total RNA from DMBA induced tumor
Total RNA was extracted by Trizol from whole tumors that were excised from each sample, followed by library preparation using Illumina's TruSeq RNA library kit andsequencing on an Illumina HiSeq2500 (Illumina, Inc., San Diego, CA). Individual libraries were preparedfor each sample, indexed for multiplexing, and then sequenced on an Illumina HiSeq2500
