(Zeiss, Jena, Germany). mCherry fluorescence was detected employing the 561 nm laser plus a 578-696 nm bandpass filter. The cells had been examined using a Zeiss LD C-apochromat 40?1.1 water objective. Confocal pictures represent confocal slices of approximately 1 m.Further filesAdditional file 1: Effect of intracellular retention of de novo synthesized CAgp130 on all round receptor expression. T-REx-293-WTgp130-YFP and T-REx-293-CAgp130-YFP have been left untreated or expression was induced with 20 ng/ml dox for the indicated periods of time. Cells were simultaneously treated with one hundred ng/ml brefeldin A or MeOH (vehicle). General receptor expression was assessed by FACS analysis with the fluorescent tag. Non-induced cells (filled histograms) had been utilized as unfavorable controls. Added file 2: Binding of neutralizing gp130 Abs to WTgp130 and CAgp130. T-REx-293-WTgp130-YFP (upper panel) and T-REx-293-CAgp130-YFP (lower panel) were not incubated with dox (dotted line) or expression was induced with 20 ng/ml dox for 24 h (solid line). Surface receptor was stained with gp130 Abs B-P8, B-P4, B-T2 and B-R3 and binding of primary Abs was assessed by an APC labeled secondary Ab. Non-treated cells (filled histograms) serve as negative controls.Abbreviations IHCA: Inflammatory hepatocellular adenoma; CAgp130: Constitutively active del(Y186-Y190)gp130; Dox: Doxycycline; Ab: Antibody; WB: Western blot; TCL: Total cell lysate; IP: Immunoprecipitation.
