egfr is a key molecule in cancer cells. egfr signaling was shown to promote tumor cell proliferation and survival, invasion and angiogenesis and mediate resistance to treatment, including ionizing radiation in preclinical models. we extracted proteins from astrocytoma (iii and iv) oligodendroglioma(iv) tumors and normal brain tissues and then evaluated the protein purity by bradford test and sp...

Background& Objective: Micro-vascular proliferation is an important histological feature of brain glioma with more vascular proliferation is present in higher grades of glioma. CD 105 is expressed in new actively proliferating and immature endothelial cells in tumor environment  and appears to be capable to distinguish between malignant neo-vasculature and normal vesse...

To investigate the effects of the two-pore-domain potassium (K2P) channel TASK-3 in a syngeneic murine model for malignant glioma. Malignant or high-grade glioma (WHO grade III and IV) are the most common and most aggressive primary brain tumors in adults. Despite aggressive multimodal therapy, the outcome of patients with malignant glioma remains poor. However, recent phase I and II trials hav...

mirnas are endogenous small noncoding rnas that can regulate many cellular processes. different expression levels of several mirnas have been detected in glioblastomas. function of mirnas and targets have been well studied in recent years. according to these studies, the role of mirnas in glioblastoma pathogenesis have been defined. mirnas have affected many processes in gbm such as apoptosis, ...

Objective(s): 18F-fluciclovine (trans-1-amino-3-[18F] fluorocyclobutanecarboxylic acid, [FACBC]) is an artificial amino acid radiotracer used for positron emission tomography (PET) studies, which is metabolically stable in vivo and has a long half-life. It has already been shown that FACBC-PET is useful for glioma imaging. However, there have been no reports evaluating the efficiency of FACBC-P...

Introduction: Glioma is the most common type of brain malignancy among adults. Treatment for this type of tumor involves surgery, radiotherapy, and in higher grades, including chemotherapy. The precise grading of the tumor is critical for treatment planning and prognosis determining. Considering the possibility of problems such as errors in tissue sampling during surgery, as we...

Glioma, as a primary tumor of central nervous system, is the main cause of death in patients with brain cancer. Therefore, development of an efficient strategy for treatment of glioma is worthy. The aim of the current study was to develop a SRL peptide-coated dendrimer as a novel dual gene delivery system for targeting the LRP receptor, an up-regulated gene in both BBB and glioma cells. To perf...

TASK-3, a two-pore-domain (K2P) potassium channel, has been implicated as important regulator for the effector function and proliferation of T-cells. Interestingly, TASK-3 has also a functional impact on tumor cells. Therefore, we sought to investigate whether TASK3 modulation might have a therapeutic potential for malignant gliomas by a variety of phenotypical and functional in vitro assays mi...

objective(s)progesterone is a steroid hormone whose biology has been greatly studied within the confines of reproductive function. in recent years, the neuroprotective effects of progesterone have attracted growing interest. glial cell line-derived neurotrophic factor (gdnf), is a neurotrophic factor which plays a crucial role in the development and maintenance of distinct sets of central and p...
