RNA editing process plays essential role in embryo development
...the ADAR1 gene is knocked out, the reduced or lost capacity to edit messenger RNA causes this defect in red blood cell production," Nishikura says. "Our next goal is to identify the target gene or genes that must be edited by the ADAR1 enzyme in order for red blood cell production to occur, as well as other t...Screensavers of the world, unite!

Even though aspirin's pain-killing capacity was well known to Hippocrates in the fifth century B.C., exactly what it does remains somewhat of a mystery. Now, Johns Hopkins researchers have shown that aspirin inhibits interleukin-4, a protein involved in allergic reactions and inflammation. ...Social scientists and biologists collaborate to address human dimensions of biodiversity
