Sirt1 protects against lipopolysaccharide-induced injury in mouse type Ⅱ alveolar epithelial cells by deacetylating RelA/p65 subunit of nuclear factor-κB
Objective To determine whether nuclear factor-κB( NF-κB) are regulated by Sirtuin type 1( Sirt1) in mouse type Ⅱ alveolar epithelial cells( AEC Ⅱs) following exposure to lipopolysaccharide( LPS). Methods Genetically modified mice with Sirt1 overexpression( Tg) and wild-type( WT) mice were bred and the genotypes of the offspring mice were identified. The expression levels of Sirt1 mRNA and protein in the lung tissues of Tg mice and WT mice were compared using qRT-PCR and Western blotting. Tg mice and WT mice...
