After 72 h, the ablation of SCD1 protein was determined by western blot analysis. GAPDH was used as a loading control. ( B ) PA-1 and SKOV-3 cells were transfected with SCD1 siRNA (100 nM). At 72 h post-transfection, cell viability was analyzed using MTT assay.

( A ) PA-1 and SKOV-3 cells were treated with the IC50 value of CAY10566 for PA-1 cells (20 nM) for 48 h. Desaturase activity of SCD1 was estimated as the ratios of palmitoleic acid (C16:1n7) to palmitic acid (C16:0) and oleic acid (C18:1n9c) to stearic acid (C18:0) using gas chromatography. The statistical analysis was conducted using a two-way ANOVA followed by Šídák’s multiple comparisons test.

The percentage of apoptotic cells was determined by flow cytometry analysis using Annexin V-FITC and PI staining.
