Behavioral characterization of TK-GFP and wild-type adult females
Behavior | WT, mean ± SEM (n = 10) | TK-GFP, mean ± SEM (n = 8) | p value |
---|---|---|---|
Time in the center (s), open field test | 11.2 ± 1.1 | 9.0 ± 1.3 | 0.20 |
Distance traveled (cm), open field test | 2030 ± 88 | 1978 ± 116 | 0.72 |
Time in the illuminated area (s), dark–light test | 172 ± 38 | 176 ± 42 | 0.95 |
Number of transitions, dark–light test | 37.2 ± 7.9 | 38.7 ± 8.0 | 0.90 |
Preference index to novel object (%), object-recognition task | 59.1 ± 1.9 | 62.9 ± 3.2 | 0.30 |
Time exploring object mouse (s), social affiliation test | 77.9 ± 5.1 | 84.2 ± 6.0 | 0.43 |
Number of escapes, social affiliation test | 0.8 ± 0.25 | 1.37 ± 0.42 | 0.23 |
Wild-type (n = 10) and TK-GFP (n = 8) littermates (n = 10) were singly housed from PND 30–65 and tested in the following behaviors from PND 66–72: open-field, dark–light, object-recognition, and social affiliation test. These mice did not undergo intracerebroventricular surgery or exposure to GCV. However, exposure to intracerebroventricularly delivered PBS during this same period did not modify social behavior in TK-GFP mice (Fig. 7A,B), indicating that exposure to intracerebroventricularly delivered GCV is necessary to induce social abnormalities in TK-GFP female mice.
