- Western blot analysis was performed on membrane enriched extracts (30 µg lysate) of MDA-MB-231 (Lane 1), HeLa (Lane 2) and U-87 MG (Lane 3). The blot was probed with Mouse Anti-Cytokeratin 16 Monoclonal Antibody (Product # MA5-13730, 2 µg/mL) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A28177, 0.4 µg/mL, 1:4000 dilution). A 51 kDa band corresponding to cytokeratin 16 was observed across the cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0321BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody using iBind™ Flex Western Starter Kit (Product # SLF2000S). Chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate (Product # 32106).

- Knockdown of Cytokeratin 16 was achieved by transfecting HeLa cells with Cytokeratin 16 specific validated siRNAs (Silencer® select Product # s7991). Western blot analysis (Fig. 1) was performed using whole cell extracts from the Cytokeratin 16 knockdown cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blots were probed with Anti-Cytokeratin 16 Monoclonal Antibody (Product # MA5-13730, 1 µg/mL) and Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A28177, 0.25 µg/mL, 1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig. 2). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to Cytokeratin 16.

- Flow cytometry analysis of Cytokeratin 16 was done on A-431 cells. Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with Cytokeratin 16 Mouse Monoclonal Antibody (Product # MA5-13730, red histogram) or with mouse isotype control (pink histogram) at 3-5 µg/million cells in 2.5% BSA. After incubation at room temperature for 2 hours, the cells were labeled with Alexa Fluor® 488 Rabbit Anti-Mouse Secondary Antibody (Product # A11059) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10, 000 cells were acquired and analyzed for each sample using an Attune® Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

- Figure 1. Gene silencing of Fli1 leads to the induction of SSc-like protein and gene expression profiles in keratinocytes. (A) Immunohistochemistry for Fli1 on the skin sections of healthy controls ( n = 8), lcSSc patients with anticentromere antibody ( n = 8), and dcSSc patients with anti-topoisomerase I antibody ( n = 5). Representative images are shown. Bars, 100 um. (B) The results of Fli1 staining intensity in A were semiquantitatively evaluated with a four-point grading scale. Kruskal-Wallis test followed by Dunn's posthoc test was used. (C) mRNA was isolated from skin epidermal sheets from healthy controls ( n = 4) and dcSSc patients ( n = 6), and gene expressions were analyzed by qRT-PCR. (D) Whole cell lysates from cultured NHKs treated with control nonsilencing SCR or FLI1 siRNA (siFLI1) were subjected to immunoblotting. The values below each blot represent the relative levels of target molecules normalized by controls with densitometry. Representative images of the blots of four independent experiments are shown. (Right) The bar graphs summarize the relative values of the density from these four experiments. (E) The mRNA expression of FLI1 , SNAI1 , and CDH1 in NHKs treated with SCR or siFLI1 was evaluated. Relative expression levels from four independent experiments were normalized to the expression levels treated with SCR. (F) ChIP assay in NHKs was performed with anti-Fli1 antibody and the primers specific for the designated area of the SNAI1 gene promoter.

(D) The results of staining intensity in the epidermis as shown in C were evaluated with semiquantitative scoring. n = 5 per genotype. (E) mRNA expressions of these key molecules were determined by qRT-PCR in the epidermal sheets prepared from the back skin of mice. n = 5 per genotype. Data are shown as mean +- SEM. *, P < 0.05; **, P < 0.01; by two-tailed Mann-Whitney U test. The results are from representative experiments that have been repeated twice in different pairs of mice with similar results. Representative images of immunohistochemistry are shown.
