Expression of tRF5-ProAGG putative targets in the hippocampus. (A-H) qRT-PCR was performed to detect SV2B (A), CDH8 (B), NEFL (C), CALN1 (D), C1ORF216 (E), KALRN (F), CLVS2 (G), and SYT13 (H) in hippocampus from CN and AD patients. (I) The graphic demonstrates Spearman’s rank correlation between tRF5-ProAGG expression and SV2B. (J) Patient information for samples used in A-I. *p < 0.05. Unpaired two-tailed Mann-Whitney U tests were used, and data are shown as mean ±SE.
