Tumor Metabolism of Malignant Gliomas
Constitutively activated oncogenic signaling via genetic mutations such as in the EGFR/PI3K/Akt and Ras/RAF/MEK pathways has been recognized as a major driver for tumorigenesis in most cancers. Recent insights into tumor metabolism have further revealed that oncogenic signaling pathways directly promote metabolic reprogramming to upregulate biosynthesis of lipids, carbohydrates, protein, DNA an...
متن کاملThe role of cancer stem cells (CD133(+)) in malignant gliomas.
Malignant gliomas, particularly glioblastoma multiforme (GBM) tumors, are very difficult to treat by conventional approaches. Although most of the tumor mass can be removed by surgical resection, radiotherapy, and chemotherapy, it eventually recurs. There is growing evidence that cancer stem cells (CSCs) play an important role in tumor recurrence. These stem cells are radioresistant and chemore...
متن کاملAn overview of therapeutic approaches to brain tumor stem cells
Primary and secondary malignant central nervous system (CNS) tumors are devastating invasive tumors able to give rise to many kinds of differentiated tumor cells. Glioblastoma multiform (GBM), is the most malignant brain tumor, in which its growth and persistence depend on cancer stem cells with enhanced DNA damage repair program that also induces recurrence and resists current chemo- and radi...
متن کاملSURVIVAL IN PATIENTS WITH MALIGNANT GLIOMAS OF THE BRAIN
The present retrospective study was designed to analyze factors with prognostic values a) within, and b) significantly associated with, short-term (12months or less) and long-term (more than 24 months) survival times, i n 72 consecutive patients treated for malignant gliomas. Among 41 (57%) short-term surviving patients, the absence of both aphasia and motor deficit (as initial presenting ...
متن کاملTreatment Resistance Mechanisms of Malignant Glioma Tumor Stem Cells
Malignant gliomas are highly lethal because of their resistance to conventional treatments. Recent evidence suggests that a minor subpopulation of cells with stem cell properties reside within these tumors. These tumor stem cells are more resistant to radiation and chemotherapies than their counterpart differentiated tumor cells and may underlie the persistence and recurrence of tumors followin...
