An 11-year-old girl with quiescent ulcerative colitis had sustained elevation of liver enzymes. Although she had no clinical symptoms suggestive of Wilson's disease, such as Kayser-Fleischer rings, laboratory data showed decreased serum copper and ceruloplasmin levels and increased urinary copper excretion. Genetic testing showed pathogenic variants in allele 1: c.

Disturbances in intracellular copper (Cu) homeostasis can trigger cuproptosis, a new form of cell death, which, when combined with photothermal therapy (PTT), offers a promising solution to the persistent challenges in colorectal cancer (CRC) treatment. In this study, a "three-level nanoparticle rocket" strategy is developed by engineering CuO, a multifunctional Cu-based nanoenzyme that is photothermal and has electron transfer properties and antioxidant efficiency. CuO effectively remodels the inflammatory environment by scavenging reactive oxygen species, thereby overcoming the traditional limitations of PTT.

Methods: The gene expression dataset GSE89632 was retrieved from the Gene Expression Omnibus database to identify differentially expressed genes (DEGs) between the non-alcoholic steatohepatitis (NASH) group and the healthy group using the 'limma' package in R software and weighted gene co-expression network analysis. Gene ontology, kyoto encyclopedia of genes and genomes pathway, and single-sample gene set enrichment analyses were performed to identify functional enrichment of DEGs.
LOX-induced tubulointerstitial fibrosis via the TGF-β/LOX/Snail axis in diabetic mice.

Background: The partial epithelial-mesenchymal transition (EMT) is emerging as a significant mechanism in diabetic nephropathy (DN). LOX is a copper amine oxidase conventionally thought to act by crosslinking collagen. However, the role of LOX in partial EMT and fibrotic progression in diabetic nephropathy has not been investigated experimentally.

Phenolic compounds are typical organic pollutants which cause severe human health problems due to their teratogenesis, carcinogenesis, neurotoxicity, immunotoxicity and endocrine disruption. Natural laccase is a multicopper oxidase existing in bacteria, plants, and insects, which can accelerate the transformation of phenolic compounds to their less hazardous oxidized products under mild conditions without harmful byproducts. Despite eco-environmentally friendly property of laccase, it still faces constraints of widespread application attribute to its high cost, complex preparation, and vulnerability.
