Genetic tag team orchestrates the cell cycle

By surveying the activity of thousands of genes at several different time points, researchers at the Duke Institute for Genome Sciences & Policy have uncovered new evidence that a network of influential genes act as a kind of genetic tag team to orchestrate one of the most fundamental aspects of all life: the cell cycle.

Small molecule nutlin-3a activates an important cancer suppressor gene

By activating a cancer suppressor gene, a small molecule called nutlin-3a can block cancer cell division, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health.

Yale scientists explain metastasis

Metastasis, the spread of cancer throughout the body, can be explained by the fusion of a cancer cell with a white blood cell in the original tumor, according to Yale School of Medicine researchers, who say that this single event can set the stage for cancer's migration to other parts of the body.

AMPK signaling helps explain how cell growth is inhibited when nutrients are low

A team of scientists at the Salk Institute for Biological Studies think they know how many-if not most-living organisms answer this question. They recently showed that when food supplies dwindle, mammals, fruitflies, or frogs probably activate the same ancient cell signaling pathway in order to conserve energy.

Regulating hematopoietic stem cell homeostasis and leukemogenesis

In the April 15th issue of G&D, Dr. Richard Flavell (Yale University) and colleagues identify the c-Cbl protein as a critical repressor of hematopoietic stem cell (HSC) self-renewal.

T-cell multiplication unexpectedly delayed after infection

In a surprising outcome that overturns the conventional wisdom on the body's immune response to infection, scientists at The Scripps Research Institute have shown that T cells do not begin proliferation until up to three days after infection.

Disappointing resuts for pimecrolimus, investigational anti-restenosis drug

A new medication that researchers had hoped would reduce the risk of arterial renarrowing after stenting has turned in a disappointing performance in a multicenter clinical trial, but the multi-reservoir stent that was used to deliver the drug is still considered promising.

Key factor in brain development revealed, offers insight into lissencephaly

In the earliest days of brain development, the brain's first cells - neuroepithelial stem cells - divide continuously, producing a population of cells that eventually evolves into the various cells of the fully formed brain.
