Abstract
Wiskott-Aldrich syndrome protein family verprolin-homologous domain-containing protein 3 (WAVE3) is reported as an oncogene regulating cell proliferation and motility in multiple malignancies, while its role in tongue squamous cell carcinoma (TSCC) remains unknown. This study aimed to explore the expression and mechanism of WAVE3 in TSCC. We enrolled 64 TSCC patients admitted between June 2013 and February 2014 and collected their cancerous and adjacent normal tissues to determine WAVE3 expression by immunohistochemistry. The correlation of WAVE3 expression with TSCC patients' pathological characteristics was analyzed. Then, a 7-year follow-up was conducted to observe the value of WAVE3 in evaluating patient outcomes. In addition, human TSCC SCC9, SCC25, and CAL27 cells were purchased and detected by Cell Counting Kit-8 (CCK-8), Transwell, and scratch-wound assays for their proliferation, invasion, and migration capacities, while real-time quantitative PCR (qRT-PCR) and Western blotting were utilized to quantify WAVE3 and epithelial-mesenchymal transition (EMT)-related protein expression, respectively. The most active cell lines were selected to be infected with lentiviral vectors that silenced WAVE3 (named WAVE3-sh group) and overexpressed WAVE3 cDNA (named WAVE3-OE group) to observe the impacts of interfering WAVE3 expression on TSCC cell biological behavior. The positive expression of WAVE3 in TSCC tissue was found to be obviously enhanced and predominantly located in the cytoplasm. In addition, close correlations were identified between WAVE3 and T staging, clinical staging, lymphatic metastasis, distant metastasis, and differentiation degree (P < 0.05). Increased WAVE3 expression predicted an elevated risk of death, as indicated by the follow-up analysis (P < 0.05). SCC9 was selected for subsequent experiments among various TSCC cell lines studied because it showed the most potent ability to proliferate, invade, and migrate (P < 0.05). Silencing WAVE3 expression in SCC9 cells decreased cell proliferation, invasion, migration, and EMT-related protein expression (P < 0.05), while increasing WAVE3 expression promoted SCC9 viability. WAVE3, which was highly expressed in TSCC, promoted EMT in tumor cells and accelerated their proliferation, invasion, and migration, which might provide a new theoretical basis for molecular targeted therapy of TSCC in the future.

Yi Q, Huang M, Zhang X, Xu Z, Sun J, Wang S, Xu H, Du Z, Liu M. GNA13 inhibits glioblastoma metastasis via the ERKs/FOXO3 signaling pathway. Cell Signal 2023:110789. [PMID: 37392861 DOI: 10.1016/j.cellsig.2023.110789] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 06/21/2023] [Accepted: 06/28/2023] [Indexed: 07/03/2023]
Abstract
Glioblastoma (GBM) is a malignant tumor characterized by poor prognosis and low overall survival (OS) rate. Identification of novel biological markers for the diagnosis and treatment of GBM is crucial to developing interventions to improve patient survival. GNA13, a member of the G12 family, has been reported to play important roles in a variety of biological processes involved in tumorigenesis and development. However, its role in GBM is currently unknown. Here, we explored the expression patterns and functions of GNA13 in GBM, as wells its impact on metastasis process. Results showed that GNA13 was downregulated in GBM tissues and correlated with poor prognosis of GBM. Downregulation of GNA13 promoted the migration, invasion and proliferation of GBM cells; whereas its overexpression abolished these effects. Western blots revealed that GNA13 knockdown and overexpression upregulated and inhibited the phosphorylation of ERKs, respectively. Moreover, GNA13 was the upstream of ERKs signaling to regulating ERKs phosphorylation level. Furthermore, U0126 alleviated the metastasis effect induced by GNA13 knockdown. Bioinformatics analyses and qRT-PCR experiments demonstrated that GNA13 could regulate FOXO3, a downstream signaling molecule of ERKs pathway. Overall, our results demonstrate that GNA13 expression is negatively correlated with GBM and can suppress tumor metastasis by inhibiting the ERKs signaling pathway and upregulating FOXO3 expression.

The diagnostic and prognostic potential of the EGFR/MUC4/MMP9 axis in glioma patients. Sci Rep 2022; 12:19868. [PMID: 36400876 PMCID: PMC9674618 DOI: 10.1038/s41598-022-24099-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 11/10/2022] [Indexed: 11/19/2022] Open
Abstract
Glioblastoma is the most aggressive form of brain cancer, presenting poor prognosis despite current advances in treatment. There is therefore an urgent need for novel biomarkers and therapeutic targets. Interactions between mucin 4 (MUC4) and the epidermal growth factor receptor (EGFR) are involved in carcinogenesis, and may lead to matrix metalloproteinase-9 (MMP9) overexpression, exacerbating cancer cell invasiveness. In this study, the role of MUC4, MMP9, and EGFR in the progression and clinical outcome of glioma patients was investigated. Immunohistochemistry (IHC) and immunofluorescence (IF) in fixed tissue samples of glioma patients were used to evaluate the expression and localization of EGFR, MMP9, and MUC4. Kaplan-Meier survival analysis was also performed to test the prognostic utility of the proteins for glioma patients. The protein levels were assessed with enzyme-linked immunosorbent assay (ELISA) in serum of glioma patients, to further investigate their potential as non-invasive serum biomarkers. We demonstrated that MUC4 and MMP9 are both significantly upregulated during glioma progression. Moreover, MUC4 is co-expressed with MMP9 and EGFR in the proliferative microvasculature of glioblastoma, suggesting a potential role for MUC4 in microvascular proliferation and angiogenesis. The combined high expression of MUC4/MMP9, and MUC4/MMP9/EGFR was associated with poor overall survival (OS). Finally, MMP9 mean protein level was significantly higher in the serum of glioblastoma compared with grade III glioma patients, whereas MUC4 mean protein level was minimally elevated in higher glioma grades (III and IV) compared with control. Our results suggest that MUC4, along with MMP9, might account for glioblastoma progression, representing potential therapeutic targets, and suggesting the 'MUC4/MMP9/EGFR axis' may play a vital role in glioblastoma diagnostics.

Abstract
Long non-coding RNAs (lncRNAs) serve an important role in tumor progression, and their abnormal expression is associated with tumor development. The lncRNA narcolepsy candidate region 1 gene C (lnc-NLC1-C) is involved in numerous types of cancer, but its biological function in glioma remains unknown. In the present study, lnc-NLC1-C expression was detected using reverse transcription-quantitative (RT-q)PCR in U251, SHG44, U87MG and U118MG glioma cells. U87MG cells were transfected with lnc-NLC1-C overexpression or interference vectors. Cell proliferation was detected using a Cell Counting Kit-8 assay. Cell migration and invasion were examined using a Transwell assay, while apoptosis, cell cycle and reactive oxygen species production were evaluated using flow cytometry, and the expression levels of lnc-NLC1-C, microRNA (miR)-383 and peroxiredoxin 3 (PRDX-3) were measured using western blotting and RT-qPCR. Rescue experiments were performed to verify the function of the lnc-NLC1-C/miR-383/PRDX-3 axis. The highest expression levels of lnc-NLC1-C were identified in U87MG glioma cells. Overexpression of lnc-NLC1-C expression promoted cell proliferation, G1 phase blocking, migration and invasion, while inhibiting apoptosis and autophagy in U87MG cells. Mechanistically, miR-383 could bind to lnc-NLC1-C to regulate PRDX-3 expression and improve its oncogenic effect. Rescue experiments confirmed that the lnc-NLC1-C/miR-383/PRDX-3 axis was involved in the molecular mechanism of glioma progression. Therefore, lnc-NLC1-C may be a tumor promoter that affects multiple biological functions, such as migration, invasion and autophagy, in glioma cells.

Abstract
Glioblastoma is one of the most common primary nervous system tumors and has a high mortality rate. It is necessary to explore a novel biological target and treatment approach. Twisted gastrulation signaling modulator 1 (TWSG1) is expressed in many tumors and closely related to tumor growth and proliferation. However, there is almost no report about the mechanism of TWSG1 in glioma. We used a glioma chip to detect the expression level of TWSG1 by Immunohistochemistry. The overexpression and silence experiments of TWSG1 were performed to assay the biological function of TWSG1 in LN229 and U251 cells. Subcutaneous xenograft mouse model presented the effect of TWSG1 expression on the malignant behavior of tumor cells. Experimental results displayed that the expression level for TWSG1 was substantially elevated in gliomas compared to that in normal brain tissue. The expression knockdown of TWSG1 caused inhibition of glioma cell proliferation. Besides, TWSG1 overexpression enhanced proliferation in glioma cells, and the capacity of proliferation was partly abolished by the PI3K inhibitor LY294002. We found that TWSG1 affected the activity of Akt signaling pathway. In conclusion, TWSG1 is overexpressed in glioma tissue and promotes tumor proliferation through Akt signaling pathway, may serve as a potential target for glioma diagnosis and therapy.

Abstract
BACKGROUND MUC15, one of the hydrophilic glycoproteins that protect wet-surfaced epithelia, has been shown to be involved in tumorigenesis of various tumors. However, the mechanism of MUC15 in pancreatic cancer have not been revealed yet. Our study focused on investigating its clinical significance and function in pancreatic cancer. MATERIAL AND METHODS Using tissue microarrays and immunohistochemical staining, we evaluated MUC15 expression in 92 patients diagnosed with pancreatic ductal adenocarcinoma (PDAC). The correlations between MUC15 expression and clinicopathological variables and prognosis were analyzed. To validate our findings, we analyzed the data from an online database. We then demonstrated its function or mechanism in pancreatic cancer cell lines using transwell assay, cytotoxicity assay, cell apoptotic detection, and western blot. RESULTS The expression level of MUC15 was remarkably increased in PDAC tissues in comparison with para-cancerous tissues, and was associated with poor prognosis. Cytoplasmic MUC15 expression was identified as an independent prognostic indicator for overall survival by multivariate Cox regression analysis. Functionally, overexpressed MUC15 enhanced the migration and invasion ability in cancer cells. In vitro studies revealed that MUC15 enhanced the gemcitabine resistance of pancreatic cancer. Additionally, the regulatory mechanism of MUC15 in PDAC were correlated with ERK and AKT signaling pathways. CONCLUSIONS We performed integrated analysis and revealed that MUC15 is a good prognostic predictor for patients with PDAC. The functional experiments showed that MUC15 contributed to the malignant behaviors of pancreatic cancer in vitro.
