Fifty nM siRNA was used to silence S100PBP in cells (Panc1 and MIA PaCa2). Briefly, 0.5 × 106 cells were seeded in tissue culture dishes before treatment with either scram (non-target) or two independent siRNA molecules against human S100PBP (Mol1: AUGGUGGUUCACACAAG UCAA, Mol2: CUGUGUGAGUAAUGCAUUCUA; Qiagen, UK) mixed with RNAiMax transfection reagent (Life Technologies, UK). Fresh medium was replaced after 16 h, and cells were harvested for protein and RNA analysis after 72 h of transfection. A fraction of cells from matching population were cultured on glass coverslips in their respective medium for cellular localisation studies.
