The involvement of microRNAs (miRNAs) in cancer development and their potential
as prognostic biomarkers are becoming increasingly known. However, the signature
of miRNAs and their regulatory roles in tumorigenesis of upper tract urothelial
carcinoma (UTUC) remain to be elucidated. This study aimed to profile the miRNA
expression pattern in UTUC tumor tissues and identify candidate miRNAs with
prognostic and/or therapeutic functions. METHODS AND RESULTS: We collected 22
UTUC tissue and adjacent normal tissues samples from patients who underwent
nephroureterectomy. The miRNAs signatures of three selected UTUC samples using
next-generation sequencing showed that miR-30a-5p was significantly downregulated
in UTUC tumors compared to adjacent normal tissues. The differentially-expressed
miRNAs were specifically validated by quantitative real-time polymerase chain
reaction. In addition, the miRNA expression signatures were analyzed with the
transcriptome profile characterized by microarray. Further in vitro studies
indicated that overexpression of miR-30a-5p significantly suppressed
proliferation, migration, and epithelial-to-mesenchymal transition (EMT) in
cultured BFTC-909 UTUC cells. As a potential target gene of miR-30a-5p in the
tight junction pathway suggested by the pathway enrichment analysis, the reduced
expression of tight junction protein claudin-5 in UTUC cells was demonstrated to
be upregulated by miR-30a-5p genetic delivery. CONCLUSIONS: Taken together, our
findings demonstrated that miR-30a-5p inhibits proliferation, metastasis, and
EMT, and upregulates the expression of tight junction claudin-5 in UTUC cells.
Thus, miR-30a-5p may provide a promising therapeutic strategy for UTUC treatment.
