Novel combination of drugs may overcome drug-resistant cancer cells

Cancer cells can adapt and develop resistance to chemotherapy drugs, making it difficult to eradicate tumors. A new study led by investigators from Brigham and Women’s Hospital suggests that a combination of three drugs, including a new class of glucose-6-phosphate dehydrogenase inhibitors, could overcome cross-therapy resistance. The results of the study are published today in […]

Gut throws cells overboard when chemical insults build up

A team of Duke researchers has discovered that cells lining the gut of zebrafish—and probably humans too—have a remarkable defense mechanism when faced with certain kinds of toxins: they hit the eject button. “The gut has the challenging job of handling all the chemicals that we consume or produce, and some of those chemicals can […]

Study finds electronic cigarettes damage brain stem cells

A research team at the University of California, Riverside, has found that electronic cigarettes, often targeted to youth and pregnant women, produce a stress response in neural stem cells, which are critical cells in the brain. Present throughout life, stem cells become specialized cells with more specific functions, such as brain cells, blood cells, or […]

Going the distance: Brain cells for 3-D vision discovered

In stunning images captured under the microscope for the first time, the neurons were found in praying mantises. The work is published in Nature Communications today. In a specially-designed insect cinema, the mantises were fitted with 3-D glasses and shown 3-D movies of simulated bugs while their brain activity was monitored. When the image of […]

Alternative molecular mechanisms observed in cancer cells

Current anti-cancer drugs can be quite effective but too often, tumors are not fought off completely and end up returning. A recent study published in The FASEB Journal provides the first evidence that some cancer cells evade therapy by switching over to alternative molecular mechanisms that are not affected by existing anti-cancer treatments. A research […]
