    Article Title: Mapping the sclerostin– LRP4 binding interface identifies critical interaction hotspots in loops 1 and 3 of sclerostin
    Article Snippet: Data analysis was performed using flowjo software (BD, Ashland, OR, USA). .. For library sorting, the cells were incubated with 5 n m soluble His‐tagged human LRP4 or 650 n m soluble His‐tagged mouse LRP6 (R&D Systems, Minneapolis, MN, USA) and 1 : 100 affinity‐purified chicken anti‐c‐Myc antibody (Immunology Consultants Laboratory, Inc., Portland, OR, USA) for 1 h at room temperature, followed by double staining with a 1 : 50 FITC‐conjugated anti‐6 × His‐tag monoclonal antibody (Invitrogen, Waltham, MA, USA) and 1 : 50 Alexa FluorTM 555‐labeled goat anti‐chicken IgY (H + L) antibody (Invitrogen) for 20 min in the dark on ice. .. The desired populations were collected on an iCyt Synergy FACS apparatus (Sony Biotechnology, San Jose, CA, USA) and allowed to recover at 30 °C with shaking at 300 rpm in SDCAA medium until the culture reached an OD 600 of 8.

    Article Title: Competitive blocking of LRP4-sclerostin binding interface strongly promotes bone anabolic functions.
    Article Snippet: Induction of bone formation by Wnt ligands is inhibited when sclerostin (Scl), an osteocyte-produced antagonist, binds to its receptors, the low-density lipoprotein receptor-related proteins 5 or 6 (LRP5/6).. Recently, it was shown that enhanced inhibition is achieved by Scl binding to the co-receptor LRP4.. However, it is not clear if the binding of Scl to LRP4 facilitates Scl binding to LRP5/6 or inhibits the Wnt pathway in an LRP5/6-independent manner.

    Article Title: Competitive blocking of LRP4–sclerostin binding interface strongly promotes bone anabolic functions
    Article Snippet: The expression of displayed proteins was detected with 1:50 mouse anti-c-Myc antibody, 9E10 (Abcam, Cambridge, MA, USA) followed by 1:50 anti-mouse IgG (whole molecule)—R-phycoerythrin antibody produced in goat (Sigma-Aldrich). .. For binding analysis of displayed Scl WT or Scl N93A , cells were incubated with different concentrations of either soluble His-tagged mouse LRP6 (R&D Systems) or with soluble His-tagged human LRP4 (R&D Systems) for 2 h at room temperature, following detection with a 1:50 FITC-conjugated anti-6xHis-tag monoclonal antibody (Invitrogen). .. For competition binding between LRP4 and LRP6, cells displaying Scl were pre-incubated with soluble LRP4 (1, 5 or 200 nM) for 2 h, followed by incubation with 200 nM soluble human LRP6-Fc (R&D Systems) for 2 h and detection with a 1:50 monoclonal anti-human IgG (Fc specific)—FITC antibody produced in mouse (Sigma Aldrich).

    AAV9-X1.1 has enhanced potency in ( a ) macaque and ( b ) human primary brain microvascular endothelial cell culture (black data points), which decreases to AAV9 levels with Mesd inhibition of LRP6 (blue data points). 4 biological replicates were performed and quantified for each condition. Bars indicate the mean value. MOI: multiplicity of infection. c AAV9-X1.1 has enhanced potency in human pluripotent stem cell (hPSC)-derived midbrain dopaminergic neuronal culture (black data points), which decreases to AAV9 levels with Mesd inhibition of LRP6 (blue data points). 5 biological replicates were performed and quantified for each condition. d Quantification of LRP6 and NeuN immunohistochemistry confirms that LRP6 expression is largely restricted to mature neurons (20 biological replicates) and that the LRP6-dependent enhanced potency of AAV9-X1.1 is enriched in this population (5 biological replicates for each condition, Mesd inhibition condition in blue).

    Article Snippet: Lyophilized mouse LRP6 (AA 20-1366) with a 6xHis tag, N-terminal (E1E2) and C-terminal (E3E4) fragments of mouse LRP6 extracellular domain (N-half: AA 20-628, C-half: AA 629-1244) tagged with mouse IgG 2a Fc, full-length human LRP6 (AA 20-1368) tagged with human IgG 1 Fc, LRP5 (AA1-1383) with a 6xHis tag, and SOST protein were purchased from Bio-Techne (cat# 2960-LR-025, 9950-LR-050, 9954-LR-050, 1505-LR-025, 7344-LR-025/CF, 1406-ST, respectively).
