Article Title: Antifungal Mechanism of Action of Lactoferrin: Identification of H + -ATPase (P 3A -Type) as a New Apoptotic-Cell Membrane Receptor

doi: 10.1128/AAC.03130-15

Figure Lengend Snippet: Identification of the plasma membrane lactoferrin-binding protein of C. albicans. (A) Far-Western blot of interaction between lactoferrin and an ∼100-kDa protein. Partial SDS-PAGE images show the protein bands corresponding to the bands detected by far-Western blotting. Lane 1, human lactoferrin (hLf). Lane 2, plasma membrane (PM) proteins incubated with hLf. hLfb, hLf bound to an ∼100-kDa protein. Lane 3, PM proteins incubated with anti-Pma1p. Far-Western membranes were stripped and challenged with either anti-hLf biotinylated antibody (lanes 1 and 2) or mouse anti-Pma1p monoclonal antibody (lane 3). The location of anti-Pma1p using a secondary antibody (IgG biotinylated antibody) is shown. Binding of biotinylated antibodies was visualized by addition of streptavidin-HRP polymer conjugate and a chromogenic substrate. (B) Identification of the plasma membrane hLf-binding protein by LC-MS/MS MRM. Nine trypsin peptides were detected by LC-MS/MS analysis corresponding to the C. albicans protein Pma1p (UniProt entry P28877; PMA1_CANAX). MW, molecular weight; m/z, experimentally determined mass-to-charge ratio; dotp, dot product.

Article Snippet: Goat anti-mouse IgG secondary biotinylated antibody and anti-bovine serum albumin (BSA) antibody were purchased from Abnova Co. (Taipei, Taiwan).

Article Title: Connective tissue growth factor promotes articular damage by increased osteoclastogenesis in patients with rheumatoid arthritis

doi: 10.1186/ar2863

Figure Lengend Snippet: Connective tissue growth factor expression in synovial tissue of patients with rheumatoid arthritis. The representative results of HE staining (Figure 2A), immunofluorescence anti-CTGF antibody staining (Figure 2B; green), and anti-F4/80 antibody staining (Figure 2C; red) are shown using surgical samples from RA and OA patients. The samples were counterstained by DAPI (blue) for nuclear staining and merge images are shown (Figure 2D). A strong expression of CTGF and F4/80 was observed in the samples of RA compared to OA and the CTGF expression cells were not overlapped with F/40 expression cells indicating that CTGF is upregulated in synovial fibroblasts rather than macrophages.

Article Snippet: The serum level of CTGF in human sera was evaluated by a sandwich ELISA system using two different anti-human CTGF antibodies; monoclonal anti-human CTGF antibody (R&D System, Cat#MAB660) and biotinated anti-human CTGF antibody (R&D System, Cat#BAF660).

Figure Lengend Snippet: Synergistic effects of connective tissue growth factor on M-CSF/sRANKL-mediated osteoclastic function. Figure 5A shows the results of the resorption of osteoclasts on calcium phosphate. Vacant regions indicated by arrows represent the areas where the osteoclasts actually absorbed. There was no vacant region in negative control cells (M-CSF alone). In contrast to negative control, significant vacant regions were observed in osteoclasts induced by M-CSF/sRANKL. CTGF further expanded the vacant areas in combination with M-CSF/sRANKL and anti-CTGF antibody neutralized this effect. Figure 5B shows the levels of expression of osteoclasts specific proteases (MMP-9 and cathepsin-K) measured by quantitative real time RT-PCR. Synergistic effect of CTGF was also observed for M-CSF/sRANKL-mediated osteoclastogenesis. Bars in Figure 5B indicate the SD.

doi: 10.1186/ar2863

Figure Lengend Snippet: Connective tissue growth factor mediate ERK1/2 and focal adhesion kinase activation through integrin αVβ3 signal transduction. Figure 6A shows the immnoprecipitation and immunoblotting analysis. The cell extracts of osteoclasts stimulated with recombinant CTGF (10 or 50 ng/ml) at 60 minutes were precipitated using anti-integrin αVβ3 antibody and subsequently blotted with anti- phosphorylated ERK1/ERK2, conventional ERK1/ERK2, and integrin αVβ3 antibodies respectively. The phosphorylated ERK1/ERK2 was recruited with integrin αVβ3 by CTGF stimulation. Figure 6B shows the immunoblotting analysis using anti- phosphorylated FAK, conventional FAK, and β-actin antibodies in the osteoclasts extracts treated with CTGF (10 ng/ml) at 5, 15, 60, and 120 minutes in the presence or absence of anti-CTGF antibody (1 μg/ml). CTGF stimulation resulted in phosphorylation of FAK from 60 minutes and this effect was neutralized by anti-CTGF antibody suggesting activation of signal transduction pathways through integrin αVβ3.
