[Fatty tissue insulin receptors in patients with an elevated level of contrainsulin hormones with and without concomitant diabetes mellitus].
An equally lowered insulin specific binding in the fatty cell plasmic membranes was found in patients with glucocorticoid, somatotropin and catecholamine hyperproduction during diabetes mellitus and/or its absence. This fall is due exclusively to a reduced amount of binding sites in patients with hypercorticism and acromegaly, accompanied or not by diabetes, and in persons with diabetes-aggravated pheochromocytoma. The above decrease is caused by a lowered binding site number and augmented negative cooperativity in patients suffering from pheochromocytoma without diabetes. The results obtained allow a conclusion that inhibited expression of insulin receptors in the presence of counter-insulin hormone hyperproduction promotes diabetes arising.
