Effects of water temperature increase on gene expression, biochemical, and histopathological responses of the bivalve species Mytilus galloprovincialis to the antineoplastic drug 5-fluorouracil
The present study aimed to assess the potential ecotoxicological effects of 5-fluorouracil (5-FU), an antineoplastic already found in aquatic ecosystems, towards the bivalve Mytilus galloprovincialis, considering actual and warming temperature scenarios. To this end, organisms were exposed for 28 da...

To this end, organisms were exposed for 28 days to increasing 5-FU concentrations (10, 100, and 500 ng/L) at control (17 ± 1.0 °C) and warming (21 ± 1.0 °C) temperatures. Transcriptomic of selected target genes, biochemical responses, and histopathological alterations were used to assess possible detrimental effects. Results showed an overall down-regulation of mRNA transcripts related to xenobiotic metabolization pathways and cell apoptosis in organisms exposed to 5-FU, especially at 21 °C. While at 17 °C, the antioxidant defenses were not enough to avoid cell damage caused by 5-FU, at 21 °C the metabolic slowdown avoided further cell damage. However, histopathological alterations in the digestive gland at 21 °C at high concentrations of 5-FU were observed. Overall, the present results indicate that the warming temperature may enhance the detrimental effects of 5-FU on this species, with metabolism being particularly affected.Vanessa Queirós (https://doi.org/10.54499/PD/BD/150590/2020) and Carla Leite (https://doi.org/10.54499/2020.05296.BD) benefited from a PhD grant given by the National Funds through the Portuguese Science Foundation (Fundação para a Ciência e a Tecnologia, FCT).
