Are there any publicly available databases singularly providing expression data for any given long non-coding RNA (lncRNA) for
- varying cell types
- any species
- preferably including humans?
Alternatively, are there lesser known UCSC tracks for this, here?
For example, perhaps I want to find tissue-specific expression of human lncRNA Xist in HeLa, GM12878, and HEK293 cell types [or more].
