Serum prolactin levels and PTTG mRNA in prolactinomas in dopamine agonist responsive or resistant patients. A: Serum prolactin levels in responsive and resistant patients with prolactinomas after prolonged dopaminergic therapy (see Materials and Methods). N = 6 and 14, * P < 0.05. B: Comparative pituitary pttg mRNA content (evaluated by real time PCR) in patients with macroprolactinomas. N = 6 for Responsive patients (patients with normalization of prolactin levels after dopaminergic treatment), and N = 14 for patients resistant to such therapy.
