Figure 6. Expression of stress-related genes by quantitative real-time PCR (qRT-PCR). There are three corrections. A: Vegf, B: αA-crystallin, C: αB-crystallin, and D: Gfap in 3-, 6-, 12-, and 15-month-old WNIN/GROb. Data represent fold change (mean ± SD) over respective age-matched lean rats (n = 3; “*” p<0.05). The expression value of each bar was compared to its respective age-matched lean rat which is taken as 1 (or 100%) for calculating the fold change. “*” significantly different from the respective age-matched lean rats at p≤0.05.
