Figure Lengend Snippet: Figure 1 Expression of HOXB7 and bFGF genes in A375 melanoma, SkBr3 mammary carcinoma and HOXB7-transduced SkBr3. (a) RNase protection analysis. Riboprobes (R) and protected fragments (P) are shown on the right, and molecular size (base pairs) markers (MWM) (pGEM4Z HpaII) on the left. b-actin expression is shown as internal control. (b) Northern blot analysis. b2 microglobulin expression is shown as internal control. (c) Western blot analysis of bFGF produced by A375 melanoma, SkBr3 mammary carcinoma and HOXB7-transduced SkBr3 cells

Figure Lengend Snippet: Figure 3 (a) Role of bFGF for SkBr3/HOXB7 cell growth in low serum. Growth kinetics of parental and HOXB7-transduced SkBr3 cells maintained in 10% or 1% FCS were compared. Cell growth was monitored over the indicated time intervals by methylene blue inclusion, as indicated in Materials and methods. (b) Eect of exogenous rbFGF on SkBr3 cell growth. Growth curves of cells maintained in 1% FCS plus dierent concentra- tions of rbFGF evaluated by methylene blue inclusion

Figure Lengend Snippet: Enhanced FGFR3 activation in vemurafenib-resistant B-RAF V600E melanoma cells. A, phospho-RTK antibody array analysis. Cell lysates from A375, M14, A375-R1, and M14-R cell lines were incubated on RTK antibody array for 16 h and phosphorylation status was determined as described under “Experimental Procedures.” Each RTK antibody is spotted in duplicate. Supplemental Table S2 describes the list of RTKs and the layout of the antibody array. B, confirmation of phospho-FGFR3 levels by Western blot analysis. Protein levels of total and phosho-FGFR3 were assessed using immunoblotting. C, ELISA analysis of secreted FGF2 in the conditioned media obtained from A375, A375-R1, M14, and M14-R cells. ELISA was performed as described in “Experimental Procedures.”

Article Snippet: Cells were cultured for 48 h in growth medium described above, and the conditioned medium samples (cell free culture supernatant) were analyzed for concentrations of human FGF2 using human FGF2 Quantikine ELISA Kit (R&D Systems).
