background & objectives: chronicity of lupus nephritis (ln) should be considered for interaction of cell mediated immunity (cmi) and dendritic cells in glomeruli and tubulointerstitial areas. in this study establishment of immunohistopathological changes of dendritic cells and other immune effector cells in lupus nephritis comparing with non-lupus nephritis was performed. materials & m...

 Caffeic acid phenethyl ester(CAPE) suppresses the growth of transformed cells such as human breast cancer cells, hepatocarcinoma , myeloid leukemia, colorectal cancer cells, fibrosarcoma, glioma and melanoma. A group of heterocyclic esters of caffeic acid was synthesized using Mitsunobu reaction and the esters were subjected to further structural modification by electrooxidation of the catecho...

objective(s) the cytotoxic effects of crude ethanol extracts of some previously tested iranian conifers  on tumor cell lines have motivated us to screen different parts of two subspecies in these genus. materials and methods terminal branchlets and berries of juniperus excelsa subsp. excelsa and j. excelsa subsp. polycarpos were collected, dried and extracted with ethanol/h2o (80/20 v/v) via pe...

The endocytosis of the T cell differentiation antigen CD4 has been investigated in CD4-transfected HeLa cells, the promyelocytic HL-60 cell line, and in a number of leukemia- or lymphoma-derived T cell lines. CD4 internalization was followed using radioiodinated antibodies in an acid-elution endocytosis assay, or by covalently modifying cell surface proteins with biotin and analyzing CD4 distri...

cervical cancer is the most common gynecologic cancer and the second most common cancer in women worldwide. herbal preparations are used to treat cancer for centuries. the aim of this study was investigate the cytotoxic effects of the methanol extract of citrullus colocynthis and volatile oils of iranian c. medica on hela cell line. after preparation extract and volatile oils, different concent...

Background:  Cotton seed is one of the main sources of protein in animal feeds, containing gossypol, which has been shown to have toxic effects. Results reported by various studies also indicate the anti-cancer effects of gossypol on various cell types. However, its toxic effects on human and animal cells have not been fully established. This study was planned to investigate, for the first time...

Phenolic compounds including flavonoids and phenolic acids are plants secondary metabolites. Due to their ability to act as antioxidant agents, there is a growing interest to use those components in traditional medicine for cancer prevention or treatment. The aim of this study was to measure the amounts of total phenolics and flavonoids as well as anti-proliferative effect of aqueous extract of...
