Patients with castration-resistant prostate cancer treated with the androgen inhibitor abiraterone and who had high baseline hormone levels had longer overall survival compared with patients with low hormone levels, according to data presented at the AACR Annual Meeting 2012, held here March 31 - April 4. If confirmed, these data mean that levels of hormones, specifically adrenal androgens, may provide physicians with another way to predict the efficacy of therapy in patients with...

Study presented Friday at 65th annual meeting of Society of Surgical Oncology Could blocking a testosterone receptor lead to a new way to treat an aggressive form of breast cancer? That's a question researchers at Mayo Clinic in Arizona and the Translational Genomics Research Institute (TGen) are exploring. Preliminary results of a Mayo Clinic - TGen collaborative study shows the testosterone receptor may be a potential target to attack in treating triple negative breast cancer (TNBC)....

Men are four times more likely to develop liver cancer compared to women, a difference attributed to the sex hormones androgen and estrogen. Although this gender difference has been known for a long time, the molecular mechanisms by which estrogens prevent -- and androgens promote -- liver cancer remain unclear. Now, new research, published in Cell this week from the lab of Klaus Kaestner, PhD, professor of Genetics in the Perelman School of Medicine at the University of Pennsylvania, has...

Herbicide Spurs Reproductive Problems In Many Animals

An international team of researchers has reviewed the evidence linking exposure to atrazine — an herbicide widely used in the U.S. and more than 60 other nations — to reproductive problems in animals. The team found consistent patterns of reproductive dysfunction in amphibians, fish, reptiles and mammals exposed to the chemical. Atrazine is the second-most widely used herbicide in the U.S. More than 75 million pounds of it are applied to corn and other crops, and it is the most...

Teacher, pilot, nurse or engineer? Sex hormones strongly influence people's interests, which affect the kinds of occupations they choose, according to psychologists. "Our results provide strong support for hormonal influences on interest in occupations characterized by working with things versus people," said Adriene M. Beltz, graduate student in psychology, working with Sheri A. Berenbaum, professor of psychology and pediatrics, Penn State. Berenbaum and her team looked at people's...

Elevated sex hormone levels associated with chronic disease risk A recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM) found that postmenopausal women who smoke have higher androgen and estrogen levels than non-smoking women, with sex hormone levels being highest in heavy smokers. Previous studies have shown that high levels of estrogens and androgens are potential risk factors for breast and endometrial cancer as...

(Ivanhoe Newswire) "“ The male hormone androgen may spark the growth of some breast cancer tumors in women, according to this study. "We identified a novel subtype of breast tumor which grows in response to androgen but not estrogen, and have uncovered the signaling pathways involved in its growth," senior author Myles Brown, MD, was quoted as saying. "And we've demonstrated that drugs capable of blocking these pathways, including the receptor for androgen itself, can inhibit tumor...

Although it sounds like a case of gender confusion on a molecular scale, the male hormone androgen spurs the growth of some breast tumors in women. In a new study, scientists at Dana-Farber Cancer Institute provide the first details of the cancer cell machinery that carries out the hormone's relentless growth orders. The study, published the journal Cancer Cell on July 12, provides scientists with several inviting targets "“ cell proteins that snap into action in response to androgen...

Cancer is crafty. When one avenue driving its growth is blocked by drugs targeting that path, the malignancy often creates a detour, finding an alternative route to get around the roadblock. In a study at UCLA's Jonsson Comprehensive Cancer Center, researchers found that when a common type of prostate cancer was treated with conventional hormone ablation therapy blocking androgen production or androgen receptor (AR) function"“ which drives growth of the tumor "“ the cancer was...

Researchers from the Kimmel Cancer Center at Jefferson and two other institutions have discovered new evidence that suggests the "longevity" protein SIRT1, known for its life-spanning effects in different species, can inhibit the development of a known precursor to prostate cancer, prostatic intraepithelial neoplasia (PIN). Results from the study could lead to new cancer prevention drugs that could not only block prostate cancer but promote longevity. The study, published in the February 1...
