It is composed of many molecules, including proteins, glycoproteins, proteoglycans, and polysaccharides (1,2). One of the major proteins that comprise the ECM, and the human body, is collagen. Collagens are a large family of proteins. They are trimeric molecules composed of three alpha polypeptide chains that form a triple helix structure that is characteristic of all collagens (3). The large family of collagens is divided into three subgroups: the fibrillar collagens, the non-fibril forming collagens, and the fibril-associated collagens. These subgroups differ in their structure and supramolecular assembly (3). Collagen11A1 (COL11A1) is a minor fibrillar collagen that is not normally expressed at high levels in most normal tissues with the exception of cartilage, where it is expressed in high levels, and some other tissues\/ organs, where it is expressed at a lower level (4). However, it has been reported that the expression of this molecule is correlated with advanced tumorigenic disease through meta analysis of data from multiple cancers, including ovarian, colon, breast, and lung (5). Additionally, it has also been associated with epithelial-mesenchymal transition (EMT) and metastasis (6,7). Cancer associated fibroblasts (CAFs) are typically the most abundant cell type in the stroma of many solid tumors. They are thought to contribute to ECM stiffness, which is ultimately thought to contribute to tumor growth and resistance to chemotherapeutic intervention. COL11A1 has been found to be elevated in CAFs and may contribute to chemotherapy resistance (8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCO11A1; COBA1; COL11A1; COLL6; Collagen alpha-1(XI) chain; collagen type XI alpha 1 chain; collagen XI, alpha-1 polypeptide; collagen, type XI, alpha 1; deafness, autosomal dominant 37; DFNA37; STL2\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800536141993,"sku":"80960S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-80960s","provider":"Iright","version":"1.0","type":"link"}
