    Inflammation is one of the hallmarks of cancer initiation and progression (1). The increased IL-1β in breast cancers of women strongly suggests IL-1 as a potential therapeutic target in breast cancer treatment and prevention. and may be attenuated by antiestrogen therapy and diet modifications. In breast cancer patients, intratumoral levels of IL-1β were significantly higher compared with normal adjacent breast tissue. D.), Department of Clinical and Experimental Medicine, Faculty of Health Sciences, Linköping University, Department of Oncology, County Council of Östergötland, SE-581 85 Linköping, Sweden 1Division of Oncology (A. Immunohistochemistry of the biopsies did not reveal any changes in cellular content of the IL-1s, suggesting that mainly the secreted levels were affected. These results were confirmed in culture of breast biopsies. Tamoxifen or a dietary addition of 25 g flaxseed per day resulted in significantly increased levels of IL-1Ra in the breast. Tamoxifen has been reported to have numerous physiological effects that are independent of the estrogen receptor, including sensitization of resistant tumor cells to many chemotherapeutic agents. Drug-resistant cells sequester weak base chemotherapeutics in acidic organelles away from their sites of action in the cytosol and nucleus. This work reports that tamoxifen causes redistribution of weak base chemotherapeutics from acidic organelles to the nucleus in drug-resistant cells. Agents that disrupt organelle acidification (e.g., monensin, bafilomycin A) cause a similar redistribution. Measurement of cellular p H in several cell lines reveals that tamoxifen inhibits acidification of endosomes and lysosomes without affecting cytoplasmic p H. Similar to monensin, tamoxifen decreased the rate of vesicular transport though the recycling and secretory pathways. Organellar acidification is required for many cellular functions, and its disruption could account for many of the side effects of tamoxifen.

General description Tamoxifen is a selective estrogen response modifier SERM, protein kinase C inhibitor and anti-angiogenetic factor. Nov 29, 2016. In this 2-Part article series you'll discover how tamoxifen and estrogen work in the body, why tamoxifen is still being recommended, the list of.

    For women who have estrogen receptor-positive breast cancers, hormonal therapy is usually recommended after primary treatment with surgery and possibly chemotherapy and/or radiation therapy. Choices include tamoxifen or aromatase inhibitors such as Arimidex, Femora, or Aromasin. How does the cost and effectiveness of these medications compare, and what do you need to know? What happens if you have difficulty paying for these drugs? We know that even after primary treatment for breast cancer there is a risk of recurrence. And late recurrences several years or even decades after treatment are more common with estrogen receptor-positive tumors. Hormone therapies have been shown to reduce the risk of recurrence and improve survival rates. Resistance to tamoxifen therapy in some estrogen receptor positive breast cancers may originate from in utero exposure to endocrine disrupting chemicals, research in animal studies suggests. This study provides a new path forward in human research as about half of the breast cancers treated with this common cancer therapy do not respond well, say researchers. An animal study suggests that resistance to tamoxifen therapy in some estrogen receptor positive breast cancers may originate from in utero exposure to endocrine disrupting chemicals. The study provides a new path forward in human research as about half of the breast cancers treated with this common cancer therapy do not respond well, say researchers at the Georgetown Lombardi Comprehensive Cancer Center, who led the multi-institutional research. ), identified four genes that are linked to tamoxifen resistance and poor prognosis of breast cancer, by comparing results obtained in a new animal model, in human breast cancer cells grown in culture, and in publically available datasets collected from thousands of estrogen receptor positive breast cancer patients treated with tamoxifen. "Higher estrogen levels in utero have been known to increase risk of estrogen positive breast cancer in laboratory animals -- and humans -- but it wasn't known until this study that these elevated levels may also be responsible for tamoxifen resistance," says the study's co-lead author, Leena Hilakivi-Clarke, Ph D, a professor of oncology at Georgetown Lombardi.. Researchers further demonstrated that changes in these genes were reversed by adding well-tolerated epigenetic modifying drugs, valproic acid and hydralazine, to tamoxifen therapy regimen.
