Effects of ifosfamide and cisplatin exposure combined with a climate change scenario on the transcriptome responses of the mussel Mytilus galloprovincialis

Coastal ecosystems are currently exposed to pollutants and climate change. Namely, the increasing consumption of antineoplastic drugs and their potential release to aquatic ecosystems are raising concerns. Nevertheless, information regarding the toxicity of these drugs towards non-target species is scarce, especially considering climate change scenarios. Ifosfamide (IF) and cisplatin (CDDP) are among the antineoplastics already detected in aquatic compartments and due to their mode of action (MoA) can negatively affect aquatic organisms. This study evaluates the transcription of 17 selected target genes related to the MoA of IF and CDDP in Mytilus galloprovincialis gills exposed to environmentally relevant and toxicological meaningful concentrations (IF - 10, 100, 500 ng/L; CDDP - 10, 100, 1000 ng/L), under an actual (17 °C) and predicted warming scenario (21 °C). Results showed an upregulation of the cyp4y1 gene when exposed to the highest concentrations of IF, regardless of the temperature. Both drugs upregulated genes related to DNA damage and apoptosis (p53, caspase 8 and gadd45), especially under warmer conditions. Increased temperature also downregulated genes related to stress and immune responses (krs and mydd88). Therefore, the present results showed a gene transcriptional response of mussels to increasing concentrations of antineoplastics and that warmer temperatures modulated those effects.
