The significance of these newly discovered proteins is also highlighted in the same issue of Science by another paper with similar findings from a different group of researchers. Additional evidence of the proteins' critical role will be offered by a paper slated to appear in a...

... and 500 pounds it is considerably larger than the newly discovered species. The highly endangered tamaraw lives only on the Philippine island of Mindoro. Two poorly known species of the genus Bubalus from the Indonesian island of Sulawesi, known as anoas, are more distantly related. The new species, B....

Jefferson scientists find aging gene also protects against prostate cancer development

...er director Richard Pestell, M.D., Ph.D., hope the newly found connection will aid in better understanding the development of prostate cancer and lead to new drugs against the disease. SIRT1 is a member of a family of enzymes called sirtuins that have far-reaching influence in all organisms, including ro...

New neurons could act to alleviate epilepsy

...tory connectivity. Such differences could mean the newly generated neurons "could have significant beneficial effect on the epileptic syndrome," concluded the researchers. "Our study demonstrates that both a physiological stimulus and an insult to the adult brain trigger the formation of new dentate gra...

Honey bee genome holds clues to social behavior

...social behavior, Sinha and his colleagues used the newly sequenced honey bee genome to scan the binding sites of transcription factors known to function in the development of fruit flies (Drosophila melanogaster) from a single cell to an adult. A computer algorithm written by the researchers scanned near...

New path from estrogen to survival in breast cancer cells described

SENP8, a protease (enzyme) that can break bonds between other molecules. SIRT1 NFkB (Nuclear Factor kappa B), a ...

Scientists identify 36 genes, 100 neuropeptides in honey bee brains

...d by," Sweedler said. Using a combination of the newly available honey bee genome sequence, as well as bioinformatics and mass spectrometry, Sweedler and collaborators from the United States and Belgium inferred the sequences of more than 200 possible neuropeptides and confirmed the sequences of 100 neur...

AIDS study challenges conventional treatment guidelines for HIV patients

A newly published study by investigators at the Center for AIDS Research at Case Medical Center, led by Benigno Rodríguez, MD, along with a nationwide team of AIDS/HIV experts, strongly challenges conventional thinking about the role of measurements of the a...

Parasitic plants sniff out hosts

...ers used a variety of experiments to determine how newly emerging dodder shoots find a host. The length of time these parasites can live without a host is determined by the amount of food stored in the seed, but they can only grow about four inches before they die. "These plants have no roots and barely ...

Genetic 'roadmap' charts links between drugs and human disease

Based on the results, the papers propose a public project to expand this initial human Connectivity Map -- in the spirit of the Human Genome Project -- to accelerate the search for new drugs to treat disease....

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

...ne have been developed so far, says Wolfgang. The newly discovered gene makes a protein found only in the brain, notably in the region that controls hunger, thirst and metabolism - the hypothalamus. Proteins similar to CPT1c are known to help break down fat to release energy to feed cells. Mice lacking ...

New study calculates millions of years saved in lives of AIDS patients

...xamine national surveillance and efficacy data for newly diagnosed adult AIDS patients under care in the United States from 1989 to 2003.

"It's premature to call it a master switch, but intriguingly, it regulates at least four different processes, each of which individually would be anti-angiogenic," says Bresnick.
