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.

Smoking's effects on genes may play a role in lung cancer development and survival

Smoking plays a role in lung cancer development, and now scientists have shown that smoking also affects the way genes are expressed, leading to alterations in cell division and regulation of immune response.

Hormone refractory prostate cancers more likely to spread to other organs

Prostate cancers that are resistant to androgen deprivation therapy are more invasive and more likely to spread to other organs than androgen dependent prostate cancers, UCLA cancer researchers have found.

Tumor-killing virus selectively targets diseased brain cells

New findings show that a specialized virus with the ability to reproduce its tumor-killing genes can selectively target tumors in the brains of mice and eliminate them.

Tumor blood vessels can develop from precancerous stem cells

Tumors require a blood supply to grow, but how they acquire their network of blood vessels is poorly understood.

Study finds increase in thyroid diseases risk from radiation exposure at Chernobyl

Persons exposed to radioactive fallout from the Chernobyl accident as children and adolescents have an increased risk of follicular adenoma or benign tumor of the thyroid gland, according to researchers at Columbia University Mailman School of Public Health.

Gene therapy - immune system discovery may lead to effective treatment for glioblastoma multiforme

A new gene therapy approach that attracts and "trains" immune system cells to destroy deadly brain cancer cells also provides long-term immunity, produces no significant adverse effects and -- in the process of destroying the tumor -- promotes the return of normal brain function and behavioral skills, according to a study conducted by researchers at Cedars-Sinai Medical Center's Board of Governors Gene Therapeutics Research Institute.

New key finding in neurodevelopment

A longstanding puzzle in neurodevelopment may have yielded up a key secret. A team led by scientists at Weill Cornell Medical College says they have determined how events at the very tips of the developing neuron's long, skinny axon affect gene transcription back in the cell's distant nucleus.

Tumor-targeting viral therapy slows neuroblastoma, malignant peripheral nerve sheath tumors

Researchers in a multi-institutional study led by Cincinnati Children's Hospital Medical Center slowed the growth of two particularly stubborn solid tumor cancers - neuroblastoma and peripheral nerve sheath tumors - without harming healthy tissues by inserting instructions to inhibit tissue growth into an engineered virus, according to study results published in the February 15 Cancer Research.

Personalized medicine can cut breast cancer risk

The time has come for breast cancer risk assessment, counseling and genetic testing to move from cancer specialists to the realm of primary care, according to a presentation at the AAAS annual meeting, held this year in Boston.

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.

Mesothelin appears to play important role in promoting pancreatic cancer growth - clues to new treatments

New understanding of a protein that spurs the growth of pancreatic cancer could lead to a new vaccine against the deadly disease, said researchers at Baylor College of Medicine in Houston in a report appearing in the current edition of the journal Molecular Cancer Therapeutics.
