Putative embryonic brain lncRNAs are related to imprinted genes and unspliced ESTs.

<p>(A) Shown are the proportions of putative lncRNAs and permutated lncRNAs within 100k distance of compiled imprinted genes. Putative embryonic brain lncRNAs are involved in imprinted regions, comparable with putative lncRNAs in ES cell. (B) Shown are the proportions of putative lncRNAs and permutated lncRNAs that overlap with unspliced ESTs. Putative lncRNAs are significantly overlapped with unspliced ESTs. Embryonic, lncRNAs expressed at embryonic stages; ES, lncRNAs expressed at the ES stage; Red bar, the proportion of lncRNAs; Box, the proportion of permutated lncRNAs; whiskers denote the 10th and 90th percentiles.
