Background

Laminin, the most abundant structural and biologically active component in basement membranes, is a complex extracellular glycoprotein with high molecular weight (900 kDa). Laminin is composed of a laminin alpha (400 kDa), beta (215 kDa) and gamma chain (205 kDa), whose multidomain proteins are encoded by distinct genes (LAMA, LAMB, LAMC respectively) and have several isoforms of each chain. The biological functions of the different chains and trimer molecules are largely unknown, but some of the chains have been shown to differ with respect to their tissue distribution, reflecting diverse functions in vivo. Laminin is thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components.

Laminins are an important and biologically active part of the basal lamina, influencing cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis, where anti-laminin antibodies can be widely used to label blood vessels and basement membranes (1). Significant quantities of laminin are found in basement membranes, the thin extracellular matrices that surround epithelial tissue, nerve, fat cells and smooth, striated and cardiac muscle. Excessive serum laminin levels have been associated with fibrosis, cirrhosis and hepatitis, serious and frequent complications of chronic active liver disease characterized by excessive deposition of various normal components of connective tissue in liver (2). Epithelial mesenchymal transition (EMT) biomarkers include fibronectin, laminin, N-cadherin, and Slug (3).
