3D In Vitro Models of Breast Cancer: Current Challenges and Future Prospects Toward Recapitulating the Microenvironment and Mimicking Key Processes

open access: yesAdvanced Biology, EarlyView.
In vitro cancer models are advantageous for studying important processes such as tumorigenesis, cancer growth, invasion, and metastasis. The complexity and biological relevance increase depending on the model structure, organization, and composition of materials and cells.

ADAMTS proteinases: a multi-domain, multi-functional family with roles in extracellular matrix turnover and arthritis [PDF]

open access: yes, 2005
Members of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) family are known to influence development, angiogenesis, coagulation and progression of arthritis.

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations

open access: yesAdvanced Functional Materials, EarlyView.
Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and

The influence of heavy physical effort on proteolytic adaptations in skeletal and heart muscle and aorta in rats

open access: yesAnnals of Agricultural and Environmental Medicine, 2018
Physical effort can elicit differential adaptive changes in the tissues of trained versus untrained rats. Proteolytic activity in the extracellular matrix could be engaged in such adaptation due to its influence on the elasticity of tissues. The effects

Non-canonical proteolytic activation of human prothrombin by subtilisin from Bacillus subtilis may shift the procoagulant\ue2\u80\u93anticoagulant equilibrium toward thrombosis [PDF]

open access: yes, 2017
Blood coagulation is a finely regulated physiological process culminating with the factor Xa (FXa)-mediated conversion of the prothrombin (ProT) zymogen to active -thrombin (T).

Proteolytic Enzymes in Entamoeba histolytica [PDF]

open access: yesNature, 1956
THE presence of proteolytic enzymes in Entamoeba histolytica has been suspected for many years and the extracellular secretion of these enzymes has been put forward by many authors as an explanation of the mechanism of tissue invasion by this parasite1. Experimental evidence of their occurrence in E.

Production of Proteolytic Enzymes by a Keratin-Degrading Aspergillus niger

open access: yesEnzyme Research, 2011
A fungal isolate with capability to grow in keratinous substrate as only source of carbon and nitrogen was identified as Aspergillus niger using the sequencing of the ITS region of the rDNA.

Adalimumab‐Poloxamer Conjugate for Bio‐Better: Enhanced Stability and Function

open access: yesAdvanced Functional Materials, EarlyView.
Antibody‐polymer conjugates, particularly poloxamer conjugates, enhance antibody stability by improving tolerance to physicochemical stress and attenuating proteolysis by proteases. Furthermore, the higher affinity observed with poloxamer conjugation compared to standard PEGylation results in improved therapeutic efficacy in rheumatoid arthritis mouse ...
