4、 Furthermore, AMG 487 inhibits calcium mobilization in response toITAC (IC50=5 nM) 1. AMG487 (1 M) develops into fewer lung metastases, and the lungs are significantlysmaller than vehicle-treated lungs 2. AMG487 abrogates proliferation/survival of C26 tumour cells 3.体内研究 AMG 487 (0.03-10 mg/kg, s.c.

AMG487 reduces the tumour volume 3.PROTOCOLKinase Assay 3 Cells are then lysed and sonicated in 50 mM Hepes pH 7.5, 150 mM NaCl, 20 mM EDTA, 1 mM PMSF, 10 g/mL leupeptin, 2 g/mL aprotinin and 0.2% NP-40. Equal amount of lysates are mixed in substrate buffer(50 mM Hepes, 100 mM NaCl, 1 mM

Tumor diameters are measuredby caliper twice weekly, and mice are euthanized on an individual basis when the s.c. tumor measured 18mm in diameter or earlier if the mouse seemed moribund. The lungs

The lungs are removedand weighed, and surface tumor colonies are quantified in a blinded fashion under a dissecting microscope.A 50% hydroxypropyl-cyclodextrin solution is prepared; at 20%, this solution serves as the vehicle.AMG487 is added to the 50% solut

14、ion, and it is incubated in a sonicating water bath for 2 hours withoccasional vortexing. Distilled water is added to give the appropriate final concentration of AMG487 in 20% ofhydroxypropyl-cyclodextrin.MCE has not independently confirmed the accuracy of these methods. They are for reference only.
