Mapping of temporally-shifted regions in siPREP1 cells. Representative genomic region (17 Mb in length) from the UCSC Genome Browser showing (top to bottom): the S50 profile and S50 valleys of siLuc cells (light blue track and boxes, respectively); Temporal Transition Regions (TTR, black) and Late-Replicating Regions (LRR, green horizontal lines); LtoE-shifted regions identified in siPREP1 cells (red boxes); Lamin B1-bound DNA (deep blue signals corresponding to positive log2-ratio scores14); EtoL-shifted regions identified in siPREP1 cells (dark blue boxes); position of RefSeq genes, as indicated.
