cancer is one of the main causes of mortality in the world which appears by the effect of enviromental physico-chemical mutagen and carcinogen agents. the identification of new cytotoxic drugs with low side effects on immune system has developed as important area in new studies of immunopharmacology. thymoquinone (tq), derived from the medicinal spice nigella sativa (also called black cumin) ex...

cancer is one of the main cause of mortality in the world which appears by the effect of enviromental physico-chemical mutagen and carcinogen agents. the identification of new cytotoxic drug with low sid effects on immune system has developed as important area in new studies of immunopharmacology. curcumin is a natural polyphenol with anti-oxidative, anti-inflammatory and anti-cancer properties...

background: norepinephrine plays a trophic role in the control of cell replication and differentiation in target cells that express adrenergic receptors. methods: in this study, we have tested the influence of infraphysiological, physiological and supraphysiological concentrations (0.0001 nm, 1 nm, 10000 nm) of human norepinephrine on the proliferation of breast cancer cells (human breast adeno...

     The chloroform soluble fractions of ethanolic extracts of five Inula belonging to the Compositae family were evaluated for cytotoxic activity against five different cell lines including CACO2 (human colon adenocarcinoma), MCF7 (human breast adenocarcinoma), HEPG2 (human hepatocellular carcinoma), VERO (green African monkey kidney) and WEHI164 (balb c mouse fibrosarcoma). Cytotoxic...

introduction: daphne species has both pharmaceutical applications and anti tumor activity. it has been shown that the extract of daphne mucronata is effective in decreasing the size of breast adenocarcinoma in rats. we investigated the mechanism of action and the effects of the extract on tnf-a and tnf-a receptors on cultured human monocytes. material and methods: the breast tumors were induced...

although most breast cancers are adenocarcinomas of the mammary gland, primary breast sarcomas may also arise from mammary gland mesenchymal tissue. sarcomas represent less than 1% of primary breast neoplasms. these tumors are at high risk of recurrence and are known to have poor prognosis. surgical resection is the primary treatment for these lesions and axillary lymph node dissection is not r...

background : breast cancer is a complicated disease and has various clinical manifestations and prognosis. the aim of this study is to make a breast cancer model suitable for basic, preclinical and clinical studies. materials and methods: five virgin bulb/c mice aged 6 weeks and spontaneous murine mammary adenocarcinoma cells (mmac) were used. after anesthesia induction, 1-3 million of mmacs we...

despite a lot of research, the etiology and progression of breast cancer remain incompletely understood. recently, human cytomegalovirus (hcmv) was reported as a risk factor for breast cancer. the aim of this study was to know whether breast cancer could be caused by cytomegalovirus or not? in this experiment seventeen samples of razi/a mice with spontaneous breast cancer were being gathered fr...
