Abstract Cadmium has been identified as an environmental pollutant and a carcinogen. N 6 -methyladenosine (m A) plays crucial role in the development of lung tumors, but mechanisms remain incompletely clarified. In present study, our data demonstrated that prolonged treatment 1 μmol/L CdSO 4 for 40 passages bronchial epithelial cells (Beas-2B cells) resulted malignant phenotype, which manifested boosted proliferation, migration invasion capacity well apoptosis reduction. Proteomic assay revealed passage cells, 350 proteins showed differentially expressed comparison to control, these were primarily enriched Kyoto Encyclopedia Genes Genomes (KEGG) pathways “pathways cancer” “Chemical carcinoma-reactive oxygen species”. Moreover, mRNAs Nuclear factor kappa B ( NF-κB) p65 NAD(P)H: quinone oxidoreductase (NQO1) , key signaling molecules two pathways, predicted contain m A modification sites with high confidence.

Single-cell sequencing combined with urinary multi-omics analysis reveals that the non-invasive biomarker PRDX5 regulates bladder cancer progression through ferroptosis signaling

BMC Cancer, Journal Year: 2025, Volume and Issue: 25(1)

Published: March 24, 2025

This study aimed to elucidate the expression profile and biological implications of peroxidase 5 (PRDX5) in bladder cancer (BC), specifically investigating its influence on BC progression through modulation reactive oxygen species (ROS) levels activation ferroptosis pathways. We employed urine proteomics data transcriptomic information from Cancer Genome Atlas (TCGA) identify differentially expressed genes tissues, focusing PRDX5. Using single-cell RNA sequencing (scRNA-seq), we assessed PRDX5 distribution across various cell types tumor microenvironment. conducted vitro experiments analyze impact proliferation, migration, invasion, while exploring mechanisms modulating ROS ferroptosis. In vivo were performed observe PRDX5's signaling tissue contexts. found significant upregulation with scRNA-seq revealing enrichment epithelial cells, correlating disease advancement established markers. analyses showed that overexpressed enhanced invasion knockout produced opposing effects. Additionally, modulated impacted confirmed inhibited growth activated pathways tissues. Our highlights elevated role promoting regulation may serve as a promising target for treatment, supporting further exploration potential clinical applications.

Arsenic exposure at environmentally relevant levels induced metabolic toxicity in development mice: Mechanistic insights from integrated transcriptome and metabolome

Environment International, Journal Year: 2024, Volume and Issue: 190, P. 108819 - 108819

Published: June 14, 2024

Emerging evidence has linked arsenic exposure and metabolic homeostasis, but the mechanism is incompletely understood, especially at relatively low concentrations. In this study, we used a mouse model to evaluate health impacts toxicity of in drinking water environmentally relevant levels (0.25 1.0 ppm). Our results indicated that damaged intestinal barrier induced accumulation, oxidative stress, pathological changes liver illum. Interestingly, increased hepatic triglyceride (TG) total cholesterol (TC), while reduced serum TG TC levels. The transcriptome found caused perturbation promoted lipid accumulation by regulating exogenous fatty acids degradation apolipoproteins related genes. metabolomics identified 74 88 differential metabolites 0.25 ppm, respectively. KEGG disease subcellular location analysis diseases, mitochondrion might be target organelle for arsenic-induced toxicity. Co-enrichment metabolome 24 9 genes as biomarkers. Moreover, 40 male (20 nonalcoholic (NAFLD) cases 20 healthy controls) was further selected validate our findings. Importantly, significantly changed L-palmitoylcarnitine, 3-hydroxybutyric acid, 2-hydroxycaproic acid 6 Hadha, Acadl, Aldh3a2, Cpt1a, Cpt2, Acox1 were NAFLD cases. from integrated multi-omics chemical-protein network L-palmitoylcarnitine played critical role mitochondrial β-oxidation (Cpt1a, Cpt2). conclusion, these findings provided new clues levels, which involved late-life development. also contribute understanding human responses phenotypic hazardous material environment.
