Figure 7. Age-related changes in Axin2 mRNA levels in hippocampus of 4-, 12- and 24-month-old rats. Levels of mRNA encoding Axin2, measured by quantitative RT-PCR in samples from hippocampus. Results are expressed as percentage of 4-month-old group ± S.E.M., n = 5 for each experimental group. ANOVA followed by Newman-Keuls. (a) p<0.05 vs. 4-month-old basal sample, (b) p<0.05 vs. 12-month-old basal sample.
