Study shows premature birth interrupts vital brain development processes leading to reduced cognitive abilities
Researchers from King's College London have for the first time used a novel form of MRI to identify crucial developmental processes in the brain that are vulnerable to the effects of premature birth. This new study, published ...

Herpes infections: Natural Killer cells activate hematopoiesis
Infections can trigger hematopoiesis at sites outside the bone marrow – in the liver, the spleen or the skin. LMU researchers now show that a specific type of immune cell facilitates such "extra medullary" ...

Study IDs key protein for cell death, offers way to kill cancer cells by forcing them into programmed-death pathway
When cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ...

Study finds four new genetic risk factors for testicular cancer
A new study looking at the genomes of more than 13,000 men identified four new genetic variants associated with an increased risk of testicular cancer, the most commonly diagnosed type in young men today. The findings from ...

Making cancer less cancerous: Blocking a single gene renders tumors less aggressive
Researchers at Johns Hopkins have identified a gene that, when repressed in tumor cells, puts a halt to cell growth and a range of processes needed for tumors to enlarge and spread to distant sites. The researchers hope that ...

Decoded: Molecular messages that tell prostate and breast cancers to spread
Cancer cells are wily, well-traveled adversaries, constantly side-stepping treatments to stop their spread. But for the first time, scientists at the University of Michigan have decoded the molecular chatter that ramps certain ...

Study uncovers molecular role of gene linked to blood vessel formation
University of North Carolina researchers have discovered that disrupting a gene that acts as a regulatory switch to turn on other genes can keep blood vessels from forming and developing properly.

Reassigning cells to fight infection
Just as a uniform helps distinguish a soldier from a police officer, scientists use proteins that immune cells wear on their surfaces to determine their job in the body. T cells, for example, that display ...
