I am searching for lncRNA expression differences within specific brain tissues (astrocytes vs neurons vs etc...) for humans. I have browsed numerous lncRNA databases (linked from https://en.wikipedia.org/wiki/List_of_long_non-coding_RNA_databases) and explored the ensembl regulatory build. That being said, I can''t find any comprehensive source that highlights that information.

Perhaps the only solution is to use publicly available RNA-seq data and perform the differential expression myself. But as I've never done that... and suspect others had this same question... I thought it would be prudent to post here.

Thus, I am hoping someone could either point me in the right direction or highlight what I should/shouldn't be doing. Perhaps there is a reason this information isn't readily available.

Thank you
