At 28 days post-infection, qPCR results showed that miR-27a antagomir treatment dramatically suppressed miR-27a expression in lung tissues and spleens of the mice, and increased the expression of Plk2 and Pink1, the two characterized miR-27a’s targets, in the lung tissues (Supplementary Fig. 5d and e)40,41. The gene discussed is PINK1; the disease is infection.
