Figure 2. Expression of ENaC proteins.
A. Representative Western blots. α (90 kDa), β (95 kDa) and γ ENaC protein signals are found in blots probed with specific antibodies against α (Santa Cruz, sc-22239), β (Santa Cruz, sc-21013), and γ (Abcam, ab3468) subunits. B. Total expression levels of ENaC subunits. β actin is used as a loading control. C & D. Expression of ENaC proteins in ATI and ATII cells. The expression levels of ENaC proteins related to AQP5 (C) and pro-SPC (D) were adjusted to compensate for the alterations in AQP5 and pro-SPC (dotted bars). One-way ANOVA. *P<0.05 and ***P<0.001 versus control groups.
