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.

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.
