Matrix metalloproteinases (MMPs) are zinc-dependent enzymes crucial for bone and cartilage. Mutations in MMP genes reveal their vital roles in skeletal development and remodeling throughout life.
Area of Science:
- Biochemistry
- Molecular Biology
- Skeletal Biology
Background:
- Matrix metalloproteinases (MMPs) are zinc-dependent proteolytic enzymes.
- Several MMPs are highly expressed in mammalian bone and cartilage.
- These MMPs can cleave native collagens, suggesting collagenase activity in vivo.
Purpose of the Study:
- To review the functions of MMPs in skeletal biology.
- To explore the roles of MMPs in endochondral ossification and bone remodeling.
- To discuss insights gained from genetic mutations in MMPs and collagen.
Main Methods:
- Review of existing literature on MMPs in skeletal tissues.
- Analysis of spontaneous mutations in human MMP genes.
- Examination of targeted mutations in mouse Mmp and collagen genes.
Main Results:
- MMPs play significant roles in embryonic endochondral ossification.
- MMPs are involved in postnatal bone modeling and remodeling.
- Genetic studies in humans and mice have elucidated specific MMP functions.
Conclusions:
- MMPs are essential regulators of skeletal development and maintenance.
- Understanding MMP functions is critical for skeletal health research.
- Further investigation into MMP mechanisms is warranted.

The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...
