The effects of SDF or SDF-Se on mRNA expression. The NK cell mRNA levels were detected after exposure to different concentrations of SDF or SDF-Se (50, 100, and 200 μg/mL). Real-time PCR was used to detect the mRNA levels of (a) IFN-γ, (b) TNF-α, (c) NKp44, and (d) granzyme-B. β-Actin was used as normalization. Data are expressed as the mean ± SD. The asterisks indicate statistical changes (ns: not significant; , , and versus control group).
