HeLa cells were un-transfected or transfected with specific siRNAs (20µM) targeting IKAP/hELP1 or non-specific siRNAs against GFP. Same experiment was done by stimulating the cells for 1 hour with TNF-a (200U/ml). conditions: 1/untransfected 2/siRNAs IKAP 3/untransfected + TNF-a 200U/ml 1h 4/siRNAs ...
