Figure Lengend Snippet: Expression of BPIFB4 and key proteins in the PI3K/AKT pathway in COPD mice. ( a ) Illustration for COPD mouse models. ( b , c ) Western blot analysis of BPIFB4 ( n = 10/group), PI3K, p-PI3K, AKT1, and p-AKT1 ( n = 3/group) in the lung tissues of COPD mice and controls. ( d ) BPIFB4 mRNA expression assessed by RT-qPCR ( n = 10/group). ( e , f ) Statistical significance: ns represented not significant, *** P < 0.001, and **** P < 0.0001, versus controls.
