Ten years ago, researchers at the IMP - a basic research institute in Vienna - discovered a fundamental and amazingly plausible mechanism of cell division. They identified a protein complex, which, as a ring-shaped molecule, slides over the doubled chromosomes and holds precisely these together until the time they again separate.

Researchers in Belgium have significantly advanced the discovery of a pancreatic progenitor cell with the capacity to generate new insulin-producing beta cells. If the finding made in mice holds for humans, the newfound progenitor cells may represent “an obvious target for therapeutic regeneration of beta cells in diabetes,” the researchers report in the Jan. 25 issue of the research journal Cell, a publication of Cell Press.

Genetically engineered products have become indispensable. For example, genetically modified bacteria produce human insulin. In future, gene therapy should make it possible to introduce genes into the cells of a diseased organism so that they can address deficiencies to compensate for malfunctions in the body. In order for this to work, foreign (or synthetic) DNA must be introduced into host cells, which is not exactly a trivial task.

New research links the recently discovered function of a multi-faceted transcriptional complex to control of gene expression in both normal cells and cancer stem cells.

University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells.

Many researchers have tried to create a mathematical model of how cells pack together to form tissue, but most models have many different complicated factors and no model is universal.

A group of scientists in Princeton's Department of Ecology and Evolutionary Biology has uncovered a new biological mechanism that could provide a clearer window into a cell's inner workings.

Even small mistakes made by cells during protein production can have profound disease effects, but the processes cells use to correct mistakes have been challenging to decipher. Recent work by scientists at The Scripps Research Institute, however, has uncovered two surprising new methods for such editing.

Genome rearrangements, resulting in variations in the numbers of copies of genes, occur when the cellular process that copies DNA during cell division stalls and then switches to a different genetic “template,” said researchers at Baylor College of Medicine in Houston in a report that appears today in the journal Cell.

Cells keep a close watch over the transcriptome – the totality of all parts of the genome that are expressed in any given cell at any given time. Researchers at the Salk Institute for Biological Studies and the University of Missouri-Kansas City teamed up to peel back another layer of transcriptional regulation and gain new insight into how genomes work.

The Stowers Institute’s Baumann Lab has identified the long-sought telomerase RNA gene in a single-cell research model. Their findings have been posted to the Web site of the journal Nature Structural & Molecular Biology and will appear in a future print edition.

Researchers have solved the structure of a DNA-protein complex that is crucial in the spread of antibiotic resistance among bacteria. Knowing this structure also provides fundamental insight into how cells successfully divide into two new cells with intact DNA
