Table 1.
The relative expression levels of piRNAs that correspond to the type Gf Line-1 (A) and IAP (B) are shown. Relative expression is calculated from the microarray data and is shown as the ratio of the expression level of an individual piRNA in the MILI- and MIWI2-null mice to that in control mice. The numbers of piRNAs included in the relative expression range are described in the table.
