab Cytokine. 178:156587.
This study investigates the potential of blocking interleukin-17A (IL-17A) and interleukin-17F (IL-17F) as a therapy for liver fibrosis using brodalumab, an IL-17 receptor A (IL-17RA) blocker. Clinical data and animal studies suggest that blocking IL-17RA reduces liver fibrosis. In vitro experiments show that both IL-17A and IL-17F promote fibrosis-related gene expression in human liver cells. These findings suggest that dual blockade of IL-17A and IL-17F could be a promising strategy for treating liver fibrosis.

Desgeorges T et. al. (March 2024). Histone lactylation in macrophages is predictive for gene expression changes during ischemia induced-muscle regeneration Mol Metab. :101923.
The study examines the role of histone lactylation in macrophages during ischemia-induced muscle regeneration. Previous studies have shown lactate's importance in macrophage polarization. Using a mouse model of ischemia-induced muscle damage, the study examines macrophage dynamics and gene expression changes over time. They find that histone lactylation levels increase between 2 and 4 days post-injury, a crucial period for macrophage polarization. Changes in histone lactylation are associated with gene expression changes, suggesting that histone lactylation is functionally important for macrophage function during muscle regeneration.

Rong F et. al. (March 2024). Switching action modes of miR408-5p mediates auxin signaling in rice Nat Commun. 15(1):2525.
The article investigates how miR408-5p regulates auxin signaling in rice by switching between mRNA cleavage and translation repression modes. Under normal conditions, miR408-5p inhibits IAA30 protein translation, but in high auxin environments, it promotes IAA30 mRNA decay. This dynamic regulation is controlled by the miR156-IPA1 pathway and influenced by miR393, providing insights into complex miRNA networks in plants.
