FIGURE 8.
Knockdown of Netrin-1 (NTN-1) in hippocampal CA1 regions reversed the increase of anxiety-like behaviors caused by MS. (A) In OFT, compared with rats injected Lenti-Scramble (MS + Scramble), rats expressing Lenti-shNTN-1 (MS + shNTN-1) showed longer distance traveled, (B) more entries into the center zone, and (C) more rearing. (D) In the EPM test, the percentage of numbers of entries into OA and (E) the percentage of time spent in OA in the MS + shNTN-1 group were significantly increased, and (F) the anxiety index was reduced significantly. (G) Representative animal track in the OFT and (H) EPM. MS + Scramble: n = 12. MS + shNTN1: n = 12. All data were given as mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001, two-tailed unpaired Student’s t-test.
