Article Abstract
As the relationship between exposure to chemical carcinogens and human health risks becomes increasingly clear, identifying effective biomarkers to reveal early exposure and prevent the occurrence and development of tumors has become particularly critical. Ribosomal DNA (rDNA), a cluster of genes encoding ribosomal RNA, has emerged as a focal point in chemical carcinogen exposure research in recent years, due to its high copy number within cells and sensitivity to environmental stimuli. The dynamic changes in rDNA copy numbers, especially the significant alterations observed following exposure to environmental carcinogens, have rendered it a promising potential biomarker. This paper aims to systematically review the theoretical underpinnings and research progress of rDNA copy numbers as a biomarker for exposure to chemical carcinogens, and further discuss the challenges and prospects in future research and applications.

Noble metal nanoparticles (NPs), particularly platinum (Pt), are widely used in heterogeneous catalysis due to their exceptional activity. However, controlling their size and preventing sintering during synthesis remains a major challenge, especially when aiming for high dispersion and stability on supports such as graphene. Atomic layer deposition (ALD) has emerged as a promising method to address these issues, yet conventional processes often lead to broad particle size distributions (PSDs).

Wheat, a significant source of protein, can also induce various wheat-related allergic reactions (WRARs). Statistical data show significant spatiotemporal and geographical variations in the prevalence of WRARs. Studies reveal that hexaploid wheat exhibits notably higher allergenicity.

Objective: This study employs integrated network toxicology and molecular docking to investigate the molecular basis underlying 4-nonylphenol (4-NP)-mediated enhancement of breast cancer susceptibility.
Methods: We integrated data from multiple databases, including ChEMBL, STITCH, Swiss Target Prediction, GeneCards, OMIM and TTD. Core compound-disease-associated target genes were identified through Protein-Protein Interaction (PPI) network analysis.

Heart failure (HF) and lung cancer (LC) often coexist, yet their shared molecular mechanisms are unclear. We analyzed transcriptome data from the NCBI Gene Expression Omnibus (GEO) database (GSE141910, GSE57338) to identify 346 HF‑related differentially expressed genes (DEGs), then combined weighted gene co-expression network analysis (WGCNA) pinpointed 70 hub candidates. Further screening of these 70 hub candidates in TCGA lung cancer cohorts via LASSO, Random Forest, and multivariate Cox regression suggested CYP4B1 as the only independent prognostic marker.

Tattoos and permanent make-up (PMU) gain increasing popularity among the general population. There are indications that pigments or their fragments may translocate within the body, however knowledge about possible systemic adverse effects related to tattoos is very limited. We investigated the prevalence of systemic chronic health effects including cardiovascular diseases, cancer and liver toxicity and their relationship with the presence and characteristics of tattoos and PMU as part of the LIFE-Adult-study, a population-based cohort study.
