Figure 2. Association of lncRNA PVT1 with airway smooth function of asthmatic mice. (A) PVT1 expression was determined within ASMCs that were extracted from mice models of saline+air (SA), saline+ozone (SO), OVA+air (OA) and OVA+ozone (OO) groups. *: P<0.05 when compared with SA group, #: P<0.05 when compared with saline+ozone group, &: P<0.05 when compared with OVA+air group. (B, C) Correlation matrixes were generated regarding PVT1 expression and airway smooth function in all asthmatic mice (B) and in asthmatic mice handled through 4 approaches (C).
