Gene Linked to Development of Skin Cancer in Mice

September 23, 2014 1:52 pm | News | Comments

New research on an enzyme linked to cancer development shows that 37 percent of mice that produce excessive quantities of the enzyme developed skin tumors within four to 12 months of birth, and many of these growths progressed to highly invasive squamous cell carcinoma, a common form of skin cancer.

Airway Muscle-on-a-chip Mimics Asthma

September 23, 2014 1:46 pm | News | Comments

Hope for healthier airways may be on the horizon thanks to a human airway muscle-on-a-chip that could be used to test new drugs because it accurately mimics the way smooth muscle contracts in the human airway, under normal circumstances and when exposed to asthma triggers.
