I was reading in the university health news daily website that a study performed by researchers at the University of Texas . Anderson Cancer Center found that men with prostate cancer who ate 3 tablespoons of milled or ground flax seeds each day had decreased prostate cancer cell proliferation compared to similar men who did not eat flax seeds. According to the American Cancer Society, men who supplement their diets with flax seed have lower PSA levels and slower growth of benign as well as cancerous prostate cells.
Perhaps the effect of phytoestrogenic in humans it’s not fully understood as yet.
Biosynthesis of steroid hormones requires a battery of oxidative enzymes located in both mitochondria and endoplasmic reticulum. The rate-limiting step in this process is the transport of free cholesterol from the cytoplasm into mitochondria. Within mitochondria, cholesterol is converted to pregnenolone by an enzyme in the inner membrane called CYP11A1. Pregnenolone itself is not a hormone, but is the immediate precursor for the synthesis of all of the steroid hormones. The following table delineates the enzymes required to synthesize the major classes of steroid hormones.
The mechanism by which the glycyrrhizinates exert their effect on the renin-angiotensin-aldosterone system has been elucidated. 2 , 35 , 36 , 42 Competitive (and reversible) inhibition of the enzyme 11-beta-hydroxysteroid dehydrogenase results in the suppression of cortisol conversion to inactive cortisone. Consequent suppression of plasma renin activity and aldosterone levels is evident. Exchangeable sodium levels increase and cortisol occupation of mineralocorticoid receptors in the distal kidney tubules is enhanced. The condition responds to administration of spironolactone, potassium supplementation, and discontinuation of licorice.
