Pre-miR miRNA precursors and siRNAs were purchased from Thermo Fisher Scientific, as follows: miR-124-3p (product ID: PM 10245), negative control miRNA (product ID: AM 17111), two ITGA3 siRNAs (product IDs: HSS105529 and HSS179967), two ITGB1 siRNAs (product IDs: HSS105559 and HSS105561), and negative control siRNA (product ID: D-001810-10). Lipofectamine RNAiMAX and Lipofectamine 2000 (Thermo Fisher Scientific) were used for transfection into PDAC cell lines. The transfection efficiencies of miRNA in cancer cells were calculated as described in previous studies [42 (link)].
