Dissection of lncRNA Lx8-SINE B2 promoter region. (a) Schematic of the positions of TEs on according to mouse mm10 genome the promoter region of lncRNA Lx8-SINE B2. (b) Schematic of various length fragments of lncRNA Lx8-SINE B2 promoter constructs. (c) Activities of various length fragments of lncRNA Lx8-SINE B2 promoter constructs were determined by luciferase reporter gene assays in E14 ESCs. Biological-triplicate data (n = 3 dishes) are presented as mean ± s.e.m. (d) Luciferase assay analysis of core promoter activity of lncRNA Lx8-SINE B2 in ESCs and 3T3 cells. Biological-triplicate data (n =3 extracts) are presented as mean ± s.e.m.
