: In healthy cartilage, chondrocytes maintain an expression of collagens and proteoglycans and are sensitive to growth factors and cytokines that either enhance or reduce type II collagen synthesis. In osteoarthritis, pro-inflammatory cytokines, such as

Light‐Inducible Activation of FGFR3 Facilitates Chondrocyte Maturation
Light‐inducible activation of FGFR3 induced robust activation of MAPK signaling, promoting proliferation and collagen depositon in induced chondrocytes and prevent the degeneration of osteoarthritic chondrocytes.

Irreversible ECM proteolysis by remodeling enzymes shapes development, homeostasis, and disease. ECM‐degrading proteases display cell specificity and are governed by shared mechanisms, exhibiting functional redundancy in generating matrikines, growth factors, and cytokines.

A guide to the types, structures, and multifaceted functions of matrix metalloproteinases in cancer
Matrix metalloproteinases (MMPs) orchestrate cancer progression and metastasis through proteolytic and non‐proteolytic actions. By remodeling the tumor microenvironment, enhancing growth factor availability, and modulating cell behavior, MMPs promote proliferation, migration or invasion, and epithelial‐to‐mesenchymal transition. Alongside extracellular

The structure and function of cartilage proteoglycans [PDF]
Cartilage contains a variety of proteoglycans that are essential for its normal function. These include aggrecan, decorin, biglycan, fibromodulin and lumican. Each proteoglycan serves several functions that are determined by both its core protein and its

Osteoarthritis (OA) is a major public health concern for which a reliable non-invasive treatment option has yet to be developed. In the present study, we investigated the effects of saxagliptin, a novel dipeptidyl peptidase IV (DPP-4) inhibitor, on ...

Small leucine‐rich proteoglycans (SLRPs) are key modulators of extracellular matrix structure and signaling. Their proteolytic processing by MMPs (Matrix Metalloproteinases), ADAMTS (disintegrin and metalloprotease with thrombospondin motifs), and serine proteases generates bioactive fragments that regulate collagen remodeling, inflammation, and ...

Chondrogenic potential of human articular chondrocytes and skeletal stem cells: a comparative study
Regenerative medicine strategies have increasingly focused on skeletal stem cells (SSCs), in response to concerns such as donor site morbidity, dedifferentiation and limited lifespan associated with the use of articular chondrocytes for cartilage repair.

Degradomics for large‐scale mechanistic insights on proteases and proteolysis in human health
Proteolysis has an important role in human disease but remains relatively unexplored. Degradomics, the uncovering of proteolysis in tissues, cells, and proteins, uses mass spectrometry‐based terminomics to identify protein termini occurring therein (forward degradomics) and to define the actions of proteases (reverse degradomics).
