objective(s): acquisition of tnf-α resistance plays role in the onset and growth of malignant tumors. previous studies have demonstrated that mcf-7 cell line and its doxorubicin resistant variant mcf-7/adr are resistant against the cytotoxic effects of tnf-α. in this study, we investigated the role of akt activation in resistance of mcf-7 and mcf-7/adr against tnf-α cytotoxicity. materials and ...

conclusions in the chinese han population that we studied, nafld patients who carry the tnf-α-238 ga polymorphism have an increased risk of developing cad. mechanisms underlying this potentially important association require further investigation. background cardiovascular events account for the main cause of death in patients with non-alcoholic fatty liver disease (nafld), and are largely infl...

background: bone resorption is one of the main features of inflammatory periapical lesions and is mainly mediated by interleukin-1 beta (il-1β), tumor necrosis factoralpha (tnf-α) and prostaglandin-e2 (pge2). recent investigations of these lesions revealed that pharmacological modulation may be possible. objective: the aim of this study was to evaluate the effect of ibuprofen on il-1β, tnf-α an...

many species of tea (camellia sinensis) and cowslip (echium amoenum) are used in iranian traditional medicine. the aim of this study was to conduct the survey on the ability of iranian black tea and cowslip extracts on secretion of tumor necrosis factor-alpha (tnf-alpha) by non-infected and infected mouse macrophages. a macrophage infection model with legionella pneumophila and enzyme linked im...

Antibody agonists targeting tumor necrosis factor (TNF) superfamily receptors, including CD40, are being tested therapeutically as anticancer agents. Studies in mice have shown that anti-CD40 monoclonal antibody (mAb) requires Fc-receptor (FcR) engagement to activate antitumor immunity. In contrast, we have reported that clinically active anti-human CD40 mAb CP-870,893 does not require FcR cros...

Recently we have identified a novel protein NIP45 (nuclear factor of activated T cells [NFAT]-interacting protein) which substantially augments interleukin (IL)-4 gene transcription. The provision of NIP45 together with NFAT and the T helper cell type 2 (Th2)-specific transcription factor c-Maf to cells normally refractory to IL-4 production, such as B cells or Th1 clones, results in substantia...
