DHEA is a natural circulating hormone and the body’s production of it decreases with age. Men take DHEA as an over-the-counter supplement because it has been suggested that DHEA can reverse aging or have anabolic effects since it can be metabolized in the body to androgens.
Dehydroepiandrosterone (DHEA) is being evaluated in the basic science laboratories as a potential treatment for adenocarcinomas, with some initial promise for success. However DHEA can be metabolically converted to androgenic compounds, possessing unwanted side effects. A patient with advanced prostate cancer with progressive symptomatology was treated with DHEA after other treatment regimens failed. Many of his symptoms improved on DHEA therapy, but his cancer also flared dramatically during treatment. His previous hormonally unresponsive cancer subsequently responded transiently to third-line hormonal therapy with diethylstilbestrol (DES). Adrenal precursor molecules such as DHEA may have significant therapeutic benefits in a number of diseases of the elderly, however their utility may be limited by potential androgenic side effects including endocrine epithelial cell growth. The development of analogue compounds with less conversion to androgenic metabolites should be considered, as molecules such as DHEA are more widely tested and utilized clinically. Read more on this clinical study.
Human epidemiological and pilot clinical studies suggest that elevated levels of DHEA in the blood may be beneficial in preventing heart disease, improving immune function and well-being in the elderly, and combating depression. The hormone may also be helpful in treating systemic lupus erythematosus. Numerous animal studies have shown that DHEA may prevent obesity, diabetes, cancer, and heart disease, as well as enhance the immune system and expand life span.
With passage in 1994 of the Dietary Supplement Health and Education Act, DHEA can now be sold as an over-the-counter nutritional supplement, so long as labels don’t make any unsubstantiated health claims. But that isn’t stopping a proliferation of advertisements from touting the benefits of DHEA as a dietary supplement.
“There’s much confusion in the field right now because of conflicting information and hype,” observes Arthur Schwartz, a professor of microbiology at the Fels Institute for Cancer Research and Molecular Biology in the Temple University School of Medicine. Schwartz, a pioneer in the DHEA field, has been working on DHEA and cancer prevention for the last two decades.
Investigations in DHEA’s role in cancer prevention really took off in the late 1970s when Temple’s Schwartz reported that when mice prone to contracting breast cancer were given DHEA throughout their life span, the incidence of cancer in the rodents decreased significantly (A.G. Schwartz, Cancer Research, 39:1129-32, 1979). He is now working in collaboration with the National Cancer Institute and Aeson Therapeutics Inc., a Tucson, Ariz.-based biotech firm, on Phase I and upcoming Phase II trials on a fluorinated form of DHEA called fluasterone. This form doesn’t show the same testosterone-producing effects as regular DHEA, which is considered a benefit for any potential therapeutic uses.
Jeffrey Jacob, chairman of Aeson Therapeutics, says that his company and Schwartz have performed preclinical trials in mouse models of colon, skin, breast, and prostate cancer over the last year and a half. “We also have animal data for lupus, multiple sclerosis, and Type II diabetes that show that our compound is very effective. We went into the clinic in late January.”
The first two safety studies in the cancer clinical trials are just finishing up, notes Jacob. These are performed in healthy people to look for safety and tolerance in humans, toxicity in blood levels, and androgen markers, because fluasterone isn’t converted into testosterone and other sex hormones. Phase II trials in breast cancer prevention with the National Cancer Institute are planned for this summer, he reports.
Fluasterone, which isn’t a public-domain compound like natural forms of the hormone, is more attractive to private firms. “It’s a proprietary form of DHEA,” Jacobs explains. “We have numerous patent applications on fluasterone throughout the world. We expect the patents in the United States to be issued sometime this year.”
Stephen Hursting, an assistant professor of epidemiology and carcinogenesis at the M.D. Anderson Cancer Center in Houston who also works on DHEA’s role in cancer prevention, finds the fluasterone research some of the most promising so far in the field of DHEA and cancer. Within the past year, Hursting and colleagues have published three studies on DHEA and mouse lymphomas. In 1995, Hursting conducted a panel study (S. Hursting et al., Cancer Research, 55:3949-53, 1995) and found that DHEA “was by far and away the most effective. It particularly shut down the lymphoma development in p53 knockout mice.”
In another study that is due to be published soon, Hursting and Ellen Richie, an immunologist also at M.D. Anderson, are delving into the mechanism of DHEA in retarding tumor growth (T. Wang et al., Cancer Letter, in press). This paper will show the apoptotic effect of DHEA on tumors.
“My [jury] is still out as far as DHEA as a chemopreventative is concerned because of its apoptotic and androgenic capabilities,” says Hursting. “Research is still a long way away from convincing me of its benefit as a daily supplement.”
Ramifications of dehydroepiandrosterone (DHEA) supplementation on hormonal, metabolic and behavioral position in patients with hypoadrenalism. Research at the Washington College of Medicine can see that there is a substantial link between low melatonin amounts and weight gain, specifically around the abdominal area. What, then, might be the consequences of DHEA on cancer avoidance or promotion? Furthermore, co-incubation of DHEA with progesterone demonstrated an additive impact in decreasing the cell development in mouse cell line, however, not in human cell collection A lot more clinical studies will be asked to clarify the result of DHEA on insulin sensitivity. Vegetables, like bell peppers and fruit, abundant with vitamin C, decrease the aromatase enzyme in charge of converting an excessive amount of estrogen from testosterone.
DHEA Uses, Benefits, And UNWANTED EFFECTS
Dehydroepiandrosterone or DHEA is an all natural hormone released by the adrenal gland. Since small was known about the experience of DHEA as an anti-cancer tumor molecule in HCC, our group investigated the chance that it might kill hepatoma cells. We found that DHEA kills liver cancer tumor by a death process referred to as programmed cell loss of life type II (PCD II) or autophagic cell death, quite not the same as classical apoptosis. Entering detail, DHEA primes the substantial activation of the proteins p62, which is in charge of PCD II and the killing around 50% tumor cells in mere 24 hours. This effect appears to be very particular for HCC, since DHEA has the capacity to destroy cervix carcinoma cells as well, rather by triggering canonical apoptosis.
Recent research suggest a pivotal function of the IAPs in preserving the immortality of tumor cells ( Yang et al. 2003 ). Because the expressions of many of the IAP genes are regarded as stimulated by an NF-ÎºB-dependent system, we examined the expression of IAPs in AtT20 cells by RT-PCR. The outcomes showed a variety of IAPs such as for example survivin, mNAIP, Bruce, XIAP, IAP1, and IAP2 had been expressed in AtT20 cells (Fig. 4A ). We then centered on the expression of survivin, a representative IAP expressed in the AtT20 cell series. When cells had been treated with DHEA or PRT, the transcription activity of survivin was considerably attenuated in a dose-dependent way (Fig. 4B ). Because the promoter activity of survivin provides been shown to end up being regulated by NF-ÎºB ( Kawakami et al. 2005 ), our results improve the likelihood that DHEA and PRT inhibit the expression of IAPs like survivin and induce apoptosis through inhibition on the NF-ÎºB pathway.
Dehydroepiandrosterone (DHEA) is a fragile androgen and had been proven to have anti-tumor, anti-adipogenic and anti-inflammatory results on mouse and additional rodent models, however, not on human beings, suggesting a systemic level difference between mouse and human being. Our previous research on DHEA biological features involving a number of cell lines, recommended that the practical differences between mouse and human being existed actually at the cellular level. Therefore, using mouse and human being melanoma cell models, in-vitro ramifications of DHEA on cell growth, system of cell death and system of DHEA actions were studied. Outcomes indicated a differential biological ramifications of DHEA between mouse and human being melanoma cell lines. These in-vitro research also recommended that the differential biological results observed between both of these cell lines could be because of the difference in the manner DHEA was prepared or metabolized in the cell.
There is evidence that this, in turn, provides some protection against prostate cancers. slimy paste or glue (poisonous poisons). No wonder they perish of the forced inactivity of their shoebox homes.
Progesterone is unveiled by the rupturing of the ovum follicle during ovulation. While prolonged cardio can be bad, brief bursts of heavy lifting (kettlebells, deadlifts, legups, lunges) can be beneficial since they trigger a cascade of advantageous hormone reactions. For example, they can substance a single cream that contains several hormones at the specific doses needed for that patient.

After natural menopausal or surgical removal of the sex gland, for as long as a woman existence, the pituitary gland continues to discharge very high amounts of follicle stimulating hormone (FSH) in an attempt to stimulate ova in the ovaries to produce the extra estrogen. Estradiol patches and progesterone capsules are examples of bio-identical hormones that can be prescribed by doctors by your physician if he or she is unpleasant with prescribing a custom worsened bio-identical hormone product.
DHEA (Dehydroepiandrosterone) Steroid Hormone Study On Cancer
Too much estrogen is a problem for men and women and too many folks have too much of it. Extra estrogen can accelerate ageing, worsen prostate health, increase surplus fat and muscle atrophy, increase hair thinning and trigger sexual dysfunction.
As I clarify in my own book, The Metabolic Plan, that is probably the most important keys to living an extended and healthy existence. As we age, a lot of people lose muscle and gain body fat. You need to understand the profound effect it has on standard of living. Beyond the aesthetic impact, which impacts our self-esteem and lifestyle, the accumulation of extra fat and lack of muscle causes a progressive lack of functional capability and a dramatic alteration in glucose rate of metabolism. A lot more than 70% of obese individuals can be diabetic, and the diabetic condition is similar to turbo-aging, producing rapid degeneration through the entire body and brain.
After years of intensive study and experimentation, in the entire year 2002, the Prostate Cancer Study Institute came up with a remedy to combat the development of tumor cells in the prostate gland. They found that when Ketoconazole and Hydrocortisone had been combined, the outcomes on a cancer individual were nothing brief of a miracle. Papers had been published post clinical trials. Those that conducted the study added High Dosage Ketoconazole to Hydrocortisone when dealing with 17 patients, who wanted to end up being their guinea pigs.
Invasion and metastasis of cancer cells will be the leading factors behind mortality in patients with malignancy; therefore, since a protective part of DHEA against malignancy has been described, the result of DHEA on the migration of cervical malignancy cells was evaluated here.
Catabolism is the process where the body burns fat. Many popular diet programs, including most low-carb programs, focus just on catabolism, while totally ignoring the other, beneficial component – anabolism. Therefore, they don’t assist you to stay young longer, build up muscle or help your system produce more anabolic hormones. It is necessary to understand that while catabolism destroys fats, in addition, it destroys bone and proteins.
Proteins have become important for your wellbeing. As we age group, we begin shedding proteins from muscle tissue, cartilage, and epidermis. This leads to a reduction in bone and muscle mass, issues with our joints, and even lines and wrinkles. If you would like to stay young longer you should take steps to avoid protein and bone loss. As a result, in order to lose weight in healthy way, you need to kick-start your metabolism also to increase your body’s natural creation of anti-aging anabolic hormones.
A University of Southern California research discovered that 8 out of 27 males acquiring Finasteride for enlarged prostate, created tumors within one year, regardless of the drug lowering DHT by 67%. It really is my look at that unidentified elevated degrees of estrogen in the prostate may be the problem, not really DHT. While Finasteride lowers DHT, it could cause impotency.
On the other hand, beta sitosterol in found palmetto could be more effective to revive urine circulation, without impotency. Beta Sitosterol enhances rate of metabolism of DHT and androgen receptor binding, while Finasteride will not. Even though Finasteride can decrease DHT in the prostate up to 80%, it just reduces the prostate size by about 20%. Some 60-65% of males obtain no improvement with Finasteride! Over 5% of Finasteride users suffer reduced libido, impotence, and ejaculatory disorders.
Stephen Cherniske: But you’re speaking as if side effects are normal, when actually they are uncommon. At the clinically effective dosage of 5 to 25 mg, the incidence of androgen-related unwanted effects is significantly less than 2%.123 When compared to known benefits, and the convenience where a safe dose could be determined, it really is unreasonable and unscientific to harp on unwanted effects that are uncommon and innocuous. Tremendous health advantages are obtainable from 5 to 25 mg of DHEA. It considerably decreases risk for diabetes and coronary disease at 25 mg each day. Both of these degenerative diseases account for a lot more than 70% of deaths in America and all that can be done is wring the hands about an adverse effect that may occur at 4 or 5 times that dose.
