EFFECT OF HYPERGLYCEMIC-GLYCOGENOLYTIC FACTOR AND EPINEPHRINE ON LIVER PHOSPHORYLASE

Open access
Sutherland, Earl W., Cori, Carl F.·1951·Journal of Biological Chemistry

Abstract

The hyperglycemic-glycogenolytic (H-G) factor, a protein originating in the islet tissue of the pancreas (l-3), and various sympathomimetic amines, of which epinephrine is the chief representative, cause increased hepatic glycogenolysis in viva and in vitro. The glucose output of rabbit liver slices has been used as a quantitative test system for the action of these glycogenolytic agents in vitro. Since there are only three enzymatic reactions involved in the formation of blood sugar in the liver, there was some hope of finding out which of these was the primary point of action. It will be shown in this paper that the first step, the phosphorylase reaction, is rate-limiting and that the H-G factor and epinephrine exert their effect by causing a rapid increase in the phosphorylase activity of the liver.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
