Combined rapamycin-octreotide treatment has a stronger antiproliferative effect on non-functioning pituitary tumor cells compared with each drug alone. The mechanism of the combined treatment action was studied in AtT-20 pituitary tumor cells. Rapamycin is known to induce cell cycle arrest at the G1/S transition point. The entry of eukaryotic cells into the cell cycle is controlled primarily by the activation of cyclin-dependent kinases (CDK4/CDK6 and CDK2) by their respective...
