Macrophages demonstrate plasticity, and tumor-associated macrophages (TAM) can function as immunosuppressive cells in the tumor microenvironment. Therefore, in this study, we aimed to reprogram TAM in vitro with cytokine signal alteration. Granulocyte macrophage colony stimulating factor (GM-CSF) treatment alone did not lead to changes in the expression of M1 (including IL-1β, TNFα and CXCL-10)...

PURPOSE The aim of the study was to investigate if a short-term administration of high-dose Tamoxifen (Tam) could affect the expression of biologically relevant biochemical parameters in cervical cancer tissue. EXPERIMENTAL DESIGN The study was conducted in 24 patients with histologically confirmed cervical tumors. Biopsies were obtained by colposcopy on day 0 in all patients, who then receiv...

Experiments were designed to investigate whether the tumor-associ ated macrophage (TAM) content of murine solid tumors correlates with the clonogenic ability of tumor cells to establish s.c. tumors, tumor growth rate, extent of tumor necrosis, tumor metastatic propensity, and tumor radioresponse. Of 13 tumors studied, 6 were sarcomas and 7 were carcinomas; all tumors were of spontaneous origin ...

Article history: Received on: 15/04/2016 Revised on: 21/05/2016 Accepted on: 09/06/2016 Available online: 28/06/2016 Tamoxifen (TAM) is a hormonal selective estrogen modulator used in the prevention and treatment of breast cancer. It associated with increased in the oxidative stress in cells leading to tissue injury. Sodium butyrate (NaBu) increased the glutathione redox system and diminished t...

The effect of tamoxifen (TAM) on human endometrii carci noma was investigated in nude mice bearing an estrogen recep tor-positive or estrogen receptor-negative tumor. The receptornegative tumor grew rapidly, and the rates of tumor growth of 17/3-estradiol or TAM-treated animals were identical to the rate of controls. The estradici receptor and progesterone receptor (PR) concentrations in the tu...

objective: thymoquinone (tq), as the main component of nigella sativa plant, shows anticancer properties. this study was aimed to evaluate the combined effect of tq and tamoxifen (tam) on viability and apoptosis of human breast cancer cell lines. materials and methods: in this experimental study, estrogen positive mcf-7 and estrogen negative mda-mb-231 human breast cancer cell lines were induce...

Macrophages were isolated by adherence from tumors produced by a number of murine mammary carcinoma lines and were examined by fluorescence-activated cell sorting for quantitation of leucine aminopeptidase and acid phosphatase. The tumors included three lines, 66, 67, and 168, which were originally derived from a single, spontaneously arising tumor in a BALB/cfC3H mouse and two other lines, D2A...

The objective of this study was to evaluate the antitumor effect of glibenclamide (Gli) alone or in combination with tamoxifen (Tam) on experimental mammary tumors induced by N-nitroso-N-methylurea (NMU) in nondiabetic and diabetic rats. For experimental diabetes induction, Sprague-Dawley rats were injected with streptozotocin (STZ) on the second day of life. For experimental mammary tumor indu...

Our previous short-term study has shown that 10% flaxseed (FS) inhibits the growth of human estrogen dependent estrogen receptor positive breast tumors (MCF-7) xenografts in ovariectomized (OVX) athymic mice and enhances the tumor inhibitory effect of tamoxifen (TAM). This study determined the long-term effect of 5% and 10% FS, with or without TAM, on the growth of MCF-7 xenografts in athymic m...
