Figure 2. Size distribution and annotation of small RNAs from the libraries of LNCaP and LNCaP-AI.

(A) Length distribution of sequenced reads. Both libraries accumulated 22-nucleotide small RNAs, which is consistent with the typical size of miRNAs. B) The proportions of various classes of small RNAs detected in LNCaP and LNCaP-AI. It is indicated that the majority of reads in both libraries belonging to the miRNA families.
