Other dietary components appear to have similar action, including iosthiocyanates, which are found in sulfur and cruciferous vegetables, such as cabbage, kale, broccoli, and watercress; organoselenium compounds found in garlic; biotin-rich foods such as chard and egg yolk, and alpha lipoic-acid-rich foods, such as green leafy vegetables.
Among the topics are the stem cell paradigm and its application to prostate cancer, interactions between the androgen receptor and other signaling pathways implicated in prostate cancer growth and development, organoselenium compounds as a prospect for therapy, molecular genetic alterations in the prostate cancer microenvironment, implication of lysophosphatidic acid signaling and receptor-mediated mechanisms contributing to the development of prostate carcinoma, redox state and prostate cancer behavior, and how piezoelectric interaction with prostatic crystalloids may explain the relationship between environmental electromagnetic fields and prostate cancer.
In general, organoselenium compounds are more reactive than their sulfur counterparts: the C-Se bond (234 KJ/mol) is weaker than the C-S bond (272 KJ/mol).
They then used their method in a study of several organoselenium compounds, including selenonium compounds, and reported various degrees of metabolism to TMSe by the different compounds.
