We treated all of drugs in T47D which has a PI3KCA H1044R mutation with the concentration shown below for 1 hour and performed western blot analysis using antibodies to phospho-AKT(SERINE 472), and total AKT.

The enhanced level of histone methylation by HDAC inhibitors parallels the increase of acetylation of histone 3.In both MDA-MB-231 and MDA-MB-468 cell lines, exposure to LBH589 and other compounds produced significant global increase of nuclear H3K4me2, which is the specific substrate of LSD1.

Secondary assay development. The invasive potential of MDA-MB-231 spheroids was measured using modified Boyden chambers coated with Matrigel™. Invading cells were fixed, stained with DAPI, and quantified by fluorescence microscopy using 5 random fields per filter insert in triplicate. U0126, PF2341066, axitinib, and PKC412 inhibited the invasive potential of MDA-MB-231 spheroids by ~90% as compared to untreated spheroids (UT). ***p ≤ 0.001. IGF1R and dasatinib displayed no statistical difference as compared to UT MDA-MB-231 spheroids.

Inhibition of anchorage-independent growth of lung tumor cell lines by selected inhibitors. Each selected cell line was treated with the indicated inhibitor at 0.1 μM and 1 μM concentrations for two weeks and cell colony size formation was scored under the Nikon inverted-phase microscope.

Ba/F3 cell lines expressing the recombinant TEL/kinase domain fusion protein for FGFR1-4 .Cells were grown in RPMI 1640 containing 10% FBS and 500 ng/mL puromycin. The parental Ba/F3 cell line transduced with an empty vector was grown in 10 ng/mL IL-3 (R & D systems). Cell viability was assessed at 72 hours using the Cell Titer 96 Aqueous One Solution (Promega). Data were plotted as percent viability relative to vehicle-treated cells and are shown as mean (± SD) from 3 experiments.
