background and objective: the management of apoptotic cell death has been considered as a putative therapeutic strategy for cancer treatment. in the present study we investigated the putative pro-apoptotic effect of allicin, the main garlic organosulfur component with repeatedly claimed chemopreventive potency, on the human adenocarcinoma cell line ht29 as an apoptosis resistant cell line, in v...

background: pattern recognition receptors (prrs) are the main sensors of pathogen and danger signals in innate immunity of which toll like receptors (tlrs) are the most studied ones. the contribution of prrs in cerebral inflammation induced by microbial infection, tissue damage and cancer has not extensively been addressed so far. glioma is the most common tumor of the central nervous system an...

background: interfering with cell proliferation and survival is a critical role for antineoplastic drugs leading to cell death through induction of apoptosis. alternative treatments with herbal extracts offer insights into acute myeloid leukemia (aml) therapy. parthenolide (ptl), an extract from feverfew, induces apoptosis in primary human leukemia stem cells (lscs) and bulk leukemic cell popul...

objective: nucleostemin (ns) is a recently identified gene that is expressed mainly in the nucleoli of neuronal, embryonic and mesenchymal stem cells which plays a role in their self renewal. over expression of this gene has been reported in several cancer cell lines tumoral tissues including gastric, hepatic and prostate cancer. in this study, we investigated the effects of suppression of this...

background : the development of chemoresistance represents a major obstacle in the successful treatment of cancers such as non-hodgkin’s lymphoma (nhl). with the recognition of important roles for both p53 and its more recently described paralog p73 in mediating the activity of anti-cancer drugs, there has been increasing recognition that cellular resistance to anthracyclines could and does a...

The reports show that rutin has good potentials as an anticancer agent; however, poor bioavailability due to its low aqueous solubility. present study was aimed at preparing and evaluating physicochemical properties well the activities of nanocrystals (RNs). RNs were prepared via ultrasonication method. then physicochemically characterized by conventional techniques. cytotoxic effect free on HN...

background: adipose tissue has characteristics of an endocrine organ which releases a number of adipocyte-specific factors, known as adipocytokines.  it has recently suggested that adipocytokines might play a role in pathogenesis and progression of certain cancers, especially in gastric cancer.  this study has managed to investigate endogenous and/or exogenous expression of visfatin and resisti...

background: mehr-80 is a newly established adherent human large cell lung cancer cell line that has not been transfected until now. this study aims to define the optimal transfection conditions and effects of some critical elements for enhancing gene delivery to this cell line by utilizing different non-viral transfection procedures. methods: in the current study, calcium phosphate (cap), deae-...

many cell lines, when cultured under proper conditions, can form three dimensionalstructures called multicellular spheroids. these spheroids resemble in vivo tumor models in severalaspects. therefore, studying growth characteristics and behavior of spheroids is beneficial inunderstanding the behavior of tumors under various experimental conditions. in this work, we havestudied the growth proper...
