Wnt, aging, and the fountain of youth
You're not getting any older--just your blood is. LOL The story is actually a lot more complicated than that but there's two articles in the August 10 issue of Science that indicate that the environment (ie blood) our cells are in is a lot more important vis a vis aging than the cells themselves. Further, that it's a protein referred to as wnt that is the big player in this. Wnt has long been known to be a very important regulatory protein. The name is derived from "wingless" and "integrative" and dates back to early genetic work on fruit flies on the wingless side and vertebrate studies on the integrative. As you can see to the left, the wnt pathway is complex. My research has dipped into the APC area quite a few times and one of the genes I'm working on right now is for a frizzled protein (the FRZ in the diagram) but I've never worked with wnt directly.
