Published: August 2016

Proteases play a key role in tumor biology, with high expression levels often correlating with poor prognosis for cancer patients - making them excellent disease markers for tumor diagnosis. Despite their significance, quantifying proteolytic activity in vivo remains a challenge. Nanoparticles, with their ability to serve as scaffolds having unique chemical, optical and magnetic properties, offer the promise of merging diagnostic medicine with material engineering. Such nanoparticles can interact preferentially with proteases enriched in tumors, providing the ability to assess disease state in a noninvasive and spatiotemporal manner. We review recent advances in the development of nanoparticles for imaging and quantification of proteolytic activity in tumor models, and prognosticate future advancements.

December 2024

Department of Food Hygiene and Technology, Faculty of Veterinary Medicine, University of Belgrade, Bulevar oslobodjenja 18, 11000 Belgrade, Serbia.

Owing to the rich diversity of lactic acid bacteria (LAB) microbiota, traditional Serbian white-brined cheeses can serve as a valuable source of LAB strains with promising technological and functional properties. This study aimed to identify potential candidates for developing commercial bacterial cultures, which could be used to produce cheese with distinct sensory qualities and added value as a functional food product. A total of 83 LAB isolates were tested for their ability to grow under different salt concentrations and temperatures; their acidifying, proteolytic, and lipolytic activities; and their production of diacetyl and exopolysaccharides (EPSs).

Influenza is a worldwide health problem that causes significant morbidity and mortality among the elderly; therefore, its prevention is important. During influenza virus infection, the cleavage of hemagglutinin (HA) is essential for the virus to enter host cells. Influenza virus-bacteria interactions influence the pathogenicity of infections, and specific bacteria contribute to the severity of the disease by participating in HA cleavage.

Cabozantinib Selectively Induces Proteasomal Degradation of p53 Somatic Mutant Y220C and Impedes Tumor Growth.

Inactivation of p53 by mutations commonly occurs in human cancer. The mutated p53 proteins may escape proteolytic degradation and exhibit high expression in tumors, and acquire gain-of-function activity that promotes tumor progression and chemo-resistance. Therefore, selectively targeting of the gain-of-function p53 mutants may serve as a promising therapeutic strategy for cancer prevention and treatment.
