Children with change in SUFU gene more likely to develop brain tumour

Gorlin syndrome causes an increased risk of developing cancers of the skin and, rarely, in the brain. Around 1 in 30,000 people has the condition.

New therapeutic targets can prevent scarring within transplanted kidneys

Kidneys donated by people born with a small variation in the code of a key gene may be more likely, once in the transplant recipient, to accumulate scar tissue that contributes to kidney failure, according to a study led by researchers at the Icahn School of Medicine at Mount Sinai and published today in the Journal of Clinical Investigation.

UT Austin researchers identify network of genes that drives alcohol dependence

Researchers at The University of Texas at Austin have identified a network of genes that appear to work together in determining alcohol dependence. The findings, which could lead to future treatments and therapies for alcoholics and possibly help doctors screen for alcoholism, are being published this week in the journal Molecular Psychiatry.

HIV's ability to cause AIDS is declining, finds new research

The rapid evolution of HIV, which has allowed the virus to develop resistance to patients' natural immunity, is at the same time slowing the virus's ability to cause AIDS, according to new research funded by the Wellcome Trust.

Researchers explore how to turn on the activity of paternal gene

Most genes are inherited as two working copies, one from the mother and one from the father. However, in a few instances, a gene is imprinted, which means that one copy is silenced. This is called genomic imprinting. If the active copy is mutated, then disease results, even though the silenced gene copy may be normal.

Study paves way for further research on brain evolution

The neocortex is the part of the brain that enables us to speak, dream, or think. The underlying mechanism that led to the expansion of this brain region during evolution, however, is not yet understood. A research team headed by Wieland Huttner, director at the Max Planck Institute of Molecular Cell Biology and Genetics, now reports an important finding that paves the way for further research on brain evolution: The researchers analyzed the gyrencephaly index, indicating the degree of cortical folding, of 100 mammalian brains and identified a threshold value that separates mammalian species into two distinct groups: Those above the threshold have highly folded brains, whereas those below it have only slightly folded or unfolded brains.

Study shows how specific trauma changes into a state of generalized fear

"I can't get the memories out of my mind!... I am right back in Vietnam, in the middle of the monsoon season at my guard post. My hands are freezing, yet sweat pours from my entire body...I smell a damp sulfur smell. Suddenly I see what's left of my buddy Troy, his head on a bamboo platter, sent back to our camp by the Viet Cong."

SPLUNC1 protein binds to pulmonary lipids to fight lung infection

Scientists have taken an important step toward a new class of antibiotics aimed at stopping lung infections. They found that a protein found in large airways, called "SPLUNC1," binds to lipids critical to defending against bacterial and viral infections, as well as keeping lung tissue flexible and hydrated.

Commonly used osteoporosis medications may also prevent lung, breast and colon cancers

The most commonly used medications for osteoporosis worldwide, bisphosphonates, may also prevent certain kinds of lung, breast and colon cancers, according to two studies led by researchers at the Icahn School of Medicine at Mount Sinai and published today in the Proceedings of the National Academy of Sciences.

Ligand indazole chloride improves motor function, study shows

Multiple sclerosis (MS), an autoimmune disease of the brain and spinal cord, affects about 2.3 million people worldwide (400,000 in the United States). Affecting more women than men, it can be seen at any age, although it is most commonly diagnosed between the ages of 20 and 40.
