زمینه و هدف: با توجه به شیوع بالایی سرطان کلون در جوامع انسانی و از جمله ایران، هدف این مطالعه شناسایی مولکولی و بررسی اثر سایتوتاکسیک باکتری پروبیوتیک کشته شده توسط حرارت و القا آپوپتوز بر رده سلولی HT-29 سرطان کلون و مقایسه آن با رده سلولی نرمال میباشد. مواد و روش ها: شناسایی مولکولی باکتری بومی جدا شده از دوغ ترخینه (TD4) انجام شد. دو رده سلولی HT-29 و HEK-293 تحت تاثیررقتهای 00/01، 0/1، 1...
Kcv (K(+) Chlorella virus) is a miniature virus-encoded K(+) channel. Its predicted membrane-pore-membrane structure lacks a cytoplasmic C-terminus and it has a short 12 amino acid (aa) cytoplasmic N-terminus. Kcv forms a functional channel when expressed in human HEK 293 cells. Deletion of the 14 N-terminal aa results in no apparent differences in the subcellular location and expression level ...
background: ferroportin (fpn), a regulator of iron homeostasis is a conserved membrane protein that exports iron across the enterocytes, macrophages and hepatocytes into the blood circulation. fpn has also critical influence on survival of microorganisms whose growth is dependent upon iron, thus preparation of fpn is needed to study the role of iron in immunity and pathogenesis of micoorganisms...
Overexpression of efflux transporters, in human cells, is a mechanism of resistance to drug and also to chemotherapy. We found that multidrug resistance protein-4 (MRP4) overexpression has a role in reducing aspirin action in patients after bypass surgery and, very recently, we found that aspirin enhances platelet MRP4 levels through peroxisome proliferator activated receptor-α (PPARα). In the ...
The Na(+)/H(+) exchanger regulatory factor (NHERF) is constitutively phosphorylated in cells, but the site(s) of this phosphorylation and the kinase(s) responsible for it have not been identified. We show here that the primary site of constitutive NHERF phosphorylation in human embryonic kidney 293 (HEK-293) cells is Ser(289), and that the stoichiometry of phosphorylation is near 1 mol/mol. NHE...
The corticotropin-releasing factor (CRF) receptor 1 (CRFR1) is a target for the treatment of psychiatric diseases such as depression, schizophrenia, anxiety disorder, and bipolar disorder. The carboxyl-terminal tail of the CRFR1 terminates in a PDZ-binding motif that provides a potential site for the interaction of PSD-95/Discs Large/Zona Occludens 1 (PDZ) domain-containing proteins. In this st...
Myricetin (Myr) is a f lavonoid that exerts anti-arrhythmic effects. However, its potential effects on ion channels have remained elusive. The aim of the present study was to investigate the effects of Myr on Kv1.5 channels in HEK293 cells. The current of Kv1.5 channels (Ikur) in HEK293 cells was recorded using the whole-cell patch-clamp technique and the expression of the Kv1.5 protein was mea...
Gain/loss of function studies were utilized to assess the potential role of the endogenous vanilloid receptor TRPV4 as a sensor of flow and osmolality in M-1 collecting duct cells (CCD). TRPV4 mRNA and protein were detectable in M-1 cells and stably transfected HEK-293 cells, where the protein occurred as a glycosylated doublet on Western blots. Immunofluorescence imaging demonstrated expressio...
