Printer emitted particles (PEPs) exposed rat lung miRNA expression profiling

Printer emitted particles (PEPs)-induced cardiopulmonary adverse effects and health risks and the underlying mechanisms are unknown. The aim of this study was to perform genome-wide mRNA profiling in rat blood to identify non-invasive blood based biomarkers for medical and occupational surveillance. The rats were exposed to printer emitted particles PEPs (exposed) and high efficiency particulate air (HEPA) filtered air (control). Animals were sacrificed on 1, 5, 9, and 21 days for lung tissue collection. Printer emitted particles (PEPs) exposed rat lung miRNA expression profiling
