Gender-Specific Effects of Selection for Drinking in the Dark on the Network Roles of Coding and Noncoding RNAs

Background: Transcriptional differences between Heterogeneous stock (HS/NPT) mice and High Drinking in the Dark (HDID) selected mouse lines have previously been described based on microarray technology coupled with network based analysis (Iancu et al., 2013b). The network changes were reproducible in two independent selections and largely confined to two distinct network modules; in contrast differential expression appeared more specific to each selected line. The current study extends these results by utilizing RNA-Seq technology, allowing evaluation of the relationship between genetic risk and transcription of non-coding RNA; we additionally evaluate sex-specific transcriptional effects of selection.
