AbstractmicroRNAs (miRNAs) have been found to affect various cancers, and expression of numerous miRNAs is revealed in glioma. However, the role of microRNA-30b-3p (miR-30b-3p) in glioma remains elusive. Therefore, the present study aims to explore the specific mechanism by which miR-30b-3p influence the development of glioma in relation to the AKT signaling pathway. First, glioma cell lines were collected with miR-30b-3p and reversion-inducing cysteine-rich protein with kazal motifs (RECK) expression measured. The functional role of miR-30b-3p and RECK in glioma was determined via gain- and loss-of-function approaches. Subsequently, the expression of invasion- and migration-related factors (MMP-2 and MMP-9) and the AKT signaling pathway-related factors (AKT, p-AKT and PI3K-p85) was detected. Moreover, in vivo experiments were also conducted to investigate how miR-30b-3p influences in vivo tumorigenesis. The results showed that miR-30b-3p was up-regulated and RECK was down-regulated in glioma. RECK was a target gene of miR-30b-3p. Decreased miR-30b-3p and overexpressed RECK led to decreased expression of MMP-2, MMP-9 and p-AKT. Overexpressed RECK and LY294002 could decrease p-AKT and PI3K-p85 expression accompanied with unchanged expression of total protein of AKT. Additionally, proliferation, migration and invasion of glioma cells and tumor formation in nude mice were repressed owing to reduced expression of miR-30b-3p or elevated expression of RECK. In summary, miR-30b-3p inhibition suppresses metastasis of glioma cells by inactivating the AKT signaling pathway via RECK up-regulation, providing a new target for glioma treatment.

Hepatocellular carcinoma (HCC) is a serious threat to human health. miR-340 participates in HCC pathogenesis, but its specific mechanism is not completely clear. Therefore, our study assessed the mechanism by how miR-340 involves in HCC. The cancer tissues and paracancerous tissues of HCC patients were collected. miR-340 mimics/NC and Akt siRNA were transfected into HepG2 cells followed by analysis of miR-304 and EMT-related molecules expression by Real-time PCR, cell invasion and migration by Transwell assay, cell proliferation ability by CCK8 assay as well as p-Akt and p-mTOR level by Western blot. miR-340 in HCC tissues was significantly downregulated compared to adjacent tissues (P <0.001). With increased pathological grade, miR-340 expression was decreased gradually. p-Akt and p-mTOR in HCC tissues was significantly upregulated and elevated gradually with increased pathological grade. p-Akt and p-mTOR was negatively associated with miR-340 (P <0.001). After overexpression of miR-340, HepG2 cell proliferation, invasion, migration and epithelialization were significantly inhibited, and p-Akt and p-mTOR was reduced. When Akt expression was interfered with siRNA, cell proliferation and epithelialization was further inhibited. miR-340 inhibits the development of hepatocellular carcinoma through Akt signaling pathway.

Abstract BackgroundInsulin-like growth factor 2 (IGF2) mRNA-binding protein 2 (IGF2BP2), as a m6A “reader”, is known to be an oncogene, and its expression is elevated in multiple tumors. However, the role of IGF2PB2 in esophageal squamous cell carcinoma (ESCC) is still unclear. MethodsThis study aims to investigate the role of IGF2PB2 expression in ESCC proliferation, invasion and migration as well as the possible mechanism. IGF2BP2 expression was found to be elevated in ESCC tissues by qRT-PCR, western blotting, and immunohistochemical (IHC) staining. ResultsKnocking down IGF2BP2 expression prevented the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of KYSE450 and TE1 cells. Knocking out IGF2BP2 reduced tumorigenesis in vivo. Overexpression of IGF2BP2 was performed, and it was proven that IGF2BP2 had an oncogenic effect in KYSE450 and TE1 cells. Moreover, LY294002, a highly selective inhibitor of PI3K, reversed the effect of IGF2BP2 overexpression on EMT processes. All these results show that the effects of IGF2BP2 on oncogenesis and EMT were clearly exerted via the PI3K/AKT signaling pathway. ConclusionsIn conclusion, this study demonstrates that the oncogenic function of IGF2BP2 is mediated by the PI3K/AKT signaling pathway and is related to EMT in ESCC. In addition, IGF2BP2 can serve as a diagnostic and oncotherapeutic marker in further studies.
