Figure 2From: TGFBI expression is associated with a better response to chemotherapy in NSCLCChanges in TGFBI expression affects cell viability. Cell viability of transfected NSCLC cells was determined by neutral red staining 24, 48 and 72 h after transfection with a TGFBI siRNA plasmid or a TGFBI expression vector. Transfection with empty vector was used as a negative control for all experiments. Three independent experiments were performed. Statistical comparisons of the differences between control and transfected cells were performed using Student t-test (* p < 0.05; **p < 0.01).Back to article page
