title: RNA-seq analysis reveals genes underlying resistance to porcine circovirus type 2 infection in pigs showing different disease responses
design: Five weaned Yorkshire × Landrace (YL) 6-week-old (on average) pigs were randomly sampled and injected intramuscularly with 3mL PBS as control. At 35 days after injection, the pigs were killed. Total RNA was extracted from the lung tissues of four YL pigs. And equal amounts of RNA from each of the four samples were mixed to build the library.
