mRNA was purified from total RNA using poly-T magnetic beads. Purified mRNA was fragmented into 400500 bp, reverse-transcribed into cDNA, and converted to blunt-ended fragments with20 adenylation. Illumina PE adapters were ligated, followed by size sele_x0004__x001f__x001f__x0003__x0004_  _x0003__x0004_!!_x0003__x0004_""_x0003__x0004_##_x0003__x0004_$$_x0003__x0004_%%_x0003__x0004_&&_x0003__x0004_''_x0003__x0004__x0011__x0011__x0008__x0008__x0011__x0011_ _x000c__x0012__x0012__x0005__x0008__x0012__x0012_ _x000c__x0013__x0013__x0005__x0008__x0013__x0013_ _x000c__x0014__x0014__x0005__x0008__x0014__x0014_ _x000c__x0015__x0015__x0005__x0008__x0015_(  _x0016_(_x0005__x0008__x0016_(_x0005__x0008__x0016_(
