ADAMTS -1 and -4 are up-regulated following transient middle cerebral artery occlusion in the rat and their expression is modulated by TNF in cultured astrocytes [PDF]

open access: yes, 2006
ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) enzymes are a recently described group of metalloproteinases. The substrates degraded by ADAMTS-1, -4 and -5 suggests that they play a role in turnover of extracellular matrix in the

Microengineered Gradient Hydrogels for Mechanobiology

open access: yesAdvanced Healthcare Materials, EarlyView.
Gradient hydrogels are used to mimic the mechanical heterogeneity in native tissues, offering powerful in vitro platforms to study cell‐material interactions in diverse pathophysiological contexts. Here, we present a comprehensive review of the design and experimental considerations for stiffness gradient hydrogels, discussing exemplary achievements ...

Pathophysiology of matrix metalloproteinases in breast cancer progression

open access: yesJournal of Clinical and Scientific Research, 2019
Matrix metalloproteinases (MMPs) are secretary or membrane type proteolytic enzymes that act on extracellular matrix protein components such as collagens, gelatins, elastins, laminins, fibronectins, and integrins. MMPs are synthesized as zymogens and are

Inhibition of interleukin-1β-stimulated collagenase and stromelysin expression in human tendon fibroblasts by epigallocatechin gallate ester [PDF]

open access: yes, 2004
The medicinal benefits of green tea (Camellia sinensis) consumption have been attributed to bioavailable polyphenols, notably epigallocatechin gallate (EGCG).

Recapitulating Endochondral Ossification for Bone Repair: From Development to Engineering Strategy

open access: yesAdvanced Healthcare Materials, EarlyView.
This review summarizes the developmental basis of endochondral ossification (ECO) and its applications in bone tissue engineering (BTE). It first outlines the key biological processes and signaling pathways underlying ECO, then discusses biomaterial‐based engineering strategies derived from these principles, and finally highlights future directions for

Are matrix metalloproteinases the missing link?

open access: yesInvertebrate Survival Journal, 2005
It is more and more evident that the matrix metalloproteinase (MMP) system is not a characteristic feature of vertebrate animals only, as it can also be found in many invertebrate organisms.

The role of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) in the development of esophageal cancer

open access: yesFolia Histochemica et Cytobiologica, 2012
Esophageal cancer (EC) is one of the most aggressive malignant tumors of the gastrointestinal tract. There are two distinct histological types of EC: esophageal squamous cell carcinoma and adenocarcinoma of the esophagus.

MMP-2 and MMP-9 in normal mucosa are independently associated with outcome of colorectal cancer patients. [PDF]

open access: yes, 2012
BackgroundUpregulation of the matrix metalloproteinases MMP-2 and MMP-9 in various cancers has been associated with worse survival of the patients.MethodsWe assessed MMP-2 and MMP-9 levels in normal colorectal mucosa from colorectal cancer patients in ...

Matrix Viscoelasticity Regulates Dendritic Cell Migration and Immune Priming

open access: yesAdvanced Materials, EarlyView.
Matrix viscoelasticity is a key mechanical feature of the tumor microenvironment but remains poorly understood in immune regulation. Here, we develop a tunable collagen platform to decouple viscoelasticity from stiffness and show that slow‐relaxing matrices constrain dendritic cell migration by limiting actomyosin‐driven matrix remodeling, thereby ...

TET1 Suppresses Cancer Invasion by Activating the Tissue Inhibitors of Metalloproteinases

open access: yesCell Reports, 2012
Tumor suppressor gene silencing through cytosine methylation contributes to cancer formation. Whether DNA demethylation enzymes counteract this oncogenic effect is unknown.
