Figure Lengend Snippet: FIG. 1. Western blot analysis of porcine uterine protein extract at Day 12 of gestation. a) Molecular weight markers (x 10 3) (lane 1), total CM-50 sephadex-extracted uterine protein (25 g, lanes 2, 4, and 6), human recombinant bFGF (100 ng, lanes 3 and 5). Lanes 1 and 2 were stained for total protein by colloidal gold stain. Lanes 3 and 4 were in- cubated with anti-bFGF antibody (0.15 Ixg/ml). Lanes 5 and 6 were in- cubated with rabbit IgG (0.15 .Lg/ml). b) Sephadex-extracted uterine pro- tein (25 jIg, stained for total protein by colloidal gold) in nonreducing 7.5-15% PAGE. Bovine aFGF (500 ng, lanes 2, 4, and 6) and sephadex extract (25 g, lanes 3, 5, and 7). Immunoreactive aFGF bands are ob- served in lanes 2 and 3 (incubated with anti-aFGF antibody). The absence of these bands is noted in lanes 4 and 5 (anti-aFGF antibody immunoab- sorbed with bovine aFGF) and in lanes 6 and 7 (incubated with rabbit IgG).

Article Snippet: For aFGE PAGE was performed using 7.5-15% acrylamide gel and bovine aFGF (cat. #132-FA; R&D Systems, Minneapolis, MN) as standard.

Article Title: Characterization of FN1-FGFR1 and novel FN1-FGF1 fusion genes in a large series of phosphaturic mesenchymal tumors.

doi: 10.1038/modpathol.2016.137

Figure Lengend Snippet: Figure 2 Western blot analysis of PMT-50. The fusion protein (indicated with arrows), with a molecular size of estimated 180– 200 kDa, is stained with both fibronectin and FGF1 immunoblot- ting. Normal fibronectin (4250 kDa) is also expressed by the tumor. No conspicuous expression of normal FGF1 is observed in PMT-50, in contrast to PMT-2 (harboring FN1–FGFR1 fusion gene). Weak expression of normal FGFR1 (about 100 kDa) is also observed in PMT-50.

Article Snippet: The fusion protein was characterized with western blot as previously described.8 Primary antibodies against fibronectin (1:1000 dilution; Abcam, Cambridge, UK), FGF1 (clone B-3; 1:500 dilution; Santa Cruz Biotechnology, Dallas, TX, USA), and FGFR1 (clone D8E4; 1:1000 dilution; Cell Signaling Technology, Danvers, MA, USA) were used.

doi: 10.1038/modpathol.2016.137

Figure Lengend Snippet: Figure 3 Examples of fluorescence in situ hybridization results. (a) PMT-19 shows juxtaposition of 5′ FN1 and 3′ FGFR1 signals, while the 5′ and 3′ ends of FGFR1 were broken apart. By contrast, PMT-42 (b) and PMT-5 (c, 3-dimensional reconstruction by deconvolution microscopy) reveal juxtaposition of signals of 5′ FN1, 5′ FGFR1, and 3′ FGFR1, which implies more complex forms of rearrangement and could evade detection by FGFR1 break-apart probes alone. (d) PMT-50 harbors break-apart FGF1 gene. (e) By using mixed FN1–FGFR1 and FGF1 probes, FN1–FGF1 fusion (blue–green fusion) is disclosed in PMT-31.

Figure Lengend Snippet: Figure 4 (a-c) FGFR1 immunohistochemistry (with corresponding hematoxylin and eosin staining) shows strong immunoreactivity in cases with (a: PMT-20) and without (b: PMT-23 and c: PMT-15) FN1–FGFR1 fusion, presenting mainly cytoplasmic staining pattern. Areas of heavy matrix deposition (c) also often present FGFR1 immunoreactivity. As internal controls, osteoclastic giant cells in (a and b), as well as skeletal muscle cells in (c), are negative (indicated with asterisks). (d–f) FGF1 immunohistochemistry (with corresponding hematoxylin and eosin staining) exhibits chiefly cytoplasmic staining whereas extracellular immunoreactivity (d: PMT-50 and e: PMT-58) or nuclear staining (f: PMT-47) is sometimes observed.

doi: 10.1038/modpathol.2016.137

Figure Lengend Snippet: Figure 5 The schematic diagram of proposed tumorigenesis mechanisms of phosphaturic mesenchymal tumor. (1) FN1–FGFR1 proteins might use the self-assembly and fibronectin-binding domains of the FN1 part to dimerize, perhaps with the assistance of extracellular matrix (such as heparin). The FGFs (eg, FGF1 and FGF23) secreted by the tumor cells might bind the ligand-binding domains of the FGFR1 part to facilitate the dimerization and activation of the fusion protein. (2) FN1–FGF1 protein is probably secreted and, with the assistance of heparin, might dimerize and bind the membranous FGFR1 in a 2:2 ternary fashion. (3) α-Klotho serves as an obligatory co-receptor for the FGF23–FGFR1 binding and, when overexpressed in osteocytes or their FGF23-secreting precursors, might allow FGF23 to activate FGFR1. The three pathways converge in the activation of FGFR1 signaling, which might upregulate the expression of FGF23. The nuclear translocation of FGF1 proteins, in either native or chimeric form, might also have a role in the tumorigenesis.

Figure Lengend Snippet: A2780DPP cells were lentivirally transduced with an shRNA construct targeting FGF1 or an empty vector control and FGF1 expression assessed using a qRT-PCR analysis and b immunoblot analysis (EV empty vector). MTT assays were used to assess the effect of FGF1 knockdown on sensitivity to c cisplatin (0–25.33 µM) and d carboplatin (0–85.12 µM). FGF1 was overexpressed in A2780 cells using an FGF1-EGFP fusion plasmid and e immunoblot analysis and f green fluorescence imaging used to confirm FGF1 expression. MTT assays were used to assess the influence of FGF1 over-expression on sensitivity to g cisplatin (0–25.33 µM) and h carboplatin (0–85.12 µM). Results represent three independent experiments. Pairwise comparisons of mean IC 50 values and relative gene expression were performed using Student’s t -tests. Scale bar = 100 µm. * p < 0.05, ** p < 0.01, *** p < 0.001.
