The structure and function of cartilage proteoglycans [PDF]

European Cells & Materials, 2006
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

Knockdown of asporin affects transforming growth factor-β1-induced matrix synthesis in human intervertebral annulus cells

Journal of Orthopaedic Translation, 2016
Background/Objective: Asporin is associated with osteoarthritis and lumbar disk degeneration. Previous studies in chondrocytes showed that asporin can bind to transforming growth factor-β1 (TGF-β1) and downregulate matrix biosynthesis.

Ammonia Accumulation Drives Intervertebral Disc Degeneration by Triggering Ammonia‐Induced Cell Death Through Lysosome–Mitochondria Crosstalk

Cell Proliferation, EarlyView.
Mechanical strain disrupts the lysosome‐mitochondria axis via GLS1‐mediated ammonia toxicity, causing NP cell death and ECM breakdown in IVDD. CB839‐mediated GLS1 inhibition effectively rescues cellular homeostasis and alleviates disc degeneration.

Synovial fluid level of aggrecan ARGS fragments is a more sensitive marker of joint disease than glycosaminoglycan or aggrecan levels: a cross-sectional study [PDF]

, 2009
Introduction Aggrecanase cleavage at the (392)Glu-(393)Ala bond in the interglobular domain (IGD) of aggrecan, releasing N-terminal (393)ARGS fragments, is an early key event in arthritis and joint injuries.

Sclerostin regulates bone morphogenetic protein (BMP) bioavailability through interactions with BMP complexes and fibrillin microfibrils

The FEBS Journal, EarlyView.
Sclerostin (SOST) is a multifunctional extracellular modulator of BMP and Wnt signaling. SOST binds with high affinity to fibrillin‐1 and fibrillin‐2, localizing it to fibrillin microfibrils and regulating its extracellular bioavailability. Fibrillin‐bound SOST cannot engage BMP‐7 prodomain (PD) complexes, revealing a competitive mechanism that ...

Eccentric Occlusal Loads Remodel the Dentoalveolar and Temporomandibular Biomechanical Unit in Rats

Journal of Oral Rehabilitation, EarlyView.
Eccentric occlusal loads remodel the dentoalveolar and temporomandibular joints in the masticatory biomechanical unit in rats. (A) Bite block as an occlusal rise (OR) on the rat maxillary first molar (green region) is shown. (B) 18F‐NaF Positron emission tomography localised regions of higher metabolic activity (higher uptake in the left condyle ...

Understanding exosomes in regenerative dentistry

Periodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...
