Experimental details

Flow cytometry analysis of FGFR1 was done on SH-SY5Y cells treated with FGF (100ng/mL, 20 minutes). 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 FGFR1 Mouse Monoclonal Antibody (133100, red histogram) or with mouse isotype control (pink histogram) at 3-5 ug/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 (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 2. Stroma-derived FGF1 is necessary and sufficient for paracrine regulation of MYC. (A) qRT-PCR for the indicated secreted factors in CAF 4414 and hPSC ( n = 3 independent experiments). Data are plotted as fold change in CAF 4414 compared with hPSC (set to 1); all values were normalized to 36B4 as a housekeeping gene. ( B) CAF CM was incubated alone or with FGF1 neutralizing antibody or goat IgG control antibody for 1 h at room temperature, then added to PDAC cells for 3 h. MYC levels in nuclear extracts were analyzed by Western blot (representative of three independent experiments). ( C) ELISA for FGF1 in CM from the indicated cell lines. Data are presented as mean +- SEM; *, P < 0.05; **, P < 0.0025; ***, P < 0.001; ****, P < 0.0001 by Student's t test ( n = 3 independent experiments) compared with CAF 4422 CM (upper line and asterisks) or CAF 4414 CM (lower line and asterisks). (D) IF staining for FGF1 or FGFR1 in the indicated cell lines. Scale bar, 10 um. (E) hPSCs were treated with CM from the indicated PDAC cell lines for 24 h, and FGF1 mRNA was measured by qPCR (left; data were normalized to 36B4 and are presented as mean +- SEM; ***, P < 0.001; ****, P < 0.0001 by Student's t test) and protein measured by Western blot (right). Results represent three independent experiments. (F) mRNA expression levels of the four FGFRs and FGF1 in 40 human PDAC cells from the Cancer Cell Line Encyclopedia database.
