Attacking cancer's sweet tooth is effective strategy against tumors

... more, they continue to use this pathway even when access to oxygen is restored. Though the so-called Warburg effect has since been confirmed, the role played by glycolysis in cancer has been largely ignored. Few have attempted to attack specific points along the glycolytic pathway to gain a therapeutic ef...

Newly identified protein complex sheds light on axon growth mechanism

... C.elegans. In a study published today in the open access journal Journal of Biology, researchers have characterised a new protein, UNC-69, required for proper locomotion . They show that UNC-69 interacts with UNC-76 in a protein complex likely to be involved in the trafficking of vesicles along axons - a p...

Key to early diagnosis of autism may be in the placenta

...h scientist in the Yale Child Study Center who had access to many cases of children with ASD," said Kliman. "We realized that by working together we might be able to determine if this placental abnormality could be a useful clinical marker." With the help of Andrea Jacobs-Stannard, a student in Kliman's la...

DOE JGI sequences, releases genome of symbiotic tree fungus

Such mycorrhizae are critical to terrestrial ecosystems, Martin said, since approximately 85 percent of all plant species, including trees, are dependent on such interactions to thrive. Mycorrhizae significantly i...

Cigarette smoke blocks cell repair mechanism, University of Florida study shows

...ix their damaged DNA, many others become unable to access their own cellular first aid kit, according to findings from a UF study published today (Aug. 21) in the journal Oncogene. If they survive long enough to divide and multiply, they pass along their mutations, acquiring malignant properties. Past res...

MIT 'seeing machine' offers hope to blind

Recently the machine received positive feedback from 10 visually challenged people with a range of causes for their vision loss who tested it in a pilot clinical tria...

Researchers develop flood-tolerant California rice

Bailey-Serres notes that access today to information about the rice genome ?all the genetic material in the chromosomes of rice ?has greatly accelerated progress in identifying specific genes that confer specific traits. "Currently, the International Rice Research Institute is acti...

Use of stone hammers sheds light on geographic patterns of chimpanzee tool use

...e stone hammers to crack open hard-shelled nuts to access the nutrient-rich seeds. The findings are significant because this nut-cracking behavior was previously known only in a distant chimpanzee population in extreme western Africa and was thought to be restricted by geographical boundaries that prevented...

CHAVI announces international search for genes affecting HIV response

...ompeted to unravel the mysteries of HIV will share access to patient groups, called cohorts, they have studied. Support for the consortium is provided by the Center for HIV/AIDS Vaccine Immunology (CHAVI), established at Duke in 2005 with a grant that could total as much as $300 million over seven years fr...

Scientists discover a genetic code for organizing DNA within the nucleus

...tant role in the cell's day to day function, since access to DNA wrapped in a nucleosome is blocked for many proteins, including those responsible for some of life's most basic processes. Among these barred proteins are factors that initiate DNA replication, transcription (the transfer of genetic informatio...

Life and death in the hippocampus: what young neurons need to survive

...t animals in an enriched environment and give them access to running wheels, you increase survival of new brain cells," says Gage. "Now we show that stimulation may, in part, be mediated through the NMDA receptor." Those studies had also shown that young and middle-aged "exercised" rats perform better on ...

Molecular DNA switch found to be the same for all life

...s makes it difficult for these protein machines to access the DNA. Because of this complexity, the mechanism for initiating DNA replication in eukaryotes was presumed to be much different than the prokaryote initiator. Studies over the past decade have demonstrated that all of the multiple events that ...

In a study published today in the open access journal BMC Biology, vampire bats of the species Desmodus rotondus could recognise recorded human breathing sounds much better than human participants could. Vampire bats feed on the same prey over several nights and the authors of the study propose ...

Beekeepers work hard for the honey, despite changing tupelo forest
