“…For example, the protein and mRNA expression of interleukin-8 have been associated with bovine mastitis (Lee et al, 2006). The effect of allelic substitution on the CCR2 rs41257559:C>T SNP on SCS is significant (Leyva-Baca et al, 2008), and CCL2 polymorphisms have been associated with increased risk of rheumatoid arthritis (Gonzalez-Escribano et al, 2003), acute pancreatitis (Papachristou et al, 2005), and myocardial infarction in humans (Dewald et al, 2005;McDermott et al, 2005). Analysis of bovine CXCR1 SNPs may contribute to the discovery of mastitis resistance-related genetic traits, because bacteria are the most common cause of mastitis in cattle.…”
