INA-6 MM cells were treated with AS703026 or AZD6244 for 2 d, followed by [3H]thymidine uptake assay. PBMCs isolated from normal donors (n = 3) were incubated with M-CSF and RANKL, in the presence or absence of AS703026 or AZD6244 for 14 d. The TRAP assay was performed to measure the formation of multinuclear osteoclast cells (OC).

AZD6244 enhanced FOXO3a expression and induced suppression of cancer cell proliferation. A, tumor volume of the HCT116 xenografts treated with Placebo or AZD6244 was measured for 21 d. The tumor sections of four individual DMSO or AZD6244-treated HCT116 xenografts were subjected to immunohistochemistry with a FOXO3a antibody. Relative percentages of nuclear FOXO3a expression of individual xenograft tumors from B were analyzed and the mean values of FOXO3a expression in Placebo or AZD6244-treated group were indicated as bars.

lysates from various cancer cell lines: breast cancer (MDA-MB-435), colon cancer (HCT116, SW620, and HT29), and melanoma (WM793) treated with DMSO or AZD6244 (10 μmol/L) for 4 h were subjected to immunoblotting with the indicated antibodies.

B-RafV600E mutated melanoma line,A375, was treated with different doses of AZD6244 for 1hour or 24 hours.Cell lysates were analyzed by Western Blotting to determine the levels of phosphorylated ERK1/2(Perk1/2)

A,ERK phosphorylation in A375 expressing indicated ORFs following treatment with DMSO or 1 mM of PLX4720, RAF265, CI-1040 or AZD6244. B,ERK phosphorylation in A375 expressing indicated ORFs following treatment with DMSO, PLX4720 (1 mM) or PLX4720 in combination with CI-1040 or AZD6244 (all 1 mM).

Ex vivo and functional characterization of MEK1(P124L). (A) AZD6244-mediated growth inhibition ex vivo of treatment-naïve BRAFV600E melanoma cells (black and blue) or cells cultured from an AZD6244-resistant metastatic focus (red). (B) ERK phosphorylation (p-ERK) andMEKphosphorylation (p-MEK) are shown following treatment with increasing concentrations of AZD6244 in treatment-naïve or AZD6244-resistant melanoma cells cultured ex vivo. The tubulin loading control (-tubulin) is also shown. (C) AZD6244 growth inhibition curves of parental A375 (solid black), A375 cells expressing MEK-DD (grey), wild-type MEK1 (hatched black), or MEK1(P124L) (red) are shown. In each instance n6 anderrorstandard deviation. (D) p-ERK and p-MEK are shown following treatment with increasing AZD6244 concentrations in the cell lines described in C, Above. The -tubulin control is also shown.

A and B, clonogenic assays in 2 melanoma cell lines (YUVON and YUSIK) treated with NVPBEZ235 (BEZ) and AZD6244 (AZD) alone and in combination. Combinations were more effective in inhibiting colony formation at lower concentrations than either drug alone.

Survival curves for isogenic cell line pairs and melanoma cultures treated with the indicated AZD6244 concentration for 72 h (relative to DMSO treated controls; mean6s.e.m., n55). PLX4032 resistant cells were grown with PLX4032. Dashed line, 50% cell killing.
