Introduction: Malignant astrocytic gliomas are the most common and lethal brain malignancies due to their refractory to the current therapies. Nowadays, molecular targeted therapy has attracted great attention in treatment of glioma. Connexin 43 (Cx43) and micro ribonucleic acid- 21(miR-21) are among molecules that are involved in glioma development and progression. These molecules showed...

Introduction: There are evidences showing the role of nitric oxide in the opiate reward properties. The role of nitric oxide signaling pathway as an intracellular mechanism on augmentation of long term potentiation in hippocampal CA1 area of rats is also confirmed. It has been also reported that oral morphine dependence facilitates formation of spatial learning and memory via activation of N...

Introduction: The neuroprotective impact of curcumin and the role of CREB (cyclic AMP response element binding protein)-BDNF (brain-derived neurotrophic factor) signaling pathway was evaluated in methamphetamine (METH)-induced neurodegeneration in rats. Methods: Sixty adult male rats were randomly divided into 6 groups. While normal saline and 10 mg/kg METH were administered intraperitoneally ...

acute myeloblastic leukemia is the most frequent cancer in adults and the patients have a wide range of sub-classes. hla dr negative cases represent one of the major immune-phenotypic classes.  hla-dr is routinely used to distinguish acute promyelocytic leukemia (apl) from other aml subclasses based on the immunophenotype. the tgf-b signaling pathway, as a critical regulator, guides different v...

Objective(s): Fibromyalgia (FM) is a central nervous system disorder characterized by widespread mechanical hyperalgesia due to unknown mechanisms. Several inflammatory mediators, such as interleukin-1 (IL-1), IL-6, IL-8, and tumor necrosis factor, are increased in the serum of FM patients. Although medications including pregabalin, duloxetine, and milnacipran are used...

Objective(s): To investigate the effect of Ginkgo biloba extract EGb761 in early brain injury (EBI) after subarachnoid hemorrhage (SAH) and its mechanism. Materials and Methods: The SAH rat model was constructed and pre-treated with EGb761.The neurological function, severity of SAH, water content of brain tissue, damage degree of the blo...

atherosclerosis has serious role in coronary arteries disease,so it is important to establish effective strategies for prevention or even treatment of atherosclerosis. adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. disturbed adiponectin actions through its receptor, (adipor1 and adipor2) may be involved in atheros...

Background: Transforming growth factor-β (TGF-β) in addition to the C-terminal region can phosphorylate receptor-regulated Smads (R-Smads) in their linker region. The aim of the present study was to evaluate the role of signaling mediators such as NAD(P)H oxidases (reactive oxygen species [ROS] generators), ROS, and ROS-sensitive p38 mitogen-activated protein kinase (p38MAPK) in this signaling ...
