| 背景 | Fibulin 5, also known as DANCE and EVEC, is a secreted 55 kDa matricellular glycoprotein that plays an important role in elastic fiber network assembly and angiogenesis (1). Mature human Fibulin 5 contains an N-terminal EGF-like domain with an RGD motif, a 44 amino acid (aa) spacer region, five more tandem EGF-like domains, and a 115 aa Fibulin-like C-terminal region (2, 3). Mature human Fibulin 5 shares 95% aa sequence identity with mouse and rat Fibulin 5. Fibulin 5 is expressed by smooth muscle cells and endothelial cells of the developing vasculature as well as by migrating neural crest cells and lung interstitial fibroblasts (2‑4). It is down‑regulated in the adult vasculature but is re‑expressed at aortic branching points, in the uterus, and at sites of mechanical or atherosclerotic injury (2, 3, 5). The RGD motif of Fibulin 5 binds to several cell surface Integrins including alpha V beta 3, alpha V beta 5, alpha 9 beta 1, alpha 4 beta 1, and alpha 5 beta 1 (2, 6, 7). The calcium-dependent binding of Fibulin 5 to elastic fibers serves to anchor cells to the extracellular matrix (8). Fibulin 5 promotes elastic fiber assembly and maturation by organizing Tropoelastin, LTBP-2, and the crosslinking lysyl oxidase-like enzymes LOXL1, 2, and 4 along Fibrillin microfibrils (6, 9‑11). In aged mice with decreased tissue elasticity, proteolytic removal of the N-terminal EGF-like domain prevents Fibulin 5 from interacting with Fibrillin-1 microfibrils (10). Fibulin 5 functions as an angiogenesis inhibitor by inhibiting vascular smooth muscle proliferation and migration and by limiting vascular sprouting (5, 12). Fibulin 5 is down‑regulated in many malignancies (15). When experimentally re‑expressed, however, Fibulin 5 enhances tumor cell invasiveness and cooperates with TGF-beta in initiating and promoting epithelial-mesenchymal transition (EMT) (13, 15). Defects in Fibulin 5 expression or function can result in a loss of connective tissue integrity, cardiac elasticity, and ability to remodel the vasculature after injury (8, 5, 14). |

Detection of Human Fibulin 5/DANCE by Western Blot. Western blot shows lysates of human heart tissue, human lung tissue, and human brain (cerebellum) tissue. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Fibulin 5/DANCE Monoclonal Antibody (Catalog # MAB3095) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, Recombinant Human Fibulin 5 (Catalog # 3095‑FB) (5 ng/lane) was included. A specific band was detected for Fibulin 5/DANCE at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. |
