Experimental details: Immunofluorescent analysis of Estrogen Receptor alpha using Anti-Estrogen Receptor alpha Monoclonal Antibody (EVG F9) (Product # MA3-310) shows staining in MCF-7 Cells. Estrogen Receptor alpha staining (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with or an antibody recognizing Estrogen Receptor alpha (Product # MA3-310) at a dilution of 1:200 over night at 4°C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product # 35503, Goat Anti-Mouse). Images were taken at 60X magnification.

Experimental details: Immunohistochemistry was performed on cancer biopsies of deparaffinized Human breast carcinoma tissues. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:20 with a mouse monoclonal antibody recognizing Estrogen Receptor alpha (Product # MA3-310) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

Experimental details: Immunohistochemistry was performed on normal deparaffinized Human uterus tissue tissues. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:100 with a mouse monoclonal antibody recognizing Estrogen Receptor alpha (Product # MA3-310) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

Experimental details: FIGURE 1 Raloxifene increased ER-alpha protein expression in young and old IVDs, whereas OVX reduced ER-alpha protein expression. (A) Estrogen receptor-alpha (ER-alpha) immunostaining (arrow: presence of stain, arrowhead: absence of stain) in the (B) AF and (C) NP of young-adult (4 months), old (24 months), and OVX (6 months) mice. Data are represented as box plots with mean marked as cross (x), 25/75% deviation lines, and maximum/minimum whiskers. *: control (CON, n = 5/sex/group) vs. raloxifene (RAL); R: CON vs. RAL; S: male vs. female; RxS: interaction, vehicle (VEH, n = 8/group) vs. RAL, SHAM ( n = 4-5/group) vs. ovariectomized (OVX); # : aging effect (4 months vs. 6 months vs. 24 months), p < 0.05. AF, annulus fibrosus; NP, nucleus pulposus. Scale: 100 mum.

Experimental details: Fig. 2 CALML3 as a coregulator of ERalpha affects the expression of ZNF423 and BRCA1. a Interaction of ERalpha and CALML3 in ZNF423 rs9940645 WT or variant genotype breast cancer cells treated with 0.01 nM E2. Co-IP performed by immunoprecipitating the protein complex with anti-ERalpha antibody, followed by immunoblotting for CALML3, or vice versa. b - e CALML3 was knocked down in ERalpha + breast cancer cells homozygous for ZNF423 WT or variant SNP genotypes and followed by treatment with 0.01 nM E2 +- 4-OH-TAM/raloxifene 10 -7 mol/L. ZNF423 and BRCA1mRNA expression levels relative to beta-ACTN shown as the mean of three independent experiments (+- SEM). * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 by two-tailed Student's t test.
