Figure Legend Snippet: Hotairm1 binding to S100A9 protein in MDSCs from septic patients. PBMCs were isolated from early and late septic patients and depleted of the HLA-DR + cells using biotin-coupled anti-HLA-DR antibody and anti-biotin microbeads, followed by the positive selection of CD33 + LOX1 + cells with biotin-coupled anti-CD33, anti-CD11b, and anti-LOX1 antibodies. (A) The CD33 + CD11b + LOX1 + HLA-DR- cells were fixed in 0.2% formaldehyde to preserve RNA-protein complexes. The whole cell lysate was incubated with 5 μg of anti-S100A9 or anti-IgG isotype control antibody and then cross-linked to protein G magnetic beads overnight at 4°C. RNA was extracted from the immunoprecipitated protein-RNA complexes by Trizol reagent and used for detecting Hotairm1 by RT-qPCR, using human Hotairm1 primer assay. (B) CD33 + CD11b + LOX1 + HLA-DR- cells from late septic patients were transfected with scramble or Hotairm1 siRNA for 36 h. The cells were treated as described in A , and RT-PCR determined levels of Hotairm1. (C) Whole cell lysate of CD33 + CD11b + LOX1 + HLA-DR-cells were cleared by centrifugation and subjected to immunoprecipitation with S100A9 or IgG isotype control antibody as described in A . The immunoprecipitated protein complexes were assessed by immunoblotting using phospho-S100A9 (Thr113) antibody. The membrane was stripped and reprobed with a phospho-p38 antibody. The results are representative of two experiments. (D) CD33 + CD11b + LOX1 + HLA-DR-cells were transfected with scramble or Hotairm1 siRNA for 36 h, then washed and incubated with 1 μg/ml of bacterial LPS for 12 h. ELISA determined the levels of IL-10 in the culture supernatants. The data are mean ± SD of 5 patients per group.*p < 0.05, vs . early septic or control siRNA; **p < 0.05, vs . Hotairm1 siRNA/early septic; #p < 0.05, vs . control siRNA.
