Through previous literature studies, we found that miR-124-3p may be associated with hypertension. Therefore, we investigated the relationship between miR-124-3p and hypertension in Human Umbilical Vein Endothelial Cells (HUVECs) induced by angiotensin II (AngII). AngII-induced HUVECs model was constructed and the expression of miR-124-3p was detected by qRT-PCR. After transfected cells, apoptosis and ROS production were detected by flow cytometry, caspase-3 kit, and DCFH-DA staining. The target genes of miR-124-3p were predicted and verified by TargrtScan, Luciferase assay, qRT-PCR, and western blot. After silencing Early growth response factor 1 (siEGR1), its effects on apoptosis and ROS production were explored. Finally, the rescue experiments were conducted to explore the mechanism of miR-124-3p to reduce hypertension. MiR-124-3p was underexpressed in the cell model. In Ang II-induced HUVECs, the number of apoptosis increased, the content of caspase-3 was higher, and ROS production increased. However, these effects could be partially inhibited by miR-124-3p mimic. EGR1 was down-regulated by miR-124-3p, and siEGR1 was able to inhibit apoptosis and ROS production of cell model. In the final rescue experiments, miR-124-3p partially reversed the effect of Ang-II on the viability, migration, invasion and apoptosis and ROS production in HUVECs by down-regulating EGR1. MiR-124-3p inhibits Ang II-induced apoptosis and ROS production in HUVECs by down-regulating EGR1.

The present study has evaluated different soybean genotypes to understand the salt and drought tolerance mechanisms based on physiological traits (photosynthesis, stomatal conductance, chlorophyll, and cell membrane stability), antioxidant enzymes (superoxide dismutase, catalase, and peroxidase), reactive oxygen species (HO and O ), osmolytes (glycine betaine, proline, and Na/K), plant water relations (relative water content, water potential, and solute potential) and expression of related genes (, , , , , , , and ). The experiment was conducted in a two-factorial arrangement using randomized complete block design (RCBD) with genotypes as one factor and salt, drought, and control treatments as the other factor. All physiological traits, relative water content, and water potential decreased significantly in all soybean genotypes due to individual and combined treatments of drought and salt stress, with significantly less decrease in soybean genotypes G4620RX, DM45X61, and NARC-21.

Background: Induced pluripotent stem cell (iPSC) technology has emerged as a powerful tool for disease modeling, providing an innovative platform for investigating disease mechanisms. iPSC-derived organoids, including retinal organoids, offer patient-specific models that closely replicate in vivo cellular environments, making them ideal for studying retinal neurodegenerative diseases where retinal ganglion cells (RGCs) are impacted. N6-methyladenosine (m6A), a prevalent internal modification in eukaryotic mRNAs, plays a critical role in RNA metabolic processes such as splicing, stability, translation, and transport.

In recent years, the prevalence of extremely high-temperature climates, has led to an increase in cases of acute heat stress, which has been identified as a contributing factor to various kidney diseases. Fructose, the end product of the polyol pathway, has been linked to kidney conditions such as kidney stones, chronic kidney disease and acute kidney injury. However, the relationship between acute heat stress and kidney injury caused by endogenous fructose remains unclear.

In recent decades, significant advancements have been achieved in non-small cell lung cancer (NSCLC) treatment. However, drug resistance, postoperative recurrence, distant metastasis, and other critical issues arise during NSCLC treatment. Natural products play a crucial role in the development of anti-tumor drugs.

Delayed wound healing in patients with diabetes remains a major health challenge worldwide. Uncontrolled bacterial infection leads to excessive production of reactive oxygen species (ROS) and persistent inflammatory responses, which seriously hinder conventional physiological healing processes after injury. Biofilms, as protective barriers for bacteria, pose a critical obstacle to effective bacterial eradication.
