Characterization of the porcine p65 subunit of NF-κB and its association with virus antibody levels
2011
Abstract NF-κB p65 subunit plays important roles in controlling both innate and adaptive immunity. Here we report the characterization of porcine NF-κB p65 subunit (pp65). pp65 shows high similarity to other mammalian counterparts. pp65 mRNA expression was mainly observed in lung, spleen, liver and small intestine. Furthermore, overexpression of pp65 activates NF-κB in porcine endothelial cell line PIEC, porcine alveolar macrophages cell line 3D4/21 and porcine primary fetal fibroblasts. A COOH-terminal truncation derivative of pp65 (pp65RHD) has been identified as a specific transdominant inhibitor of NFκB. Association study was performed on the selected SNP and indel. The results revealed that the SNP BglI was significantly associated ( P
