Figure 1

Expression of TLR9 in glioma cell lines and glioma samples. A. mRNA expression of TLR9 (a) Expression of TLR9 in human U87 glioma cell line(lane1) and human U251 glioma cell line(lane2); (b) Expression of TLR9 in rat glioma cell line C6. (c) Expression of TLR9 in 34 clinical glioma samples (lane1-15, Grade IV gliomas; lane16-28, grade III gliomas;lane 29-34, grade II gliomas). GAPDH was used as positive control. B. Protein expression of TLR9 in human glioma cell lines U87 and U251 with immunofluorescence staining. cytoplasmic localization of TLR9(red fluorescence, Cy3) in U87 and U251 was confirmed by confocal microscopy, nucleus was stained with Hoechst(Blue fluorescence). (a) TLR9 staining in U87 cells. (b) Hoechst staining of nucleus in U87 cells. (c) The combined figure of a and b. (d) negative control, staining of U87 cells with secondary antibody and Hoechst, but without primary anti-TLR9 antibody. (e) TLR9 staining in U251 cells. (f) Hoechst staining of nucleus in U251 cells. (g) The combined figure of e and f. (h) Negative control, staining of U251 cells with secondary antibody and Hoechst, but without primary anti-TLR9 antibody.
