MiR-142-3p could serve as a potential biomarker for individualized treatment of solitary and multiple leiomyomas
Abstract Background: The pathogenesis and clinical behaviors between solitary leiomyoma (SL) and multiple leiomyomas (ML) vary, which lead to the difference in management for childbearing-aged patients. Herein, we aim to find the potential miRNA biomarkers for optimizing the individualized management between SL and ML.Methods: A microarray analysis was conducted to screen out the potentially dysregulated miRNAs. Target genes and signaling pathway potentially involved in UL pathogenesis were predicted by bioinformatics. The effect of miRNA was examined by Cell Counting Kit-8 proliferation assay and qRT-PCR after transfection of miRNA mimicsResults: The top 5 differentially expressed miRNAs, Wnt signalling pathway and its two central molecules APC and CTNNB1 were screened out according to microarray analysis and bioinformatics. MiR-142-3p was selected for further exploration. In validation of qRT-PCR, MiR-142-3p was significantly upregulated in SL, while downregulated in ML, CTNNB1 and sequencing target AXIN-2 were expressed at higher level in ML than SL. Overexpression of MiR-142-3p resulted in lower transcription level of CTNNB1 and AXIN-2, and lower cell proliferation level.Conclusions: MiR-142-3p may be involved in the development of SL and ML by interacting with CTNNB1 and AXIN-2 through Wnt signaling pathway. MiR-142-3p could serve as a potential biomarker for individualized treatment between SL and ML in the future.
