background: glioma is the most common primary brain tumor with poor prognosis. temozolomide (tmz) has been used with irradiation (ir) to treat gliomas. the aim of the present study was to evaluate the cytotoxic and radiosensitizing effect of tmz when combined with high-dose and high-dose rate of gamma irradiation in vitro. methods: two ‘u87mg’ cell lines and skin fibroblast were cultured and as...

background and objectives: angiogenesis is essential for growth and metastasis of solid malignancies. tumor vessel count and expression of vascular endothelial growth factor (vegf), a potent angiogenic factor, have been associated with prognosis. this study was designed to assess vessels density by using cd31 and cd105 (endoglin) and their correlation with expression of vegf and proliferative i...

Glioblastoma is the most prevalent and malignant primary brain tumor in adults, and its response to current therapies is limited. Protein kinase CK2 is overexpressed in glioblastoma and regulates glioblastoma cell survival, proliferation, and migration and brain tumorigenesis. Targeting CK2 for glioblastoma treatment may benefit patients with glioblastoma.

Glioblastoma-initiating cells play crucial roles in the origin, growth, and recurrence of glioblastoma multiforme. The elimination of glioblastoma-initiating cells is believed to be a key strategy for achieving long-term survival of glioblastoma patients due to the highly resistant property of glioblastoma-initiating cells to temozolomide. Resveratrol, a naturally occurring polyphenol, has been...

glioblastoma is the most common and the most lethal primary brain cancer. this malignancy is highly locally invasive, rarely metastatic and resistant to current therapies. little is known about the distinct molecular biology of glioblastoma multiforme (gbm) in terms of initiation and progression. so far, several molecular mechanisms have been suggested to implicate in gbm development. homeodoma...

background: pattern recognition receptors (prrs) are the main sensors of pathogen and danger signals in innate immunity of which toll like receptors (tlrs) are the most studied ones. the contribution of prrs in cerebral inflammation induced by microbial infection, tissue damage and cancer has not extensively been addressed so far. glioma is the most common tumor of the central nervous system an...

radiation induced sarcoma is a rare but recognized complication of radiotherapy and is associated with poor prognosis, frequently occurs 5 years after completion of treatment. we report radiation-induced sarcoma in a 42 years old male, involving the left parietooccipital scalp region following treatment of brain tumor with craniotomy and post-operative radiation with 60co machine. diagnosis of ...

Glioblastoma multiforme is a deadly cancer whose current treatment options are limited. The ability of glioblastoma tumor cells to infiltrate the surrounding brain parenchyma critically limits the effectiveness of current treatments. We investigated how microglia, the resident macrophages of the brain, stimulate glioblastoma cell invasion. We first examined the ability of normal microglia from ...
