mRNA expression level of SUMO and SUMO-related proteins in hippocampal tissues. Analyses of SUMO-1 (A), SUMO-2 (B), SUMO-3 (C), SENP1 (D), Ubc9 (E) mRNA expression in brain hippocampus of Tg2576 and WT mice at the age of 1.5 and 6 months. The mRNA expression levels, determined by real-time polymerase chain reaction (RT-PCR), were expressed in relation to glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and presented as fold increase relative to WT animals. Data represent mean ± s.e.m. of 4 animals. (t-test) *p < 0.05 Tg2576 vs. WT.
