Blood gas status and urine pH in WT and Adgrf5^−/− mice. a The partial pressures of O₂ (pO₂) and CO₂ (pCO₂) and pH in arterial blood of WT and Adgrf5^−/− mice (12-weeks-old) were measured using a blood gas analyzer (ABL 505 Radiometer). Bicarbonate (HCO₃⁻) concentrations were calculated from the pCO₂ and pH data. Values are presented as the mean ± SEM (n = 7). *p < 0.05. b The pH of urine collected from WT and Adgrf5^−/− mice (10-weeks-old) was determined using a grass electrode. Data are presented as the mean ± SEM (n = 6). **p < 0.001
