Cloning and expression profiling of testis-expressed microRNAs

Abstract: Using a new small RNA cloning method, we identified 141 miRNAs from the mouse testis, of which 29 were novel. The 141 miRNAs were mapped onto all chromosomes except the Y chromosome and 2/3 of these miRNA genes exist as clusters. approximately 70% of these miRNA genes were located in intronic or intergenic regions, whereas the remaining miRNAs were derived from exonic sequences. We further validated these cloned miRNAs by examining their expression in multiple mouse organs including developing testes and also … Show more

“…The roles of miRNAs in mammalian testis and spermatogenesis have been identified by the facts that a number of miRNAs are expressed preferentially in male germ cells (Ro et al 2007) and a suite of novel miRNAs are expressed in spermatozoa [35].…”

“…MiRNAs are short (∼22 nt in length) non-coding RNA molecules that bind specifically to mRNA molecules to posttranscriptional control of gene expression [52]. They regulate multiple intracellular processes, such as differentiation, growth, apoptosis [40,42] and the response to cellular stress. Alterations in miRNAs expression may occur following exposure to stress-generating agents.…”

“…Prediction of microRNA targets in 39 UTRs was based on context scoring (Grimson et al 2007) performed with TargetScanMouse 5.0. We identified the most abundant microRNAs in various mouse tissues via a public microRNA expression database (Betel et al 2008) or literature (Sood et al 2006;Ro et al 2007). Overrepresentation of repressed genes in the target list was assessed with the hypergeometric test.…”

“…Jusqu'à présent, le nombre de miARN identifiés dans le testicule est évalué à 141. Parmi ceux-ci, 35 % sont préférentiellement exprimés dans le testicule tandis que 5 % y sont exclusivement présents [10]. Récemment, le décryptage de l'ensemble des miARN exprimés dans les cellules germinales à l'aide de techniques de séquençage à grande échelle a permis d'identifier de nouveaux miARN spécifiquement exprimés dans le testicule prépubère [11].…”
