Knock down of the IR enhanced SS1P toxicity in several cell lines. A431/H9 (A), KB31 (B), A1847 (C), M30 (D) A431(E) and HAL-01(F) cells were transfected with siIR-1 (siIR) or control siRNA GL2 (siCO) for 48 hours in 96 well plates. SS1P was then added for 72 hours. Cell viability was measured by an ATP assay.
