Abstract
The presence of pharmaceuticals in aquatic ecosystems and their impact on humans and the environment are growing concerns in environmental health. This study aimed to evaluate the potential reproductive effects of diclofenac, ibuprofen, and aspirin on dissociated ovarian and testicular cells from Arabian Sea bream, Acanthopagrus arabicus. The cells were exposed to varying concentrations of the pharmaceuticals for 48 h. Steroid (17-β-estradiol (E2) and 11-ketotestosterone (11-KT)) production by the cells was assessed at 0, 12, 24, and 48 h of the experiment. The findings showed that diclofenac did not impact the production of E2 and 11-KT by ovarian cells, but it did significantly decrease the secretion of 11-KT from testicular cells. Ibuprofen and aspirin, on the other hand, both increased the production of the studied steroid hormones by ovarian cells and reduced the secretion of 11-KT by testicular cells in a dose- and time-dependent manner. The pharmaceuticals studied were potent inhibitors of 11-KT secretion, particularly at higher concentrations in the cultured testicular cells. However, they were also found to stimulate steroid production from fish ovarian cells. In conclusion, the results suggest that analgesics (diclofenac, ibuprofen, and aspirin) have the potential to disrupt estrogen biosynthesis and impact reproduction in fish.
期刊介绍：
Toxicology in Vitro publishes original research papers and reviews on the application and use of in vitro systems for assessing or predicting the toxic effects of chemicals and elucidating their mechanisms of action. These in vitro techniques include utilizing cell or tissue cultures, isolated cells, tissue slices, subcellular fractions, transgenic cell cultures, and cells from transgenic organisms, as well as in silico modelling. The Journal will focus on investigations that involve the development and validation of new in vitro methods, e.g. for prediction of toxic effects based on traditional and in silico modelling; on the use of methods in high-throughput toxicology and pharmacology; elucidation of mechanisms of toxic action; the application of genomics, transcriptomics and proteomics in toxicology, as well as on comparative studies that characterise the relationship between in vitro and in vivo findings. The Journal strongly encourages the submission of manuscripts that focus on the development of in vitro methods, their practical applications and regulatory use (e.g. in the areas of food components cosmetics, pharmaceuticals, pesticides, and industrial chemicals). Toxicology in Vitro discourages papers that record reporting on toxicological effects from materials, such as plant extracts or herbal medicines, that have not been chemically characterized.
