The effect of neurotensin on the plasma cholesterol levels in the rat.
The effect of the hypothalamic tridecapeptide neurotensin (NT) on the plasma cholesterol levels was studied in the rat. 15 min after the intravenous administration of 1.25 pmol/100 g body weight NT, the concentration of the total plasma cholesterol was increased about 25% above the control values (P less than 0.001) and remained at about the same level 30 min after the injection. The hypercholesterolemic response to the intravenous administration of NT increased dose dependently (12.5 and 125 pmol). Adrenalectomy and hypophysectomy did not modify the hypercholesterolemic effect of NT. The data suggest that NT may have a role in cholesterol transport.
