Figure Lengend Snippet: Figure 1 AChE interacts with RanBPM (A) The self-expression assay of the bait. AH109/pGBKT7-AChEC-terminal cells were cultured on SD/-Trp plate or SD/-Trp/-His plates. (B) Library screening. AH109 clones transfected with pGBKT7-AChEC-terminal and human fetal brain library were cultured on SD/-Ade/-His/-Leu/-Trp/X-a-gal plates. The arrows indicate the positive clones (blue clones). (C) The scheme of the two positive clones (A and C6). The putative SPRY domain (amino acids 212–333) is indicated. (D) Clones A and C6 showed strong lacZ reporter activation. Pos., a clone consisting of BD-p53 and AD-SV40 T-antigen was used as the positive control. Neg., a combination of BD-laminC and AD-SV40 T-antigen was used as the negative control; b-galactosidase activity is expressed as a percentage of the positive control. The data are represented as the mean+ SD of three independent transformations. (E,F) HEK293T cells transfected with the indicated expression plasmid for 24 h; the whole-cell lysates were immunoprecipitated with anti-Myc antibody and analyzed by immunoblotting with anti-HA antibody (top panel). Separate aliquots of the lysates were immunoblotted with anti-HA (middle panel) or anti-Myc (bottom panel) to confirm the expression of HA-RanBPM or Myc-AChEC-terminal (or Myc-AChE), respectively. (G) Kidney tissues from the rat model of ischemia/reperfusion injury were immunoprecipitated using the anti-AChE antibody (E70), and analyzed by immunoblotting with the anti-RanBPM antibody (top panel). Separate aliquots of the lysates were immunoblotted with anti-RanBPM (middle panel) or anti-AChE (E70) (bottom panel) to confirm the expression of RanBPM or AChE, respectively, in the rat kidney tissues.

Figure Lengend Snippet: Figure 3 Subcellular distribution of RanBPM and AChE (A,B) Fractionation of HEK293T cell extracts. HEK293T cells were transfected with the indicated expression plasmids. At 24 h after transfection, the cells were fractionated into nuclear (N) and cytoplasmic (C) fractions and analyzed directly by immunoblotting with the anti-HA (first panel) or anti-Myc antibody (second panel). The purity of the nuclear and cytoplasmic fractions was examined by immunoblotting with anti-histone 3 (fourth panel) and anti-a-tubulin antibody (third panel), respectively. (C) Determination of co-localization of AChE and RanBPM by immunofluorescence. HEK293T cells were transfected with Myc-RanBPM and GFP-AChE. At 24 h after transfection, the cells were fixed and incubated with anti-Myc (red), followed by incubation with Rhodamine-conjugated secondary antibodies. The cells were examined by fluorescence microscopy.

Figure Lengend Snippet: Figure 4 Subcellular distribution of RanBPM and AChE after cisplatin treatment (A) HEK293T cell viability was assessed by MTT after treatment with different concentrations of cisplatin for 24 h. The graph shows the mean+ SE of three independent experiments. (B) The transcription level of p73a gene detected by RT–PCR. HEK293T cells were treated with different concentrations of cisplatin for 24 h and then total mRNA was extracted for RT–PCR. (C) Cisplatin of 100 mM or higher induced DNA fragmentation. (D) The amount of RanBPM and AChE in the nuclear fractions increased after treatment with cisplatin. After cotransfection with pCMV-Myc-RanBPM and pEGFP-C1-AChE for 24 h, HEK293T cells were treated with the indicated concentrations of cisplatin for another 24 h. Then, the cells were fractionated into nuclear (N) and cytoplasmic (C) fractions. The cell fractions and the whole-cell lysates were immunoblotted with anti-Myc (left line) or anti-GFP (light line). The graph shows the densitometric values of the proteins in the cytoplasm versus those in the nuclei.

HEK293T cells were cultured without medium changed for 3 days (3D) or 7 days (7D), and then the whole-cell lysates were immunoblotted with anti-capspase 3, or anti-b-actin antibody. (B) The amount of endogenous RanBPM and AChE in the nuclear fractions was increased after long-term culture. HEK293T cells were cultured without medium changed for 2 days (2D), 5 days (5D) or 8 days (8D), and then the nuclear fractions were immunoblotted with anti-AChE (first panel) or anti-RanBPM antibody (second panel, NB 100–1281).

Article Title: Galectin-5 is bound onto the surface of rat reticulocyte exosomes and modulates vesicle uptake by macrophages.

doi: 10.1182/blood-2009-07-231449

Figure Lengend Snippet: Figure 1. Galectin-5 is present on the surface of rat red cells. (A) Freshly isolated reticulocytes or erythrocytes were adsorbed on glass coverslips and processed for immunofluorescence as described in “Fluorescence-activated cell-sorting analysis of exosomes and red cells, fluorescence microscopy of red cells.” Transmission images of red cells (left) and corresponding fluorescence imaging (right) were recorded on cells by the use of purified rabbit anti–galectin-5 antibody followed by incubation withAlexa 488 anti–rabbit antibody. (B) Young reticulocytes and erythrocytes were analyzed by flow cytometry by the use of antibodies raised against Gal-2 (dashed line), Gal-4 (dotted line), and Gal-5 (solid line), already tested for their specificity (top), or the produced anti–galectin-5 serum (solid line) and the preimmune serum (bottom, dashed line). Tinted patterns indicate cell labeling obtained in the absence of primary antibodies. (C) Lymphocytes isolated from rat blood, as described in “Cells,” were analyzed by flow cytometry for Gal-5 (left, solid line), CD47 (middle, solid line) and Syto 16 green (right, solid line). Tinted patterns indicate cell labeling in the absence of primary antibodies. (D) Ghost and raft extracts isolated from reticulocytes or mature erythrocytes, as described in “Red cell subcellular fractionation,” were processed by SDS-PAGE and analyzed by Western blot for the indicated proteins. The molecular mass (kDa) standards are indicated on the left.
