With PolII occupancy in mESCs also as in totally differentiated
With PolII occupancy in mESCs at the same time as in fully differentiated adipocytes. Our findings indicate that 5hmC has a repressive role at distinct distal regulatory regions and recommend that 5hmC is a new epigenetic mark for silenced enhancers. MethodsExperimental croceduresdNTPs and the PCR solutions ligated in to the pGL3-SV40 luciferase vector (Promega). Empty vector (control) or cloned vectors had been transfected directly into R1 mESC, collectively together with the pRL-tk vector (Promega) as internal handle, working with Lipofectamine LTX (Life Technologies). At 24 h just after transfection, cells had been harvested and lysates subjected for the dual-luciferase reporter assay (Promega). Firefly luciferase activity was measured and normalized for the internal control, Renilla luciferase activity.Added fileAdditional file 1: Figure S1. 5hmC profile at promoters and enhancers.
