Researchers at Brown University and Hasbro Children’s Hospital have traced the molecular interactions that allow the protein survivin to escape the nucleus of a breast cancer cell and prolong the cell’s life. The study may help in the development of better therapies and prognostics. If the fight against breast cancer were a criminal investigation, then the proteins survivin, HDAC6, CBP, and CRM1 would be among the shadier figures. In that vein, a study to be published in the March 30...

Switch may release fuel and materials for rapid growth and formation of layers that later become organs Shortly after a mouse embryo starts to form, some of its stem cells undergo a dramatic metabolic shift to enter the next stage of development, Seattle researchers report today. These stem cells start using and producing energy like cancer cells. This discovery is published today in EMBO, the European Molecular Biology Organization journal. "These findings not only have implications...

Using state-of-the-art technology, scientists at the Novo Nordisk Foundation Center for Protein Research at the University of Copenhagen and their international collaborators have successfully obtained "molecular snapshots" of tens of thousands processes involved in DNA damage repair. On a daily basis this restoration keeps cells healthy and prevents the development of cancer. The results of this study will help unravel exactly how cells repair their broken DNA, how chemotherapy affects...

In the beginning – of the ribosome, the cell's protein-building workbench – there were ribonucleic acids, the molecules we call RNA that today perform a host of vital functions in cells. And according to a new analysis, even before the ribosome's many working parts were recruited for protein synthesis, proteins also were on the scene and interacting with RNA. This finding challenges a long-held hypothesis about the early evolution of life. The study appears in the journal PLoS ONE....

Researchers at the UCLA stem cell center and the departments of chemistry and biochemistry and pathology and laboratory medicine have identified, for the first time, a generic way to correct mutations in human mitochondrial DNA by targeting corrective RNAs, a finding with implications for treating a host of mitochondrial diseases. Mutations in the human mitochondrial genome are implicated in neuromuscular diseases, metabolic defects and aging. There currently are no methods to successfully...
