Figure 5. Fibroblasts from longer-lived species of primates have increased mRNA expression of β-2 microglobulin, TAP1, and TAP2 compared with that of shorter-lived species.

(A) Scatter plot of relative TAP1 mRNA levels. (B) Scatter plot of relative TAP2 mRNA levels. (C) Scatter plot of relative β-2 microglobulin mRNA levels. Statistical significance was established using simple linear regression analysis.
