    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.

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. buy lexapro online safely 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.

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.

    even if benzodiazepine use might also be an early marker of a condition associated with an increased risk of dementia. Unwarranted long term use of these drugs should be considered as a public health concern.” [Emphasis added] On October 17, I wrote a post on this topic. In that post I noted that I had not been able to find an APA comment on the by Vabren Watts, Ph D. The problem for the APA is that the evidence implicating benzos as a causative factor in the development of Alzheimer’s disease is mounting. “‘Somewhere along the way, the message got lost, and patients were allowed to use benzodiazepines for months and years,’ said Mohit P. D., a member of APA’s Council on Geriatric Psychiatry. The APA can’t ignore this reality, but at the same time they can’t afford to alienate either pharma, or their own members who are prescribing these products. Here are some quotes from the article, interspersed with my comments. “‘Prevalence of [benzodiazepines] use among elderly patients is consistently high in developed countries … Chopra, who was not involved with the study, told Psychiatric News that guidelines recommend that the anxiolytic and insomnia medicines are to be used on a daily basis for no longer than four to six weeks.” This is a slick rewriting of history. “Researchers caution physicians to take more care when prescribing benzodiazepines.” Strictly speaking, this is accurate. de Gage et al did indeed write: “…treatments [with benzodiazepines] should be of short duration and not exceed three months.” But they also wrote: “Our study reinforces the suspicion of an increased risk of Alzheimer type dementia among benzodiazepine users, particularly long term users, and provides arguments for . [ranging] from 7 percent to 43 percent,’ noted the researchers.” This is the first quote that Dr. In fact, the message that these products would correct non-existent anomalies in their brains. Our findings are of major importance for public health, especially considering the prevalence and chronicity of benzodiazepine use in older people and the high and increasing incidence of dementia in developed countries. Watts provides from the de Gage et al study, and although it provides an important demographic reality, it is not the main issue. The promotion of benzos by the psychiatry-pharma alliance is one of the great commercial success stories of this business. In such conditions, a risk increased by 43-51% in users would generate a huge number of excess cases, even in countries where the prevalence of use of these drugs is not high.” [Emphasis added] “Carefully evaluating the indications for use” of a drug class, is light-years beyond taking “more care when prescribing.” The former denotes a complete re-appraisal of the status quo. This is a nice example of the spin tactic known as deflection, and watch how skillfully Dr. His next sentence reads: “International guidelines recommend short-term use of the drug, mainly because of withdrawal symptoms that make discontinuation problematic; however, the study noted, use of benzodiazepines is often long term in older people.” The issue here is that benzodiazepines, for decades one of the mainstays of psychiatric prescribing, are almost certainly of those drugs and the potential for addiction when used long-term.
