Small RNA paper page

HEY! welcome to the short RNA paper page. This paper is being headed up by Helena Persson, Eiven Valen, Michiel de Hoon (?), Timo Lassmann (?), and Max Burroughs.

Brainstorming:

• novel miRNA prediction, tissue specific: Helena
• endo siRNA: Eiven/Helena?
• coding/noncoding overlapping short RNA and mechanistic implications?: Eiven
• cell-specific short RNA derived from known precursors: ?
• cell-specific novel short RNA populations. I suspect these two are quite related, "novel" populations will likely be derived from known precursors which are significantly differentially processed in certain cell lines. I think its better to look for the differential expression of all tags instead of looking specifically at known noncoding classes--max
• 'differential' post-transcriptional modifications: Max
• differential expression of tiRNAs and how this effects hCAGE expression across the panel

• one analysis we will need to do for the lncRNA paper is to overlay lnRNA-intersecting short RNA with to see if/how this influences the chains

Notes:

• I vote for RLE normalization. It performs slightly better than TMM or tpmm and its easy. see this page for details. I can play around and see if RLE performs better on all tags (with a cut-off) or on just miRNA loci. (Max)
• see if we can get some timecourses. this would give the paper another angle and Helena points out it would be useful to show important RNAs for wet-bench collaborators
• defining 'clusters' for promoter-based RNAs/endo-siRNAs other novel populations could be a bit tricky
• might be nice to do expression comparisons between short RNAs and hCAGE peaks, could be an additional form of validation for novel stuff
• Helena might be able to provide (limited) validation for novel miRNAs
