Converting white fat cells into beige fat cells could help fight obesity

The body's ability to harness heat production by converting white fat cells, which store calories, into beige fat cells, which burn energy, could help fight obesity, according to researchers at Georgia State University.

Researchers find new way to prevent or reduce pathologies caused by malformed proteins

Improperly formed proteins can cause a host of serious illnesses, from muscular dystrophy to cystic fibrosis. A question of enormous import in research, beyond the challenge of determining how malformed proteins contribute to specific disease processes, is figuring out ways to prevent or reduce the pathologies they cause.

Whitehead researchers create 3D map to predict how genes are regulated in normal cells

Whitehead Institute researchers have created a map of the DNA loops that comprise the three dimensional (3D) structure of the human genome and regulate gene expression in human embryonic stem (ES) cells and adult cells. The location of genes and regulatory elements within this chromosomal framework could help scientists better navigate their genomic research, establishing relationships between mutations and disease development.

Study reveals molecular function of protein essential for replication of H5N1 flu virus

An international collaboration of scientists from the CEA, CNRS, University Joseph Fourier, the EMBL and the ILL has revealed the molecular function of a protein essential for replication of H5N1 influenza virus.

NEK7 enzyme acts as on-off switch in innate immune system

UT Southwestern Medical Center and California researchers today provide the first report that an enzyme previously known solely for its role in cell division also acts as an on-off switch in the innate immune system -- the body's first defense against infection.

Study reveals how MGCs dispose waste that obstructs normal physiological processes

If rubbish is too big and unwieldy for normal household waste, its removal becomes the job of specialized experts. Researchers from the Technical University of Munich (TUM) have now discovered, in cooperation with colleagues from the UK, how large, fused cells help our body to deal with bulky items that may otherwise obstruct normal physiological processes.

Research shows how scientists altered stem cells, triggered bone growth

Imagine you have a bone fracture or a hip replacement, and you need bone to form, but you heal slowly - a common fact of life for older people. Instead of forming bone, you could form fat. Researchers at the University of North Carolina School of Medicine may have found a way to tip the scale in favor of bone formation. They used cytochalasin D, a naturally occurring substance found in mold, as a proxy to alter gene expression in the nuclei of mesenchymal stem cells to force them to become osteoblasts (bone cells).

Presence of connexin proteins suppresses primary tumor growth

How does a protein called connexin put the clamps on cancer? Researchers in the School of Medicine at The University of Texas Health Science Center at San Antonio today reported an explanation.

New findings reveal association between colorectal cancer and melanoma drug treatment

Veteran cancer reseacher Prof. Emeritus Alexander Levitzki of Hebrew University of Jerusalem says new findings show link between colorectal cancer and melanoma drug treatment knoqwn as "NT157" in two recently published studies in journal, "Ocogene."

Scientists create supercharged blood cell that may heal major wounds, block inflammation

Faculty of Medicine scientists have created a "Franken-platelet" - a supercharged blood cell - that might be capable of healing major wounds, busting clots or blocking inflammation.

Scientists identify new jelly-like properties of essential proteins that lead to serious diseases

Scientists at the University of Cambridge have identified a new property of essential proteins which, when it malfunctions, can cause the build up, or 'aggregation', of misshaped proteins and lead to serious diseases.

Nuclear membrane fixes potentially fatal breaks in DNA strands

Scientists have found a new function of the nuclear membrane, the envelope that encases and protects DNA in the nucleus of a cell - it fixes potentially fatal breaks in DNA strands.

New research shows that autophagy can operate in cell nucleus to guard against start of cancer

Autophagy, literally self-eating or the degradation of unwanted cellular bits and pieces by the cell itself, has been shown for the first time to also work in the cell nucleus. In addition, in this setting it plays a role in guarding against the start of cancer, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Love hormone may enhance pleasure of social interactions, UCI study finds

The hormone oxytocin, which has been associated with interpersonal bonding, may enhance the pleasure of social interactions by stimulating production of marijuana-like neurotransmitters in the brain, according to a University of California, Irvine study.

Thalamic reticular nucleus responsible for the brain's ability to multitask, study reveals

Researchers at NYU Langone Medical Center say they have added to evidence that a shell-shaped region in the center of the mammalian brain, known as the thalamic reticular nucleus or TRN, is likely responsible for the ability to routinely and seamlessly multitask.

Scientists map out the brain circuitry critical for filtering out distractions

In a study of mice, scientists discovered that a brain region called the thalamus may be critical for filtering out distractions. The study, published in Nature and partially funded by the National Institutes of Health, paves the way to understanding how defects in the thalamus might underlie symptoms seen in patients with autism, attention deficit hyperactivity disorder (ADHD), and schizophrenia.

Active nuclear deformations contribute to formation of intra-nuclear chromosome architectures

There are two types of chromatin, euchromatin and heterochromatin, that vary with the stages of the cell cycle. In particular, euchromatin with rich active genes localizes to the interior of the nucleus during interphase; heterochromatin usually localizes to the periphery of the nucleus.

Melatonin and the circadian rhythm: an interview with Professor Kennaway, University of Adelaide

The production of melatonin is controlled by a part of the brain called the suprachiasmatic nucleus (SCN) and its timing fine-tuned by our exposure to light during the morning.

Genetic mutation linked to ALS, FTD prevents proteins from entering and exiting the cell's nucleus

Three teams of scientists supported by the National Institutes of Health showed that a genetic mutation linked to some forms of amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD) may destroy neurons by disrupting the movement of materials in and out of the cell's nucleus, or command center where most of its DNA is stored.

Researchers identify molecular switch that can avoid inflammation

Our immune system is vital to us and can sometimes overreact causing chronic illnesses, such as for instance rheumatism and allergy. Now, researchers from Umeå University and University of Gothenburg have identified a molecular switch - MYSM1 - that can suppress such an overreaction and avoid inflammation.
