Researchers unlock mechanism creating jigsaw puzzle-like plant cells

...and slenderness, provide the strength necessary to allow the plant to grow and thrive. The findings point out that these distinct signals play a critical role in the development of leaf cell walls and leaf structures in a controlled and ordered way and that genetically over expressing one or the other lea...

New understanding of DNA repair may pave way to cancer treatments

Insight into DNA's 'weakest links' may yield clues to cancer biology

...Duke, first author of the study. "The finding will allow us to develop a simple model to study fragile sites in a way that can't be done in more complex organisms." The findings suggest that mammalian and yeast fragile sites may have common features, an indication that a common mechanism may underlie thei...

Maine Researchers Find Exceptions to Old Rules of Genetic Inheritance

...t than mapping the genome. The haplotype map could allow researchers to look for a single variation in the complex genetic code and know all the variations associated with it, since all are part of the same haplotype. The Maine research group challenges that proposal, demonstrating that genes within a hap...

Biochemists report discovery of structure of major piece of telomerase; implications for cancer

...e research group. "Knowing the structure also will allow the pursuit of rational, structure-based drug design, and is a critical first step. The structure provides a potential target for drug intervention." Feigon emphasized that her laboratory conducts basic research, and is not involved in cancer treatm...

Scientists discover that three overlapping signals in embryo help get the backbone right

Protein Discovery Could Unlock The Secret To Better TB Treatment

...id: "The discovery of Rpf in the TB bacteria could allow the development of methods to 'wake-up' all dormant bacteria in a patient allowing antibiotics to kill the bacteria and cure the disease." The team includes Prof Brian Henderson at the UCL Eastman Dental Institute, Nicholas Keep from Birkbeck, Unive...

South African Tribunal Asks For Damages Estimates in GSK AIDS Drug Case

...k by South Africa's Competition Tribunal that will allow the complaint to go forward. GSK has sought outright dismissal of the case; however, the Competition Tribunal issued an order last week giving the complainants, AIDS Healthcare Foundation (AHF) and several South African AIDS advocates, 10 days to pre...

"For example, a channel modification project should minimise loss of native vegetation during river reconstruction, and should avoid the fish spawning ...

Protein prevents detrimental immune effects of bacterial sepsis

... way our body controls responses to infections can allow the modeling of new therapeutics with lower side effects." The importance of this work is underscored by the fact that bacterial sepsis ranked among the top ten causes of death in both adults and neonates in 2002 in the United States (Natl Vital Sta...

Measuring Enzymes At End Of Cancer Pathway Predicts Outcome Of Tarceva, Taxol

...f enzymes, which are the triggering molecules that allow a cell to grow and divide. CDK cell cycle enzymes are the end target of numerous cellular pathways that are involved in cancer development and progression, the researchers say. Before these studies, no one has been able to accurately test the functi...

The lopsided brain: Attention bias is shared by humans and birds

The findings are reported in the May 24 issue of Current Biology by Bettina Diekamp (now at Johns Hopkins University) and colleagues at Ruhr University, Bochum, Germany; the Unive...

Findings have implications for tracking disease, drugs at the molecular level

...ousands or millions of stain molecules. This could allow us, for instance, to track a single molecule of a drug in a cell or other biological sample." Other advantages of the technique are that the gold particles can be prepared easily, have very low toxicity, and can readily be attached to molecules of b...
