Resistance to lung cancer targeted therapy can be reversed, study suggests
Up to 40 percent of lung cancer patients do not respond to a targeted therapy designed to block tumor growth -- a puzzling clinical setback that researchers have long tried to solve. Now, scientists have discovered why that intrinsic resistance occurs -- and they pinpoint a drug they say could potentially reverse it.

Longer telomeres linked to risk of brain cancer
New genomic research led by UC San Francisco scientists reveals that two common gene variants that lead to longer telomeres, the caps on chromosome ends thought by many scientists to confer health by protecting cells from aging, also significantly increase the risk of developing the deadly brain cancers known as gliomas.

Targeting tumors using silver nanoparticles
Scientists at UC Santa Barbara have designed a nanoparticle that has a couple of unique -- and important -- properties. Spherical in shape and silver in composition, it is encased in a shell coated with a peptide that enables it to target tumor cells. What's more, the shell is etchable so those nanoparticles that don't hit their target can be broken down and eliminated. The research findings appear today in the journal Nature Materials.

Herpesviruses undercover
Pathogens entering our body only remain unnoticed for a short period. Within minutes our immune cells detect the invader and trigger an immune response. However, some viruses have developed strategies to avoid detection and elimination by our immune system. Researchers from the Helmholtz Centre for Infection Research in Braunschweig have now been able to show how the herpesviruses achieve this.

Biomarkers accurately distinguish mesothelioma from non-cancerous tissue
Scientists have identified four biomarkers that may help resolve the difficult differential diagnosis between malignant pleural mesothelioma (MPM) and non-cancerous pleural tissue with reactive mesothelial proliferations. This is a frequent differential diagnostic problem in pleural biopsy samples taken from patients with clinical suspicion of MPM. The ability to make more accurate diagnoses earlier may facilitate improved patient outcomes. This new study appears in the Journal of Molecular Diagnostics.

Race could be a factor in head and neck cancer survival rates, MU researchers find
The national survival rates for African-Americans diagnosed with head and neck cancer have not improved in the last 40 years despite advances in the treatment and management of the disease, University of Missouri School of Medicine researchers have found. The researchers suggest that inherent genetic factors in African-Americans may make some tumors resistant to treatments. However, more research needs to be done on the subject of survival disparity in patients with head and neck cancer.

Discovered a new way to control genetic material altered in cancer
When we speak of genetic material, we are usually referring to the DNA that we inherit from our parents. This DNA is the factory where is built a similar molecule called RNA which produces our proteins, such as hemoglobin or insulin, allowing the lives of our cells. But there is a special group called non-coding RNA that has a more enigmatic function.

Our own treacherous immune genes can cause cancer after viral infection
Mutations that cause cancer following HPV, human papillomavirus, infection are caused by a family of genes that normally protect against viral infections, finds new UCL research. This raises the possibility of developing drugs that block the activity of these genes to prevent HPV-associated cancers from developing and reduce the ability of existing cancers to evolve resistance to treatments.

Seemingly invincible cancers stem cells reveal a weakness
Metastatic cancer cells, which can migrate from primary tumors to seed new malignancies, have thus far been resistant to the current arsenal of anticancer drugs. Now, however, researchers at Whitehead Institute have identified a critical weakness that actually exploits one of these cells' apparent strengths -- their ability to move and invade tissues. Their research could inform novel approaches to screening tumors for personalized therapy or to drugs that specifically target these cells.
