+ARTICLE = '''
+Insulin sensitivity and liver insulin receptor structure in ducks from two
+genera
+
+T. Constans, B. Chevalier, M. Derouet and J. Simon
+Station de Recherches Avicoles, Institut National de la Recherche Agronomique,
+Nouzilly, France.
+
+Insulin sensitivity and liver insulin receptor structure were studied in
+5-wk-old ducks from two genera (Muscovy and Pekin). In the fasting state, both
+duck types were equally resistant to exogenous insulin compared with chicken.
+Despite the low potency of duck insulin, the number of insulin receptors was
+lower in Muscovy duck and similar in Pekin duck and chicken liver membranes.
+After 125I-insulin cross-linking, the size of the alpha-subunit of the
+receptors from the three species was 135,000. Wheat germ agglutinin-purified
+receptors from the three species were contaminated by an active and unusual
+adenosinetriphosphatase (ATPase) contaminant (highest activity in Muscovy
+duck). Sequential purification of solubilized receptor from both duck types on
+lentil and then wheat germ agglutinin lectins led to a fraction of receptors
+very poor in ATPase activity that exhibited a beta-subunit size (95,000) and
+tyrosine kinase activity similar to those of ATPase-free chicken insulin
+receptors. Therefore the ducks from the two genera exhibit an alpha-beta-
+structure for liver insulin receptors and a clear difference in the number of
+liver insulin receptors. Their sensitivity to insulin is, however, similarly
+decreased compared with chicken.
