Effects of LPS on expression of ARIP2 in Raw264.7 cells. (A) ARIP2 mRNA expression was examined by RT-PCR in Raw264.7 cells treated with LPS for 12 h. Lane 1, Control; Lane 2, LPS 200 ng/ml; Lane 3, LPS 500 ng/ml. The graph represented the relative levels of ARIP2 mRNA in three separate experiments, and the mRNA levels of control group were adjusted to 100%. *P < 0.05, **P < 0.01, compared with control. (B) Expression of mature ARIP2 protein in Raw264.7 cells were detected by immunocytochemical staining with normal rabbit IgG as control staining (a) and with anti-ARIP2 antibody 12 h after untreated (b) or treated with LPS 500 ng/ml (c). Arrows represented ARIP2 positive cells (200×). (C) Levels of ARIP2 protein expression were examined by Western blotting in Raw264.7 cells treated with LPS for 12 h. Lane 1, Control; Lane 2, LPS 200 ng/ml; Lane 3, LPS 500 ng/ml. The graph represented the relative levels of ARIP2 protein in three separate experiments, and the protein levels of control group were adjusted to 100%. **P < 0.01, compared with control. Full-length blots/gels are presented in Supplementary Figure 2.
