Figure Lengend Snippet: Fig. 6. Recruitment of YY1 polycomb and RNAi machinery components. A) Bar graph of qRT-PCR for primiRNA 16, following RNA ChIP assay using YY1 antibody with or without DNase treatment in U2os pBlock-it cells. *p b 0.01 vs. input and IP:IgG; **p b 0.01 vs. input and IP:IgG. B) Bar graph of qRT-PCR for primiRNA 16, after RNA ChIP assay using YY1 or IgG and then Dicer antibodies, with or without DNase treatment in U2os pBlock-it cells. ** p b 0.001 vs. input and IP:IgG. C) qRT-PCR for primiRNA 16, after RNA ChIP assay using YY1 or IgG and then Ago1 antibodies, with or without DNase treatment in U2os pBlock-it cells. D) qRT-PCR for primiRNA 200b/c after RNA ChIP assay with or without DNase treatment using YY1 antibody in U2os pBlock-it cells. * and **p b 0.001 vs. input and IP:IgG. E) Bar graph of qRT-PCR for primiRNA 200b/c after RNA ChIP assay with or without DNase treatment using YY1 or IgG and then Dicer antibodies in U2os pBlock-it cells.*and **p b 0.001 vs. input and IP:IgG. F) qRT-PCR for primiRNA 200b/c with or without DNasi treatment using YY1or IgG and then Ago1 antibodies in U2os pBlock-it cells. *and **p b 0.001 vs. input and IP:IgG. All data are calculated with 2−ΔΔCT method and reported as fold enrichment over non immunorecipitated RNA (input) amplified with specific set primers and represent mean values of three different experiments performed in triplicate ± S.D. RNA was also immunoprecipitated with IgG antibody and amplified with specific set primers as experimental control. G) Representative western blot analysis after immunoprecipitation of protein extracts from U2os pBlock-it cells. YY1 antibody immunopre- cipitation and western blot with Dicer antibody and vice versa. Immunoprecipitation with YY1 antibody and detection with Ago1 antibody and vice versa. IgG immunoprecipitation was used as experimental control.
