A Annexin V staining of MDA-MB-231 cells using flow cytometry to investigate apoptosis of MDA-MB-231 cells transfected with negative control (nc) siRNA, or siRNA directed against TLR2 mRNA (si#1 and si#2) or TLR4 mRNA (si#1 and si#2). TLR2 (si#1 and #2) gave contradicting results while TLR4 si#1 and #2 gave no effect (n = 3). Error bars indicate standard error of the mean (SEM); *P
