Figure Lengend Snippet: In vitro experiments demonstrate the impact of ODC1 on macrophage polarization. (A) Flow cytometry analysis of CD206 + M2 macrophages and CD86 + M1 macrophages after co-culture of M0 THP-1 cells with DLBCL cell lines overexpressing or knocking down ODC1. (B) ELISA measurement of cytokine levels in the supernatants after co-culture with different DLBCL cell lines. (C) RT-PCR analysis of M1/M2 marker gene expression in macrophages after co-culture with different DLBCL cell lines. (D) Plasmid-mediated overexpression and knockdown of ODC1 in THP-1 cell lines, with western blotting (upper panel) and RT-PCR (lower panel) used to detect ODC1 protein expression and mRNA levels. (E) Flow cytometry analysis of CD206 + M2 macrophages and CD86 + M1 macrophages in THP-1 cells with ODC1 expression discrepancy. (F) ELISA measurement of cytokine levels in the supernatants from THP-1 cells with ODC1 expression discrepancy. (G) RT-PCR analysis of M1/M2 marker gene expression in macrophages from different groups. The unpaired t -test was used to assess statistical differences between two groups. * P < 0.05; ⁎⁎ P < 0.01; ⁎⁎⁎ P < 0.001; ⁎⁎⁎⁎ P < 0.0001.
Article Snippet: Subsequently, AF488 conjugated anti-human CD68 antibody (clone # Y1/82A, Elabscience), APC conjugated anti-mouse CD206 antibody (clone # C068C2, Elabscience), or PE conjugated anti-human CD86 antibody (clone # BU63, Elabscience) were added, and the cells were incubated in the dark at room temperature for 30 min. After centrifugation, the cells were resuspended in 200 μL of PBS with 1 % BSA and analyzed using flow cytometry.
