Ref ; Effects of transdermal and oral contraceptives on estrogen-sensitive hepatic proteins Contraception , Volume 74 , Issue 4 , Pages 293 - 296. Elsevier Article Locator
Also this site ( "High CBG Addison's Disease"Copyright ©2006 Mike Welch ) indicates a link between high Cortisol Binding Globulin and addisons disease!
So basically what im wondering is if the cause for my weak adrenals is my high estradiol?
Once cortisol gets bound to CBG is it rendered completly inactive or is it just in reserve for use when it is needed?
What about SHBG and TBG, do these render testosterone and thyroid inactive?
Thanks... |
Nice post. Thats the way to do it.
Actually it is a moot point. The system is dynamic and held in equilibrium by many factors. There are many possible stable states. It is further complicated in that their are more than one binding protein of any given hormone.
The effect of E2 on shbg, etc is well known.
I would think that if one really wants to undrstand the cross action activity of binding globulins you will have to study the stereo structure of the mulecules involved.
This is definitely valuble research you are starting. Hope you continue and keep us informed.
