T1 |
151-354 |
DRI_Background |
denotes |
Cyanobacterial blooms threaten human health as well as the population of other living organisms in the aquatic environment, particularly due to the production of natural toxic components, the cyanotoxin. |
T2 |
416-636 |
DRI_Outcome |
denotes |
In this study, the hepatic alterations at histological, proteome and transcriptome levels were evaluated in female and male medaka fish chronically exposed to 1 and 5 μg L(-1) microcystin-LR (MC-LR) and to the extract of |
T3 |
662-863 |
DRI_Outcome |
denotes |
aeruginosa PCC 7820 (5 μg L(-1) of equivalent MC-LR) by balneation for 28 days, aiming at enhancing our understanding of the potential reproductive toxicity of cyanotoxins in aquatic vertebrate models. |
T4 |
864-986 |
DRI_Outcome |
denotes |
Indeed, both MC and Microcystis extract adversely affect reproductive parameters including fecundity and egg hatchability. |
T5 |
987-1077 |
DRI_Background |
denotes |
The liver of toxin treated female fish present glycogen storage loss and cellular damages. |
T6 |
1078-1185 |
DRI_Background |
denotes |
The quantitative proteomics analysis revealed that the quantities of 225 hepatic proteins are dysregulated. |
T7 |
1186-1344 |
DRI_Background |
denotes |
In particular, a notable decrease in protein quantities of vitellogenin and choriogenin was observed, which could explain the decrease in reproductive output. |
T8 |
1345-1532 |
DRI_Approach |
denotes |
Liver transcriptome analysis through Illumina RNA-seq reveals that over 100-400 genes are differentially expressed under 5 μg L(-1) MC-LR and Microcystis extract treatments, respectively. |
T9 |
1533-1802 |
DRI_Background |
denotes |
Ingenuity pathway analysis of the omic data attests that various metabolic pathways, such as energy production, protein biosynthesis and lipid metabolism, are disturbed by both MC-LR and the Microcystis extract, which could provoke the observed reproductive impairment. |
T10 |
1803-1932 |
DRI_Outcome |
denotes |
The transcriptomics analysis also constitutes the first report of the impairment of circadian rhythm-related gene induced by MCs. |
T11 |
1933-2283 |
DRI_Outcome |
denotes |
This study contributes to a better understanding of the potential consequences of chronic exposure of fish to environmental concentrations of cyanotoxins, suggesting that Microcystis extract could impact a wider range of biological pathways, compared with pure MC-LR, and even 1 μg L(-1) MC-LR potentially induces a health risk for aquatic organisms. |
