Abstract
Background Meningiomas are one of the most common intracranial tumors, and the current understanding of meningioma pathology is still incomplete. Inflammatory factors play an important role in the pathophysiology of meningioma, but the causal relationship between inflammatory factors and meningioma is still unclear. Method Mendelian randomization (MR) is an effective statistical method for reducing bias based on whole genome sequencing data. It's a simple but powerful framework, that uses genetics to study aspects of human biology. Modern methods of MR make the process more robust by exploiting the many genetic variants that may exist for a given hypothesis. In this paper, MR is applied to understand the causal relationship between exposure and disease outcome. Results This research presents a comprehensive MR study to study the association of genetic inflammatory cytokines with meningioma. Based on the results of our MR analysis, which examines 41 cytokines in the largest GWAS datasets available, we were able to draw the relatively more reliable conclusion that elevated levels of circulating TNF-β, CXCL1, and lower levels of IL-9 were suggestive associated with a higher risk of meningioma. Moreover, Meningiomas could cause lower levels of interleukin-16 and higher levels of CXCL10 in the blood. Conclusion These findings suggest that TNF-β, CXCL1, and IL-9 play an important role in the development of meningiomas. Meningiomas also affect the expression of cytokines such as IL-16 and CXCL10. Further studies are needed to determine whether these biomarkers can be used to prevent or treat meningiomas.

Abstract
Methylation of the neurofibromatosis type 2 (NF2) gene in low-grade meningioma (WHO grade I) has crucial roles in tumorigenesis and development. Meningioma formation might also occur in the setting of an inflammatory microenvironment. However, the association between inflammation and the methylation of NF2 remains unclear. The present study investigates the role and regulatory mechanism of IL-1β, one of the most important pro-inflammatory cytokines, in the methylation of NF2 in benign meningioma. Three primary low-grade meningioma cells and leptomeningeal cells were cultured. CCK-8 and BrdU assays demonstrated that proliferation of meningioma/leptomeningeal cells treated with IL-1β occurred in a dose- and time-dependent manner. Methylation-specific PCR verified that IL-1β induced methylation of the NF2 promoter and decreased NF2/merlin expression in meningioma/leptomeningeal cells. Real-time PCR, western blotting, and immunofluorescence showed that IL-1β up-regulated DNMT1 in meningioma cells and DNMT1/3b in leptomeningeal cells but did not up-regulate DNMT3a. After co-treatment with the DNMT inhibitor 5-Aza-2'-deoxycytidine and DNMT siRNA, methylation of NF2 induced by IL-1β was attenuated and merlin expression was restored. Furthermore, we showed that DNMT1 in meningiomas and DNMT1/3b in leptomeninges were regulated via activation of the MAPK (p38, ERK, JNK) and NF-κB pathways. These results suggest that IL-1β induces methylation of NF2 by up-regulating DNMT1 in benign meningioma cells and DNMT1/3b in leptomeningeal cells via MAPK and NF-κB pathways. Therefore, NF2 methylation is a linker between IL-1β and tumor development, and DNMTs might be potential therapeutic targets in meningioma for regulating NF2 and inhibiting tumor development. © 2016 Wiley Periodicals, Inc.

Abstract
The role of transforming growth factor-beta (TGF-beta) in regulation of meningioma growth and intracellular events transducing its signals are not established. In this study, we evaluated the effects of TGF-beta1 on basal meningioma cell proliferation in 10 primary human meningioma cell cultures and whether TGF-beta's signals are transduced by the Smad 2/3, MAPK/Erk kinase-1 (MEK-1)-mitogen-activated protein kinase (MAPK), Akt-p70(S6K) or p38-JUNK pathways in 5. We also tested whether neutralizing antibodies to TGF-beta alter CSF stimulation of meningioma cell proliferation. On average, TGF-beta reduced meningioma cell [3H]-thymidine incorporation to 58% of controls at 24% and to 61% of controls at 36 h. TGF-beta inhibition of meningioma cell proliferation was associated with a suggestion increased phosphorylation of Smad 2/3 in 2 cases and high basal phosphorylation in 3 but no change in activation of the MEK-1-MAPK, Akt-p70(S6K) or p38-JUNK pathways. As shown previously, CSF stimulated meningioma cell proliferation in the 3 cultures tested. Neutralizing antibody against TGF-beta augmented this stimulation in 2 of 3 cultures. These findings suggest that TGF-beta exerts a largely inhibitory effect on basal meningioma proliferation, perhaps in part through Smad 2/3.

Abstract
Malignant meningiomas (MMs) are aggressive intracranial neoplasms with a 75% 5-year recurrence rate. Verotoxin 1 (VT1) is an Escherichia coli toxin, which has recently been shown to have anti-neoplastic action by targeting the globotriosylceramide (Gb(3)) glycolipid on tumor cells and tumor neovasculature. To investigate the potential use of VT1 as a clinical agent for MM, we initially tested 16 meningiomas for Gb(3) expression. Nine of 11 MMs (82%), but only one of five benign meningiomas (20%), were positive for Gb(3). An orthotopic xenograft model was used to test the efficacy of VT1 treatment for MM. We first demonstrated that Gb(3) was highly expressed by the MM cell line, IOMM-Lee, and that this cell line was highly sensitive to VT1 treatment in vitro. A single intratumoral injection of VT1 significantly improved survival in nude mice harboring intracranial tumours (P<.0001). Factor-eight immunostaining of tumours harvested from VT1-treated animals revealed a marked reduction in the tumour microvascular density. In addition, the tumors of VT1-treated animals displayed increased apoptosis by TUNEL analysis and showed a significant decrease in cell proliferation, as determined by MIB-5 immunostaining. VT1 treatment of MM is effective in our orthotopic xenograft model, and warrants further exploration as a potential treatment for these highly anaplastic and aggressive neoplasms.

Abstract
Enzymes modulating local steroid availability play an important role in the progression of human breast cancer. These include isoforms of 17beta-hydroxysteroid dehydrogenase (17-HSD), aromatase and steroid sulphatase (STS). The aim of this study was to investigate the expression, by reverse transcription polymerase chain reaction, of 17-HSD types I-IV, aromatase and steroid STS in a series of 51 human breast tumour biopsies and 22 primary cultures of epithelial and stromal cells derived from these tumours, giving a profile of the steroid-regulating network for individual tumours. Correlations between enzyme expression profiles and expression of the interleukin (IL)-6 gene were also sought. All except one tumour expressed at least one isoform of 17-HSD, either alone or in combination with aromatase and STS. Expression of 17-HSD isoforms I-IV were observed in nine tumours. Of the 15 tumours which expressed three isoforms, a combination of 17-HSD II, III and IV was most common (6/15 samples). The majority of tumours (n = 17) expressed two isoforms of 17-HSD with combinations of 17-HSD II and IV predominant (7/17 samples). Eight tumours expressed a single isoform and of these, 17-HSD I was in the majority (5/8 samples). In primary epithelial cultures, enzyme expression was ranked: HSD I (86%) > STS (77%) > HSD II (59%) > HSD IV (50%) = aromatase (50%) > HSD III (32%). Incidence of enzyme expression was generally reduced in stromal cultures which were ranked: HSD I (68%) > STS (67%) > aromatase (48%) > HSD II (43%) > HSD IV (28%) > HSD III (19%). Expression of IL-6 was associated with tumours that expressed > or = 3 steroid-converting enzymes. These tumours were of higher grade and tended to come from patients with family history of breast cancer. In conclusion, we propose that these enzymes work in tandem with cytokines thereby providing sufficient quantities of bioactive oestrogen from less active precursors which stimulates tumour growth.

Abstract
OBJECT The goal of this study was to investigate whether the janus kinase/signal transducer and activator of transcription (JAK/STAT) signal transduction pathway is present and active in meningiomas. The results of these investigations are important for all meningioma therapies that, similar to interferon-alpha-2B (IFNalpha-2B), depend on activation of this pathway for their effect. The authors were interested in evaluating the importance, if any, of the JAK/STAT pathway in the biology and therapy for these tumors. METHODS Total proteins were extracted from 17 meningioma samples and the levels of JAKs and STATs were determined by using Western blot analysis. Levels of these proteins in meningiomas were compared with those found in normal dura. The JAKs and STATs (with the exception of Jak3 and Tyk2) were present both in the dura and in the meningiomas studied. In tumors JAK and STAT levels were always significantly higher than those found in normal dura. Differences in relative levels were found when meningiomas were subdivided according to the current neuropathological criteria and the highest levels were found in transitional meningiomas. The authors also investigated, using tyrosine-phosphorylated Statl and Stat3 antibodies, whether STATs were activated in meningiomas and normal dura in vivo. Their results indicate that both Statl and Stat3 are phosphorylated in vivo in meningiomas and in the dura. Furthermore, in vitro experiments in which two independent short-term cultures obtained from freshly dissected meningioma samples were used indicated that Statl and Stat3 are phosphorylated in response to treatment with IFNalpha-2B. Exposure of meningioma cells to IFNalpha-2B leads to nuclear translocation of tyrosine-phosphorylated Statl and Stat3, as demonstrated by immunocytochemical analysis. CONCLUSIONS The results of this study indicate that the JAK and STAT families of proteins are important effectors in brain tumors and support the idea that the effects of IFNalpha in vivo are direct and not mediated by the immune system. This suggests a role for modulation of STAT transcription factors in inhibiting meningioma cell proliferation.

Abstract
Interleukin-6 (IL-6) has been shown to be released by cultured human meningioma cells and may be a positive or negative regulator of tumour growth. IL-6 protein and mRNA levels have been examined in a series of meningiomas. In 14 cases, the results are compared with the effects of IL-6 and dexamethasone on growth and IL-6 secretion in vitro. Tumours with the highest in vivo IL-6 mRNA expression also showed maximum induction of IL-6 and increased cellular proliferation on IL-1 stimulation in vitro. Dexamethasone decreased the IL-1-stimulated IL-6 release in all cases. Meningiomas which had little or no IL-6 message were refractory to IL-1 control of IL-6. Remarkably, these formed the group of meningiomas that increased their growth rate in response to dexamethasone.
