An integrative ChIP-seq analysis of regulatory regions

pc3

Name : PC-3 cell - BTO:0001061
Description : Human prostate carcinoma cell line; established from the bone marrow metastasis isolated post-mortem from a 62-year-old Caucasian man with grade IV prostate cancer, poorly differentiated adenocarcinoma, after androgen suppression therapy; described to form tumors in nude mice, to grow in soft agar, and to be unresponsive to androgen treatment.


To address ChIP-seq variability in term of quality, we used four different metrics based on ENCODE ChIP-seq guidelines to retain high quality datasets for downstream analyses. First we used the normalized strand cross-correlation coefficient (NSC) which is a normalized ratio between the fragment-length cross-correlation peak and the background cross-correlation, and the relative strand cross-correlation coefficient (RSC), a ratio between the fragment-length peak and the read-length peak to exclude low quality datasets. We also used the fraction of reads in peaks (FRiP) and the number of peaks identified in each dataset to filter datasets.
