Glioblastoma (GBM) patients suffer from a dismal prognosis, with standard of care therapy inevitably leading to therapy-resistant recurrent tumors. The presence cancer stem cells (CSCs) drives the extensive heterogeneity seen in GBM, prompting need for novel therapies specifically targeting this subset tumor-driving cells. Here, we identify CD70 as potential therapeutic target GBM CSCs.
Abstract Medulloblastoma is the most common malignant brain tumor in children. This disease heterogeneous and composed of four subtypes medulloblastoma [WNT, Sonic Hedgehog (SHH), Group 3, 4]. An immediate goal to identify novel molecular targets for aggressive forms medulloblastoma. Polo-like kinase 1 (PLK1) an oncogenic that controls cell cycle proliferation, making it a strong candidate treatment. In this study, pediatric medulloblastomas were subtyped two patient cohorts (discovery...
The Y-box binding protein 1 (YB-1) is upregulated in many human malignancies including glioblastoma (GBM). It also essential for normal brain development, suggesting that YB-1 part of a neural stem cell (NSC) network. Here, we show was highly expressed the subventricular zone (SVZ) mouse fetal tissues but not terminally differentiated primary astrocytes. Conversely, knockout mice had reduced Sox-2, nestin, and musashi-1 expression SVZ. Although murine neurospheres were rich YB-1, its lost...
In this manuscript, we use genetic data to provide a three-faceted analysis on the links between molecular subclasses of glioblastoma, epithelial-to-mesenchymal transition (EMT) and CD133 cell surface protein. The contribution paper is three-fold: First, newly identified signature for in human mammary epithelial cells, demonstrate that genes have significant overlap with differentially expressed all known GBM subtypes. However, up regulated mesenchymal subtype EMT was more than other Second,...
Background. Few protocols exist for returning children/youth to school after concussion. Childhood concussion can significantly affect performance, which is vital social development, academic learning, and preparation future roles. The goal of this knowledge translation research was develop evidence based materials inform physicians about pediatric Methods. Return School (RTS) protocol developed following the National Institute Health Care Excellence procedures. Results. Based on a scoping...
The reported risk factors for glioblastoma (GBM), i.e., ionizing radiation, Li-Fraumeni syndrome, Neurofibromatosis I, and Turcot also increase the of other brain tumor types. Risk human GBM are associated with different oncogenic mutation profiles. Pedigreed domestic dogs a shorter nose flatter face (brachycephalic dogs) display relatively high rates glioma formation. genetic profiles canine gliomas idiosyncratic. association putatively mutational patterns in humans canines suggests that...
Glioblastoma multiforme (GBM) ranks among the deadliest types of cancer and given these new therapies are urgently needed. To identify molecular targets, we queried a microarray profiling 467 human GBMs discovered that polo-like kinase 1 (PLK1) was highly expressed in tumors it clustered with proliferative subtype. Patients PLK1-high were more likely to die from their disease suggesting current inactive against such tumors. This prompted us examine its expression brain tumor initiating cells...
