    Glyphosate, component of Roundup is well known to be an endocrine disruptor.  This rat study describes the mechanism  of disruption of the Sertoli cells resulting in male infertility.  In addition to the disruption of spermatogenesis, Glyphosate was shown to deplete glutathione levels compromising detoxification.  If that is not enough, oxidative damage marker TBARS was elevated.

    glyphosate increases ER-alpha expression and activation though this study found no evidence that glyphosate bound to ER-alpha. This makes glyphosate a endocrine disrupter.

    Probably one of the more disturbing aspects of glyphosate exposure. In utero exposure, lowers Testosterone levels and effects the masculinization process of the young boy.  Very disturbing.  Our boys are being altered before they are even born.

  • one can conclude that ERβ has an overall antiproliferative effect, thereby inhibiting cancer cell proliferation and antagonizing ERα function in the breast
  • HRT with estrogen alone did not increase the risk of breast cancer in the Women's Health Initiative clinical trials program
  • colorectal normal or cancer epithelium does not coexpress ERα and ERβ
  • ...7 more annotations...
  • ERβ expression resulted in the inhibition of proliferation and G1 phase cell-cycle arrest
  • ERβ expression strongly inhibited cMyc and tumor growth in a xenograft mouse model
  • induced ERβ in CRC cells has an antiproliferative, tumor-suppressive function that is independent of ERα
  • ERs also have the ability to bind many other compounds with an estrogen-like structure, including phytoestrogens and xenoestrogens (or endocrine disruptors)
  • Phytoestrogens are a diverse class of natural compounds with structural similarity to estradiol
  • Barone et al. recently found that two ERβ-selective phytoestrogens effectively counteracted CRC tumorigenesis and surprisingly increased ERβ expression in mice with mutations of the tumor-suppressor gene adenomatous polyposis coli
  • We can conclude that estrogens are important in protecting against CRC initiation and progression, and that the protective effect most likely is mediated by ERβ

    ER beta is a new potential mode of therapy in colon cancer.  ER beta stimulation has been shown to inhibit colon cancer cell growth.
