Post-Operative Radiation Therapy Improves Overall Survival for Patients with Resected Non-Small Cell Lung Cancer

Patients who received post-operative radiation therapy (PORT), radiation therapy after surgery, lived an average of four months longer when compared to the patients who had the same disease site, tumor histology and treatment criteria and who did not receive PORT, according to research presented today at the 2014 Chicago Multidisciplinary Symposium in Thoracic Oncology.

Blocking a Fork in the Road to DNA Replication

A team of Whitehead Institute scientists has discovered the surprising manner in which an enigmatic protein known as SUUR acts to control gene copy number during DNA replication. It’s a finding that could shed new light on the formation of fragile genomic regions associated with chromosomal abnormalities.

Why Scratching Makes You Itch More

Turns out your mom was right: scratching an itch only makes it worse. New research from scientists at the Center for the Study of Itch at Washington University School of Medicine in St. Louis reveals that scratching causes the brain to release serotonin, which intensifies the itch sensation.

A University of Utah-led study reports that cancers select against a protein complex called the mitochondrial pyruvate carrier (MPC), and re-introduction of MPC in colon cancer cells impairs several properties of cancer, including growth. The research, which appears online on Oct. 30 in Molecular Cell, implicates changes in a key step in metabolism – the way cellular fuel is utilized – as an important driver of colon cancer that is also likely to be important in many other cancer settings.

Molecular Tumor Markers Could Reveal New Therapeutic Targets for Lung Cancer Treatment

Analysis of 607 small cell lung cancer (SCLC) lung tumors and neuroendocrine tumors (NET) identified common molecular markers among both groups that could reveal new therapeutic targets for patients with similar types of lung cancer, according to research presented today at the 2014 Chicago Multidisciplinary Symposium in Thoracic Oncology.
