Abstract

As cynobacterial blooms frequently occur in fresh waters throughout the world, microcystins (MCs) have caused serious damage to both wildlife and human health. MCs are known to have developmental toxicity, however, the possible molecular mechanism is largely unknown. This is the first toxicological study to integrate post-transcriptomic, proteomic and bioinformatics analysis to explore molecular mechanisms for developmental toxicity of MCs in zebrafish. After being microinjected directly into embryos, MC-RR dose-dependently decreased survival rates and increased malformation rates of embryos, causing various embryo abnormalities including loss of vascular integrity and hemorrhage. Expressions of 31 microRNAs (miRNAs) and 78 proteins were significantly affected at 72 hours post-fertilisation (hpf). Expressions of miR-430 and miR-125 families were also significantly changed. The altered expressions of miR-31 and miR-126 were likely responsible for the loss of vascular integrity. MC-RR significantly reduced the expressions of a number of proteins involved in energy metabolism, cell division, protein synthesis, cytoskeleton maintenance, response to stress and DNA replication. Bioinformatics analysis shows that several aberrantly expressed miRNAs and proteins (involved in various molecular pathways) were predicted to be potential MC-responsive miRNA-target pairs, and that their aberrant expressions should be the possible molecular mechanisms for the various developmental defects caused by MC-RR.

Abstract

Studies have demonstrated that microcystins (MCs) can act as potential carcinogens and have caused serious risk to public environmental health. The molecular mechanisms of MC-induced susceptibility to carcinogenesis are largely unknown. In this study, we performed for the first time a comprehensive analysis of changes in microRNAs (miRNAs) and proteins expression in livers of mice treated with MC-LR. Utilizing microarray and two-dimensional gel electrophoresis (2-DE) analysis, we identified 37 miRNAs and 42 proteins significantly altered. Many aberrantly expressed miRNAs were related to various cancers (e.g., miR-125b, hepatocellular carcinoma; miR-21, leukemia; miR-16, chronic lymphocytic leukemia; miR-192, pituitary adenomas; miR-199a-3p, ovarian cancer; miR-34a, pancreatic cancer). Several miRNAs (e.g., miR-34a, miR-21) and proteins (e.g., TGM2, NDRG2) that play crucial roles in liver tumorigenesis were first found to be affected by MC-LR in mouse liver. MC-LR also altered the expression of a number of miRNAs and proteins involved in several pathways related to tumorigenesis, such as glutathione metabolism, VEGF signaling, and MAPK signaling pathway. Integration of post-transcriptomics, proteomics, and transcriptomics reveals that the networks miRNAs and their potential target genes and proteins involved in had a close association with carcinogenesis. These results provide an early molecular mechanism for liver tumorigenesis induced by MCs.
