- Western blot analysis of Caspase 9 using 30 µg of 293T lysate. Samples were loaded onto a 10% SDS-PAGE gel and probed with a Caspase 9 polyclonal antibody (Product # PA5-22252) at a dilution of 1:1000.

- Knockdown of Caspase 9 was achieved by transfecting HeLa cells with Caspase 9 specific siRNAs (Silencer® select Product # s2429 & s2430). Western blot analysis (Fig. a) was performed using membrane enriched extracts from the Caspase 9 knockdown cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blots were probed with Anti-Caspase 9 Polyclonal Antibody (Product # PA5-22252, 1:500 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to Caspase 9.

- Western blot analysis was performed on whole cell extracts (30 µg lysate) of HeLa (Lane 1), Jurkat (Lane 2) and A549 (Lane 3). The blot was probed with Anti-Caspase 9 Polyclonal Antibody (Product # PA5-22252, 1:500 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). A 46 kDa band corresponding to Caspase 9 was observed across the cell lines tested.

- Western Blot using Caspase 9 Polyclonal Antibody (Product # PA5-22252). Untreated (–) and treated (+) HeLa whole cell extracts (30 µg) were separated by 10% SDS-PAGE, and the membrane was blotted with Caspase 9 Polyclonal Antibody (Product # PA5-22252) diluted at 1:1,000. The HRP-conjugated anti-rabbit IgG antibody was used to detect the primary antibody.

- Immunofluorescence analysis of Caspase 9 was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Caspase 9 Rabbit Polyclonal Antibody(Product # PA5-22252) at 5 µg/mL in 0.1% BSA, incubated at 4 degree Celsius overnight and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) 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 Nucleus and cytoplasmic localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

- Fig. 4 Regulatory effects of FAT4 on the expression of proteins involved in EMT, Hippo, Wnt-beta-catenin, apoptotic, and retinoblastoma pathways by Western blotting. a . Relative expression variation of proteins. The expression of Vimentin ( p = 0.0001), YAP ( p = 0.0018), beta-catenin ( p = 0.001), Bcl2 ( p = 0.0001), cyclin D1 ( p = 0.0017) and cdk4 ( p = 0.0025) was higher in FAT4 siRNA treated cells as compared to control. beta-actin was used as an internal control. b . Western blot demonstrating bands for protein expression in control and FAT4 knocked cells. Full-length blots are presented in Supplementary figure S 1 . c . The ratio of phosphorylated to total YAP, GSK-3beta, beta-catenin, and retinoblastoma proteins following FAT4 repression. The pYAP/ YAP ratio was lower in FAT4 siRNA treated cells as compared to the control ( p = 0.0286). Similarly, pGSK-3-beta/GSK-3-beta ratio, and pbeta-catenin/beta-catenin ratio was lower in FAT4 siRNA treated cells ( p = 0.018, and p = 0.001 respectively) as compared to control. There was no significant difference in pRb/Rb ratio between FAT4 siRNA treated cells and control. MCAS cells treated with scrambled siRNA was used as control. Data represent mean and standard deviation from at least three independent experiments performed in triplicates

- Figure 1 Effect of apelin on protein expression of apoptotic factors in BeWo cells. The cells were incubated with apelin at doses 2 of (AP2) and 20 (AP20) ng/mL for 24, 48 and 72 h, and subsequently, Western blot analysis was performed to examine the expression of BCL2 (B-cell like lymphoma 2), BAX (Bcl-2-like protein 4), caspase 3, 8 and 9 and p53. Results are shown as stripes on gel image ( A ) and densitometry analysis relative to beta-actin ( B - F ). Experiments were independently performed and repeated three times ( n = 3). The data are arranged as means +- SEM. Different letters indicate significant differences ( p < 0.05) among groups; Control ( C ).

- Figure 5 Effect of vaspin on mRNA and protein expression levels of caspase-3, -8, and -9; BAX (bcl-2-like protein 4), and BCL2 (B-cell lymphoma 2). The cells were treated with 1 and 10 ng/mL vaspin for 24 h, and then, real-time PCR and Western blot analysis were performed to determine levels of caspase-3, -8, and -9 ( A , B ); BCL2 and BAX ( C , D ); and p53 ( E , F ) (full gel images are available in the Supplementary Materials ). Gene expression levels were normalised to glyceraldehyde 3-phosphate dehydrogenase ( GAPDH) , while proteins levels were normalized to actin. Experiments were independently performed and repeated five times ( n = 5). The data are plotted as the means +- SEM. Significance between control and vaspin treatments is indicated by * p < 0.05, ** p < 0.01 and *** p < 0.001; Control (C).
