| In Vitro | Pimasertib (5, 0.5, and 0.1 μM) specifically blocks ERK1/2 activation in MM cells, cultured alone or with BMSCs. Pimasertib inhibits the growth of MM cell lines in a dose-dependent manner, with IC50s ranging from 0.005 to 2 μM. The IC50s of Pimasertib against INA-6, U266, H929 cells are 10 nM, 5 nM, 200 nM respectively. Pimasertib induces apoptosis and modulates the cell cycle profile. Pimasertib targets MM cells in the BM microenvironment[1]. Pimasertib (10 μmol/L) inhibits ERK pathway, proliferation, and transformation in cetuximab-resistant D-MUT cells[2]. Pimasertib in combination with PLX4032 significantly induces apoptosis of RPMI-7951 cells, whereas each drug used alone does not. Pimasertib synergizes with small interfering RNA-mediated downregulation of BRAF to produce results similar to those of combined treatment with PLX4032 and Pimasertib[3]. |
| In Vivo | Pimasertib (15, 30 mg/kg) significantly inhibits the growth of tumor in the human H929 MM xenograft model in CB17 SCID mice[1]. Pimasertib (10 mg/kg, p.o.) inhibits tumor growth of cetuximab-resistant tumor attributed by K-ras mutation[2]. |
| Cell Assay | The inhibitory effects of study compounds on MM cell growth and survival are assessed by both [3H]thymidine incorporation and by measuring MTT dye absorbance. Cells (104/well for MM cell line, in triplicates and 2-5×105/well for patient MM cells) are cultured in 96-well plates for 3 days (MM cell lines) or 5-days (patient MM cells). For the [3H]thymidine incorporation assay, cells are pulsed with 0.5 μCi (0.0185 MBq)/well [3H]thymidine for 6 h (cell lines), harvested onto glass fiber filters, and counted in a β-scintillation counter. Due to low DNA synthesis of patient MM cells, they are pulsed with 2 μCi/well [3H]thymidine and measured during the last 36 h of culture. |
| Animal Admin | CB17 severe combined immunodeficiency (SCID) mice are subcutaneously inoculated with H929 (4×106) cells in 100 μL RPMI-1640 medium. Mice developed palpable tumors (appr 130 mm3) approximately 3 weeks after cell injection and are randomized to receive orally twice daily either Pimasertib (15 or 30 mg/kg) or control vehicle alone. Tumor size is measured every other day in 2 dimensions using calipers, and tumor volume is calculated. Animals are euthanized when their tumors reach 2 cm3 in volume, when they are moribund or show paralysis or major compromise in their quality of life occurs. Tumor formation changes in mice treated with control vehicle vs. Pimasertib are plotted using the GraphPad Prism version 4.03 for Windows. Tumors are subjected to immunoblotting and immunochemistry analyses using specific monoclonal (m)Abs. Images are examined with a Leica DM LB research microscope, captured using Leica IM50 Image Manager, and processed using Adobe Photoshop Software version 7.0. |
