Double-stranded RNA-mediated silencing of genomic tandem repeats and transposable elements in the D. melanogaster germline

Abstract: Homology-dependent gene silencing was shown to be used to inhibit Stellate gene expression in the D. melanogaster germline, ensuring male fertility. dsRNA-mediated silencing may provide a basis for negative autogenous control of gene expression. The related surveillance system is implicated to control expression of retrotransposons in the germline.

“…aubergine is also responsible for acting post-transcriptionally to maintain silencing of the X-linked repetitive Stellate locus that is necessary for male fertility. The Stellate locus is silenced through a homology-dependent mechanism mediated by an RNA transcribed from paralogous repeats called suppressor of stellate, Su(Ste) (Aravin et al 2001). In wild-type males, an unprocessed and therefore untranslated 8-kb primary transcript is made from the Stellate locus.…”

“…Here we also discuss the evolution of the Y-linked Drosophila genes acquired from autosomes, the amplification of these sequences, and the visible degeneration of the Y, which has been followed by the acquisition of a novel function, the silencing of paralogous genes via RNA interference, mediated by double-stranded RNA production. (26) Evidence of Y chromosome degeneration The Y chromosome is considered largely inert and has been shown to have relatively little functional genetic content, concordant with ideas about the degeneration of the Y chromosome. (1,5) In particular, genes transposed to the nonrecombining region of the Y chromosome are susceptible to degeneration in their subsequent evolution.…”

“…(62) The molecular structures of Su(Ste) and Stellate repeats differ by the presence of hoppel transposon insertions in the intergenic regions of Su(Ste). (51) Hoppel insertions were shown to promote antisense Su(Ste) transcription (26) while their sense transcription was revealed earlier. (59) These findings suggested the involvement of the RNA interference (RNAi) mechanism in Stellate silencing by Su(Ste) repeats.…”

“…Contrôle post-transcriptionnel de l'expression des séquences répétées chez D. melanogaster L'expression des séquences Stellate (Ste), naturellement répétées dans le génome de D. melanogaster, semble régulée par un mécanisme semblable à l'ARNi [22,23]. Le locus Ste, localisé sur le chromosome X, est composé de la répétition en tandem d'un cadre ouvert de lecture dont le [34].…”
