(A) Effects of GT (Left) or Bcl-2
(Right) on ROS accumulation post-KA. Values are
expressed as percentage above that in mock-infected control cultures
without KA. In control vector-treated wells, KA significantly increased
ROS accumulation (P < 0.05 and 0.01 in GT and
Bcl-2 studies, respectively, post hoc test after two-way ANOVA). In
GT-infected wells, KA did not significantly increase accumulation, and
in either condition (±KA), there was significantly less accumulation
than in cognate control wells (P < 0.01 for both).
In contrast, KA significantly increased accumulation in Bcl-2-treated
wells (P < 0.05), and values did not differ
significantly from the cognate control wells. (B)
Effects of GT or Bcl-2 on metabolism in primary hippocampal cultures
under hypoglycemic conditions as assessed by proton efflux rates,
measured by microphysiometry. vIE1GT (Left) attenuated
the drop of metabolism posthypoglycemia (***,
P < 0.001 by post hoc test after two-way ANOVA,
comparing experimental vector versus control vector at the same time
point), whereas vα22βgalα4bcl-2 (Right) had no
effect. Data on the left previously published (7), making use of a
related HSV vector expressing either GT (vIE1GT) or β-Gal as a
reporter gene (vIE1βGal).
