HeLa E2F1 ChIP-chip experiments


ABSTRACT: These are three biological replicates. HeLa cells were crosslinked on separate days. In each case, a matched total from the same crosslinking was produced in parallel. Amplicons were made from each and hybridized onto ENCODE region tiling arrays. Two color arrays were used; ChIP was red, Total was green. Goal was determination of E2F1 binding sites in HeLa cells by using ChIP-chip methodology. See Farnham Lab website for downloadable protocol for ChIP or supplementary file (Chip_protocol.txt) below. NimbleGen performed all array processing. See NimbleGen website for information on array procedures.

The E2F family of transcription factors regulates basic cellular processes. Here, we take an unbiased approach towards identifying E2F1 target genes by examining localization of E2F1-binding sites using high-density oligonucleotide tiling arrays. To begin, we developed a statistically-based methodology for analysis of ChIP-chip data obtained from arrays that represent 30 Mb of the human genome. Using this methodology, we identified regions bound by E2F1, MYC, and RNA Polymerase II (POLR2A). We f  ...[more]
