objective(s):intermittent hypoxia (ih), caused by obstructive sleep apnea (osa), could cause hippocampus or neuron damage through multiple signaling pathways, while the underlying mechanisms are still unclear. thus, the present study aimed to explore the effect of ih on the biological functions of microglia cells. materials and methods:cell proliferation of bv2 cells after exposure to ih were o...

neurological inflammatory diseases are developing rapidly. different factors involved in the pathogenesis of these diseases. in this article, we discuss some of the mechanisms are dealt with. an aberrant procedure of beta-amyloid precursor protein (bapp) to form neurotoxic beta-amyloid peptides and an accumulated insoluble polymer of beta –amyloid (ba) that forms the senile plaque. the above pr...

objective: different signaling pathways have been identified that are involved in the cellular response to opiates. the mitogen-activated protein kinase pathway is one of the most important signaling pathways underlying the neuronal response to opiates. micrornas (mirnas) are considered to be post-transcriptional regulators of gene expression with paramount significance, which plays key roles i...

backgroud: protein-protein interaction, plays a key role in signal transduction in signaling pathways. different approaches are used for prediction of these interactions including experimental and computational approaches. in conventional node-edge protein-protein interaction networks, we can only see which proteins interact but ‘structural networks’ show us how these proteins interact which ca...

low glucose condition induces neuronal cell-death via intracellular mechanisms including mitogen-activated protein kinases (mapk) signaling pathways. it has been shown that low glucose medium decreases neuronal survival in cerebellar granule neurons (cgns). in this study, we have examined the activation of jnk, p38kinase and erk1/2 pathways in low glucose medium in cgns. the cgns were prepared ...

introduction: carbon nanotubes (cnts) have shown enormous potential in neuroscience. nerve growth factor (ngf)-cnts complex promotes the neuronal growth, however, the underlying mechanism(s) have remained elusive. based on the interplay between ngf and the endocannabinoid system, involvement of the neuroprotective endocannabinoid, 2-arachidonoyl glycerol (2-ag), was investigated in the mechanis...

background and objectives: silymarin is a unique flavonoid complex with documented hepatoprotective properties. silybum  marianum hairy root culture as a source for producing silymarin has been an important strategy for study the cell signaling pathway. in the present investigation trichoderma strains- silybum marianum hairy root cultures interactions have been studied. methods: the effects of ...

introduction: atherosclerosis, hypertension, ischemic diseases, alzheimer’s disease, parkinson disease, cancer and inflammation emerge from imbalance between antioxidant and oxidants. cancer is a most important public health problem in both developed and developing countries. natural antioxidants such as polyphenols are being used for prevention and treatment cancer. polyphenols include phenoli...

background: coronary artery disease (cad) is the major cause of mortality and morbidity worldwide. the aim of this study was to explore the effect of resveratrol (res) on canonical β-catenin/wnt and forkhead box o (foxo) pathways in cad patients.method: we performed this study on 10 metabolic syndrome patients with three-vessel cad and 10 sex-aged matched healthy subjects. the effects of res on...

traumatic brain injury (tbi) results from a sudden and external physical impact to the head, and often leads to motor and cognitive impairment. using tissue engineering strategies, we aimed to review aspects of extra cellular matrix (ecm) based scaffold that could be delivered to the injured brain. the ecm is produced intracellularly and secreted to form a dense network of proteins and glycans,...
