Research identifies a way to make cancer cells more responsive to chemotherapy
Breast cancer characterized as "triple negative" carries a poor prognosis, with limited treatment options. In some cases, chemotherapy doesn't kill the cancer cells the way it's supposed to. New research explains why some cancer cells don't respond to chemotherapy, and identifies a mechanism to rectify that. ...

When oxygen is short, EGFR prevents maturation of cancer-fighting miRNAs
Even while being dragged to its destruction inside a cell, a cancer-promoting growth factor receptor fires away, sending signals that thwart the development of tumor-suppressing microRNAs before it's dissolved, researchers have reported. ...

Scientists discover how rapamycin slows cell growth
University of Montreal researchers have discovered a novel molecular mechanism that can potentially slow the progression of some cancers and other diseases of abnormal growth. In the May 23 edition of the prestigious journal Cell, scientists have explained how they found that the anti-cancer and anti-proliferative drug rapamycin slows down or prevents cells from dividing. ...

Cradle turns smartphone into handheld biosensor
Researchers and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones. Researchers have developed a cradle and app for the iPhone that uses the phone's built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules. Although the cradle holds only about $200 of optical components, it performs as accurately as a large $50,000 spectrophotometer in the laboratory. ...

Ferrets, pigs susceptible to H7N9 avian influenza virus
Chinese and US scientists have used a virus isolated from a person who died from H7N9 avian influenza infection to determine whether the virus could infect and be transmitted between ferrets. Ferrets are often used as a mammalian model in influenza research, and efficient transmission of influenza virus between ferrets can provide clues as to how well the same process might occur in people. ...

Biophysicists measure mechanism that determines fate of living cells
For the first time, biophysicists have measured the molecular force required to mechanically transmit function-regulating signals within a cell. A new laboratory method, named the tension gauge tether approach, has made it possible to detect and measure the mechanics of the single-molecule interaction by which human cell receptors are activated. ...

New screening approach uncovers potential alternative drug therapies for neuroblastoma
Nearly two-thirds of patients with high-risk neuroblastoma -- a common tumor that forms in the nerve cells of children -- cannot be cured using tumor-killing cancer drugs. A new study reveals a new genomic approach to screen for compounds that inhibit tumor growth by causing cancer cells to differentiate. Using this screening method, the researchers identified a compound that causes neuroblastoma cells to differentiate, uncovering promising new treatment strategies. ...
