Slot-blot analysis of 3-NT levels in rat brain homogenates. Slot blot analyses were performed using brain samples of rats fed a control, low VitD or high VitD diet from middle-age to old-age (n=9). Data show a significant increase in 3-NT levels in rat brains between control and low VitD diet (*p<0.01). No difference was observed in high VitD diet when compared to control. High VitD diet decreases 3-NT levels when compared to low VitD diet (**p<0.05).
