Figure Lengend Snippet: Recombinant and cell-derived sTNFR1 and sTNFR2 have a protective effect against TNFα-induced expression of pro-metastatic chemokines in MDA-MB-231 cells. MDA-MB-231 cells (MDA) were stimulated by TNFα (0.5 ng/mL) that was pre-incubated with rsTNFR1 (150 ng/mL), rsTNFR2 (500 ng/mL), rsTNFR1 + rsTNFR2 (concentrations as before) or their vehicle. When indicated, the cells were cultured prior to TNFα stimulation with TAPI-0 (5 µg/mL) or its vehicle for 3 h, as well as during cytokine stimulation (TAPI-0 did not affect tumor cell growth). The concentrations of rsTNFR1 and rsTNFR2 were selected as described in . CM were collected following 24 h stimulation, and CXCL8 ( A ) and CXCL1 ( B ) levels were determined by ELISA. A representative experiment of n = 3 is presented. *** p < 0.001, ** p < 0.01, * p < 0.05. # p < 0.1. NS, not significant. Black asterisks denote the differences in chemokine levels between TNFα-stimulated cells and vehicle-treated cells. Orange asterisks denote the differences in chemokine levels between TAPI-0-treated cells and cells treated by its vehicle. Statistical analyses were performed as described in .

Article Snippet: To determine the impact of recombinant soluble (rs) TNFR1 and rsTNFR2 on induction of TNFα-induced chemokine production, rsTNFR1 (150 ng/mL, #636-R1, R&D Systems), rsTNFR2 (500 ng/mL, #1089-R2, R&D Systems), both of them together or a vehicle control were incubated with TNFα (0.5 ng/mL, #300-01A, PeproTech) for 60 min at room temperature.

Figure Lengend Snippet: Recombinant and cell-derived sTNFR1 and sTNFR2 have a protective effect against TNFα-induced expression of pro-metastatic chemokines in BT-549 cells. BT-549 cells (BT) were stimulated by TNFα (0.25–0.5 ng/mL) that was pre-incubated with rsTNFR1 (150 ng/mL), rsTNFR2 (500 ng/mL), rsTNFR1 + rsTNFR2 (concentrations as before) or their vehicle. When indicated, the cells were cultured prior to TNFα stimulation with TAPI-0 (5 µg/mL) or its vehicle for 3 h, as well as during cytokine stimulation (TAPI-0 did not affect tumor cell growth). The concentrations of rsTNFR1 and rsTNFR2 were selected as described in . CM were collected following 24 h stimulation, and CXCL8 ( A ), CXCL1 ( B ) and CCL5 ( C ) levels were determined by ELISA.
