Acute kidney injury (AKI) is a clinical syndrome characterized by rapid and significant decrease in renal function that can arise from various etiologies, associated with high morbidity mortality. The tubular epithelial cells (TECs) represent the central cell type affected AKI, their notable regenerative capacity critical for recovery of afflicted patients. adaptive repair process initiated surviving TECs following mild AKI facilitates full recovery. Conversely, when severe or persistent, it allows to undergo pathological responses, abnormal phenotypic transformation, which will lead development fibrosis. Given implications fate after outcomes, deeper understanding these mechanisms necessary identify promising therapeutic targets biomarkers human kidney.

This study aims elucidate metabolism- pyroptosis-related differentially expressed genes (EMAPRDEGs) development. EMAPRDEGs were identified by querying GeneCards Gene Expression Omnibus (GEO) databases. Subsequent analyses included Ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) enrichment, Set Enrichment Analysis (GSEA), Protein-Protein Interaction (PPI) network analysis. Additionally, mRNA-miRNA, mRNA-drug, mRNA-transcription factor (TF) interaction networks constructed. Differential expression receiver operating characteristic (ROC) curve performed evaluate diagnostic potential EMAPRDEGs. Immune cell infiltration was assessed using ssGSEA algorithm, levels tissues validated quantitative real-time PCR (qRT-PCR). Thirteen identified, with GO KEGG indicating their involvement pathways.

Acute kidney injury (AKI) is a life-threatening condition characterized by rapid decline in the renal function, primarily caused oxidative stress, inflammation, and ferroptosis. Herein, we present selenium-doped carbon dots (Zt-SeCDs) that integrate antioxidant activity with controlled release of Zileuton, 5-lipoxygenase (ALOX5) inhibitor, under high reactive oxygen species (ROS) conditions. This nanoplatform can efficiently deliver leveraging its inherent properties to achieve targeted prevention treatment AKI. In vitro studies have confirmed Zt-SeCDs eliminate excessive ROS, prevent ferroptotic cell death, modulate inflammatory responses reducing expression key pro-inflammatory cytokines. Additionally, regulate ferroptosis through suppression ALOX5 upregulation glutathione peroxidase 4 (GPX4) expression. The significantly improves promotes regeneration damaged tissue, alleviates processes, death. Moreover, monitoring serum indicators observing pathological changes further potential preventing Notably, activate AMPK/FoxO1 signaling pathway, enhancing endogenous defenses protect tissue from damage. promising not only holds significant promise for AKI, but also aims facilitate clinical application.

Abstract Diabetic kidney disease (DKD), one of the most prevalent microvascular complications diabetes, arises from dysregulated glucose and lipid metabolism induced by hyperglycemia, resulting in deterioration renal cells such as podocytes tubular epithelial cells. Programmed cell death (PCD), comprising apoptosis, autophagy, ferroptosis, pyroptosis, necroptosis, represents a spectrum demise processes intricately governed genetic mechanisms vivo. Under physiological conditions, PCD facilitates turnover cellular populations serves protective mechanism to eliminate impaired or cells, thereby preserving tissue homeostasis amidst hyperglycemic stress. However, existing research predominantly elucidates individual modes death, neglecting intricate interplay mutual modulation observed among various forms PCD. In this comprehensive review, we delineate diverse regulatory governing elucidate crosstalk dynamics distinct pathways. Furthermore, review recent advancements understanding pathogenesis explore their implications DKD. Additionally, potential natural products derived primarily botanical sources therapeutic agents, highlighting multifaceted effects on modulating crosstalk, proposing novel strategies for DKD treatment.
