GNE and infection: As a result of ASAL*lice interaction, lice infection up-regulated glucosamine (UDP-N-acetyl)-2-epimerase/N-acetylmannosamine kinase (gne) only in the ASAL-injected salmon (i.e., ASAL/lice > ASAL/no lice; Figures 8C, R), and down-regulated mmp13a only in the PBS-injected salmon (i.e., PBS/lice < PBS/no lice; Figures 8E, R), and PBS/lice salmon showed higher sesn1a mRNA levels than the rest of the injection/infection groups (Figures 8P, R).
