Researchers have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, called "CAMo," for coherent angular motion, is necessary for the cells to form spheres. Otherwise, cells undergo random motion, ...

Scientists have identified a gene that tells cells to develop multiple cilia, tiny hair-like structures that move fluids through the lungs and brain. The finding may help scientists generate new therapies that use stem cells to replace damaged tissues in the lung and other organs.

A new study has discovered how normal cells in tumors can fuel cancer progression. The study examines what happens when normal cells called fibroblasts in tumors lose an important tumor-suppressor gene. The findings suggest new strategies for controlling tumor growth, they provide insight into the mechanisms that control the co-evolution ...

Scientists investigating the interactions, or binding patterns, of a major tumor-suppressor protein known as p53 with the entire genome in normal human cells have turned up key differences from those observed in cancer cells. The distinct binding patterns reflect differences in the chromatin (the way DNA is packed with proteins), ...

Among patients who experienced an ischemic stroke, systolic blood pressure levels of less than 120 mm Hg, or higher than 140 mm Hg, were associated with an increased risk of subsequent stroke, according to a new study.

Like a bridge that spans a river to connect two major metropolises, the corpus callosum is the main conduit for information flowing between the left and right hemispheres of our brains. Now, neuroscientists have found that people who are born without that link -- a condition called agenesis of the ...

People with prehypertension have a 55 percent higher risk of experiencing a future stroke than people without prehypertension, report researchers in a new meta-analysis of scientific literature.

Brain tumor specimens taken from neurosurgery cases have given scientists a new window on the transformation that occurs as healthy brain cells begin to form tumors.

The first large-scale analysis of life expectancy outcomes in Africa for HIV patients receiving combination antiretroviral therapy (cART) shows that such patients can expect to live a near normal lifespan. The study also shows significant variance between patient subgroups.

Researchers have found that a type of normal stem cell fuels ovarian cancer by encouraging cancer stem cells to grow.

Whether patients with Type 2 diabetes mellitus benefit from attempts to lower their blood glucose levels to near-normal levels through treatment ("intensive blood glucose control") remains an unanswered question. The studies currently available provide indications of a benefit but also of potential harm, researchers say.

A team of researchers — led by Pierre Gressens, at Inserm U676, Paris, France, and Vincent Lelièvre, at CNRS UPR-3212, Strasbourg, France — has identified a signaling pathway key for normal brain development in the mouse. Of paramount importance, the data generated suggest that environmental factors, including maternal ones, can ...
