Technique for genetically modifying blood stem cells brings cure for blood diseases closer

... than 15 percent. "The enhancement in expression of the gamma-globin gene that was key to the success of this new vector was due to the additional controlling elements we added," said Hideki Hanawa, M.D., Ph.D. Hanawa is the first author of the Blood article and a former postdoctoral ...

Genetic discovery paves way to decode sense of smell in mammals

...her protein known to bind olfactory receptors. The enhancement of these protein levels made it possible for the researchers to induce the newly created cells to express odorant receptors at their surfaces. The team then tested the receptors' response to various chemicals, including the fishy-smelling aliphatic a...

Global warming good news for coral reefs: research

... coral reef calcification is most likely due to an enhancement in coral metabolism and/or increases in photosynthetic rates of red algae, according to the scientists. They used projections of ocean warming and CO2 concentration from a CSIRO climate model that accounts for atmosphere-ice and ocean carbon cycles. ...

What has long remained a mystery, however, is the question of how Notch receptors that have not been activated by a ligand are ...

Mouse brain tumors mimic those in human genetic disorder

...true in humans, this strongly argues that contrast enhancement on MRI alone is not a reliable test of tumor progression," Gutmann says. "If we rely on contrast enhancement in children with NF1 optic pathway gliomas, we may be treating kids who don't need to be treated. Us...

Mitochondrial DNA mutations play significant role in prostate cancer

...important contributory factor in the mitochondrial enhancement of prostate cancer tumor growth. Because the study found that COI mutations were common in the general population (7.8 percent), but very infrequent (<2 percent) in men without prostate cancer, the investigators noted that men harboring these mut...
