The top 20 RefSeq RNAs that are exclusively identified by Bowtie2 in A549 mRNA-seq dataset.

*PB: primer pair not available in whole transcriptome qPCR primer database. The primers are automatically designed using NCBI-PrimerBLAST. Please refer to Table S2 in File S1 for details.
**Identical to gene: two genes have identical sequence and thus are non-distinguishable by the mapping algorithm or RT-PCR.

*PB：引物对（primer pair）未收录于全转录组定量聚合酶链式反应（quantitative PCR, qPCR）引物数据库，本研究采用NCBI-PrimerBLAST工具自动设计所需引物，详细信息请参见File S1中的Table S2。
**基因序列一致：存在两个基因的序列完全相同，因此无法通过比对算法（mapping algorithm）或逆转录聚合酶链式反应（Reverse Transcription PCR, RT-PCR）对二者进行区分。
