Printer emitted particles (PEPs) exposed rat blood mRNA expression profiling

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, 13, 17 and 21 days for blood collection.将大鼠暴露于打印机排放颗粒物（printer emitted particles，PEPs）与高效空气过滤器（High Efficiency Particulate Air，HEPA）过滤空气中，其中前者为暴露组，后者为对照组。于第1、5、9、13、17及21天处死动物并采集血液样本。
