BACKGROUND: Non-syndromic cleft lip and/or palate (NSCL/P) is a common maxillofacial birth defect, and the etiology of which is complex and still unclear. Accumulating studies indicate that long non-coding RNAs(lncRNAs) and microRNAs(miRNAs) play important roles in NSCL/P. However, the potential regulatory associations remain largely unknown. In this study, we screened differentially expressed miRNAs and constructed competing endogenous RNA (ceRNA) networks to lay a foundation for further research on the regulatory mechanism of ncRNAs in NSCL/P.
METHODS: NSCL/P plasma RNA was analyzed by miRNA sequencing. The bioinformatics database, GEO and STRING database, GO and KEGG enrichment analysis and Cytoscape software were used to analyze and screen lncRNAs and mRNAs potentially related to differential miRNAs. The expression levels of lncRNA, miRNA and mRNA in ceRNA network were detected by RT-qPCR.
RESULTS: In NSCL/P plasma samples, there were 47 differentially expressed miRNAs in CPO group and 36 differentially expressed miRNAs in CL/P group. GO and KEGG enrichment analysis showed that cell cycle, cell response to DNA damage stimulation, and the TGF-βsignaling pathway were relevant to the formation of NSCL/P. The RT-qPCR results showed that the expression levels of lncRNA NEAT1, hsa-miR-130 b-3p, hsa-miR-212-3p, hsa-miR-200 b-3p and SMAD2 were different in NSCL/P.
CONCLUSIONS: We found that differentially expressed miR-212-3p, miR-200 b-3p and miR-130 b-3p may be involved in the pathogenesis of cleft palate by regulating related target genes.
