Figure Lengend Snippet: (A–F) Immunohistochemistry technique for capturing SNPH intrusion in PC dendrites. Shown is SNPH (green), Syt2 (red), and Calbindin (blue) labeling in 3.5-month-old WT (A, C, and E) and Shi (B, D, and F) mice. Scale bar, 10 μm. (G and H) High magnification of the maximum intensity projection image from the z stack through dendritic regions of WT (G) and Shi (H). (I and J) Orthogonal (slice) view of SNPH punctum (indicated by arrows in panels G and H) in the dendritic region from WT (I) and Shi (J) in x-z and y-z orientations, respectively. (K) Quantification of percentage area occupied by SNPH within the dendritic volume from 3 mice of each group. Data are shown as mean ± SEM. *p < 0.05. (L–N) Capturing SNPH intrusion by pre-tagging dendritic mitochondria in vivo using viral transduction. (L) Technique to selectively transduce PCs with AAV-Mito-mCherry. (M) Demonstration of successful pre-tagging of mitochondria in dendrites of a single PC by Calbindin staining. Scale bar, 10 μm. (N) Demonstration of how pre-tagged dendritic mitochondria in PCs are used to capture SNPH intrusion by 3D rotation. (O and P) Single dendritic tree in WT (O) or Shi (P) pre-tagged with Mito-mCherry (red) and SNPH intrusion (green) captured by co-rotation with Mito-mCherry. Merged images show the fraction of dendritic mitochondria anchored by intruded SNPH (yellow). (Q and R) Percentage of PCs with SNPH intrusions (Q) and percentage of SNPH bound to mitochondria per dendritic tree (R) from WT (n = 73) and Shi (n = 106) PCs. Data are shown as mean ± SEM. ***p < 0.005.

Figure Lengend Snippet: (A and B) Representative images of lentivirally transduced GFP-SNPH (1–469) (A) and GFP-SNPH (B) in PCs of SNPH-KO mice injected with saline (no harmaline, vehicle only). (C-H) Effect of harmaline on GFP-SNPH (1–469)-transduced (C) and GFP-SNPH-transduced (F) PC dendrites. Degenerating dendrites in GFP-SNPH-transduced PCs can be seen in (F). Also shown is Calbindin labeling of GFP SNPH (1–469) (D) and GFP-SNPH (G) from (C) and (F). Merged images of GFP SNPH (1–469) and GFP-SNPH with Calbindin are shown in (E) and (H), respectively. (I–K) Representative image of a harmaline-induced degenerating PC (white arrow in I) transduced with GFP-SNPH. Calbindin staining from the same section is shown in (J), whereas a merged image is shown in (K). Scale bars, 20 μm. (L) Quantification of dendritic shrinkage in GFP-SNPH (1–469)- and GFP-SNPH-transduced PCs in the absence (n = 3 mice, vehicle only) or presence of harmaline (n = 5 mice). Data are shown as mean ± SEM. ***p < 0.001.

Article Title: Sex-Dependent Regulation of Aromatase-Mediated Synaptic Plasticity in the Basolateral Amygdala

doi: 10.1523/JNEUROSCI.1532-16.2016

Figure Lengend Snippet: AROM expression in major subregions of rodent amygdala. A, Coronal section through anterior amygdala of an young adult mouse, immunostained for AROM using rabbit polyclonal antibodies (Yague et al., 2006). Substantial AROM expression is detectable in the MeA and CeA, in the BL and La nucleus of the BLA, and in the adjacent piriform cortex (Pir). Virtually, no AROM immunoreactivity is seen in the BM of BLA. Low levels of expression were found in the cortical amygdala (CoA). Scale bar, 250 μm. B, Western blots showing AROM protein expression in amygdala subregions CeA, BLA, and MeA of juvenile male and female rats using monoclonal antibodies against AROM (Acris). Tissue from hippocampus (Hip), cerebellum (Cer), and somatosensory cortex (Cor) was blotted for comparison. The strongest signal is found in the MeA. AROM expression levels in the CeA and BLA are comparable to levels in the hippocampus, neocortex, and cerebellum (note: a representative band for the female CeA was inserted from a different gel). C, Quantitative analysis of Western blot data, comparing AROM expression in BLA of age-matched (P20–P24) juvenile male and female rats. No difference between the sexes was evident (rel. expression of AROM: 0.46 ± 0.06 in females; 0.48 ± 0.09 in males; p = 0.88; n = 8 of each sex).
