Figure Lengend Snippet: (A) Representative images showing GFP and c-Fos (arrows) expression patterns in the PVT, a downstream target of the VMH, in AAV-DIO-EYFP, AAV-DIO-NaChBac+sgRNA, AAV-DIO-NaChBac+sgVglut2 injection SF1-Cre::ERa-Cre mice. scale bar=250 um. (B) Representative images showing GFP (green) and c-Fos (red, arrows) expression patterns in the PVT, a downstream target of the VMH, in SF1-Cre::ERa-Cre::BDNFflox/++EYFP, SF1-Cre::ERa-Cre::BDNFflox/++NaChBac, SF1-Cre::ERa-Cre::BDNFflox/flox+NaChBac mice. scale bar=250 um. (C) Number of c-Fos positive cells in the PVT region related to panel A. n=4-5 per group; one-way ANOVA; ***P<0.001 versus EYFP; ###P<0.001 versus NaChBac+sgRNA. (D) number of c-Fos positive cells in the PVT region related to panel A. n=4-5 per group; one-way ANOVA; ***P<0.001 versus EYFP; ###P<0.001 versus SF1-Cre::ERa-Cre:: BDNFflox/flox+NaChBac. (E) Diagram of viral delivery (AAV-DIO-mCherry, AAV-DIO-BDNF-mCherry+sgRNA, AAV-DIO-BDNF-mCherry+sgVglut2) into the VMH of SF1-Cre::ERa-Cre mice. (F) Body weight trajectories of SF1-Cre::ERa-Cre mice after VH injection of virus. n=4 (EYFP, BDNF+sgVglut2), n=5 (BDNF+sgRNA); two-way ANOVA; *P<0.05, **P<0.01, ***P<0.001 versus mCherry; #P<0.05 versus BDNF+sgRNA. (G) Daily food intake. n=4-5 per group, one-way ANOVA, **P=0.006 versus mCherry; #P=0.043 versus BDNF+sgRNA. (H) Total number of jumps during a 10-min test. n=4-5 per group; one-way ANOVA; ***P<0.01 versus mCherry; ###P<0.001 versus BDNF+sgRNA. (I, J) time spent in the light room in light-dark test (I), social time with stranger in three-chamber test (J). n=4-5 per group; one-way ANOVA; *P<0.05, ***P<0.01 versus mCherry; #P<0.05 versus BDNF+sgRNA. (K) Representative images showing mCherry (green) and c-Fos (magenta, arrows) expression patterns in the PVT, a downstream of VMH, in mCherry, BDNF+sgRNA, BDNF+sgVglut2 injection SF1-Cre::ERa-Cre mice. scale bar=250 um. (L) number of c-Fos positive cells in PVT region related to panel K. n=4-5 per group; one-way ANOVA; ***P<0.001 versus mCherry; ###P<0.001 versus BDNF+sgRNA.
Article Snippet: The following primary antibodies were used: rabbit anti-cFos (1:1000, #2250, Cell Signaling Technology), rabbit anti-BDNF(1:200, ANT-010, Alomone Labs), goat anti-GFP (1:1000, 51370, ROCKLAND), rabbit anti-ER alpha (1:500, NBP1-84827), chicken anti-mCherry (1:500, MCHERRY-0020, aves labs).The next day, sections were rinsed three times in PBS with 0.1% Triton X-100 and incubated with secondary antibodies prepared in the same diluent (secondary antibody, 5% normal donkey serum, 0.1% Triton X-100 in PBS).
