The Function and Roles of ADAMTS-7 in Inflammatory Diseases

الملخص EN

The ADAMTS proteinases are a group of multidomain and secreted metalloproteinases containing the thrombospondin motifs.

ADAMTS-7 is a member of ADAMTS family and plays a crucial role in the pathogenesis of arthritis.

Overexpression of ADAMTS-7 gene promotes the breakdown of cartilage oligomeric matrix protein (COMP) matrix and accelerates the progression of both surgically induced osteoarthritis and collagen-induced arthritis.

Moreover, ADAMTS-7 and tumor necrosis factor-α (TNF-α) form a positive feedback loop in osteoarthritis.

More significantly, granulin-epithelin precursor, a growth factor has important roles in bone development and bone-associated diseases, disturbs the interaction between ADAMTS-7 and COMP, and prevents COMP degradation.

This review is based on our results and provides an overview of current knowledge of ADAMTS-7, including its structure, function, gene regulation, and inflammatory diseases involvement.
