First study to ever quantify effects of estrogen as a stimulant of pheromones

A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the males into just about the sexiest snake in the neighborhood - attracting dozens of other males eager to mate.

Cyclin D1 oncogene may promote chromosomal instability

A team of researchers at Jefferson's Kimmel Cancer Center (KCC) led by Richard G. Pestell, M.D., PhD., FACP, Director of the KCC and Chair of the Department of Cancer Biology, have shown in a study published online Feb. 6 in the Journal of Clinical Investigation that the oncogene cyclin D1 may promote a genetic breakdown known as chromosomal instability (CIN). CIN is a known, yet poorly understood culprit in tumor progression.

Novel stem-cell technique to enhance bone growth

A research team led by UC Davis Health System scientists has developed a novel technique to enhance bone growth by using a molecule which, when injected into the bloodstream, directs the body's stem cells to travel to the surface of bones.

Researchers reveal how molecular imaging can solve breast cancer mysteries

In two new studies featured in the February issue of the Journal of Nuclear Medicine, researchers are revealing how molecular imaging can be used to solve mysteries about difficult cases of breast cancer.

New ACCP guidelines address DVT/PE risk factors for long-distance travel

New evidence-based guidelines from the American College of Chest Physicians (ACCP) address the many risk factors for developing a deep vein thrombosis (DVT), or blood clot, as the result of long-distance travel.

Soy isoflavone supplements do not reduce breast cancer cell proliferation

Soy isoflavone supplements did not decrease breast cancer cell proliferation in a randomized clinical trial, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Scientists uncover genes that govern male and female behaviors

Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviors that separate men from women. But how? Now a team of scientists at the University of California, San Francisco (UCSF) has uncovered many genes influenced by the male and female sex hormones testosterone and estrogen that, in turn, govern several specific types of male and female behaviors in mice.

Caffeine intake may change a woman’s estrogen levels: Study

The study, published in the American Journal of Clinical Nutrition, looked at more than 250 women ages 18 to 44, and found that for white women, caffeine appeared to lower estrogen levels, while in Asian women it seemed to raise them.

New research gains increased respect for contraceptive method

Imagine a contraceptive that could, with one or two painless 15-minute non-surgical treatments, provide months of protection from pregnancy. And imagine that the equipment needed were already in physical therapists' offices around the world.

Caffeine intake among women of child-bearing age influences estrogen levels

Asian women who consumed an average of 200 milligrams or more of caffeine a day-the equivalent of roughly two cups of coffee-had elevated estrogen levels when compared to women who consumed less, according to a study of reproductive age women by researchers at the National Institutes of Health and other institutions.

Researchers uncover 13 novel genetic loci linked with onset of menopause

An international team of researchers from the Boston University Schools of Public Health and Medicine and other institutions has uncovered 13 genetic loci, linked to immune function and DNA repair, that are factors in the age of onset of menopause.

Red wine could play a role in lowering risk of breast cancer

Aromatase inhibitors (AIs) prevent the conversion of androgens to estrogens, and could play a role in the development of breast cancer. This study of 36 pre-menopausal women consisted of a cross-over intervention trial to determine if there were differences between red wine and white wine in their effects on AIs.

Study explains gender-related incidence of liver cancer

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.

Oral contraceptive pills help relieve period pain: Study

A three decade long study has proven that oral contraceptive pills may alleviate painful periods for some women. Estimates suggest more than half of women have suffered from the condition, called dysmenorrhea, at some point.

Testing for osteoporosis – how often?

A new study shows that many women who get screened for osteoporosis may not need it. It suggests that the current guidelines result in too many unnecessary tests, increasing costs and sometimes spurring unnecessary treatment.

HRT and breast cancer – the link questioned as study flaws are reported

There is a renewed doubt over the link between hormone replacement therapy and breast cancer after researchers cast aspersions over its justification.

Two new studies focus on causes of arrhythmia and SCD

Researchers in Rhode Island Hospital's Cardiovascular Research Center have published two new studies focusing on the causes of arrhythmia and sudden cardiac death (SCD) when a genetic disorder is present.

Research reports on effectiveness of Scriptaid in breast cancer cell lines

Although endocrine therapy for breast cancer has shown excellent results in controlling the disease, responsiveness to the therapy depends on whether or not there is expression of estrogen receptors in breast cancer cells. Research from the Sbarro Institute for Cancer Research and Molecular Medicine, a nonprofit cancer, cardiovascular and diabetes research center located in Philadelphia, PA, reports on the effectiveness of a new molecule, Scriptaid, that restores receptivity to endocrine therapy in breast cancer cell lines that had tested negative for the expression of estrogen receptors.
