Enhancer experiment: | Luciferase Reporter Assay,4C,PCR | |
Enhancer experiment description: | To test the predicted enhancers experimentally, we perfor-ed dual-luciferase reporter assays with constructs containing regions A, B, C or D, in direct or reverse orientation, upstream of the LMNB1 promoter . Following transfection of the constructs into HEK293T human cell line, regions A and B (in both orientations) significantly increased luciferase expression (A forward = 1.97 ± 0.2; A reverse = 1.8 ± 1.6; B forward = 2.52 ± 0.25; B reverse = 1.85 ± 0.10; mean ± standard error; P < 0.01; Fig. 3C). In contrast, constructs containing regions C and D did not significantly affect luciferase expression (Fig. 3C). Similar results were obtained when the same plasmids were transfected into NIH3T3 cell line (data not shown), suggesting that the enhancer activity of regions A and B could function across species, at least in mouse fibroblasts. Following these results, regions A and B were subsequently referred to as enhancer region A (Enh-A) and enhancer region B (Enh-B). To validate and better characterize Enh-A and -B interactions with the LMNB1 promoter, we performed nested-PCR on circularized DNA which confirmed that region A interacted in both patient and control, whereas the interaction of region B was patient-specific (SupplementaryMaterial). |
