SOD1 and mastitis: The genes CD-14, CCL2, β defensin, SPP1, BP1, A2M, TLR7, and TLR8 are significantly more expressed in mastitis-affected goats than in resistant goats; on the other hand, the genes ATP1A1, SOD1, CAT, AhpC/TSA, PRDX2, PRDX4, NQO1, and Nrf2 are significantly less expressed in mastitis-affected goats than in resistant goats [47].
