Detection of VAP-1/AOC3 by Western Blot

Detection of VAP-1/AOC3 by Western Blot

Biophysical and functional characterization of endometrial pericytes and EnSCs. (A) Immunohistochemistry showing VAP-1 expression in luteal-phase human endometrium, hematoxylin was used to stain the nuclei. Staining indicates VAP-1 reactivity in the vasculature and spiral arteries, arrow pointing to spiral artery. Scale bar: 200 μm. (B) VAP-1 expression was determined at protein level in freshly isolated SUSD2+ pericytes and SUSD2− EnSCs from three independent endometrial biopsies by Western blot analysis and normalized to beta -actin and relative intensity determined by densitometry; Student's t-test; *P < 0.05. (C) Expression of ELN (left panel), CNN1 (middle panel) and MYH11 (right panel) transcripts was determined by RT-qPCR in freshly isolated SUSD2+ pericytes and SUSD2− EnSCs from four independent endometrial biopsies; Student's t-test; *P < 0.05; **P < 0.01. (D) Representative graphs showing proliferation and migration SUSD2+ pericytes and SUSD2− EnSCs monitored in real-time using the xCELLigence system for the indicated time-points. (E) freshly isolated SUSD2+ pericytes and SUSD2− EnSCs were embedded into collagen at a density of 1 × 106 cells per gel. Single cell contraction force was measured using the depth-sensing nanoindentation system. Data represent mean ± SEM of four biological repeat experiments. Student's t-test; **P < 0.01; ****P < 0.0001. Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/33537312), licensed under a CC-BY license.

Background: VAP-1/AOC3

Vascular adhesion protein-1 (VAP-1), also called AOC3 (amine oxidase copper-containing 3) or SSAO (semicarbazide-sensitive amine oxidase), is a copper amine oxidase with a topaquinone cofactor. VAP-1 is a Type II integral membrane protein, but a soluble form of the enzyme is present in human serum, and its level increases in diabetes and some inflammatory liver diseases (1, 2). Human and mouse VAP-1 share 83% amino acid sequence identity. VAP-1 catalyzes the oxidative deamination of small primary amines such as methylamine, benzylamine, and aminoacetone in a reaction that produces an aldehyde, ammonia, and H2O2 (3). The enzyme is sensitive to inhibition by semicarbazide. VAP-1 expression is highest in the endothelium of lung, heart, and intestine, but low in tissues such as brain, spleen, kidney, and liver (4). VAP-1 vascular expression is regulated at sites of inflammation through its release from intracellular granules in which the protein is stored (5). The adhesive function of VAP-1 has been demonstrated in studies showing that the protein is important for the adherence of certain lymphocyte subtypes to inflamed endothelial tissues (6). VAP-1 mediated adhesion is involved in the process of leukocyte extravasation, an important feature of inflammatory responses. The role of VAP-1 amine oxidase activity in this process is not fully defined, but it appears to be carbohydrate-dependent (7). VAP-1 is considered to be a therapeutic target for diabetes, oxidative stress, and inflammatory diseases (8).

    The Antibody worked great in a Positive control (Human Lung) but no reactivity to the equine protein was possible.
