Maternal obesity can program fetal brain to induce adult-onset obesity

Researchers at the University at Buffalo have found that fetuses of obese mother rats were programmed in utero to develop obesity in adulthood.

Brain development takes an unexpected bend

Organs, such as the brain or the heart, are not simply collections of the correct types of cells that are required for their function. If these cells are not organized and shaped properly, the organ simply does not function. One crucial part of this organization is to bend sheets of connected cells ("epithelia") so that they form a structure that is an integral part of the functional organ.

Targeting epigenetic changes helps tackle MLL-AF4 leukemias

A very difficult-to-treat child leukemia may benefit from the discovery of a small but potent epigenetic change that launches the cancer - but could potentially be reversed relatively easily, preventing cancer-promoting genes from being turned on.

Genetic mutation linked to seasonal affective disorder

With the days shortening toward winter, many people will begin to experience the winter blahs.

Adding protein sarcospan to muscle cells might help Duchenne muscular dystrophy

The overlooked and undervalued protein, sarcospan, just got its moment in the spotlight.

Human papillomavirus helps cervical and head and neck cancers resist treatment and grow and spread

The human papillomavirus (HPV) allows infected cervical and head and neck cancer cells to maintain internal molecular conditions that make the cancers resistant to therapy and more likely to grow and spread, resulting in a poor prognosis for patients, researchers with UCLA's Jonsson Cancer Center found.

No need for RNA

Not all enzymes that are assumed to require an RNA component in order to function do actually contain RNA. This surprising discovery was made during a project supported by the Austrian Science Fund FWF that focussed on the enzyme RNase P.

Genentech submits application to FDA for Avastin in the most aggressive form of brain cancer

Genentech has announced that the company submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for Avastin (bevacizumab) as a therapy for people with previously treated glioblastoma. If accepted by the FDA, the application would be considered for an accelerated approval that allows provisional approval of medicines for cancer or other life-threatening diseases based on preliminary evidence suggesting clinical benefit.

Without glial cells, animals lose their senses

Sensory neurons have always put on a good show. But now it turns out they'll be sharing the credit. In groundbreaking research to appear in the October 31 issue of Science, Rockefeller University scientists show that while neurons play the lead role in detecting sensory information, a second type of cell, the glial cell, pulls the strings behind the scenes.

How the Nodal gene family keeps the heart in the right (asymmetric) place

Asymmetry is crucial for the heart proper functioning, and now, scientists from the Institute Gulbenkian of Science in Portugal and Harvard University, have discovered that a family of genes, called Nodal, is crucial determining this asymmetry by controlling the speed and direction of the heart muscle cells during embryonic development.

New method provides panoramic view of protein-RNA interactions in living cells

DNA, it has turned out, isn't all it was cracked up to be. In recent years we learned that the molecule of life, the discovery of the 20th century, did not - could not - by itself explain the huge differences in complexity between a human and a worm.

Double-barreled immune cell approach for neuroblastoma

Adding an artificial tumor-specific receptor to immune system cells called T-lymphocytes that target a particular virus extended and improved the cells' ability to fight a form of childhood cancer called neuroblastoma, said researchers form Baylor College of Medicine and Texas Children's Hospital in a report that appears online in the journal Nature Medicine.

Scientists develop genome-wide platform to study how specialized proteins regulate RNA in living, intact cells

DNA, it has turned out, isn't all it was cracked up to be. In recent years we learned that the molecule of life, the discovery of the 20th century, did not -- could not -- by itself explain the huge differences in complexity between a human and a worm.

Alternative splicing in genes more prevalent than previously believed

Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA.

Gleevec holds potential as first drug to successfully treat neurofibromatosis

Researchers at the Indiana University School of Medicine report that the anti-cancer drug Gleevec holds out promise to become the first effective treatment for neurofibromatosis, a genetic disease that has resisted treatments until now.

By imaging live cells, researchers show how hepatitis C replicates

The hepatitis C virus is a prolific replicator, able to produce up to a trillion particles per day in an infected person by hijacking liver cells in which to build up its viral replication machinery.

New grant for blood substitutes

Researchers in the Department of Biological Sciences at the University of Essex have been awarded almost £115,000 to develop a life-saving blood substitute.

Drinking milk to ease milk allergy?

Giving children with milk allergies increasingly higher doses of milk over time may ease, and even help them completely overcome, their allergic reactions, according to the results of a study led by the Johns Hopkins Children's Center and conducted jointly with Duke University.

Rice can trigger a severe allergic reaction in babies

According to new research by Australian doctors, contrary to the current view of it as a hypo-allergenic foodstuff, rice can trigger a severe allergic reaction in babies.
