I know you weren't!
The thing is, researchers are checking to see if folic acid helps somehow - but no one really expects a single-molecule therapy to help at this stage of our understanding. There *is* something wonky about the way that pathway is behaving in our pregnancies, but epigenetics is complex stuff and it will take more poking at the problem to figure out how to address it theraputically.
I'm always so excited to see all the new papers on preeclampsia. We'll get some traction eventually. They just found something really interesting for another complex disease pathway: http://www.sciguru.com/newsitem/14328/s ... m-epilepsy
Eventually, we'll get a hit like that (and lots of people are working on it.)
