Simultaneous overactivation of Wnt/?-catenin and TGF? signalling by miR-128-3p confers chemoresistance-associated metastasis in NSCLC.

ABSTRACT: Cancer chemoresistance and metastasis are tightly associated features. However, whether they share common molecular mechanisms and thus can be targeted with one common strategy remain unclear in non-small cell lung cancer (NSCLC). Here, we report that high levels of microRNA-128-3p (miR-128-3p) is key to concomitant development of chemoresistance and metastasis in residual NSCLC cells having survived repeated chemotherapy and correlates with chemoresistance, aggressiveness and poor prognosis in NSCLC patients. Mechanistically, miR-128-3p induces mesenchymal and stemness-like properties through downregulating multiple inhibitors of Wnt/?-catenin and TGF-? pathways, leading to their overactivation. Importantly, antagonism of miR-128-3p potently reverses metastasis and chemoresistance of highly malignant NSCLC cells, which could be completely reversed by restoring Wnt/?-catenin and TGF-? activities. Notably, correlations among miR-128-3p levels, activated ?-catenin and TGF-? signalling, and pro-epithelial-to-mesenchymal transition/pro-metastatic protein levels are validated in NSCLC patient specimens. These findings suggest that miR-128-3p might be a potential target against both metastasis and chemoresistance in NSCLC.

Project description:BackgroundNeuro-oncological ventral antigen 1 (NOVA1) is a neuron-specific RNA-binding protein which regulates alternative splicing in the developing nervous system. Recent research has found that NOVA1 plays a significant role in carcinogenesis. In this paper, we examine the role of NOVA1 in non-small cell lung cancer (NSCLC) and its underlying molecular mechanisms.MethodsThe expression of NOVA1 in NSCLC was detected by immunohistochemistry and correlations between NOVA1 expression and clinicopathological factors were analyzed by chi-square tests. Kaplan-Meier survival analysis and the Cox regression model were used to evaluate the predictive effect of prognostic factors. Western blotting, Cell Counting Kit-8, colony formation, apoptosis, migration and invasion assays were used to detect the effects of silencing (si)NOVA1 RNA on Wnt/β-catenin signaling and biological behavior in NSCLC cell lines.ResultsOur study showed that expression of NOVA1 was up-regulated and significantly correlated with poor differentiation (p = 0.020), advanced TNM stage (P = 0.001), T stage (P = 0.001) and lymph node metastasis (P = 0.000) as well as the expression of β-catenin (P = 0.012) in NSCLC. The down-regulation of NSCLC by siRNA significantly inhibited proliferation, migration and invasion and promoted apoptosis in NSCLC cells. Expression of Wnt signaling molecules, including β-catenin, activated β-catenin, cyclin D1, matrix metalloproteinase (MMP)-2 and MMP-7, was also significantly reduced by siNOVA1. The inhibition of Wnt/β-catenin signaling in A549 and H1299 cells by siNOVA1 was reversed after treatment with a β-catenin expression plasmid.ConclusionThe present study suggests that NOVA1 may serve as a potential prognosis biomarker in NSCLC. High NOVA1 expression was associated with poor survival rate. Finally, in vitro experiments verified that NOVA1 promotes NSCLC cell proliferation and invasion by regulating Wnt/β-catenin signaling.

Project description:BackgroundChemotherapeutic agents that modulate cell cycle checkpoints and/or tumor-specific pathways have shown immense promise in preclinical and clinical studies aimed at anti-cancer therapy. MASTL (Greatwall in Xenopus and Drosophila), a serine/threonine kinase controls the final G2/M checkpoint and prevents premature entry of cells into mitosis. Recent studies suggest that MASTL expression is highly upregulated in cancer and confers resistance against chemotherapy. However, the role and mechanism/s of MASTL mediated regulation of tumorigenesis remains poorly understood.MethodsWe utilized a large patient cohort and mouse models of colon cancer as well as colon cancer cells to determine the role of Mastl and associated mechanism in colon cancer.ResultsHere, we show that MASTL expression increases in colon cancer across all cancer stages compared with normal colon tissue (P < 0.001). Also, increased levels of MASTL associated with high-risk of the disease and poor prognosis. Further, the shRNA silencing of MASTL expression in colon cancer cells induced cell cycle arrest and apoptosis in vitro and inhibited xenograft-tumor growth in vivo. Mechanistic analysis revealed that MASTL expression facilitates colon cancer progression by promoting the β-catenin/Wnt signaling, the key signaling pathway implicated in colon carcinogenesis, and up-regulating anti-apoptotic proteins, Bcl-xL and Survivin. Further studies where colorectal cancer (CRC) cells were subjected to 5-fluorouracil (5FU) treatment revealed a sharp increase in MASTL expression upon chemotherapy, along with increases in Bcl-xL and Survivin expression. Most notably, inhibition of MASTL in these cells induced chemosensitivity to 5FU with downregulation of Survivin and Bcl-xL expression.ConclusionOverall, our data shed light on the heretofore-undescribed mechanistic role of MASTL in key oncogenic signaling pathway/s to regulate colon cancer progression and chemo-resistance that would tremendously help to overcome drug resistance in colon cancer treatment.

Project description:BackgroundLung cancer is the most common cancer in the world and is the main cause of cancer-related death. Revealing the potential mechanism of malignant characteristics of lung cancer is urgent for treating this disease effectively. Zinc finger protein 671 (ZNF671) is a member of the largest transcription factor family in the human genome. The role of ZNF671 in non-small-cell lung cancer (NSCLC) remains unknown. The purpose of this study was to investigate the function and mechanism of ZNF671 in NSCLC.MethodsZNF671 expression in NSCLC cells and tissues were detected by Real-Time PCR, Western blot and TCGA databases. Then, we evaluated the prognostic value of ZNF671 expression in NSCLC using the Kaplan-Meier plotter (KM plotter) and TCGA databases. Moreover, the function of ZNF671 in the proliferation and metastasis of lung cancer was investigated by MTT assay, colony formation assay, in vivo experiment, EdU assay, wound healing assay, transwell assay, and 3D culture assay. Luciferase reporter and subcellular fractionation assays were performed to determine the underlying mechanism of ZNF671-mediated proliferation and metastasis of NSCLC.ResultsZNF671 expression was significantly reduced in both NSCLC cell lines and clinical specimens compared to that in normal controls. The survival analysis results indicated that the downregulation of ZNF671 significantly correlates with poor prognosis and predicts a shorter overall survival and post-progression survival among NSCLC patients. Ectopic overexpression of ZNF671 dramatically restrains, whereas silencing ZNF671 enhanced, cell proliferation and metastasis of NSCLC. Mechanically, gene set enrichment analysis (GSEA) showed that the expression of ZNF671 was significantly correlated with Wnt/β-catenin signaling. Simultaneously, our results confirm that the overexpression of ZNF671 inhibits cell cycle progression and metastasis by weakening the Wnt/β-catenin pathway, and then downregulating the expression of downstream target genes CyclinD1 and MMP9.ConclusionThis study found that the overexpression of ZNF671 restrains the proliferation and metastasis of lung cancer through inhibiting Wnt/β-catenin signaling pathway. Furthermore, our current results provide important insights into ZNF671 as an excellent predictive biomarker for NSCLC, thus providing a novel perspective for the treatment of NSCLC.
