Figure Lengend Snippet: Figure 1 Semiquantitative RT-PCR and real-time PCR for Furin, TACE and AREG genes expression. (a) RT-PCR analysis of Furin, TACE and AREG mRNA extracted from SGEC treated with anti-Ro/SSA autoantibodies. M, marker; control, untreated SGEC; HIgG, SGEC treated with IgG fractions extracted from sera of healthy donors; anti-Ro, SGEC treated with anti-Ro/SSA autoantibodies. RT-PCR of GADPH was used as control. Band intensities were analyzed by densitometry (b). (c) Real-time PCR for Furin, TACE and AREG genes expression. Representative histograms of mRNA levels of Furin, TACE and AREG in untreated SGEC (control), SGEC treated with healthy IgG (HIgG), anti-Ro/SSA autoantibodies (anti-Ro). The mRNA levels of the housekeeping gene, b-2 microglobulin, were quantified between untreated control cells and variously treated cells (data represent the mean±s.e. of five independent experiments).

Article Snippet: Membranes were incubated for 90 min with rabbit anti-human Furin polyclonal antibody (pAb), goat antihuman TACE pAb (both from Santa Cruz Biotechnology, Santa Cruz, CA, USA), mouse anti-human AREG mAb (R&D Systems, Minneapolis, MN USA), and for 30 min with the relative secondary antibodies-HRP conjugates (Santa Cruz Biotechnology).

Figure Lengend Snippet: Figure 2 Analysis of Furin, TACE and AREG expression in anti-Ro/SSA Abs-treated SGEC. (a) Flow cytometric analysis of Furin, TACE and AREG expression in SGEC after anti-Ro/SSA Abs treatment. Examples of flow cytometric images from one representative experiment. (A) Furin expression analysis in untreated and anti-Ro/SSA or HIgG-treated SGEC; (B) intracellular active TACE expression analysis in untreated and anti-Ro/SSA or HIgG-treated SGEC; (C) AREG expression analysis in untreated and anti-Ro/SSA or HIgG-treated SGEC. (b) Western blot analysis of Furin, TACE and AREG proteins expression in SGEC treated or not with anti-Ro/SSA. Immunoblotting gave rise to bands of the expected size (97 kDa for Furin, 80 kDa for active TACE and 50 kDa for AREG). b-Actin was used as protein loading control. (c) Detection of soluble AREG by ELISA. Secreted AREG was detected by ELISA in the conditioned medium. Control, untreated SGEC; HIgG, SGEC treated with IgG fractions extracted from sera of healthy donors; anti-Ro, SGEC treated with anti-Ro/SSA autoantibodies. (Data represent the mean±s.e. of four independent experiments).
