RT Journal Article SR Electronic T1 Effect of Varying the Insulin to Glucagon Ratio on Porphyrin Biosynthesis in Chick Embryo Liver Cells JF Molecular Pharmacology JO Mol Pharmacol FD American Society for Pharmacology and Experimental Therapeutics SP 717 OP 721 VO 14 IS 4 A1 PETER W. F. FISCHER A1 JANET K. STEPHENS A1 G. S. MARKS YR 1978 UL http://molpharm.aspetjournals.org/content/14/4/717.abstract AB Allylisopropylacetamide-induced porphyrin accumulation in chick embryo liver cells depends upon the insulin to glucagon ratio. A low level of porphyrin accumulation occurs at insulin to glucagon ratios similar to those found following glucose administration in vivo, suggesting a possible explanation for the therapeutic effect of glucose in hepatic porphyria.
