BFSP1 and infection: Genes (NEB, MYOM2, MYOZ1, and MYBPC1) coding for cytoskeleton elements were downregulated, while other genes (KRT13, KRT17, KRT6A, and BFSP1) were upregulated along with higher abundance of the proteins (PLEC, KRT2, and PLXNA4) after infection with swH1N1 compared to both control pigs and pigs infected with huH1N1.
