Extracellular matrix components and general hyaluronan-binding proteins (ECM/HABPs)

Extracellular matrix (ECM) components and general hyaluronan-binding proteins (HABPs), collectively known as hyaladherins, represent a broad functional group of molecules essential for tissue architecture and cellular signaling (Source: PubMed PMID: 15121010). This group encompasses structural proteins like collagen and laminin, as well as specialized proteins that interact specifically with the glycosaminoglycan hyaluronan, such as the cell-surface receptor CD44 and the secreted proteoglycan versican (Source: UniProt P16070, P13611). These molecules regulate critical biological processes including cell adhesion, migration, and proliferation by acting as both physical scaffolds and ligands for signal transduction (Source: Nature Reviews Molecular Cell Biology, 2014). In pathological contexts, particularly in solid tumors and chronic inflammatory diseases, the dysregulation of ECM components and HABPs facilitates tissue remodeling, tumor invasion, and immune evasion (Source: PubMed PMID: 24388214). Therapeutic interventions targeting this group include hyaluronidases, such as vorhyaluronidase alfa, which are used to degrade the HA-rich matrix to improve the interstitial transport of co-administered drugs (Source: FDA Label for Hylenex). However, targeting these components is associated with significant challenges, including the risk of disrupting normal tissue homeostasis and causing musculoskeletal toxicity (Source: ClinicalTrials.gov NCT02715804).
