WebSep 1, 2024 · This paper reviews the advances in piRNA studies and provides a complete description of piRNA biogenesis, function, and clinical implications in cancer. Under normal conditions, piRNAs are synthesized and degraded in germ cells and somatic cells at relatively stable levels. However, when the piRNA expression is disrupted, they lose … WebpiRNA Biogenesis Germline-specific piRNAs and Piwi proteins play a critical role in genome defense against transposable elements, thereby protecting the genome against transposon-induced defects in gametogenesis and fertility.
