Abstract

Introduction: Increasing evidence indicates that microRNAs (miRNAs) play a crucial role in modulating tumor growth. This study is centered on investigating the contribution of miR-25 to the progression of Renal Cell Carcinoma (RCC). Methods: The investigators examined the expression levels of miR-25 and ADAMTS16 in RCC samples and cell lines. The association between miR-25 and ADAMTS16 was validated via a luciferase reporter assay. Cell viability, apoptosis, migration, and invasion were evaluated utilizing CCK-8 and flow cytometry techniques, while the expression levels of ADAMTS16, β-catenin, GSK-3β, and p-GSK-3β were assessed through western blot analysis. Results: The investigation revealed elevated expression levels of miR-25 in RCC tissues. Subsequently, ADAMTS16 was identified as a target of miR-25. Increased miR-25 levels were associated with decreased expression of ADAMTS16, resulting in enhanced cell viability and diminished apoptosis. Conversely, inhibition of miR-25 led to decreased cell viability, proliferation, and migration. Additionally, the researchers observed that miR-25 triggered the phosphorylation of GSK-3β and β-catenin while leaving the total GSK-3β level unaffected. Conclusion: This study suggests that miR-25 regulates the expression of ADAMTS16 through the Wnt/β-catenin signaling pathway, providing new insights into the cause and potential treatment of RCC.
