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.

Unravelling the complex influence of dissolved organic matter on microbial diversity in a salinized lake.

Ecosystems in cold and arid regions, such as Dai Lake - a typical inland, salinized lake in the semi-arid region of northern China - face severe environmental challenges, including salinization and biodiversity loss. This study investigates the chemical composition of dissolved organic matter (DOM) and the structure of microbial communities in lake water and sediments, offering novel insights into the ecosystem's dynamics. In winter, DOM in the lake water is primarily derived from decaying plant and animal matter, while sediment DOM is predominantly associated with microbial activity.

Elucidating the effect of chitosan microgel characteristics on the large amplitude oscillatory shear (LAOS) behavior of their stabilized high internal phase emulsions using the sequence of physical processes (SPP) approach and comparison with mayonnaise.

Chitosan microgels (h-CSMs) were prepared by cross-linking hydrophobically modified chitosan with sodium phytate (SP). Emulsions stabilized by h-CSMs with different inter-phase fraction, microgel concentration and cross-linking density were studied of their microstructural and rheological properties. In particular, the large amplitude oscillatory shear (LAOS) of the high internal phase emulsions (HIPEs) stabilized by h-CSMs were systematically analyzed using the Fourier transform with Chebyshev polynomials (FTC) and sequence of physical processes (SPP) methods, to explore their nonlinear rheological properties.

CMCS-PVA@CA hydrogel dressing: A promoter of wound healing with MRSA virulence attenuation function.

Traditional wound dressings, primarily centered on antimicrobial or bactericidal strategies, have inadvertently contributed to the rise of drug-resistant bacterial colonies at wound sites, thus prolonging the healing process. In this study, we developed an innovative hydrogel dressing, CMCS-PVA@CA, incorporating carboxymethyl chitosan (CMCS), polyvinyl alcohol (PVA), and cichoric acid (CA), specifically designed to treat skin wounds infected with methicillin-resistant Staphylococcus aureus (MRSA). Computational biology analyses reveal that CA exerts substantial anti-virulence activity by targeting serine/threonine phosphatase (Stp1), achieving an IC of 3.
