Evidence of acquired resistance in neotropical fishes by the existence of an AHR-mediated CYP1A refractory phenotype.

Marine environmental research - 1 Sept 2026

López-Martínez Roxana Margarita, Stegeman John, Zanette Juliano

Abstract excerpt

Fish from several polluted environments in North America have been found to partially lose the ability to induce cytochrome P4501A (CYP1A) via aryl hydrocarbon receptor (AHR) activation, a characteristic known as CYP1A refractory phenotype. We aimed to determine whether such a phenotype might occur in neotropical fishes. Female Poecilia vivipara and Phalloceros caudimaculatus, livebearer fishes, were sampled from...
