Detection of Recombinant Human IL‑6 by Western Blot.
Western blot shows 25 ng of Recombinant Human IL-6 (Catalog # 206-IL), Recombinant Mouse IL-6 (Catalog # 406-ML) and Recombinant Rat IL-6 (Catalog # 506-RL). PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human/ Primate IL-6 Monoclonal Antibody (Catalog # MAB206) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for IL-6 at approximately 18 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.IL‑6 in Human Skin.
IL-6 was detected in immersion fixed frozen sections of hyperplastic human skin using Mouse Anti-Human/Primate IL-6 Monoclonal Antibody (Catalog # MAB206) at 8 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Recombinant Human IL-6 (Catalog # 206-IL) stimulates proliferation in the T1165.85.2.1 mouse plasmacytoma cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL-6 (2.5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human/Primate IL-6 Monoclonal Antibody (Catalog # MAB206). The ND50 is typically 8.00 - 80.0 ng/mL.Detection of Human IL-6 by Immunohistochemistry
The role of IL‐6 signaling in the upregulation of PD‐L1 and downregulation of NKG2D ligands in CRPC cells. (A) PD‐L1 level in C4‐2siIL‐6/sc and CWRsiIL‐6/sc cell lines (left panel, mRNA level; right panel, protein level). (B) PD‐L1 IHC staining of tumor tissues. Error bars and significance values were obtained by counting positively stained cells in one randomly chosen phase of slides of three different stains. Magnification, 20× (inlet, 100×). (C) Blocking of IL‐6 Ab by neutralizing Ab of IL‐6 and the effect on PD‐L1 level in C4‐2sc and CWRsc cells. Cells were treated with either IL‐6 Ab or control IgG, total RNA extracted, cDNA converted, and the expression of PD‐L1 was compared in qPCR analyses. (D) PD‐L1 level in parental C4‐2 and CWR22Rv1 cells upon the addition of rhIL‐6. Parental cells (C4‐2P and CWR22Rv1P) were treated with rhIL‐6 (20 ng·mL−1) and PD‐L1 mRNA level was analyzed. (E) IHC staining of CRPC patient tumor samples. Two sets of adjacent tumor tissues (both samples, CRPC stage, Gleason score 8, patient age 70, Ningbo hospital in China) were stained with IL‐6 and PD‐L1. Arrows indicate the area showing positive staining of two molecules. (F) NKG2D ligand levels in IL‐6‐expressing cells and in IL‐6‐knockdown cells. Levels of five NKG2D ligands in C4‐2siIL‐6/sc and CWRsiIL‐6/sc cells were analyzed in qPCR analyses. (G) NKG2D ligand levels in parental C4‐2 and CWR22Rv1 cells upon the addition of rhIL‐6. Parental cells (C4‐2P and CWR22Rv1P) were treated with rhIL‐6 (20 ng·mL−1) and the NKG2D ligand levels (mRNA) were analyzed. (H) Flow cytometric analyses of NKG2D and PD‐1 on NK cells. Left two panels, primary NK cells were stained with PE‐NKG2D or APC‐PD‐1 and positive staining was analyzed. Right two panels, flow cytometric analyses of PD‐1 on NK cells, after coculture with tumor cells (6 h of incubation). Primary NK cells were added into tumor cells (1 : 1 ratio, tumor cells/NK cells) and collected after 6 h of incubation. PD‐1 levels in the collected NK cells were analyzed in flow cytometric analysis (using APC‐PD‐1 Ab). *P < 0.05, **P < 0.01, ***P < 0.001.

Activated ADSCs trigger the proliferation and invasion of lung cancer cells by regulating MMP2/9 expression and EMT. a The effects of activated ADSCs on lung cancer cell proliferation were evaluated using the CCK-8 assay. Four lung cancer cell lines were cultured in the presence of ADSC-CM or aADSC-CM, and the optical density at 450 nm was analysed. The cancer cells cultured alone in normal growth medium were used as negative controls. Data from three separate experiments are shown. b The number of lung cancer cells that migrated through 8-μm Transwell membrane pores was counted to determine the changes in the invasive capabilities in response to CM from epidural ADSCs or aADSCs. c MMP2/9, E-cadherin and vimentin expression levels in four lung cancer cell lines treated with ADSC-CM or aADSC-CM were examined by western blotting. Lung cancer cells cultured in an untreated medium served as controls. d Lung cancer cells were treated with neutralizing antibodies against IL-6, isotype controls and aADSC-CM. Lung cancer cell invasion was analysed using a Transwell assay. Lung cancer cells cultured with untreated medium served as negative controls. e Lung cancer cells were treated with neutralizing antibodies against IL-6, isotype controls and aADSC-CM. MMP2/9, E-cadherin and vimentin expression levels in four lung cancer cell lines were analysed using western blotting.
