How gene linked to cancer moves cells
CORNELL (US) — Mutations to the p53 gene have been linked to half of all cancers, and now researchers have identified how the gene controls cell movement and invasion into other areas of the body. (more…)

Stretch a gene to silence it
U. ARIZONA (US) — Cells may control genes by simply stretching them, a discovery that could pave the way for applications that require precise control over gene expression, such as the “lab on a chip.” (more…)

What makes genes stop and go?
MICHIGAN STATE (US) — Knowing how certain proteins are supposed to slow genes during development could explain how some diseases like cancer occur when those genes are unable to shift gears properly and can’t stop. (more…)

Marsupial embryos pump up early on
DUKE (US) — Not only is the marsupial unusual in the way the embryo grows outside the mother’s womb, it also develops in a different order than virtually every other vertebrate animal. (more…)

Roots ride wave of gene expression
DUKE (US)—A surprising parallel exists between the development of an animal’s spinal column and a plant’s root system: both appear to be controlled by a “molecular clock” that governs a regular spatial pattern of development. (more…)

Diet linked to changes in breast cancer DNA
BROWN (US)—A new study suggests that epigenetic profiles of breast cancer tumors have a direct association with diet, alcohol, and tumor size. The finding could offer a new way to predict the severity of the disease. (more…)

What separates the cells from the T cells?
CALTECH (US)—When does a cell decide its particular identity? In the case of T cells—immune system cells that help destroy invading pathogens—the answer is when the cells begin expressing a particular gene, according to a new study. (more…)

Genes reveal differences in breast vs. bottle
U. ILLINOIS (US)—While breast-fed and formula-fed babies both gain weight and seem to develop similarly, genetic tracking of an infant’s intestines offers new proof that the difference between the two are very real. (more…)

Signs of prenatal smoking in DNA
“Maternal smoking during pregnancy is not only detrimental to the health of the mom and the newborn child, but research such as this suggests that it may impact the child into adulthood and possibly even future generations as well,” says Linda Birnbaum, director of the National Institute of Environmental Health Sciences.
