Malignant gliomas are locally aggressive, highly vascular tumors that have a dismal prognosis, and present therapies provide little improvement in the disease course and outcome. Many types of malignancies, including glioblastoma, originate from a population of cancer stem cells (CSCs) that are able to initiate and maintain tumors. Although CSCs only… (More)
Malignant glioblastoma (GBM) is a highly aggressive brain tumor with a dismal prognosis and limited therapeutic options. Genomic profiling of GBM samples has identified four molecular subtypes (Proneural, Neural, Classical and Mesenchymal), which may arise from different glioblastoma stem-like cell (GSC) populations. We previously showed that adherent… (More)
Ionizing radiation (IR) is an essential component of therapy for alveolar rhabdomyosarcoma. Nuclear factor-kappaB (NF-κΒ) transcription factors are upregulated by IR and have been implicated in radioresistance. We evaluated the ability of curcumin, a putative NF-κΒ inhibitor, and cells expressing genetic NF- κΒ inhibitors (IκBα and p100 super-repressor… (More)
The nuclear factor-kappa B (NFκB) signal transduction pathway plays an important role in immunity, inflammation, cell growth, and survival. Since dysregulation of this pathway results in high, constitutive NFκB activation in various cancers and immune disorders, the development of specific drugs to target this pathway has become a focus for treating these… (More)
The use of tetraspanin CD9 as a biomarker for renal cell carcinomas (RCC) has been explored with minor conclusions. Identification of a biomarker that not only distinguishes between the different types of renal cell carcinomas, but also predicts the metastatic potential of these tumors would significantly advance diagnosis and prognosis of kidney cancers.… (More)
