β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

Advanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Extracellular proteolytic enzymes produced by human pathogenic Vibrio species

Frontiers in Microbiology, 2013
Bacteria in the genus Vibrio produce extracellular proteolytic enzymes to obtain nutrients via digestion of various protein substrates. However, the enzymes secreted by human pathogenic species have been documented to modulate the bacterial virulence ...

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

Advanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Proteoytic Activity and Swarming Growth of Proteus spp. Isolates.

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2019
Many clinical isolates of proteus spp. (30 isolates of P mirabilis and 30 isolates of P. vulgaris) from patients with urinary tract infections (UTIs) were examined for their ability to produce proteolytic enzymes and their ability to form swarming ...

Subtilases: a major prospect to the genome editing in horticultural crops

Frontiers in Plant Science
Plant peptides, synthesized from larger precursor proteins, often undergo proteolytic cleavage and post-translational modifications to form active peptide hormones. This process involves several proteolytic enzymes (proteases).
