library_construction_protocol: RNA was isolated using RNA STAT 60 (Amsbio) as per the manufacturer's protocol. ~ 2000 ng of RNA was converted to complementary DNA using a High Capacity cDNA Reverse Transcription Kit (Applied Biosystems). RNA was submitted to UCLA's Technology Center for Genomics & Bioinformatics (TCGB) core for library preparation and 2x100 paired-end sequencing.
