The Bladder as a Target for PCB Toxicity: Evidence from PCB Levels, Phase I Metabolite Levels, and Cytochrome P450 Expression Following Developmental Exposure to a Human-Relevant PCB Mixture in Mice.
Article in Chemical research in toxicology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Lower urinary tract dysfunction is multifactorial, yet the role of environmental exposure remains poorly investigated. Developmental exposure to polychlorinated biphenyls (PCBs) has been linked to altered voiding in mice; however, the disposition of PCBs in the bladder, their bioactivation, and their effects on cytochrome P450 (CYP) expression remain unclear. We exposed mice to an environmentally relevant PCB mixture via maternal diet during gestation and lactation (vehicle, 0.1, 1, or 6 mg/kg/day). Offspring were euthanized at 6 to 7 weeks of age. PCB and hydroxylated PCB (OH-PCB) levels were quantified in the bladder, liver, blood, and urine. CYP expression was measured in the bladder and liver. PCBs and OH-PCBs accumulated in all tissues in dose- and sex-dependent manners, with higher-chlorinated congeners (e.g., PCB118, PCB138, PCB153, and PCB180) preferentially retained. Females exhibited greater hepatic accumulation, reduced urinary elimination, and distinct CYP regulation characterized by increased hepatic and decreased bladder expression. These findings, for the first time, define the signature of PCBs and OH-PCBs in the bladder and reveal a sex-specific PCB disposition and CYP responses. Our results provide new mechanistic insights into developmental PCB exposure and its potential contribution to voiding dysfunction in wildlife, domestic animals, and humans.
