Data are from one representative experiment out of 2 performed. (A) The Cell Proliferation Reagent WST-1 (Roche) was used to measure mitochondrial dehydrogenase activity of viable cells. Valinomycin was used as cell damaging control. Bars represent the mean +/2S.D. of 5 replicate wells. (B) The CellTiter-Glo Luminescent Cell Viability Assay (Promega) was used to estimate the number of viable metabolically active cells based on quantitation of ATP. Bars represent the mean +/2S.D. of 5 replicate wells. (C) The CytoTox-ONETM Homogenous Membrane Integrity Assay (Promega) was used for estimating the number of 16574785 dead cells by release of LDH from damaged cells.

Five biological replicates per treatment were reverse labelled by Cy3 and Cy5 and run together with the Cy2 labelled internal standard giving a total of 15 images. Using DeCyder Software analysis about 2500 spots were detected in each gel and quantified, normalized and inter-gel-matched.. Protein expression changes were considered as significant when their quantity decreased or increased by at least 1.3-fold (student’s T-test, p#0.05). Notably, Cry1Ab treatment caused only few modifications in protein expression Licochalcone-A profiles, only three proteins out of .2000 were differentially expressed (Table 1), one protein (heat-shock protein 70) was more abundant and two proteins (cytokeratin 8 and heterogeneous nuclear ribonucleoprotein) were less abundant.
