Abstract: Piwi-interacting RNAs (piRNAs) are a class of small non-coding RNAs that associate with PIWI subfamily proteins, which play an important role in transposon silencing in animal germ cell. The piRNAs biogenesis is divided into two… read more here.

DOI: 10.1038/s41556-021-00746-2
Abstract: PIWI-interacting RNAs (piRNAs) support the germline by suppressing retrotransposons. Studies of the pathway in mice have strongly shaped the view that mammalian piRNAs are essential for male but not for female fertility. Here, we report… read more here.

DOI: 10.1093/nar/gky761
Abstract: Abstract Transposable elements (TEs) are parasitic DNA sequences that threaten genome integrity by replicative transposition in host gonads. The Piwi-interacting RNAs (piRNAs) pathway is assumed to maintain Drosophila genome homeostasis by downregulating transcriptional and post-transcriptional… read more here.

DOI: 10.1111/1744-7917.13096
Abstract: As a defense mechanism against transposable elements, the PIWI‐interacting RNA (piRNA) pathway maintains genomic integrity and ensures proper gametogenesis in gonads. Numerous factors are orchestrated to ensure normal operation of the piRNA pathway. Spindle‐E (Spn‐E)… read more here.

DOI: 10.1111/1744-7917.13160
Abstract: The Piwi-interacting RNA (piRNA) pathway has been shown to be involved in the antiviral defense against RNA viruses, especially in mosquitoes, but its universality has been questioned. Here, we used the Bombyx mori nucleopolyhedrovirus (BmNPV)-infected… read more here.

DOI: 10.1126/sciadv.abn1441
Abstract: Across Metazoa, Piwi proteins play a critical role in protecting the germline genome through piRNA-mediated repression of transposable elements. In vertebrates, activity of Piwi proteins and the piRNA pathway was thought to be gonad specific.… read more here.

Abstract: In metazoan germlines, the piRNA pathway acts as a genomic immune system, employing small RNA-mediated silencing to defend host DNA from the harmful effects of transposable elements (TEs). Expression of genomic TEs is proposed to… read more here.

DOI: 10.3389/fgene.2020.610665
Abstract: One of the main conditions of the species splitting from a common precursor lineage is the prevention of a gene flow between diverging populations. The study of Drosophila interspecific hybrids allows to reconstruct the speciation… read more here.
