Lack of effect of cortisone,thyroxine and insulin on the developmental pattern of mouse intestinal glucose-6-phosphatase activity

Summary Daily administration for 3 days of cortisone (25 g/g b.wt), thyroxine (1 g/g b.wt) or insulin (12.5 mU/g b.wt) to 8-day-old suckling mice does not induce a premature decrease of the phosphohydrolase activity of intestinal glucose-6-phosphatase.Supported by grant MA-5969 from the Medical Research Council of Canada (D.M.).
