Article Title: Furosemide reduces BK-αβ4-mediated K + secretion in mice on an alkaline high-K + diet
Figure Lengend Snippet: Furosemide (Furo) effect on urine pH. Urine pH of wild-type (WT; A) and β4-knockout (β4-KO; B) on day −1, 1, 4, 7, and 11 of control (Ctrl) and Furo treatments or on day −1, 1, 4, and 7 of Furo + acetazolamide (Actz) treatment. *P < 0.05 vs. HK + Ctrl water, #P < 0.05 vs. Day –1, analyzed with two-way repeated-measures ANOVA with a post hoc Holm-Sidak test (P < 0.001 for both treatment and days with interaction P < 0.01). n = 12–14 for WT Ctrl and Furo; N = 7 – 8 for β4-KO Ctrl and Furo; N = 4 for WT Furo + Actz; n = 3 for β4-KO Furo + Actz.
