To be Wild or Mutant: Role of Isocitrate Dehydrogenase 1 (IDH1) and 2-Hydroxy Glutarate (2-HG) in Gliomagenesis and Treatment Outcome in Glioma. Cell Mol Neurobiol 2019; 40:53-63. [PMID: 31485826 DOI: 10.1007/s10571-019-00730-3] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Accepted: 08/23/2019] [Indexed: 12/20/2022]
Abstract
Molecular and clinical research based on isocitrate dehydrogenase (IDH) mutations is much sought after in glioma research since a decade of its discovery in 2008. IDH enzyme normally catalyzes isocitrate to α-keto-glutarate (α-KG), but once the gene is mutated it produces an 'oncometabolite', 2-hydroxyglutarate (2-HG). 2-HG is proposed to inhibit α-KG-dependent dioxygenases and also blocks cellular differentiation. Here, we discuss the role of the IDH1 mutation in gliomagenesis. The review also focuses on the effect of 2-HG on glioma epigenetics, the cellular signaling involved in IDH1 mutant glioma cells and the therapeutic response seen in mutant IDH1(mIDH1) harboring glioma patients in comparison to the patients with wild-type IDH1. The review encompasses the debatable impacts of the mutation on immune microenvironment a propos of various mIDH1 inhibitors in practice or in trials. Recent studies revealing the relation of IDH mutation with the immune microenvironment and inflammatory status in untreated versus treated glioblastoma patients are highlighted with respect to prospective therapeutic targets. Also at the molecular level, the association of mIDH1/2-HG with the intracellular components such as mitochondria and other neighboring cells is discussed.

Analysis of clinical characteristics of macrophage capping protein (CAPG) gene expressed in glioma based on TCGA data and clinical experiments. Oncol Lett 2019; 18:1344-1350.

Abstract
Macrophage capping protein (CAPG) genes were investigated based on The Cancer Genome Atlas (TCGA) database and clinical experiments. Glioblastoma (GBM) genes expression profiling chip of 529 disease samples and 10 normal samples selected from TCGA database were used for analysis, 25 brain glioma tissue samples and 15 normal brain tissues were collected in the Department of Neurosurgery of the First Affiliated Hospital of Xinjiang Medical University in China from 2016 to 2017 to analyze CAPG genes. TCGA results showed that the expression level of CAPG genes in GBM was higher than that in normal tissues, and the expression level of men, aged over 46 years and high grade gliomas in pathological stages was higher than that of women, aged ≤46 and low grade gliomas in pathological stages, and the survival time of high expression was shorter than that of low expression. The expression level of CAPG in glioma tissues was higher than that in normal tissues, and the expression level of CAPG in males was higher than that in females, as males had lymphatic transfer and low differentiation compared with females, but the expression level was not related to age. Survival analysis showed that higher expression level indicated shorter survival time, they were positively correlated. The expression of CAPG in glioma is high, and it is highly expressed with the severity of the disease, and it is also obviously related to the prognosis. Therefore, CAPG could be used as a biomarker for pathological grade and prognosis in glioma. However, the related studies are not consistent on the expression of different sex and ages, so further study is needed.

Abstract
Human glioblastoma multiforme (GBM) accounts for the majority of human brain gliomas. Several TMEM proteins, such as TMEM 45A, TMEM 97, and TMEM 140, are implicated in human brain gliomas. However, the roles of TMEM168 in human GBM remain poorly understood. Herein we found that mRNA levels of TMEM168 were overexpressed in GBM patients (n = 85) when compared with healthy people (n = 10), which was also supported by data from The Cancer Genome Atlas (TCGA). Kaplan-Meier analysis of Gene Expression Omnibus dataset GSE16011 suggested that enhanced TMEM168 expression was associated with shorter survival time. To investigate whether and how TMEM168 functioned in the tumorigenesis of human GBM cells, two human GBM cell lines (U87 and U373) were used for study. Lithium chloride (LiCl), an activator for Wnt/β-catenin pathway, was used for the treatment. Our data suggested that siRNA-TMEM168 (siTMEM168) prevented viability of U87 and U373 cells, induced cell cycle arrest (G0/G1 phase) and promoted apoptosis, and the mechanisms involved in blocking Wnt/β-catenin pathway, as evidenced by reducing expression of β-catenin, C-myc, cyclin D1, and survivin. Furthermore, the inhibited effect of siTMEM168 on human GBM cell growth was significantly alleviated with additional LiCl treatment, substantiating the involvement of the Wnt/β-catenin pathway in this process. In summary, our data demonstrated that TMEM168 may represent a therapeutic target for the treatment of human GBM.

Abstract
The PAX3 (paired box 3) gene plays an important role in embryonic development, diseases, and cancer formation. Our preliminary studies have shown that PAX3 gene is upregulated in glioma cells, which is associated with a worse prognosis. Moreover, PAX3, by facilitating cell proliferation and invasion and inhibiting cell apoptosis, plays an oncogenic role in glioma. However, the specific molecular mechanism of PAX3 acting as an oncogene in glioma remains unclarified. In the present study, we have found that PAX3 overexpression was observed in high grade glioma and predicted a worse prognosis. PAX3 overexpression did not correlate significantly to IDH1 mutation and MGMT methylation. Moreover, the expression of PAX3 was positively correlated with that of β-catenin. In U87 glioma cells, PAX3 interacted with β-catenin, as was confirmed by CO-IP. Besides, PAX3 overexpression promoted cell proliferation and cell cycle progression, while it inhibited cell apoptosis by altering the expressions of important molecules associated with the Wnt signaling pathway, including β-catenin, Myc, VEGF, cyclinD1, MMP7, and Wnt1. In the meantime, it was also proved that PAX3 correlated to β-catenin through a negative regulatory mechanism with respect to the promotion of U87 glioma cell proliferation and cell cycle progression and inhibition of the cell apoptosis. Our experiment demonstrated the role of PAX3 in promoting glioma growth and development, possibly by interacting directly with β-catenin and regulating the Wnt signaling pathway.

Abstract
Objective: Human brain glioma is the most malignant primary intracranial tumor, which has poor prognosis and high mortality. Long noncoding RNAs are considered to take part in cellular phenotypes and are emerging as diagnostic and prognostic biomarkers of glioma. This study will research the effects of Small Nucleolar RNA Host Gene 5 (SNHG5) gene on malignant cellular phenotypes in glioma and explore the possible mechanisms. Materials and Methods: The expression level of SNHG5 was examined using quantitative Real-time PCR in glioma tissues and cell lines. Loss-of-function experiments of SNHG5 together with Enhanced Cell Counting Kit-8, flow cytometry and cell invasion assay were used to investigate the effects of SNHG5 on malignant cellular phenotypes of glioma cells. Finally, luciferase assay and western blotting were applied to determine the activity of WNT/CTNNB1 signaling pathway. Results: SNHG5 gene was high-expressed in glioma tissues and cell lines. Knockdown of SNHG5 gene depressed cell proliferation and invasiveness as well as promoted the apoptosis of U251 and U87 cells. In addition, online database analysis showed SNHG5 was closely related to Wnt/CTNNB1 signaling pathway. Knockdown of SNHG5 inactivated Wnt/CTNNB1 signaling pathway, and the activating of Wnt/CTNNB1 signaling pathway partly restored the influences of SNHG5 knockdown on malignant cellular phenotypes of U251 and U87 cells. Conclusion: SNHG5 gene was high-expressed in glioma, knockdown of SNHG5 inhibits malignant cellular phenotypes of glioma via Wnt/CTNNB1 signaling pathway.

Abstract
Aberrant activation of Wnt signaling has been implicated in human osteosarcoma, which may provide a genetic vulnerability that can be targeted in osteosarcoma treatment. To test whether Wnt activation is necessary for osteosarcoma growth, colony formation, invasion, and metastasis, we treated human osteosarcoma cells with a small molecule inhibitor of Wnt/β-catenin, PRI-724, which suppresses Wnt/β-catenin-mediated transcription. We found increased protein levels of endogenous active-β-catenin in five human osteosarcoma cell lines. Treatment with PRI-724 was sufficient to inhibit human osteosarcoma 143B and SJSA-1 cell proliferation. Suppressed Wnt signaling was confirmed by decreased protein levels of the Wnt target Cyclin D1. Furthermore, we revealed significant inhibitory effects on cell migration, invasion, and colony formation in the human osteosarcoma cells. Using deposited data from next generation sequencing studies, we analyzed somatic mutations and gene expression of components in the Wnt/β-catenin pathway. We found somatic mutations and upregulated gene expression of many components in the Wnt/ β-catenin pathway, indicating activated Wnt signaling. Taken together, our results illustrate the critical role of Wnt/β-catenin signaling in human osteosarcoma pathogenesis and growth, as well as the therapeutic potential of Wnt inhibitors in the treatment of human osteosarcoma.

Abstract
This article was aimed to study the FOXF2 effects on cervical cancer. Tumor tissues and adjacent tissues of 41 cervical cancer patients were collected. Human endometrial epithelial cells (hEEC) and Hela cells were cultured. FOXF2 expression vector and its empty vector were transfected into Hela cells, and named as pcDNA 3.1-FOXF2 group and Vector group, respectively. Hela cells without any treatment were set as Blank group. qRT-PCR was used to detect mRNA expression. Nude mouse xenograft assay was performed to test Hela cells proliferation ability in vivo. FOXF2 and β-catenin positive cell numbers were detected by immunohistochemistry. Protein expression was analyzed by Western blot. Cells migration and invasion were conducted by Transwell. Tumor tissues and Hela cells FOXF2 expression were lower than that in adjacent tissues and hEEC (P<0.01). Low FOXF2 expression predicted poor outcomes of cervical cancer patients. Compared with Blank group and Vector group, Hela cells of pcDNA 3.1-FOXF2 group were with higher FOXF2 expression, lower OD495 value, migrated and invaded cells, higher E-cadherin expression, lower Vimentin and Snail expression, smaller tumor volume in nude mice, lower c-Myc, CyclinDl, MMP9, Lgr5, and nuclear β-catenin expression (all P<0.01). FOXF2 inhibits Hela cells proliferation, migration, and invasion through regulating Wnt signaling pathway.

Abstract
Breast cancer is a major public health concern, due to its increasing incidence and limited effective treatment. The present study aimed to investigate the expression of microRNA (miR)‑194‑5p and its roles in breast cancer. The expression levels of miR‑194‑5p and SRY‑box 17 (SOX17) mRNA were detected in breast cancer tissues and cell lines by reverse transcription‑quantitative polymerase chain reaction. The protein expression levels were determined by western blotting. In addition, MTT, colony formation, scratch and Transwell assays were use to evaluate the characteristics of MCF‑7 cells with miR‑194‑5p knockdown. The target verification of miR‑194‑5p was determined by luciferase reporter assay. Furthermore, tumor‑bearing nude mice with miR‑194‑5p knockdown were used to assess the effects of miR‑194‑5p on tumor activity. In breast cancer tissues, miR‑194‑5p was upregulated, whereas SOX17 was downregulated. In addition, the expression levels of SOX17 and phosphorylated (p)‑β‑catenin in the cytosol and nucleus were increased in the miR‑194‑5p inhibitor group. In addition, cell proliferation, migration and invasion were inhibited in response to miR‑194‑5p knockdown. The luciferase reporter assay confirmed that SOX17 was a target gene of miR‑194‑5p. In the mouse studies, knockdown of miR‑194‑5p suppressed tumor growth and promoted SOX17 expression in nude mice with breast cancer. These findings suggested that knockdown of miR‑194‑5p may increase the expression of SOX17 and regulate the Wnt/β‑catenin signaling pathway in breast cancer cells; therefore, miR‑194‑5p may be considered a potential target for breast cancer prevention.

Abstract
Aberrant nitric oxide synthase 2 (NOS2) expression has been suggested as an interesting therapeutic target that is being implicated as a component of the molecular profile of several human malignant tumors, including glioblastoma, which is the most aggressive brain tumor with limited therapeutic options and poor prognosis. The aim of the present work was to evaluate the effect of 1400W, a specific NOS2 inhibitor, on human glioma cells in terms of clonogenic potential, proliferation, migration rate, and neurosphere generation ability. NOS2 expression was determined by Western blotting. Nitric oxide (NO) production was measured through nitrite level determination. The trypan blue exclusion test and the plate colony formation assay were performed to evaluate cell proliferation and clonogenic potential. Cell proliferation and migration ability was assessed by the in vitro wound-healing assay. Neurosphere generation in a specific stemcell medium was investigated. NOS2 was confirmed to be expressed in both the glioma cell line and a human glioma primary culture, and overexpressed in relative derived neurospheres. Experiments that aimed to evaluate the influence of 1400W on U-87 MG, T98G (glioblastoma cell lines) and primary glioma cells sustained the crucial role played by NOS2 in proliferation, colony formation, migration, and neurosphere generation, thus supporting the emerging relevance of a NOS2/NO system as a prognostic factor for glioma malignancy and recurrence.

Abstract
Glioma is the most common primary malignant brain tumor in adults. Forkhead box k1 (FOXK1) was reported to be dysregulated and play important roles in multiple human cancers. However, the expression pattern and roles of FOXK1 in glioma has never been investigated. In this study, we firstly observed that the expression of FOXK1 was significantly increased in glioma tissue samples and cell lines. Functional assays demonstrated that overexpression of FOXK1 promoted proliferation, cell cycle transition and inhibited apoptosis in glioma cell lines. On the contrary, knockdown of FOXK1 exhibited an opposite effect on glioma cells proliferation, cell cycle and apoptosis. Data of western blot indicated that FOXK1 overexpression increased while FOXK1 knockdown decreased the levels of β-catenin, c-myc and cyclinD1 in glioma cells. Moreover, we demonstrated that FOXK1 was a novel target of miR-137 in glioma and FOXK1 restoration abolished the tumor suppressive effect of miR-137 in glioma cells. Statistical analysis showed that the mRNA level of FOXK1 was inversely correlated with miR-137 expression in glioma tissues. In conclusion, the present study demonstrated that FOXK1 promoted cell growth through activating wnt/β-catenin pathway and is negatively regulated by miR-137 in glioma.
