we have investigated the structure of dopamine ( da ) d2 receptors present in an estrone-induced , prolactin ( prl ) -secreting , da-sensitive adenoma and in two prl-secreting and da-insensitive transplantable tumors 7315a and mttw15 , in order to identify better the anomalies present in da-resistant lactotrophs .
