Creatine and α-ketobutyrate, both at a 20 mM concentration, also exerted a remarkable protection against AMPA-induced excitotoxicity, which was very similar to that of 100 mM lactate and of 20 mM pyruvate, in terms of motor behavior, rotarod performance and MN death.
It is likely that TRPM5 is not the sole signaling ion channel mediating the bitter signal transduction in the SCCs of the VNO, since access of denatonium at 10 mM concentration was also reduced in the knockout animals.
AMPK assays in solution were performed as previously described (Hardie et al., 2000), except that in some assays (specified in the figure legends) the concentration of ATP was increased from 0.2 to 1 or 5 mM, with MgCl2 concentrations also increased (5, 5.8, or 9.8 mM, respectively) to maintain a constant excess of [Mg2+] over [ATP].
As shown in Figure 2, growth on low (1.4 mM) concentrations of mannose also leads to a significant reduction in 20 1 breakdown.
The 25 mM glucose concentration also decreased intracellular and released DPP4 levels in mature adipocytes obtained from normal mice following 24-hour incubation.
Injection with 0.1 or 0.01 mM concentrations of the cocktail also affected the shape of the acquisition curve, but to a lesser degree over later trials.
Stable, high PL intensities and a fast rate of intercalation were observed for 3 mM concentrations, but acceptable results were also obtained for 5 8 mM concentrations.
Other NO donors, SIN-1 and SNAP, also induced significant chondrocyte death at 2 mM concentrations.
Perfusion of pyruvate, βHB, GEE or ascorbate alone at 20 mM concentration (n = 3 per group) was also innocuous (not shown).
The library was also tested against Mycobacterium tuberculosis galactosyltransferase GlfT2, and one compound showed effective inhibition at 1 mM concentration.
