Elevated steroid sulfatase expression in breast cancers

Cells of the zona fasciculata and zona reticularis lack aldosterone synthase (CYP11B2) that converts corticosterone to aldosterone, and thus these tissues produce only the weak mineralocorticoid corticosterone. However, both these zones do contain the CYP17A1 missing in zona glomerulosa and thus produce the major glucocorticoid, cortisol. Zona fasciculata and zona reticularis cells also contain CYP17A1, whose 17,20-lyase activity is responsible for producing the androgens, dehydroepiandosterone (DHEA) and androstenedione. Thus, fasciculata and reticularis cells can make corticosteroids and the adrenal androgens, but not aldosterone.

Steroid diabetes must be distinguished from stress hyperglycemia , hyperglycemia due to excessive intravenous glucose, or new-onset diabetes of another type. Because it is not unusual for steroid treatment to precipitate type 1 or type 2 diabetes in a person who is already in the process of developing it, it is not always possible to determine whether apparent steroid diabetes will be permanent or will go away when the steroids are finished. More commonly undiagnosed cases of type 2 diabetes are brought to clinical attention with corticosteroid treatment because subclinical hyperglycemia worsens and becomes symptomatic. Generally, steroid diabetes without preexisting type 2 diabetes will resolve upon termination of corticosteroid administration.

High dosages of oral corticosteroids taken daily for prolonged periods of time can have serious systemic side effects including bone loss ( osteoporosis), increased risk of infections and diabetes and cataracts, thinning of skin, stretch marks, increased facial/body hair growth, acne, fluid retention, weight gain with redistribution of fat (fat deposits on back and face, thinning of limbs), muscle weakness, decreased resistance to infections, stomach ulcers, mood swings, insomnia, suppression of the body's own production of cortisol, etc.

Great post. Its sad everyone thinks testosterone is a joke (people that are accusers of steroid use) however they don’t realize how important hormones are. im a 23 year old male, have always been ripped, but the last year or so have shown really bad symptoms of what I thought was low T. Turns out my estradiol is 56, normal is 17 to around 35. My life went from perfect to pure HELL and my doctor is more concerned on “why my hormones are out of sync” while I continue to suffer horrible side effects. My libido is gone, amonst other things but my latest concern is EXTREME muscls wasting due to prolonged high aromitization. I don’t just mean loss in size, my forearms literally feel like they have rotted away inside my skin. Its very scary. I’m trying to figure out how I can get my doctors head out of his ass to give me an AI to combat all this estrogen but am having a difficult time. Men need to immediately seek medical help upon any first signs of this, I waited and am now paying very dearly for it. Please brethren DO NOT TAKE EXCESS ESTROGEN as a light issue, you WILL SUFFER!!!!
