ABSTRACT
Wilms' tumor (WT) is a most common renal cancer that occurs among children, and microRNA-19b (miR-19b) usually participates in various human cancers. Importantly, the PTEN/PI3K/Akt signaling pathway plays a key role in cell apoptosis, growth and proliferation. Thus, our present study aims to investigate the effect of miR-19b on the PTEN/PI3K/Akt signaling pathway during WT cell proliferation, migration, and apoptosis. WT tissues and adjacent normal tissues from WT patients were collected. qRT-PCR was applied to detect miR-19b expression in both the WT tissues and the adjacent normal tissues, immunohistochemistry was applied to detect the protein expressions of PTEN, P13K, and p-Akt, SK-NEP-1 cells were divided into the blank, negative control (NC), miR-19b mimics and miR-19b inhibitors groups. MTT assay, propidium iodide (PI) staining, Annexin-V/PI double-staining, Transwell assay and Western blotting were performed to examine cell proliferation, cycle, apoptosis, migration, and invasion, and the protein expressions of PTEN, P13K, Akt, and p-Akt. Increased miR-19b expression, positive expression rates of P13K and Akt, decreased PTEN expression rate, a negative correlation between PTEN expression and tumor lymph node metastasis, and a positive correlation between the expression of P13K and Akt and the clinical stages were observed in the WT tissues. The miR-19b inhibitors group exhibited decreased cell proliferation, cell cycle progression, migration and invasion, and protein expressions of PI3K and p-Akt but increased PTEN protein expression compared with the blank and NC groups. Thus, inhibition of miR-19b suppresses the progression of WT by modulating the PTEN/PI3K/AKT signaling pathway. J. Cell. Biochem. 118 3424-3434, 2017. © 2017 Wiley Periodicals, Inc.
