Description

This track is produced as part of the ENCODE Transcriptome Project. Transcription of different RNA extracts from different sub-cellular localizations in different cell lines is compared in companion experiments using three different technologies: tiling arrays, RNA-seq using Solexa, and RNA-seq using SOLiD. The tiling array data are shown in this track. The Raw Signal view shows an estimate of abundance of RNA molecules and the Transfrags view shows the locations of sites corresponding to these molecules.

Display Conventions and Configuration

To show only selected subtracks, uncheck the boxes next to the tracks that you wish to hide.

Color differences among the views are arbitrary. They provide a visual cue for distinguishing between the different cell types and compartments.

Transfrags
The Transfrags view includes all transfrags before filtering.
Filtered Transfrags
The Filtered Transfrags view excludes repeats and other known annotations including: tRNAs and rRNAs, mi/snoRNAs, things mapping to the mitochondrial or Y chromosomes, and many predicted snoRNAs and miRNAs.
Raw Signal
The Raw Signal view shows the probe intensity based on all probes.
Filtered Signal
The Filtered Signal view shows the probe intensity based on the filtered set of probes.
Regions with negative signal value are areas where the mismatch probe hybridizes better than the match probe. This could indicate presence of a SNP, a site of RNA editing, or sequencing error.

Methods

Cells were grown according to the approved ENCODE cell culture protocols. RNA molecules longer than 200 nt and present in RNA population isolated from different subcellular compartments (such as cytosol, nucleus, polysomes and others) were fractionated into polyA+ and polyA- fractions as described in these protocols. Each RNA fraction was converted into double-stranded cDNA using random hexamers, labeled and hybridized to a tiling 91-array set containing probes against the non-repetitive portion of the human genome tiled on average every 5 bp (center-to-center of each consecutive 25-mers).

All arrays were scaled to a median array intensity of 330. Within a sliding 61 bp window centered on each probe, an estimate of RNA abundance (signal; see the Raw Signal view) was found by calculating the median of all pairwise average PM-MM values, where PM is a perfect match and MM is a mismatch. Kapranov et al. (2002), Cheng et al. (2005) , Kapranov et al. (2007), and Cawley et al. (2004) are good references for the experimental methods. Cawley et al. also describes the analytical methods.

Verification

The reproducibility of the labeling method was assessed separately. Three independent technical replicates were generated from the same RNA pool for each RNA preparation and hybridized to duplicate arrays (two technical replicates) that contain the ENCODE regions. Labeled RNA samples were then pooled and hybridized to the tiling 91-array set spanning the whole genome. Transcribed regions (transfrags; see the Transfrags view) were generated from the Raw Signal by merging genomic positions to which probes are mapped. This merging was based on a 5% false positive rate cutoff in negative bacterial controls, a maximum gap (MaxGap) of 40 base-pairs and minimum run (MinRun) of 40 base-pairs.
