In order to study the 3D DNA structures which regulate contacts between cis-regulatory elements (CREs) and their target transcribed elements (TEs), we are developing a super-resolution imaging approaches capable of resolving tens to hundreds of individual CREs, TEs, and intervening sequence in single cells of sectioned embryonic tissue and cultured cells at better than 20 nm resolution. We are applying this approach … Continue reading Visualizing cis-interactions in vivo
