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.

Scientists discover new mechanisms by which RNA drugs can control gene activity

Small RNA-based nucleic acid drugs represent a promising new class of therapeutic agents for silencing abnormal or overactive disease-causing genes, and researchers have discovered new mechanisms by which RNA drugs can control gene activity.

Rituximab shows promise against primary biliary cirrhosis

An open-label study of rituximab, a monoclonal antibody for human CD20, was shown to be safe in patients with primary biliary cirrhosis (PBC) who had an incomplete response to the standard ursodeoxycholic acid (UDCA) therapy, also known as Ursodiol.

Multiple DNA repair defect in monocytes

Scientists working with Professor Bernd Kaina of the Institute of Toxicology at the Medical Center of Johannes Gutenberg University Mainz have demonstrated for the first time that certain cells circulating in human blood - so-called monocytes - are extremely sensitive to reactive oxygen species (ROS).

Version of 'Goldilocks' gene could determine future treatment for TB patients

'Goldilocks' gene could determine best treatment for TB patients Tuberculosis patients may receive treatments in the future according to what version they have of a single 'Goldilocks' gene, says an international research team from Oxford University, King's College London, Vietnam and the USA.

New England Journal of Medicine publishes Diamyd Medical's antigen-based diabetes therapy study

An article with the results of Diamyd Medical's European Phase III study of the antigen-based diabetes therapy Diamyd® has been published in the scientific journal the New England Journal of Medicine. The now published results were previously presented at the American Diabetes Association's 71st Scientific Sessions in San Diego, California, USA, on June 28, 2011.

Skin cells converted to brain cells without intermediate stem cell stage

Researchers from California have successfully converted mouse skin cells into cells which develop into the main components of the brain. The experiment, reported in Proceedings of the National Academy of Sciences, is notable because it skipped the middle “stem cell” stage in the process.

Blood cell therapy works for nasopharyngeal cancer: Study

Scientists from the Queensland Institute of Medical Research have made a breakthrough in the treatment of throat cancer. The researchers have developed a therapy that uses a patient's blood to grow special white blood cells that recognize and fight infected cancer cells. The results of this study have been published in the journal Cancer Research.

GIS study sheds light on complex regulation of gene expression

Genome Institute of Singapore's (GIS) Associate Director of Genomic Technologies, Dr Yijun RUAN, led a continuing study on the human genome spatial/structural configuration, revealing how genes interact/communicate and influence each other, even when they are located far away from each other.

Scientists reveal novel mechanism underpinning age-dependent changes to cognitive abilities

New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we grow older.

Researchers identify mechanism that leads to ischemia-reperfusion damage

For patients with incurable pulmonary conditions, a lung transplantation is the only available treatment option. However, suitable donor organs are scarce, and even getting them to prospective recipients is not easy. As Professor Alexander Dietrich of the Walther Straub Institute of Pharmacology and Toxicology at LMU explains, "An isolated lung which is no longer perfused with blood can become so severely damaged that it is no longer functional. This so-called ischemia-reperfusion injury is one of the major problems in the field of lung transplantation."

Scientists establish HCV infection in liver-like cells derived from iPSCs

Hepatitis C, an infectious disease that can cause inflammation and organ failure, has different effects on different people. But no one is sure why some people are very susceptible to the infection, while others are resistant. Scientists believe that if they could study liver cells from different people in the lab, they could determine how genetic differences produce these varying responses. However, liver cells are difficult to obtain and notoriously difficult to grow in a lab dish because they tend to lose their normal structure and function when removed from the body.

Researchers reveal how antipsychotics affect metabolism by SMAD3 activation

In a paper published January 31 in the journal Molecular Psychiatry, researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) reveal how antipsychotic drugs interfere with normal metabolism by activating a protein called SMAD3, an important part of the transforming growth factor beta (TGFbeta) pathway.

Intra-arterial technique of stem cell transplantation may enhance functional recovery from TBI

Experiments in brain-injured rats show that stem cells injected via the carotid artery travel directly to the brain, where they greatly enhance functional recovery, reports a study in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Gene activity may help explain how vigorous exercise improves survival from prostate cancer

Scientists at the University of California, San Francisco (UCSF) have identified nearly 200 genes in the healthy prostate tissue of men with low-grade prostate cancer that may help explain how physical activity improves survival from the disease.

ImmunoCellular receives U.S. patent allowance for cancer stem cell treatment

ImmunoCellular Therapeutics, Ltd., a biotechnology company focused on the development of novel immune-based cancer therapies, announced the allowance of U.S. patent claims related to the Company's method of treating glioblastoma multiforme (GBM) in a patient by targeting cancer stem cells.

Abnormal tau protein propagates along linked brain circuits

For decades, researchers have debated whether Alzheimer's disease starts independently in vulnerable brain regions at different times, or if it begins in one region and then spreads to neuroanatomically connected areas. A new study by Columbia University Medical Center (CUMC) researchers strongly supports the latter, demonstrating that abnormal tau protein, a key feature of the neurofibrillary tangles seen in the brains of those with Alzheimer's, propagates along linked brain circuits, "jumping" from neuron to neuron.

Healthy lung tissue transplantation shows promise for patients with pulmonary diseases

For patients suffering from severe pulmonary diseases including emphysema, lung cancer or fibrosis, transplantation of healthy lung tissue may offer the best chance for survival. The surgical procedure, however, faces two primary challenges: an acute shortage of donor lungs and rejection of transplanted tissue by the recipient's immune system.
