MiR-142-3p May Be Involved in the Development of Solitary and Multiple Uterine Leiomyomasby Interacting with CTNNB1 and AXIN-2 Through Wnt Signaling Pathway

Abstract Background The pathogenesis and clinical behaviors between solitary uterine leiomyoma (SUL) and multiple uterine leiomyomas (MUL) vary, which lead to the difference in management for childbearing-aged patients. Herein, we aim to find the potential miRNAs involved in the development of SUL and MUL. Results 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 SUL, while downregulated in MUL, CTNNB1 and sequencing target AXIN-2 were expressed at higher level in MUL than SUL. 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 SUL and MUL by interacting with CTNNB1 and AXIN-2 through Wnt signaling pathway. MiR-142-3p could serve as a potential biomarker for individualized treatment between SUL and MUL in the future.

Peripheral Leukocytes

Abstract Background and purpose- MicroRNAs (miRNAs) in exosomes had been implicated differentially expressed in MMD patients, but the miRNAs expression in circulating leukocytes remains unclear. This study was investigated on the differential expression of miRNAs in peripheral leukocytes between MMD patients and healthy adults, and among patients with subtypes of MMD.Methods- A total of 30 patients with MMD and 10 healthy adults were enrolled in a stroke center from October 2017 to December 2018. The gene microarray was used to detect the differential expression profiles of miRNA in leukocytes between MMD patients and controls, and the differentially expressed miRNAs were verified by the method of real-time PCR. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to explore the key signaling pathways and possible pathogenesis of MMD.Results- The microarray results showed 12 differentially expressed miRNAs in leukocytes of MMD patients compared with controls (fold change > 2.0 and P < 0.05), of which 7 miRNAs were up-regulated (miRNA-142-5p, miRNA-29b-3p, miRNA-424-5p, MiRNA-582-5p, miRNA-6807-5p, miRNA-142-3p, miRNA-340-5p), and 5 miRNAs were down-regulated (miRNA-144-3p, miRNA-144-5p, miRNA-451a, miRNA-486-5p, miRNA-363-3p). The real-time PCR confirmed 7 differentially expressed miRNAs (P<0.05), of which 4 miRNAs (miRNA-29b-3p, miRNA-142-3p, miRNA-340-5p, miRNA-582-5p) were up-regulated, and 3 miRNAs (miRNA-363-3p, miRNA-451a and miRNA-486-5p) were down-regulated. Both GO and KEGG analysis suggested that the Wnt signaling pathway may be involved in the pathogenesis of MMD. In addition, miRNAs were also differentially expressed among patients with subtypes of MMD. Conclusion- This study indicated that miRNAs are differentially expressed in peripheral leukocytes between MMD patients and healthy adults, and among patients with subtypes of MMD. The Wnt signaling pathway is probably involved in the pathogenesis of MMD.
