Cytotoxicity by Dasatinib and Nutlin-3 used alone or in combination in B-CLL patient leukemic cells. B-CLL patient leukemic cells were exposed to serial doses of Dasatinib or Nutlin- 3 used either alone or in combination, with a fixed ratio, for 48 hours. Dose-effect plots, to determine drug efficacy, are shown for representative B-CLL samples, including 3 patients carrying 17p- (Pt. #7, Pt. #8, and Pt. #10). The decrease of cell viability, labeled "effect" on the Y-axis, was determined in assays done at least twice in duplicate.

Dasatinib interferes with the p53 transcriptional activity induced by Nutlin-3. Leukemic cell lines were exposed for 24 hours to Dasatinib (10 μM) and Nutlin-3 (10 μM), used either alone or in combination, as indicated. Levels of p53 (A), MDM2 and p21 (B) were assessed by Western blot analysis of total cell lysates. Representative examples of Western blot results are shown. Tubulin staining is shown as loading control; after densitometric analyses, p53 as well as MDM2 and p21 protein levels are expressed as folds of protein modulation, by the indicated treatments, with respect to the control untreated cultures set to 1 (hatched line). *P < 0.05 with respect to the Nutlin-3-treated cultures.

Role of Akt in Dasatinib cytotoxicity and in DasatinibtNutlin-3 synergy. A, whole cell lysates were prepared from EHEB and BJAB cell lines treated (for 16 hours) as indicated, and hybridized with a human Phospho-Kinase array kit. Spot densities of phospho-proteins were quantified using Image Quant TL software and normalized to those of positive controls (set at 100) on the same membrane. The analysis of modulation of phosphorylation signals for P-ERK1/2, P-p38, and P-Akt are reported (*P < 0.05). Validation of phospho-kinase array results was carried out by Western blot analysis of P-Akt levels.

Impact of the TKI erlotinib, lapatinib, dasatinib, and sorafenib on the viability of MDS/AML cells. MOLM-13 (A) and HL-60 (B) cells were incubated with the indicated doses (given in mM below the x-axis) of the 4 TKI, and cellular viability was assessed by MTT assay after 24, 48 and 72 h of incubation. Changes in viability are given as percentage of cells as compared to non-treated control samples. This experiment was repeated at least three times, yielding comparable results. Graphs show representative results of one experiment carried out in duplicates (mean standard deviation).

Human phospho-kinase array analysis in response to Dasatinib treatment. Whole cell lysates were prepared from EHEB (p53wt) and BJAB (p53mut) B cell lines, either left untreated or exposed to Dasatinib for 24 h, and hybridized with a human Phospho-Kinase array kit. Spot densities of phospho-proteins were quantified using Image Quant TL software and normalized to those of positive controls on the same membrane. In a, intense decreases of signal of P-p38, PERK1/2 and P-CREB in response to Dasatinib are indicated by arrows in the membranes, and intensity of corresponding spots are reported as graphics. In b, analysis of modulation of phosphorylation of STAT family members in response to Dasatinib (spots not shown). The means±SD of three independent experiments are shown. Asterisk indicates P<0.05 against untreated.

Cells were either left untreated (Unt.) or exposed to Dasatinib (Das.) for 24 h. Equal amounts of cell lysates were analyzed for ERK1/2, p38 and CREB phosphorylation by Western blot using antibodies specific for the native form of the kinases and for residues that are phosphorylated (P-) in each kinase upon activation. One of three experimentswith similar results is shown. Protein bands were quantified by densitometry and level of PERK1/2, P-p38 and P-CREB expressed as arbitrary units,were calculated for each cell line after normalization to total ERK1/2, p38 and CREB respectively

Inhibition of cell growth upon culturing of primary bone marrow cells from an EMS patient and a healthy control in presence of TKIs in vitro. EMS cells showed reduced cell growth compared to the healthy control cells when cultured with ponatinib, dovitinb or dasatinib. Cell growth was evaluated after 72 hours in culture. All samples were normalized to DMSO controls. Non-linear regression curves were fitted for evaluation of IC50 values. Error bars represent mean values and standard deviation of the analyzed replicates.
