Figure 2From: iTRAQ-proteomics and bioinformatics analyses of mammary tissue from cows with clinical mastitis due to natural infection with Staphylococci aureusExpression and localization of bovine COL1A1 and ITIH4 proteins. a, b: The localization and expression of COL1A1 in the healthy cow (HC) and mastitis cow’s (MC) mammary gland tissues by immunohistochemical staining. Brown indicates the positive COL1A1 protein expression; blue presents the negative. d, e: The localization and expression of ITIH4 in the HC and MC group’s mammary gland tissues by immunohistochemical staining. Brown indicates the positive ITIH4 protein; blue presents the negative. c, f: The results of Western blotting reveal the significant increase of COL1A1 and ITIH4 proteins in MC group compared to HC group (p < 0.05).Back to article page
