Analysis of weight gain under normoxic and hypoxic conditions. Percent body weight gain (% BW gain) was determined for Hif1a+/+ (open bars) and Hif1a+/– (closed bars) mice exposed to 21% O for 6 weeks (n = 10) or 10% O for 1–6 weeks (n = 54–57), using the following formula: % BW gain = ([BWfinal – BWinitial] / BWinitial) × 100. *P = 0.02; #P = NS (Student's t test).
