Aim: We aimed to explore potential regulators of coding and noncoding RNAs (ncRNAs) in Co(II) ion-induced myo cytotoxicity.
Materials & methods: We confirmed the toxic effects of Co(II) on mouse skeletal C2C12 myotubes by CoCl2, and performed the expression profiles of circular RNAs (circRNAs), long noncoding RNAs (lncRNAs) and mRNAs using microarray analysis. We constructed co-expression, competing endogenous RNA and cis/trans regulation networks for ncRNAs, and filtered 71 candidate circRNAs with coding potential.
Results: We identify 605 differentially expressed circRNAs, 4409 long noncoding RNAs and 3965 mRNAs. We also provided several ncRNAs regulation networks and presumed functions of circRNAs with coding potential.
Conclusion: Our findings may reveal novel regulatory mechanisms underlying the noxious effects of CoCl2 in skeletal muscle.
