Chinese giant salamander Bcl-w: An inhibitory role in iridovirus-induced mitochondrial apoptosis and virus replication.

ABSTRACT: B-cell lymphoma-2 (BCL-2) superfamily molecules play crucial roles in mitochondrial apoptosis induced by Chinese giant salamander iridovirus (GSIV). As an anti-apoptotic molecule in the BCL-2 family, the molecular mechanism of Bcl-w during GSIV infection remains unknown. In this study, we characterized for the first time an amphibian Bcl-w from Chinese giant salamander Andrias davidianus (AdBcl-w), and its function and regulatory mechanism during GSIV infection were investigated. AdBcl-w possesses the conserved structural features of Bcl-w and shares 35-54% sequence identities with other Bcl-w. mRNA expression of AdBcl-w was most abundant in liver and muscle. The AdBcl-w mRNA expression was regulated during GSIV infection. Western blotting assays revealed that the level of Bcl-w protein wa
