Top of pageAbstractDegeneration of retinal ganglion cells (RGCs) an important cause of visual impairment is often modeled by optic nerve transection, which leads to apoptotic death of these central nervous system neurons. With this model, we show that specific voltagegated K+ channels (Kv1 family) contribute to the degeneration of rat RGCs and expression of apoptosisrelated molecules in vivo. Retinal expression of Kv1.1, Kv1.2, Kv1.3 and Kv1.5 was examined by quantitative realtime reverse transcriptasePCR and immunohistochemistry.Maybe it was his brute strength and ability to take abuse that enabled him to work as pit trader on the Chicago Board of Options Exchange for 22 years, where he was known by his floor call letters of He formed Mercury Trading in 1989, built it into a substantial business, and then sold it to the mega hedge fund, Citadel, in 2004.Jon developed his patented algorithms for Heat Seeker with his brother Pete, another former NFL player (Tampa Bay Buccaneers and
