Relationship between fetal arterial Po₂ and gluconeogenic factors after 9 days of study. A: plasma insulin to glucagon ratio in control (CON) and hypoxemia (HOX) fetuses. B: correlation analyses were performed to test the relationship of fetal arterial Po₂ and counter-regulatory hormone concentrations. C and D: correlation analyses were also performed for the relationship of fetal arterial Po₂ (C) and plasma cortisol (D) concentrations with glucose-6-phosphatase (G6PC) mRNA and phosphoenolpyruvate carboxykinase 1 (PCK1) mRNA expression. Data were log transformed, and individual data points are shown (n = 2 male and 5 female CON fetuses and 6 male and 5 female HOX fetuses).
