Supplementary information

The proteins MMP1 MMP9 and MMP13 belong to the matrix metalloproteinase (MMP) family and function mainly as enzymes that degrade various components of the extracellular matrix. MMP1 also known as collagenase-1 has a mass of approximately 54 kDa and primarily targets interstitial collagen. MMP9 known as gelatinase B is about 92 kDa and digests denatured collagen (gelatin) and elastin. MMP13 or collagenase-3 is around 60 kDa and degrades type II collagen among other substrates. These MMPs express in various tissues including skin cartilage and the immune system playing roles in tissue remodeling and repair.

Biological function summary

These MMPs regulate extracellular matrix composition and influence cellular behaviors like migration and invasion. MMP1 MMP9 and MMP13 participate in normal developmental processes and the breakdown of extracellular matrix in pathological conditions. They form complexes with tissue inhibitors of metalloproteinases (TIMPs) that modulate their activities ensuring balanced matrix turnover. Their expression requires precise control because unregulated activity can lead to tissue damage.

Pathways

MMP1 MMP9 and MMP13 integrate into complex networks like the collagen degradation and inflammation pathways. MMP9 is an important actor in the inflammatory response often upregulated by cytokines and serving a role in leukocyte migration facilitated by its interaction with integrins. The Wnt signaling pathway connects to MMP13 highlighting its involvement in cartilage metabolism and bone remodeling. These proteins interact with others in these pathways like interleukins and integrins to coordinate a broad range of physiological effects.

MMP dysregulation associates with conditions like arthritis and cancer. In arthritis MMP13 excessively degrades cartilage collagen contributing to joint destruction while interactions with cytokines amplify inflammation. In cancer MMP9 assists tumor invasion and metastasis through matrix degradation and works in conjunction with VEGF to promote angiogenesis. MMP9 inhibitors have been investigated for therapeutic use in cancer treatment due to these contributions. Understanding these mechanisms highlights the importance of MMP regulation and inhibition in disease contexts.
