- Western blot analysis of Filamin was performed by loading 7.5 µg of HeLa cell lysate per well onto an SDS-PAGE gel. Proteins were transferred to a nitrocellulose membrane and blocked with 5% milk for 1 hour at room temperature. The membrane was probed with a Filamin monoclonal antibody (Product # MA5-11705) at a dilution of 1:200 overnight at 4C, washed in TBST, and probed with an HRP-conjugated goat anti-mouse IgG secondary antibody at a dilution of 1:10,000 for 1 hour at room temperature. Detection was performed using chemiluminescent substrate. Data courtesy of the Innovators Program.

- Western blot was performed using Anti-Filamin A Monoclonal Antibody (FLMN01 (PM6/317)) (Product # MA5-11705) and a 180kDa band corresponding to Filamin A was observed across all cell lines tested except LNCaP and HEK-293 which are known to have low expression of Filamin A (DOI: 10.18632/oncotarget.9472). Whole cell extracts (50 µg lysate) of DU 145 (Lane 1), LNCaP (Lane 2), HeLa (Lane 3), HEK-293 (Lane 4) and A549 (Lane 5) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0321BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1µg/mL dilution) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

- Immunofluorescence analysis of Filamin Antibody was performed using 70% confluent log phase Ramos 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 Filamin A (FLMN01 (PM6/317)) Mouse Monoclonal Antibody (Product # MA5-11705) at 2 µg/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 Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with Filamin A Monoclonal Antibody (FLMN01 (PM6/317)) (Product # MA5-11705) at 2µg/mL dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32766), (1:2000 dilution), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b: Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing predominantly cytoplasmic localization. Panel e represents HEK-293 cells showing lower expression of Filamin A. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

- Figure 3 PERK-deficient GG16 cells are impaired in cellular adaptation to increasing stiffness which is linked with aberrant FLNA expression. ( A , E ) GG16-WT and PERK-KO cells were cultured for 6 days on hydrogels with different stiffnesses and stained with Dapi TM (Blue), Alexa fluor TM 546-Phalloidin (Red), and FLNA--Alexa fluor TM 488 (Green). Cell morphology, F-Actin, and FLNA expression was quantified and is depicted in ( B - D ) and ( F - H ) for GG16-WT and PERK-KO cells, respectively. Cell morphology (from round to elongated), F-Actin, and FLNA expression altered gradually in a stiffness-dependent manner in GG16-WT cells, which was not seen in PERK-deficient cells. * p

- Fig 4 miR-200c regulates migration associated genes such as filamin A. (a) A proteomic analysis of a TALENs knock-out (KO) of miR-200c in MCF7 cells revealed a set of proteins with differential expression, of which 50% are involved in migratory processes and are shown in the table. (RT qPCR showed that after adding 5 mug / ml doxycycline for 48 h the expression of FLNA mRNA (b) as well as filamin A protein(c) (normalized to tubulin) decreased significantly in MDA-MB 231 TRIPZ 200c cells. (d) Immunofluorescence staining of filamin A (green) and DAPI (blue) in MCF7 Ctrl and KO 200c showed significantly increased relative intensity of filamin A, in contrast to (e) the MDA-MB-231 cells which showed a strong decrease in filamin A intensity after induction of miR-200c (all N = 3; error bars indicate standard deviation SD; * p
