Ab initio reconstruction of cell type-specific transcriptomes in mouse reveals the conserved multi-exonic structure of lincRNAs

High-throughput sequencing of total cellular RNA by RNA-Seq promises rapid reconstruction of spliced transcripts in a cell population. Guttman et al. accomplish this using only paired-end RNA-seq data and an unannotated genome sequence, and apply the method to better define many new, conserved long intergenic noncoding RNAs (lincRNAs).
