Effect of AgNPs on mRNA expression level of apoptotic markers in cancer cells. Cells were treated with different concentration of AgNPs for 24 h. Nanostructure-induced alterations in mRNA expression levels are expressed as fold change in relative quantity with those of control cells. CT values for other genes were calculated in reference to GAPDH control. (A) Breast cancer cells (MCF-7) were treated with 5 µg/mL and 10 µg/mL silver nanoparticles, while (B) HCT-116 cells were incubated with 10 and 20 µg/mL for 24 h.
