    R&D Systems mouse anti human egf neutralizing antibody ntab
    (A) ELISA of <t>EGF,</t> TNF-α, IL-6, and TGF-β1 was performed with the culture supernatants of nonadherent NL20, BEAS-2B, and 16HBE 4–6 days after incubation with autocrine CS or BPDE CM compared with the autocrine control CM. ELISA of EGF, TNF-α, and IL-6 was also conducted with the culture supernatants 48 h after exposure to CS in adherent bronchial cell lines. Asterisks indicate a significant difference in concentration (*p < 0.05, **p < 0.01). Relative values are shown as mean ± SD from three independent experiments. (B) Anchorage-independent growth of NL20, BEAS-2B, and 16HBE cells was measured using MTT 5–6 days after the administration of recombinant human EGF, TNF-α, and IL-6. The MTT assay was performed for autocrine CS CM-incubated nonadherent NL20 and BEAS-2B cells four and five days after <t>EGF-neutralizing</t> antibody <t>(NtAb)</t> treatment, respectively, and for autocrine CS CM-incubated nonadherent 16HBE cells, five days after TNF-α NtAb treatment. The MTT assay was also performed for autocrine CS CM-incubated nonadherent bronchial cell lines five days after IL-6 NtAb administration. Asterisks indicate a significant difference in growth (*p < 0.05, **p < 0.01). Relative values are shown as mean ± SD from three independent experiments. (C) Expression of BRD4 and EZH2 in nonadherent 16HBE cells three days after the administration of recombinant human TNF-α determined using western blotting and the expression of BRD4 and EZH2 3–4 days after treatment of nonadherent NL20 and BEAS-2B cells with recombinant human EGF.

(C) HaCaT cells treated with CM from TNIIIA2-induced senescent WI-38 cells were incubated with either an anti-HB-EGF neutralizing antibody or isotype control and then subjected to a WST-8 (D) or colony formation (E) assay. (F) WI-38 cells were treated with either TNIIIA2 (50 μg/mL) or NaB (4 mM) to induce cellular senescence, as described in the Materials and Methods. HB-EGF and GAPDH mRNA levels were then measured by semi-quantitative PCR. In (G and H), HaCaT cells were treated with recombinant human HB-EGF, and the cells were subjected to a WST-8 assay on day 2 (G) or colony formation assay on day 10 (H). Data are presented as means ± SD, *P < 0.05, **P < 0.01.

    A model of malignant transformation of preneoplastic cells via factors secreted from TNIIIA2-induced senescent fibroblasts. Activation of β1-integrin by TNIIIA2 induces fibroblast senescence. Factors secreted by TNIIIA2-induced senescent fibroblasts, including HB-EGF, are involved in the malignant transformation of preneoplastic cells. Inactivation of β1-integrin by peptide FNIII14 inhibits TNIIIA2-induced cellular senescence. Created using BioRender.com.
