tau is one of several types of microtubule-associated proteins (maps), responsible for the assembly and stability of microtubule networks that is present only in neurons and predominantly localized in axons which its functions are tightly regulated by phosphorylation. via as yet unknown mechanisms, tau becomes hyperphosphorylated and accompanies with neuronal degeneration, loss of synapses, abe...

Phosphorylation is a posttranslational modification of proteins that regulates many biological functions, such as development, morphogenesis, gene expression, metabolism and neuronal activity. Dysregulation phosphorylation causes diseases including cancer Alzheimer’s disease. Then, lot research has been performed to reveal the molecular mechanism phosphorylation; identification site(s), protein...

Myocardial infarction and cerebral ischemic stroke are prominent causes of death worldwide. Platelets play major roles in these diseases, although they anucleated cells, but also express the NF-?B. Pterostilbene (PTE) possesses some intriguing pharmacological properties, including capacity to inhibit platelet activation. We investigated inhibitory role PTE NF-?B-mediated signal events compared ...

Antiproliferative protein (APP) isolated from conditioned media of two androgen-independent prostatic carcinoma cell lines, PC3 and Du-145 was shown to inhibit selectively cell proliferation of androgen-dependent prostate cancer cell line LNCaP in a dose dependent manner. This protein was further purified with HPLC using hydrophobic interaction column (phenyl 5PW) and was used to study the modu...

Intraplatelet phospho-VASP analysis is a commonly used approach for monitoring of anti-platelet therapy; however, testing of intraplatelet phospho-VASP expression needs a high level of experience and proficiency. The ability to recognize how the pre-analytical variations can change the results would be helpful for the interpretation of data from intraplatelet P-VASP analysis. The aim of this st...

Background and objectives: Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) inhibition results in an increase in apoptosis. It has been demonstrated that NF-κB subunit p65 phosphorylation at the IκB kinase phosphorylation site serine 536 (Ser536) is essential for the NF-κB nuclear translocation and activation. Therefore, NF-κB can be downregulated by suppressing its phosph...

ige-mediated cell signaling, induced by cross-linking of high affinity receptor for ige (fcεri) in the presence of antigen (ag), is a well known mechanism described for mast cell activation in allergy and hypersensitivity reactions, which induces a spectrum of cellular responses such as secretion and up-regulation of cell surface fcεri. although for several years  ige  binding  to  fcεri  was  ...

Abstract Lysosomes are dynamic organelles that transported along microtubules bidirectionally via kinesin and dynein motor proteins. Lysosomal positioning, which is determined by the balance of bidirectional lysosomal movement, changes under various conditions affects functions such as autophagy antigen presentation. A recent study Takemasu et al. (Phosphorylation TMEM55B Erk/MAPK regulates pos...
