Forensic Context

A study in mice demonstrated that the circZNF609 exhibits higher expression in myotubes compared to myoblasts, and its downregulation reduces myoblast proliferation while inhibiting differentiation by sponging miR-194-5p and upregulating BCLAF1 [Di Agostino et al. DOI:10.3389/fcell.2020.00389]. A review consolidating research across multiple species, including human, mouse, rat, and C. elegans, indicates that the circZNF609 is downregulated in Hirschsprung disease and functions as a miRNA sponge for miR-150-5p to regulate AKT3, where its silencing inhibits cell migration and proliferation [Lee et al. DOI:10.1016/j.biopha.2018.12.052]. In mammalian neural tissue, it is also noted to play a role in myoblast differentiation by producing a protein [Suresh L. Mehta et al. DOI:10.1016/j.pneurobio.2020.101746].
