Fig. 6From: Conserved and highly expressed tRNA derived fragments in zebrafishtRFs are conserved among vertebrate species. a Northern blots showing the expression of 5′tRF-GluCTC and 5′tRF-ProCGG in human cell lines (HeLa, HEK293, AGS), a mouse cell line (NIH3T3) and zebrafish cell lines derived from bone (ZFb1, ZFb2). RNA extracted from adult zebrafish muscle was used as a positive control. 5′tRF-GluCTC and 5′tRF-ProCGG were detected in human and zebrafish cell lines, but barely detected in the mouse embryonic fibroblast cell line (NIH3T3). b ClustalW alignments of mature tRNA and tRFs showing high conservation in different species, namely human, mouse and zebrafishBack to article page
