Fig. 7. Levels of total polyadenylation in all size classes combined are lower under all experimental treatments relative to control conditions (normoxia, pH 7.8). The amounts of fluorescence in poly(A)⁺ tails (PAT) from the gels in Fig. 5 were normalized and 6 h time points compared. Asterisks indicate significant differences from controls for the mean of N=3 separate experiments.
