The TPR proteins FKBP52, FKBP51, Cyp40, and PP5 are found in steroid receptor (SR) complexes, but their receptor-specific preferences and roles remain unresolved. We have undertaken a systematic approach to this problem by examining the contribution of all four TPRs to the localization properties of glucocorticoid (GR) and progesterone (PR) receptors. The GR of L929 cells was found in the cytop...

A combination of tumor necrosis factor (TNF) and the topoisomerase I inhibitor, camptothecin, or the topoisomerase II inhibitors, teniposide and amsacrine, produced dose-dependent synergistic cytotoxicity against the murine L929 fibrosarcoma cells. Similar synergy was not observed with a combination of TNF and bleomycin. To define the role of TNF in the augmentation of tumor cell killing by top...

وقایع استرس زا می توانند تغییراتی را در سیستم های ایمنی، درون ریز، قلبی-عروقی و عصبی ایجاد نموده و به این ترتیب پاسخ استرس را بوجود آورند. استرس ممکن است در تغییر قابلیت و عملکرد سلول ها نقش داشته و بنابراین در ایجاد بیماری ها درگیر باشد. چنین تغییراتی ممکن است باعث القاء آسیب dna شده و یا قابلیت سلول ها برای پاسخ به آن ها را تحت تأثیر قرار دهند. آسیب dna که بوسیله استرس القاء می شود، یک مکانیس...

The existence of reliable mtDNA reference sequences for each species is of great relevance in a variety of fields, from phylogenetic and population genetics studies to pathogenetic determination of mtDNA variants in humans or in animal models of mtDNA-linked diseases. We present compelling evidence for the existence of sequencing errors on the current mouse mtDNA reference sequence. This includ...

INTRODUCTION Silver nanoparticles have been used for different purposes in dentistry, including endodontic treatments. The aim of this study was to determine the cytotoxicity of different types of silver nanoparticles on mouse fibroblast cell line L929 and the reaction of subcutaneous connective tissue of Wistar rats to these nanoparticles. METHODS Silver nanoparticles of an average size of 5...

We have previously shown that lactoperoxidase (LPO) covalently coupled to polystyrene tissue culture flasks can be used to radioiodinate monolayer cell proteins that come into intimate contact with the LPO-polystyrene surface. These studies have now been extended to include a detailed examination of the class of iodinated polypeptides migrating with apparent molecular weights of 50,000 and 55,0...

The release of tumor necrosis factor α (TNF-α) by ochratoxin A (OTA) was studied in various macrophage and non-macrophage cell lines and compared with E. coli lipopolysaccharide (LPS) as a standard TNF-α release agent. Cells were exposed either to 0, 2.5 or 12.5 µmol/L OTA, or to 0.1 µg/mL LPS, for up to 24 h. OTA at 2.5 µmol/L and LPS at 0.1 µg/mL were not toxic to the tested cells as indicate...

Cell aggregates have been applied in various fields such as regenerative medicine and drug toxicity testing. We shown that H-(Lys-Pro)12-OH (KP24), a repeating sequence of lysine (Lys) proline (Pro), induces uniformly sized cell simply by its presence suspension. In this study, we considered peptide could be to three-dimensional culture substrate can induce uniform immobilizing it on the substr...
