SOAT1 and mastitis: Noticeably, several other pathways primarily involved in pro-inflammatory and innate immune system were uncovered in the present study but not in Wang et al. (2013), including cytokine-cytokine receptor interaction, Jak-STAT signaling pathway (FDR = 0.05; Figure S5) and Toll-like receptor signaling pathway, all of which were also demonstrated to be associated with S. aureus mastitis in both dairy cows and goats by previous studies (Pisoni et al., 2010; He et al., 2016).
