Reducing levels of protein FKBP51 may yield new antidepressant therapies

Decreasing expression of a protein associated with susceptibility to depression made old mice resistant to depressive-like behavior while improving their hormonal response to stress, a study led by researchers at the University of South Florida found. The lack of this protein, FKBP51, did not adversely affect their memory, learning, or basic motor functions.

Lignans lower risk of death in women with breast cancer

Phytoestrogens are plant compounds which, in the human body, can attach to the receptors for the female sexual hormone estrogen and which are taken in with our daily diet. A number of findings have attributed a cancer protective effect to these plant hormones. At DKFZ, a team headed by Prof. Dr. Jenny Chang-Claude summarized the results of several studies in a meta-analysis last year and showed that a diet rich in phytoestrogens lowers the risk of developing breast cancer after menopause.

Chemotherapy linked to speech difficulties among cancer patients

Patients who have received high doses of chemotherapy may find it harder to express themselves verbally, according to new research from the Sahlgrenska Academy at the University of Gothenburg, Sweden. Speech difficulties among cancer patients who received chemotherapy treatment were two times higher than among those who did not.

Pancreatic mesenchyme plays central role in the formation of mature beta cells

A somewhat mysterious soft tissue found in the fetus during early development in the womb plays a pivotal role in the formation of mature beta cells the sole source of the body's insulin. This discovery, made by scientists at University of California, San Francisco (UCSF) and Texas A&M University, may lead to new ways of addressing Type 1 and Type 2 diabetes.

New guidelines for the treatment of acromegaly, a serious growth hormone disorder

It’s said a lot can happen in seven days. In seven years, a lot has happened in the understanding of acromegaly, a debilitating condition that causes a patient to have too much growth hormone. It’s seven years since the American Association of Clinical Endocrinologists last produced guidelines for the diagnosis and treatment of acromegaly. Their 2004 guidelines were just 13 pages long. Their latest, the 2011 guidelines, have grown – to 44 pages.

Tiny molecule could bind to B cell EB12 receptor and prevent cancer

Infection with Epstein Barr means that the B cells, which are the primary memory cells of the immune system, are hi-jacked. When the virus has penetrated, researchers observe an excess of a special bio-antenna, a receptor known as EB12, suddenly sprouting from the surface of the B cells. But why they do so remains a mystery.

Dissimilar interaction of opioid receptors may explain why men, women experience pain differently

Women and men experience pain, particularly chronic pain, very differently. The ability of some opioids to relieve pain also differs between women and men. While it has been recognized since the mid-nineties that some narcotic analgesics are more effective in women than men, the reason for this difference was largely unknown.
