WebThe overlap between the ChIP-Seq and RNA-seq datasets, generated in the SUM159 cells, identified a short list of 57 genes directly bound and regulated by E4F1 in these cells (Figure 2D,E). As previously observed in the murine cells [ 17 ], a majority of these human genes were downregulated in E4F1-depleted SUM159 cells, suggesting that E4F1 ...

Objectives of this tutorial After completing this vignette, you will be able to: 1. Read a ChIP-seq experiment into R 2. Extend the reads and bin the data (details and relevance discussed later) 3. Generate .bedGraph files 4.
WebFinally, we want to gain some experience comparing ChIP-seq experiments. At first pass it might make sense to make a Venn diagram comparing peaks from two experiments to see how many overlap. This is a horrible way to analyze ChIP-seq data!!! This is because many peaks are close to the threshold of detection, barely making the cut for ...
