SIL1 and mastitis: Among the highly connected genes in the magenta module, GCLM (Wang K. et al., 2016), PARK7 (Donaldson et al., 2005), SIL1 (Li et al., 2019), PHB (Genini et al., 2011), and CD68 (Bilir et al., 2012) were potentially associated with mastitis or similar biological processes, based on the previous studies.
