Genetic variations raise lung cancer risk for smokers and ex-smokers

Two common inherited genetic variations are associated with increased risk of lung cancer for smokers and former smokers, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports April 2 in the online edition of Nature Genetics.

Discovery of role of rare gene mutations in schizophrenia

Using an important new method that can be applied in the study of other psychiatric illnesses, scientists at Cold Spring Harbor Laboratory (CSHL) in collaboration with colleagues at the University of Washington (UW) and the National Institute of Mental Health (NIMH), have identified multiple, individually rare gene mutations in people with schizophrenia that may help explain how that devastating illness is caused.

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.

Cell therapy for rejuvenating aged brain by injection of human umbilical cord blood

When human umbilical cord blood cells (UCBC) were injected into aged laboratory animals, researchers at the University of South Florida (USF) found improvements in the microenvironment of the hippocampus region of the animals' brains and a subsequent rejuvenation of neural stem/progenitor cells.

Molecular alliance that sustains embryonic stem cell state

One of the four ingredients in the genetic recipe that scientists in Japan and the U.S. followed last year to persuade human skin cells to revert to an embryonic stem cell state, is dispensable in ES cells, thanks to the presence of a molecular alliance between a specific group of key proteins known as transcription factors, a research team led by the Genome Institute of Singapore (GIS) under the Agency for Science, Technology and Research (A*STAR) reports in the current issue of Nature Cell Biology.

Inverted DNA turns quiet developmental gene into a potent driver of t-cell lymphoma

A gene crucial for embryonic development can quickly become a potent cancer promoter in adult mice after a genetic misalignment, according to researchers from Fox Chase Cancer Center, causing white blood cells to become cancerous spontaneously.

Artificial 'cells' that boost the immune response to cancer

Using artificial cell-like particles, Yale biomedical engineers have devised a rapid and efficient way to produce a 45-fold enhancement of T cell activation and expansion, an immune response important for a patient's ability to fight cancer and infectious diseases, according to an advance on line report in Molecular Therapy.

Small protein discovered that specifically recognizes tumors responding to chemotherapy

A technique that specifically "tags" tumors responding to chemotherapy may offer a new strategy for determining a cancer treatment's effectiveness within days of starting treatment, according to a new study by Vanderbilt-Ingram Cancer Center investigators.

Notch protein plays a critical role in bone formation

Notch, a protein known to govern the determination of cell differentiation into different kinds of tissues in embryos, plays a critical role in bone formation and strength later in life, said researchers from Baylor College of Medicine in Houston in a report that appears online today in the journal Nature Medicine.

Newly discovered ERK pathway proteins related to CagA induced disease

Cytotoxin-associated gene A protein (CagA) from type I H.pylori has been proved by epidemiological and experimental studies to be closely associated with the H.pylori induced gastric diseases, especially gastric cancer.

Study identifies another strategy for normalizing tumor blood supply

Manipulating levels of nitric oxide (NO), a gas involved in many biological processes, may improve the disorganized network of blood vessels supplying tumors, potentially improving the effectiveness of radiation and chemotherapy.

Oncoproteins double-team and destroy vital tumor-suppressor

Two previously unconnected cancer-promoting proteins team up to ambush a critical tumor suppressor by evicting it from the cell's nucleus and then marking it for death by a protein-shredding mechanism, a team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Feb. 10 issue of Nature Cell Biology.
