Hormone helps mice 'hibernate,' survive starvation

...eir metabolism and “hibernate” to conserve energy, revealing a novel molecular target for drugs to treat human obesity and metabolic disorders, UT Southwestern Medical Center researchers have found. The starvation-fighting effects of the hormone, called fibroblast growth factor 21 (FGF21), are described for...

Women well informed about breast cancer, yet lacking knowledge about current treatments

...-65 have heard of new therapies for breast cancer, revealing a gap between awareness and information that women can use toward better treatment. “These survey results suggest that many women still lack essential disease treatment information, which reinforces the need for women to educate themselves ...

Mutating the entire genome

...bled or “knocked out” to see what goes wrong, thus revealing the gene’s normal function and how disease makes it malfunction. But DNA regulatory sequences between genes also can mutate to cause disease by making the genes they control malfunction. “We know how to knock out genes, and that technology is ver...

Better insight into brain anatomical structures

...c resonance imaging is a very effective method for revealing anatomical details of soft tissues. Contrast agents can help to make these images even clearer and allow physiological processes to be followed in real time. Conventional gadolinium complexes currently used as MRI contrast agent cannot reveal anatomi...

Philandering female felines forgo fidelity

... than one cub were fathered by more than one male, revealing a mating system that deviates from those used by other carnivores, most of which consist of single or sibling males monopolizing many females. “It seems that female cheetahs are highly promiscuous with no detectable mate fidelity between breeding ...

DOE JGI sets 'gold standard' for metagenomic data analysis

...n is transitioning from single-organism studies to revealing the potential biotechnology applications embedded in communities of microbial genomes, or metagenomes. The field of metagenomics is still in its infancy -- the equivalent of the early days of the California Gold Rush, with labs vying to stake their ...

Executable biology -- Computer science sheds light on animal development

...e model can then be compared to data from the lab, revealing gaps in our understanding of the processes taking place. Researchers can use the model to test hypotheses that would fill in the missing pieces in silico before performing actual lab experiments. By running their model with a wide variety of gene ...

Loss of a universal tRNA feature reported

...position in the tRNAHis precursor. It will also be revealing to see how different aminoacyl-tRNA synthetases have adapted to discriminate between their cognate or related substrates and the now less distinctive tRNAHis." ...

Reading hidden intentions in the human brain

...he correct answer according to their planned task, revealing their intended action. The researchers found that during the delay between the subjects' choice of task and execution of the task, it was possible to decode from activities in two regions of the prefrontal cortex which of the two actions (addition...

New protein inhibitor impedes growth of cancerous cells

...fic points during the cell-division cycle, thereby revealing the normal roles of Plk1 in new detail, and potentially identifying specific cellular processes that might be targeted by future anti-cancer therapeutics. ...

Technology reveals 'lock and key' proteins behind diseases

...chnology developed at the University of Toronto is revealing biochemical processes responsible for diseases such as cystic fibrosis and could one day pave the way for pharmaceutical applications. A study appearing in the April 13 issue of Molecular Cell describes how U of T and Johns Hopkins University resea...

Microbes start immune response by sneaking inside cells

...tors on a cell’s surface. But, now new studies are revealing that bacteria can also plunge inside immune system... The team’s work joins a growing body of research revealing the importance of recently discovered receptors such as cryopyrin inside cells, known collectively a...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

...ost common sexually transmitted infections (STIs), revealing potential clues as to why the parasite has become increasingly drug resistant and suggesting possible pathways for new treatments, diagnostics and a potential vaccine strategy. The genome sequencing project, funded by the National Institute of Allerg...

UBC researchers reveal dwarf aquatic plants' hidden ancestry

...rles Darwin once termed an ‘abominable mystery??by revealing that some of the earliest evolutionary branches were more diverse then we once thought." ...

Non-GMO solution to seafood allergies

...am suggests that irradiation damages the proteins, revealing hidden reactive amino acid residues. Subsequent heating then destroys the exposed residues. "Radiation and heat seems to be a promising method for reducing the immunoreactivity" say the researchers. Samuel Lehrer of Tulane University in New Orlean...

Major link in brain-obesity puzzle found

...s Research and Training Center. In addition to revealing the importance of SH2B1 activity in the brain, the new paper shows that SH2B1 is expressed in four different forms in many tissues of the body, including fat cells known as adipose tissue, as well as the liver, heart, pancreas and muscle. Rui and...

Preliminary study finds holographic imaging system promising for cancer treatment planning

... full-motion system can display images of the body revealing the exact location of tumors in true 3D space. A study led by Rush, which also included Tufts-New England Medical Center, and Rhode Island Hospital/Brown Medical School, found the Perspecta has significant potential to achieve better quality in ra...

NHGRI aims to make DNA sequencing faster, more cost effective

...anometer-scale pore is driven by an electric field revealing information about the DNA sequence. This method has the potential to become an inexpensive, ultrafast DNA sequencing technique. Most nanopore sequencing approaches involve either the protein pore alpha-hemolysin or artificial pores in inorganic mater...

Comments, experts and background on the 2006 Nobel Prize in chemistry

...netics. In order to take the first actual pictures revealing how the genetic information stored in genes is copied so that the body can use it, Dr. Kornberg used a mainstay chemical technology called x-ray crystallography. "Chemistry has had a key role from the very onset of the genetics revolution. It has p...

New technique boosts size of proteins that can be analyzed

...re confident identifications; it is also better at revealing modifications and mutations, where there might be a mistake or addition in the sequence. The new approach can also provide sequence information on a protein from scratch when it is not present in any database. ...
