Cell Bio in Everyday Life

February 14, 2007

Nitric oxide is also used by neurons to signal nearby cells. For example, nitric oxide released by the neurons in the penis results in the blood vessel dilation responsible for erection. The drug sildenafil, sold under the trade name Viagra, is an inhibitor of a phosphodiesterase that normally catalyzes the breakdown of cyclic GMP. By maintaining elevated levels of cyclic GMP in erectile tissue, this pathway is stimulated for a longer time period following NO release.

Nice. And you thought I was bad in AP Bio. Just think of what I could have done with this!


In all seriousness, the section I just read for my next lecture of Cell Bio got me thinking that maybe I would like to go into Bio Chem. Or neuroscience. Or nanobioneuroscience. Yeah, that’s what I want!


Now excuse me while I get all the giggles out of my system…
