Figure S7. Anti-proliferative effects of curcumin, imatinib and curcumin+imatinib combination on CML cell viability. Curcumin and imatinib were tested for their anti-proliferative effects on K562 (a) and LAMA84 cells (b). The assays were performed by using curcumin and imatinib singly (using the reported doses) or in combination (20 μM curcumin held constant and imatinib at reported concentrations. In K562 cells combination compound treatments showed significant differences compared to single imatinib treatments for all doses tested (p < 0.001). In LAMA84 cells combination compound treatments showed significant differences compared to single imatinib treatments for lower doses tested (p < 0.001 at 0.1 and 0.2 μM), while no significant differences were observed between combination compound and imatinib at 0.5–5 μM because high cell death occurred. Combination Index (CI) analysis of growth inhibition in K562 (c) and LAMA84 cells (d) after 48 h incubation using curcumin (20 μM) and imatinib (different concentrations). Data from Fig. S6a and S6b were converted to Fraction Affected (FrAf) and plotted against Combination Index (CI). Results were as follows for imatinib concentration: ▲ = 0.1 μM; ♦ = 0.2 μM; ● = 0.5 μM; □ = 1 μM; ○ = 5 μM. Straight line on the graph designates a CI equal to 1. Combination Index interpretation was as follows: CI value of 1 indicates additivity; CI < 1 indicates synergism; and CI > 1 indicates antagonism. (PPTX 50 kb
Additional file 10: of SWATH-MS based quantitative proteomics analysis reveals that curcumin alters the metabolic enzyme profile of CML cells by affecting the activity of miR-22/IPO7/HIF-1α axis
Figure S5. Representative western blots and corresponding densitograms showing that in K562 (a) and LAMA84 cells (b) curcumin decreased nuclear levels of HIF-1α. Ponceau S of nuclear extract was used as loading control. Intensities of proteins band (in Ponceau S the band used is indicated with arrow) were calculated from the peak area of densitogram by using Image J software. Ctrl: control cells. (PPTX 809 kb

Figure S6. IPO7/miRNAs correlation. a Analysis performed by using microRNA target prediction software miRSearch V3.0 showed that IPO7 is a validated target of miR-22 and miR-9. b Analysis of predicted multiple targets performed by MicroRNA Target prediction (miRTar) tool ( http://mirtar.mbc.nctu.edu.tw/human/ ) revealed within the CurcuDown-Regulated dataset the presence of several of miR-22 targets beside IPO7. No target of miR-9 was found. (PPTX 179 kb

Validation of a Novel Shotgun Proteomic Workflow for the Discovery of Protein–Protein Interactions: Focus on ZNF521
The
study of protein–protein interactions is increasingly
relying on mass spectrometry (MS). The classical approach of separating
immunoprecipitated proteins by SDS-PAGE followed by in-gel digestion
is long and labor-intensive. Besides, it is difficult to integrate
it with most quantitative MS-based workflows, except for stable isotopic
labeling of amino acids in cell culture (SILAC). This work describes
a fast, flexible and quantitative workflow for the discovery of novel
protein–protein interactions. A cleavable cross-linker, dithiobisÂ[succinimidyl
propionate] (DSP), is utilized to stabilize protein complexes before
immunoprecipitation. Protein complex detachment from the antibody
is achieved by limited proteolysis. Finally, protein quantitation
is performed via <sup>18</sup>O labeling. The workflow has been optimized
concerning (i) DSP concentration and (ii) incubation times for limited
proteolysis, using the stem cell-associated transcription cofactor
ZNF521 as a model target. The interaction of ZNF521 with the core
components of the nuclear remodelling and histone deacetylase (NuRD)
complex, already reported in the literature, was confirmed. Additionally,
interactions with newly discovered molecular partners of potentially
relevant functional role, such as ZNF423, Spt16, Spt5, were discovered
and validated by Western blotting
