Experimental details: Immunofluorescent analysis of CREB (green) in untreated HeLa cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 15 minutes at room temperature. Cells were then blocked with 5% normal goat serum (Product # 31873) for 15 minutes at room temperature. Cells were probed with a mouse monoclonal antibody recognizing CREB (Product # MA1-083), at a dilution of 1:500 for at least 1 hour at room temperature. Cells were washed with PBS and incubated with DyLight 488 goat-anti-mouse secondary antibody at a dilution of 1:400 for 30 minutes at room temperature. Nuclei were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ArrayScan at 20X magnification.

Experimental details: Immunofluorescence analysis of CREB was performed using 70% confluent log phase MDA-MB-231 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with CREB Monoclonal Antibody (Product # MA1-083) at 5µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing nuclear localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

Experimental details: Enrichment of endogenous CREB protein at specific gene loci using Anti-CREB Mouse Monoclonal Antibody: Chromatin Immunoprecipitation (ChIP) was performed using Anti-CREB Mouse Monoclonal Antibody (Product # MA1-083, 5 µg) on sheared chromatin from 2 million HeLa cells using the MAGnify ChIP system kit (Product # 49-2024). Normal Rabbit IgG was used as a negative IP control. The purified DNA was analyzed by 7500 Fast qPCR system (Product # 4351106) with optimized PCR primer pairs for the promoter of NR4A3, CYR61 gene used as positive control target, and the MYOD, SAT2, used as negative control target. Data is presented as fold enrichment of the antibody signal versus the negative control IgG using the comparative CT method.

Experimental details: Immunoprecipitation of CREB was performed on untreated 293T cells. The antigen:antbody complex was formed by binding 500 µg whole cell lysate with 2 µg of mouse monoclonal antibody recognizing CREB (Product # MA1-083) overnight on a rocking platform at 4øC. The immune-complex was then captured on 50 µL Protein A/G Plus Agarose (Product # 20423). Captured immune-complexes were then washed extensively and proteins eluted with 5X Reducing Sample Loading Dye (Product # 39000). Samples were then resolved on a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to PVDF membrane and blocked with 5% Milk/TBS-0.1%Tween for at least 1 hour. Membranes were then probed with a mouse monoclonal antibody recognizing CREB (Product # MA1-083) at a dilution of 1:1000 overnight rotating at 4øC. Membranes were then washed in TBST and probed with a goat anti-mouse-HRP secondary antibody (Product # 32430) at a dilution of 1:20,000 for at least one hour. Membranes were washed and chemiluminescent detection was performed using Pierce Super Signal West Dura (Product # 34075).

Experimental details: Figure 4 Lamin B1 accumulation reduces cell viability and induces apoptosis signaling pathways: ( A ): Cell viability, cytotoxicity, and apoptosis of transduced cells (ovLMNB1 and GFP) were evaluated by using the ApoTox-Glo Triplex Assay and compared to wild type cells. Analyses from three independent experiments, with ** p < 0.01 vs. corresponding mock-transduced sample (GFP). ( B ): The activation of signaling pathways involved in apoptosis and the expression of downstream targets was evaluated in U87-MG cells 96 h after transduction. The expression or the phosphorylation of the denoted proteins were evaluated. ( C ): CREB phosphorylation was measured in wild type, mock-transduced, and Lamin B1--overexpressing cells. Samples were normalized by using total protein normalization vs. wild type cells. Results are representative of five independent experiments. ( D ): Quantitative analysis of protein expression; wild type cells (WT) were used as reference sample. ** denotes p < 0.01 vs. corresponding mock-transduced sample (GFP).
