Study explains link between infertility and hyperprolactinaemia

One of the most frequent is the existence of tumours that induce an over-secretion of this hormone. These women present with chronic infertility due to anovulation. Thanks to the work of the Inserm researchers from unit 693 "Steroid receptors: endocrinian and metabolic physiopathology", the intimate mechanism of the hyperprolactinaemia alterations affecting reproduction in mice has been discovered.

BioResearch Open Access explores Cell-SELEX technology

SELEX is a rapid, efficient, and iterative high-throughput method for screening large libraries of molecules to identify those with the potential to be developed as drug compounds or research tools. Advances in SELEX technology that have enabled screening in live cells, called Cell-SELEX, are explored in a comprehensive Review article published in BioResearch Open Access, a bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc.

New book focuses on Wnt signaling

Wnt proteins are signaling molecules that play critical roles during embryonic development and in the regeneration of adult tissues. They bind to Frizzled and LRP family receptors on the cell surface, triggering a series of events that cause beta-catenin to enter the nucleus and activate transcription factors that control cell fate and cell proliferation. Mutations in components of the Wnt pathway lead to developmental defects and are common in cancer.

Study sheds light on how overeating can lead to obesity and diabetes

New research from Mount Sinai School of Medicine sheds light on how overeating can cause a malfunction in brain insulin signaling, and lead to obesity and diabetes. Christoph Buettner, MD, PhD, Associate Professor of Medicine (Endocrinology, Diabetes and Bone Disease) and his research team found that overeating impairs the ability of brain insulin to suppress the breakdown of fat in adipose tissue.

New way to image how brain cells coordinate with each other to control specific behaviors

A team led by MIT neuroscientists has developed a way to monitor how brain cells coordinate with each other to control specific behaviors, such as initiating movement or detecting an odor.

Two opposing mechanisms support voluntary forgetting of unwanted memories

If only there were a way to forget that humiliating faux pas at last night's dinner party. It turns out there's not one, but two opposite ways in which the brain allows us to voluntarily forget unwanted memories, according to a study published by Cell Press October 17 in the journal Neuron.

New insights into wiring and firing of the social brain

New insights into the wiring and firing of the "social brain" in humans and primates reveals the brain areas important in altruistic motives and behavior, and the brain regions that respond to the pain of discrimination.

Research may lead to new ways to identify women with breast cancer risks from low-dose radiation

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have identified tissue mechanisms that may influence a woman's susceptibility or resistance to breast cancer after exposure to low-dose ionizing radiation, such as the levels used in full-body CT scans and radiotherapy.

DNA damage response contains previously unknown components: Study

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida; Duke University; Johns Hopkins University; the Brazilian National Cancer Institute; and the Rio de Janeiro Federal Institute of Education, Science and Technology have discovered that an intricate system to repair DNA damage called the "DNA damage response" (DDR) contains previously unknown components, including proteins that could be targeted as sensitizers for chemotherapy.

Universal tumor testing superior to selective strategy in identifying Lynch syndrome among CRC patients

In a comparison of strategies to identify individuals with Lynch syndrome, the most common form of hereditary colorectal cancer (CRC), caused by mutations in certain genes (DNA mismatch repair [MMR] genes), universal tumor MMR testing among certain CRC patients had a greater sensitivity for the identification of Lynch syndrome compared with multiple alternative strategies, although the diagnostic improvement was modest, according to a study in the October 17 issue of JAMA.
