Protein that stimulates blood vessel growth worsens ovarian cancer

A protein that stimulates blood vessel growth worsens ovarian cancer, but its production can be stifled by a tiny bit of RNA wrapped in a fatty nanoparticle, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Journal of the National Cancer Institute.

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.

Researchers explain why Avastin can cause potentially fatal brain inflammation

New research by scientists at Schepens Eye Research Institute may help explain why the anti-cancer drug Avastin, which targets a growth factor responsible for creation of new blood vessels, causes potentially fatal brain inflammation in certain patients.
