Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...n it is growing inside the red cell. These changes affect how drugs like chloroquine enter the parasite, and how efficiently they bind to pre-crystalline heme. If these drugs can't enter blood cells as efficiently, and if the efficiency of heme binding is pushed in the wrong direction, they can't prevent he...

Stroke study sheds light on left-right brain divide

U-M researchers discover gene switched off in cancer can be turned on

...ne deacetylase inhibitors, or HDAC inhibitors, can affect gene expression, the researchers applied these drugs to the cells and found the BRM expression could be restored – like flipping the switch back on. While the existing HDAC inhibitors did return BRM expression, the effect was short-lived. Once the...
