Gliomas, the most common form of brain tumour are characterised by a capacity to invade throughout normal brain tissue. This infiltrative nature is the hallmark of poor prognosis. A greater understanding of the molecular determinants that drive invasion may lead to improved therapy. Integrins are a large family of cell surface receptors that mediate(More)
Absence-like seizures in the Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model are believed to arise in hyperexcitable somatosensory cortical neurons, however the cellular basis of this increased excitability remains unknown. We have previously shown that expression of the Transmembrane AMPA receptor Regulatory Protein (TARP), stargazin, is(More)
OBJECTIVE To study the expression and function of the brain-specific proteinase deficient disintegrins, ADAM11 and ADAM22 (a disintegrin and metalloproteinase). METHODS Specimens of low- and high-grade gliomas and normal brain were analyzed for ADAM11 and ADAM22 expression using Western blotting. The effects of overexpression of ADAM11 and ADAM22 in(More)
The cyclic-AMP response element binding (CREB) protein has been shown to have a pivotal role in cell survival and cell proliferation. Transgenic rodent models have revealed a role for CREB in higher-order brain functions, such as memory and drug addiction behaviors. CREB overexpression in transgenic animals imparts oncogenic properties on cells in various(More)
OBJECTIVE To investigate the relationship of glutamate and glutamate transporter expression in human gliomas and surrounding peritumoral brain to the presence of tumor-associated seizures (TAS). METHODS We studied a retrospective (group 1: 190 patients) and then a prospective (group 2: 98 patients) cohort of patients who underwent a craniotomy for a(More)
Stargazin is membrane bound protein involved in trafficking, synapse anchoring and biophysical modulation of AMPA receptors. A quantitative trait locus in chromosome 7 containing the stargazin gene has been identified as controlling the frequency and duration of absence seizures in the Genetic Absence Epilepsy Rats from Strasbourg (GAERS). Furthermore,(More)
Accumulating evidence suggests that the stem cell markers CD133 and CD44 indicate molecular subtype in Glioblastoma Multiforme (GBM). Gene coexpression analysis of The Cancer Genome Atlas GBM dataset was undertaken to compare markers of the Glioblastoma Stem-Progenitor Cell (GSPC) phenotype. Pearson correlation identified genes coexpressed with stem cell(More)
We investigated the correlation between the circulating and imaging biomarkers of tumour vascularity, and examined whether they are prognostic of outcomes in patients with glioblastoma multiforme (GBM). Despite the increasing use of anti-angiogenic agents within neuro-oncology, there are still no validated biomarkers to monitor for a treatment response or(More)
The diffuse infiltrative nature of cerebral glioma is a primary reason for failure of current treatment regimes. An improved understanding of the molecular determinants of tumour invasion is imperative in order to achieve therapeutic advances. Integrin-linked kinase has been shown to be key in the regulation of cell migration, as well as proliferation and(More)
