Here, we have assessed several steps in developing an optimized small RNA (sRNA) library preparation protocol for next. While every step in the cDNA library preparation is a potential source of bias, it is the nucleic acid ligases needed to add the sequencing adapters that have generated the most concern [ 5 , 7 , 10 , 13 , 25 ]. Since the first publications coining the term RNA-seq (RNA sequencing) appeared in 2008, the number of publications containing RNA-seq data has grown exponentially, hitting an all-time high of 2,808 publications in 2016 (PubMed). For this purpose the adapters oligonucleotides contain 4 randomized bases at the ligation junctions. In addition to mRNA transcripts, RNA-Seq can look at different populations of RNA to include total RNA, small RNA, such as miRNA, tRNA, and ribosomal profiling. miR-132 could modulate apoptosis via regulation of the.
