| Title |
Exposure to mixture of Environmental endocrine disruptors induce miRNAs/isomiRs deregulation in mouse testis |
| Organism |
Mus musculus |
| Experiment type |
Non-coding RNA profiling by high throughput sequencing
|
| Summary |
Purpose: In testis the effects of exposure to mixtures of Endocrine disruptors compounds (EDCs) upon expression of miRNAs were not addressed.
Objective: To identify the expression profiles of the 'miRNome' in mice testis chronic exposed to a defined mixture of five EDCs.
Methods: Pregnant mice from 0.5 post-coital day were exposed in the drinking water to a mixture containing 0.3 mg/Kg-bw/day of each phthalate (DEHP, DBP, BBP), plus 0.05 mg/Kg-bw/day of each alkylphenol (NP, OP) until adulthood of male mouse (60 days old). We characterized the 'miRNome' by next generation sequence (NGS).
Results: In mouse testis exposed to EDCs mixture we detected by NGS 2 up-regulated and 8 down-regulated miRNAs along to 36 isomiRs differentially expressed; these results were validated by RT-qPCR. and functional analysis showed deregulation of testicular hormonal status, spermatogenesis disruption and germ cells apoptosis.
Conclusions: Here we provide the first association between deregulation of miRNAs, isomiRs, with histopathological and hormonal alterations in adult mice testis exposed to mixture of EDCs.

| Overall design |
Testis snc-RNA profiles of 60-day old mice of control (mice drank water only with the dose of vehicles equivalents diluted) and exposed to EDCs mixture were generated by deep sequency using MiSeq-Illumina sequencer
