... published in the July 9 issue of the journal Cell describes how the researchers engineered mutations to 700 of the 1,000 yeast genes that are essential to cell life. They analyzed the mutant strains by making several basic measurements -- cell size, cell shape and gene levels and by evaluating a cell's poten...Access to DNA secrets yields better understanding of genes, possible tool for disease diagnosis
...ve of cancer or other diseases. "Our current study describes the platform technology necessary to try to understand larger questions," Dr. Garner said. "The next step will involve using the technique to look at different types of cancer cells to see whether this type of assay could be a diagnostic tool."

Chen describes Akt as an important molecular switch that transmits information from the cell surface down into the cell to interact with a variety of target molecules. He and colleagues further found that the blocking of Akt by celecoxib in cancer cells triggered p...UNC scientists discover molecular pathway leading to nerve growth and regeneration

...journal Cell, the research team headed by Weinberg describes how a breast carcinoma in mice misappropriates a protein called Twist. Twist is a gene regulator, meaning that it tells genes when to turn on and when to turn off. But Twist is mainly active in early embryonic development, where it enables cells to m...New computational tools to aid in protein research
