Involvement of epimutations in meningioma
Abstract Epimutations are heritable and reversible cell markers, which can influence cell function going beyond the effects of DNA mutations. They result from multiple and coordinated mechanisms able to modulate gene expression. Regarding the significance of epigenetics in meningioma, few and somehow contradictory results are available, although promising information has been obtained. Here we highlight the most recent advances about the impact of DNA methylation, histone modifications, and microRNA regulation on meningioma development as well as the interplay between genetic and epigenetic alterations. Data indicate that epigenetics can help to identify novel candidate genes for the management and treatment of meningioma.
In conclusion, our results demonstrated that compression induced apoptosis in primary cultured cortical neurons, which was associated with ROS mediated ER stress and mitochondrial dysfunction. Pharmacological compounds or agents targeting mitochondrial dysfunction and ER stress associated oxidative stress might be ideal candidates for the treatment of IH-related neurological diseases.
In conclusion, quantitative evaluation of the performance of the method proved its improved accuracy compared to other current state-of-art techniques, and it showed robust performance even with noise and a narrow overlapping region between adjacent fields.
Gliomas comprise approximately 30% of all primary brain tumors (BTs). Glioblastoma multiforme (GBM) accounts for more than half of all gliomas and is a highly malignant form of brain cancer with a 5-year survival rate of
Conclusion The current meta-analysis showed the good sensitivity and specificity of radiolabeled amino acid PET for detection of PsP of brain tumor after treatment. Also, the DOR was high and SROC curve showed high AUC value.
This study concludes that the newly produced Cm-Au-PLGA-PSPE composite would be a promising alternative in treating human gliomas and associated wounds with increased biomedical applications. PMID: 31411066 [PubMed - in process]
AbstractThe brain tumours represent a complex tissue that has its own characteristic metabolic features and is interfaced with the whole organism. We investigated changes in basal blood plasma metabolites in the presence of primary brain tumour, their correlation with tumour grade, as well as the feasibility of statistical discrimination based on plasma metabolites. Together 60 plasma samples from patients with clinically defined glioblastoma, meningioma, oligodendrioglioma, astrocytoma, and non ‐specific glial tumour and plasma samples from 28 healthy volunteers without any cancer history were measured by NMR spectrosco...
Conclusions: The model can efficiently highlight the “tumor” with 3 different colors—green, yellow, or infrared green with color overlay. These models showed high face and content validity, although there was no significant difference among the models regarding the degree of simulation and training effectiveness.
AbstractTumour progression involves interactions among various cancer cell clones, including the cancer stem cell subpopulation and exogenous cellular components, termed cancer stromal cells. The latter include a plethora of tumour infiltrating immunocompetent cells, among which are also immuno-modulatory mesenchymal stem cells, which by vigorous migration to growing tumours and susequent transdifferentiation into various types of tumour-residing stromal cells, may either inhibit or support tumour progression. In the light of the scarce therapeutic options existing for the most malignant brain tumour glioblastoma, mesenchy...
This article provides a brief discussion of the major 2016 updates to the WHO CNS classification scheme and reviews typical MR imaging findings of adult primary CNS neoplasms, including diffuse infiltrating gliomas, ependymal tumors, neuronal/glioneuronal tumors, pineal gland tumors, meningiomas, nerve sheath tumors, solitary fibrous tumors, and lymphoma.
ConclusionsPostoperative ES was diagnosed in 4.9% of patients after brain tumor surgery, and NCSE constituted the overwhelming majority of postoperative ES.
