By analogy, MIR6129 could participate as a post‐transcriptional modulator that fine‐tunes LEF1 levels and thereby influences the magnitude and timing of Wnt/β‐catenin–dependent transcription. In such a model, MIR6129 might impact critical processes including cell fate determination, epithelial–mesenchymal transitions, and tissue regeneration or tumorigenesis by indirectly controlling the expression of genes activated by LEF1-containing transcription complexes. Further studies will be required to experimentally validate this putative role of MIR6129 within the intricate network of Wnt signaling and its downstream developmental and oncogenic events."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "13", "end_ref": "24"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Maralice E Conacci-Sorrell, Tamar Ben-Yedidia, Michael Shtutman, et al.
