In contrast, these studies focus on a distinct set of small RNAs—the piwi‐interacting RNAs (piRNAs)—and their effector proteins such as MILI and MIWI2, which together safeguard genome integrity in the male germline by mediating sequence‐specific silencing of transposable elements through de novo DNA methylation and chromatin remodeling."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nAdditional investigations described in these abstracts delineate the mechanistic underpinnings of piRNA-directed transposon repression.
