recently reported that chromatin immuno-precipitation followed by sequencing (ChIP-seq) reveals the genome-wide sites of occupancy by Piwi - a piRNA-guided Argonaute protein central to transposon silencing in Drosophila. Their study also reported that loss of Piwi causes widespread rewiring of transcriptional patterns as evidenced by changes in RNA polymerase II occupancy across the genome. Here we reanalyze their underlying deep sequencing data and report that the data do not support the author’s central conclusions.
