Researchers discover transport molecule that allows boron into cells
...s at UT Southwestern Medical Center at Dallas have identified
a protein that transports the essential nutrient boron into cells, where it is important for cell growth and bone development. The findings are in the Nov. 5 edition of the journal Molecular Cell and are online. The protein, NaBC1, is found in m...
U-M researcher examines the cell's housekeeping habits
... Genes governing Type II PCD, autophagy, have been identified
recently in many species, starting with baker's yeast, and some of the environmental triggers that start the process are being found. But there is still quite a bit of science to do before autophagy can be understood as either a good thing or a bad t...
Powerful 'toolkit' developed for functional profiling of yeast genes
...he end of an experiment, each mutant in the mix is identified
by a genetic "barcode" -- created by Shoemaker -- ... In one set of experiments, the new technique identified
116 genes that were synthetic lethal with a gene called cin8 and confirmed their involvement. Of the...
A new target for control of obesity
...stance. In 2003, the World Health Organization identified
obesity as a growing global threat affecting more than 300 million people worldwide. Although it is commonly believed that obese individuals can overcome their condition by simply eating less and exercising more, compelling scientific data suggest t...
For yeast, a DNA break ensures sex switch for a grandchild
...oup at the Pasteur Institute in Paris, France, has identified
a new imprinting mechanism that controls sexual switching in yeast. The French group has now demonstrated that the genomic DNA at the mating-type locus of the yeast Schizosaccharomyces pombe is marked by a simple break on one strand of the DNA. O...
Molecular switch provides clues to remarkable adaptability of human pathogen
Scientists have identified
a gene that may play a key role in the ability of an important human pathogen to sense and adjust to its surroundings. The research, published in the November issue of Developmental Cell, provides new evidence about how bacteria regulate gene expres...
Conversion of flower organs into leaves

such a gene. The gene, SEP4, is closely related to the three genes corresponding to the triple mutan...
Grants target better predictors for type 1 diabetes
...vised estimate of 20,000 to 25,000 human genes and identified
about 100 genes that may predict type 1 diabetes. The new Juvenile Diabetes Research Foundation Grant will help validate those findings. "Because these 100 genes are different in people with diabetes as well as pre-diabetics versus controls, we be...

the arthropod as Lioestheria disgregaris, and it appears to have been a bivalved arthropod similar i...
MIDI, Inc receives Official Methods(SM) status for the confirmatory ID of the anthrax pathogen
... in the bacterial cell membrane. The bacteria are identified
by comparing their fatty acid "fingerprint" to databases of known fatty acid patterns. The system includes several bacterial databases, including The MIDI BIOTER TM database (version 2), which was exclusively used in the study. The MIDI Sherlock S...
Reduced fish stocks linked to increased bushmeat trade, wildlife declines in W. Africa
...C fisheries professor Daniel Pauly and others have identified
the Gulf as one of the most overfished areas of the world, and now at risk of collapse. Declines in fish stocks in waters off West Africa have coincided with more than ten-fold increases in regional fish harvests by foreign and domestic fleets since...
Lyme disease receptor identified in tick guts
Researchers at Yale School of Medicine have identified
a Lyme disease receptor called TROSPA that is used... Lyme disease pathogens survive inside ticks. "We identified
a receptor inside the tick gut that the spirochete bacteria use to colonize or invade ticks," said p...
Discovery reveals how the body regulates blood oxygen
... and where it is needed most." The scientists have identified
an oxygen-sensing protein, which in mammals is located in a cluster of cells at the spot where the carotid artery branches in the neck. It senses oxygen levels in the blood flowing by and helps the brain to adjust the breathing rate accordingly. "Wh...
UCSD discovery opens new avenues for design of anti-tumor medications
...biology at UCSD who headed the research team. "We identified
a gene that turns on in the cells lining blood vessels when they are not getting enough oxygen and showed that without this gene the blood vessels cannot grow to nourish the developing tumor. Drugs that interfere with this gene, or another gene invo...
New protein identified in development of lung cancer
...3 function in tumors. Villalona and his colleagues identified
the link between Pirh2 and the development of cancer by evaluating Pirh2 expression in human and mouse lung tumor samples and comparing it with Pirh2 expression in normal tissue from the same samples. They found that Pirh2 expression was higher in 27...
