    Expression of α-Klotho, vascular endothelial growth factor ( VEGF ) 165 b, VEGF receptor-2 ( VEGFR-2 ) and transient receptor potential canonical-1 ( TRPC-1 ) in dermal microvascular endothelial cells from healthy controls ( H-MVECs ) and patients with systemic sclerosis (SSc) ( SSc-MVECs ). a , b Representative microphotographs of immunocytochemical staining for α-Klotho in H-MVECs ( a ) and SSc-MVECs ( b ) detected with <t>biotinylated</t> secondary antibodies and streptavidin peroxidase. c - f Protein lysates from H-MVECs and SSc-MVECs were subjected to western blotting analysis using anti-α-Klotho ( c ), anti-VEGF 165 b ( d ), anti-VEGFR-2 ( e ) and anti-TRPC-1 ( f ) antibodies. Representative immunoblots are shown. The densitometric analysis of the bands normalized to α-tubulin is reported in the histograms. Data are mean ± SD of optical density ( OD ) in arbitrary units. Student’s t test was used for statistical analysis; p values are indicated in each panel. Results are representative of three independent experiments performed with each one of the five H-MVEC and five SSc-MVEC lines

    Immunofluorescence detection of ZIP4 in human HCC. Part A: Frozen sections of HCC from patients 3, 4 and 11 and normal liver tissue from patient 3 (see Table 1 ) were fixed, permeablized and blocked then ZIP4 was detected using an antipeptide antibody against mouse ZIP4 [26] , [47] . The peptide immunogen is well conserved between mouse and human and specificity of this antibody has been established [26] , [27] , [46] . Sections were washed and incubated sequentially with <t>biotinylated</t> secondary antibody then QDot 655 streptavidin conjugate. Red indicates the presence of ZIP4 whereas blue indicates nuclei stained with DAPI. Adobe Photoshop image capture software was used to capture these images. Part B: Frozen serial sections from patients 3 4 stained with hematoxylin and eosin to reveal the cellular structure of the ZIP4 positive tumors. Arrows point to the boundary of well-circumscribed lesions containing ZIP4 positive hepatocytes.

    Cox-2 expression and interaction with Col10a1 cis-enhancer. ( a ) IHC assay using Cox-2 antibody on sagittal sections of mouse limb (fibula) at E17.5 showed that Cox-2 is strongly expressed in nuclei of hypertrophic chondrocytes but not in resting or proliferative chondrocytes (black box and arrows). Bottom showed higher magnification of the boxed area. Left panel shows no antibody control. ( b ) IHC assay using Cox-2 antibody on tibia sections at 4 weeks' age also detected high-level Cox-2 expression in nuclei of hypertrophic chondrocytes (left panel, black arrows). Right panel shows IHC assay of collagen X, which is mostly expressed extracellular within hypertrophic zone (red arrows). ( c ) EMSA assay detected specific binding complex (black arrow) formed by the Col10a1 enhancer and hypertrophic MCT cell nuclear extracts as previously described. 38 The signal intensity decreased when 200 ng of Cox-2 antibody was added, 500 ng of antibody further reduced the signal, whereas 1000 ng of antibody only showed faint signal (left panel). No signal reduction was seen in parallel experiment in which gradient amount of Nedd4 antibody was used (right panel). Data of <t>non-biotinylated</t> competitor control were not shown. ( d ) Illustrated is the result of ChIP experiment showing precipitated DNA enriched by Cox-2 antibody or control IgG. qPCR using primers flanking the enhancer suggested a significant enrichment (~7-fold, P =0.034) of the enhancer by Cox-2 antibody, whereas sequence flanking the intronic control region did not show significant enrichment (~3-fold, P =0.062)

    Figure Lengend Snippet: The activities of the Ras–Raf-1–ERK pathway, p38-MAPK, and p46/p54–JNK1 were examined in Tg-DN-Trx1 mice and NTg littermates. ( a ) Some mice were subjected to aortic banding for 2 weeks. Activities of p42/p44–ERK ( a ), Raf-1 ( b ), p38-MAPK ( e ), and p46/p54–JNK1 ( f ) were determined using anti-phosphospecific Ab’s. The same filter was reprobed with respective non-phosphospecific Ab. ( e ) Cell extracts prepared from cardiac myocytes overexpressing mammalian sterile 20–like kinase 1 (Mst1) were used as positive control (P/C). The gel picture is representative of three to ten experiments in each immunoblot analysis. ( c ) The activity of Ras was determined using the Ras-binding domain in Raf-1 coupled with agarose. ( d ) S-thiolation of Ras was determined as described in Methods. COS-7 cells grown in 60-mm dishes were transfected with the indicated expression plasmids (2 μg). Cells were incubated with biotinylated cysteine (0.5 mM), and S-thiolated proteins were isolated by streptavidin-Sepharose. Samples were subjected to immunoblot analyses with anti-Ras Ab. AS-Trx1, antisense Trx1.

    Article Snippet: After washing, biotinylated secondary Ab (anti-mouse IgG; BD Pharmingen) was applied for 1 hour, followed by streptavidin-HRP (BD Pharmingen) for 30 minutes at room temperature.

    Neto1 modulates kainate receptor function in the hippocampus. ( a-c ) Representative examples of inward currents elicited by agonist (3 μM kainate) from Neto1-knockout and wild-type littermate mice recorded in the whole-cell voltage clamp configuration in CA3 pyramidal cells ( a ), CA1 s. radiatum interneurons ( b ), and cerebellar Purkinje cells ( c ). Kainate-evoked inward currents were recorded in the presence of (in μM) 30 GYKI 53655, 50 d-APV, 100 picrotoxin, and 0.5 TTX. Each bar shows the mean peak current amplitude in each neuron from the numbers of cells;animals indicated. ( d ) To compare cell surface expression of KARs, acute hippocampal slices were prepared and biotinylated with cell-impermeable Sulfo-NHS-SS-biotin. After solubilization, biotinylated proteins were precipitated with Neutravidin-beads to isolate proteins at the cell surface. Most GluK2/3 was detected in the “Surface” fraction, whereas a cytosolic protein, tubulin, was detected in the “Internal” fraction. ( e ) No obvious change in surface expression of GluK2/3 or GluK5 was observed in acute hippocampal slices from wild-type and Neto1-knockout mice (n = 6). Scale bars (a-c): 50 μm. Data are given as mean ± s.e.m.; * P

    Article Snippet: Then sections were incubated successively with 10% normal goat serum for 20 min, primary antibodies (1 μg/ml) overnight, biotinylated secondary antibodies for 2 h and avidin-biotin-peroxidase complex for 1 h, using a Histofine SAB-PO(R) kit (Nichirei Corp.).
