a) A431 cells treated with hu3S193, hu3S193-9r(1), hu3S193-9r(1):siSTAT3(5:1) and hu3S193-9r(1):siLuci(5:1) and b) MDA-MB-435 cells were treated with hu3S193 and hu3S193-9r(1):siSTAT3(5:1) for 48 h and then analyzed using the MTS assay. The siRNA concentration was 300 nM.
*, **P-value between hu3S193-9r(1):siSTAT3(5:1) and hu3S193-9r(1):siLuci(5:1) treatment on A431 cell line with 10% serum is 0.0006*, with 2% serum is 0.008**.
