Fig. 2From: Association between MEG3/miR-181b polymorphisms and risk of ischemic strokeEffect of the rs322931 on transcriptional activity. The fragment containing the rs322931 C or rs322931 T allele was transfected into HEK293 cells. pGL3-SV40 was used as an internal control and relative luciferase activity was measured 48 h post-transfection. Data are expressed as mean ± standard error (** P <  0.01)Back to article page
