Tg8 mice are less sensitive to mild hypoxia than C3H mice. A, B, Plethysmographic recordings of respiration from a C3H mouse under normoxic (A, 21% O2) and hypoxic (B, 10% O2) conditions.C, The histograms show the mean variation (±SEM) of minute ventilation (ΔVE), tidal volume (ΔVT), and respiratory frequency (ΔfR) elicited by hypoxia in 20 C3H mice (white bars) and 24 Tg8 mice (black bars), expressed as percentage [(%)] of values obtained during normoxia (* indicates a statistically significant difference at p < 0.05).
