Abstract
This study focuses on the comparative metabolic profiling and effects of two steroid types: natural and synthetic, specifically 17α-methyl testosterone (17α-MT) at varying concentrations (1.5, 2, and 3 mg/kg) in rainbow trout (Oncorhynchus mykiss). Over a 75-day feeding trial, growth metrics, such as feed efficiency, daily specific growth, live weight gain, total weight gain, and survival rate were systematically monitored every 15 days. At the end of the feeding trial, histopathology, immunohistochemistry, and metabolome analyses were performed in the high-concentration groups (3 mg/kg natural and 3 mg/kg synthetic), in which the lowest survival rate was determined. Key findings reveal that the type of hormone significantly influences growth parameters. While some natural steroids enhanced certain growth aspects, synthetic variants often yielded better results. The metabolomic analysis highlighted significant shifts in the metabolism of tryptophan, purine, folate, primary bile acids, phosphonates, phosphinates, and xenobiotics via cytochrome P450 pathways. Histopathologically, the natural hormone groups showed similar testicular, hepatic, muscular, gill, cerebral, renal, and intestinal tissue structures to the control, with minor DNA damage and apoptosis observed through immunohistochemistry. Conversely, the synthetic hormone groups exhibited moderate DNA damage and mild degenerative and necrotic changes in histopathology.

Abstract
A rapid and sensitive assessment of the toxicity of oxygenated polycyclic aromatic hydrocarbons (OPAHs), widely distributed persistent organic pollutants in the environment, is crucial for human health. In this study, using high-performance liquid chromatography, the separation and detection of four purines, xanthine (X), guanine (G), adenine (A), and hypoxanthine (HX) in cells were performed. The aim was to evaluate the cytotoxicity of three OPAHs, namely 1,4-benzoquinone (1,4-BQ), 1,2-naphthoquinone (1,2-NQ) and 9,10-phenanthrenequinone (9,10-PQ), with higher environmental concentrations, from the perspective of purine nucleotide metabolism in human skin fibroblast cells (HFF-1). The results revealed that the levels of G and A were low in HFF-1 cells, while the levels of HX and X showed a dose-response relationship with persistent organic pollutants concentration. With increased concentration of the three persistent organic pollutants, the purine metabolism in HFF-1 cells weakened, and the impact of the three persistent organic pollutants on purine metabolism in cells was in the order of 9,10-PQ > 1,4-BQ > 1,2-NQ. This study provided valuable insights into the toxic mechanisms of 1,4-BQ, 1,2-NQ and 9,10-PQ, contributing to the formulation of relevant protective measures and the safeguarding of human health.
