Ang II effects in old mice. Representative immunoblots for NCC and α-ENaC (A), and β- and γ-ENaC (B) in whole kidney homogenates from old (O) ∼21-month-old male (M) and female (F) control (C) or Ang II-infused (A) mice. Equal amounts of total protein were loaded in each lane, and each lane represents a different mouse (shown are 3 mice per group). C–F Densitometry summaries of NCC, α-, β- and γ-ENaC, respectively (n = 6 mice/group), as indicated. Significantly different (p < 0.05) from * OMC and ^τ OFC (1-way ANOVA).
