Protein involved in cell division now found key to cell growth
...mes, or if there is just too little ARF protein to degrade high levels of B23 protein. "B23 has been found to be highly over-expressed in many tumors, such as in breast and ovarian cancers, but no one knows why that is or how to control it," says Zhang. "Now we at least know that ARF can control B23, and it...Researchers find mechanism bacteria use to target specific chemical contaminants
...ially means that in order for bacteria to grow and degrade an organic contaminate, it must be able to 'breathe' on something other than oxygen." The researchers hope to one day be able to tailor bacteria so it could target a specific contaminant. Lower pointed out that one problem with using microbes to help...Tools from the Human Genome Project reveal a versatile microbe

...rs as well as smaller nanoparticles -- that could degrade even faster in the body and offer different drug delivery options, he said. Quick degradation also could help avoid uptake by organs not intended to receive the particles, he said, a possible negative side effect of the process.

...nisms attach themselves to the chitin? How do they degrade the tough material and turn it into food? During the past decade, Roseman and his colleagues have made several advances in answering these questions. In the new PNAS paper, Li and Roseman reported that they had identified and isolated the bacteria...Enzyme fully degrades mad cow disease prion

...chlorophyll molecules themselves normally begin to degrade at about 167 degrees, according to Schlesinger, who is a biogeochemist and ecologist.

There is a high probability that peregrine falcons in North America could face a similar risk from deca exposure, de Wit notes. "According to statistics from 1999, 24,300 tons of deca were used in the America...A killer microbe as a living antibiotic
...m uses a large variety of lytic enzymes, which can degrade complex biopolymers of the prey, such as proteins, carbohydrates, DNA and RNA. The researchers will attempt to identify the targets in the prey cell that have proven to be successful points of attack in this million-year-old prey-predator relationshi...University of Delaware lays keel for new research vessel
