CCR Grand Rounds Dr. Jabado ’ s research focuses on elucidating genetic signatures of pediatric astrocytomas and examining how they compare to adults. These are deadly brain tumors that originate in the brain and include glioblastomas (GBM, the highest grade of astrocytomas), which are one of the deadliest cancers in humans. Her group uncovered that pediatric high-grade astrocytomas (HGA) are molecularly and genetically distinct from adult tumors. They also identified a new molecular mechanism driving pediatric HGA, namely recurrent somatic driver mutations in the tail of histone 3 variants (H3.3 and H3.1). These mut...

Conclusions. In summary, RES529, the first dual TORC1/TORC2 dissociative inhibitor, lacking affinity for ABCB1/ABCG2 and having good brain penetration, was active in GBM preclinical/murine models giving credence to its use in clinical trial for patients with GBM treated in association with anti-angiogenetic compounds.

We measured the resting-state functional connectivity of 126 patients with left cerebral gliomas involving language network areas, including 77 patients with low-grade glioma (LGG) and 49 patients with high-grade glioma (HGG). Functional network mapping for language was performed by construction of ...

Parents of Abbie Mifsud created the charity that has funded vital research on brain stem tumoursResearchers say they are close to testing a drug that could tackle a previously untreatable childhood brain cancer. The condition is known as DIPG – diffuse intrinsic pontine glioma – and every year it affects between 30 to 40 boys and girls, aged between five and 10. All develop tumours caused by the condition and die, often within months of their diagnoses.But now scientists believe they may soon be able to tackle the condition – and one of the key organisations involved is a remarkable charity set up by Aman...

Authors: Suo F, Zhong B, Lu F, Dong Z Abstract Glioma is the most aggressive brain tumor and is associated with a high mortality rate. The aim of the present study was to explore the association between matrix metalloproteinase 2 (MMP-2) and ephrin type-A receptor 2 (EphA2) expression in glioma cells, and to investigate the contribution of magnetic resonance imaging (MRI) in glioma classification. A total of 43 patients with pathologically confirmed glioma were divided into two groups as follows: Low-grade (grades I and II; n=21) and high-grade (grades IV and IV; n=22). Subsequently, immunohistochemistry staining w...

Purpose Gliomas constitute the most frequent primary brain tumors. Glioblastoma, the most common and malignant glioma in adults, has dismal prognosis with any current therapy. On the other hand, low-grade gliomas, the second most common type of gliomas, are potentially curative with appropriate treatment. Methods We conducted a meta-analysis to assess the performance of PET tracers with the best available evidence, namely, fluorodeoxyglucose (FDG), 11C-methionine (MET), and 18F-fluoroethyltyrosine (FET), in differentiating low- from high-grade gliomas. Results Twenty-three studies with a total of 994 participants w...

Publication date: Available online 16 October 2019Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Deborah Piffaretti, Floriana Burgio, Marcus Thelen, Alain Kaelin-Lang, Paolo Paganetti, Michael Reinert, Maria Luisa D'AngeloAbstractFluorescence image guided surgical resection (FIGR) of high grade gliomas (HGGs) takes advantage of the accumulation of the tracer protoporphyrin IX (PpIX) in glioma cells following administration of 5-aminolevulinic acid (5-ALA). Occasionally, PpIX fluorescence intensity may be insufficient, thus compromising the efficacy and precision of the surgical intervention. The ca...

The objective of this paper was to obtain monitored tumor-targeted therapeutic nanoparticles (NPs). To that end, theranostic surfactant-coated polymer poly-Lactic-co-Glycolic Acid (PLGA) nanoplatform encapsulating doxorubicin hydrochloride (DOX) and superparamagnetic iron oxide NPs (SPIONs) were developed. Different non-ionic surfactants known as BBB crossing enhancers (Tween 80, Brij-35, Pluronic F68 or Vitamin E-TPGS) were used to develop 4 types of theranostic nanoplatforms, which were characterized in terms of size and morphology by DLS, TEM and STEM-HAADF analyses. Moreover, the 3-month stability test, the therapeutic...
