Researchers Find How Two Cancer Genes Interact To Cause Malignancy
..., in cells with mutated ras, it took 50 minutes to degrade half of themyc protein. Myc protein's half-life is longer because the mutated ras proteininterferes with the cell's natural degradation of myc protein, much likeclogging a sink. As the myc protein accumulates, the cells continue to divideafter they...Degrading Plastics To Reduce Waste
Plastic bags that degrade in as little as 55 days after use can now be madeusing the first 100% degradable polyethene. The material, called SPI-TEK, couldhelp to increase the capacity of landfill sites by as much as 20-30% bydegrading rapidly and allowing other organic mater...Bullying Behavior: Blame It On Bad Genes?

... poultry. Loganathan notes that the human body can degrade butyltins fairly efficientlyandeliminates them in 24 - 48 hours. However, previous studies in rats have shownbutyltins to have various toxic effects, including disruption of the immunesystem. Loganathan says his current study, using blood cells from...UV Radiation Induces Vitamin A Deficiency In Skin
..." Voorhees explained. "These MMPs break apart and degrade collagen andelastin, the major structural materials in skin. Although the broken-downcollagen and elastin are replaced, the repair process is imperfect. Thisimperfect repair results in a tiny defect in the skin. With repeated UVexposures, the defe...Bacteria That Gorge On Rotting Waste Can Break Down DDT
...robic and aerobic conditions for local bacteria to degrade thepesticides. In a year-long test at an old pesticide factory in Tampa, Florida,AstraZeneca's process, called Xenorem, cut DDT levels in the soil by more than95 per cent. DDT is considered one of the worst pollutants because its breakdownpro...Urban Restorer Sees Trash Trees, Beetles As Signs Of Hope

...es, a family of 14cysteine proteases, enzymes that degrade critical cellular proteins. Seven ofthese are known to be involved in apoptosis. Dr. Alnemri and his co-workersdiscovered many of the caspases themselves. In the Nature paper, the researchers focused their attentions on betterunderstanding th...H.pylori bacteria and their human hosts
...These bacteria release molecules that irritate and degrade epithelial cells,which creates food for the bacterial colony.
