Experimental details: Figure 7. Studies of GPER expression in hippocampal and cortical cultures and tissues. GPER expression and localization in cultured hippocampal and cortical neurons 72 HIC were measured using immunofluorescent and confocal microscopy techniques. A , Representative fluorescence images showing the localization of GPER (red) in cell bodies (arrowheads) and neurites (arrows). Cell nuclei are labeled with DAPI (blue) and neurites are labeled with MAP2 (green). B , RT-qPCR measurement of the relative GPER mRNA level in samples derived from hippocampal and cortical culture at 72 HIC shows a significantly (unpaired Student's t test, p < 0.01, n = 5 replicates) higher GPER mRNA level in cortical than hippocampal cultures. C , Western blot measurements of GPER protein expression in ex vivo hippocampal and cortical tissues from individual E18 rat brains ( n = 10) reveals two protein species with mass sizes of ~50 and 42 kDa ( i ). Statistical analysis shows that expression of GPER ~50 kDa is significantly higher in cortical than in hippocampal tissues ( ii ), while GPER ~42 kDa is slightly, but not significantly, higher in cortical than in hippocampal tissues ( iii ). Unpaired Student's t test; ** p < 0.01. The specificity of the GPER antibody used for this study was validated by immunocytochemistry and Western blotting. The validation results are shown in Extended Data Figure 7-1 .

Experimental details: Figure 7. Central GPER is critical in regulating locomotor activity in female mice without the Magel2 gene in ARC POMC neurons innervating the MeA. (A) Images of confocal fluorescence microscopy showing expression of GPER in the VMH (middle) and MeA (right) in female mice. Scale bar: 100 mum. (B, C) Summary plots showing VO 2 and respiratory exchange ratio between the experimental groups with G-15 infusion. At 10 wk of viral injection, the GPER antagonist G15 (5 mug/day []) was infused into the LV via osmotic pumps at a rate of 0.25 mul/hour. There were no significant differences in VO 2 and respiratory exchange ratio between the experimental groups. (D, E) Pooled data showing total and ambulatory activity between the experimental groups with G-15 infusion. An increase in locomotor activity was not observed in mice without the Magel2 gene in ARC POMC neurons innervating the MeA following treatment with G-15 infusion. (F, G, H) Summary plot showing TEE between the experimental groups. Regression plot showing TEE versus body weight (H).

Experimental details: Figure 1 Effect of E2 on a 3D model of the milk duct using MCF-10A cells. ( a ) Representative confocal images of MCF-10A cells in a 3D culture through the middle acini, which were treated with E2 (32 nM, left two panels) or control (0 nM, right panel) for 7 days. The basement membrane was examined via immunofluorescence staining using laminin V antibody (red); cell junctions were evaluated using pan-cadherin antibody (green). The reconstructed images of the acini structures by confocal microscopy are shown at the bottom with Hoechst (blue) and laminin V (red) staining. Arrows indicate the collapsed portion of the basement membrane. Scale bars = 5 mum. ( b ) The basement membrane was stained using anti-laminin V antibody, and the percentage of acini with disrupted basement membranes was calculated. Three independent experiments (32 nM E2; 54.5% (n = 55), 50% (n = 48), 43.8% (n = 57), 0 nM E2; 23.1% (n = 52), 22.2% (n = 54), 10% (n = 50)) were performed. Bars represent +/-SD. DATA were analyzed using a Mann-Whitney U test. *p values less than 0.05 were considered statistically significant. ( c ) Representative SEM images of MCF-10A cells in a 3D culture treated with 32 nM E2 for 72 h. SEM images are shown in Matrigel matrix (blue) and basement membrane (pink). ( d ) Western blotting of GPER-expressing cell lysates (MCF-7, U2OS, MCF-10A, T47D, and MDA-MB-231) (left). MCF-7 and MCF-10A cell lysates were further probed for ERalpha expression.
