Engineering tunable biosensors for monitoring putrescine in Escherichia coli [PDF]

, 2018
Biosensors can be a powerful tool for real-time monitoring of specific small molecules and for precise control of gene expression in biological systems. Thus, biosensors have attracted much attention for monitoring increasing number of molecules. However,

Revisiting small‐molecule fluorescent probes in food freshness detection

Smart Molecules, EarlyView.
Fluorescent probes serve as versatile tools for food freshness monitoring. This review summarizes recent advances in probes targeting biogenic amines, hydrogen sulfide, pH values, and other key spoilage markers, highlighting their design principles, sensing mechanisms, and practical applications in food quality monitoring. Abstract Food spoilage driven

MTAP Deficiency as a Metabolic Vulnerability in Cancer: Implications for Synthetic Lethal Therapy

Cancer Science, EarlyView.
MTAP deletion creates a therapeutically actionable metabolic vulnerability through MTA accumulation and PRMT5 dependency. This review summarizes the biochemical basis of MTAP‐directed synthetic lethality, emerging PRMT5/MAT2A inhibitors, clinicogenomic features of MTAP‐deleted tumors, and future strategies for precision oncology.

Inhibition of Ornithine Decarboxylase 1 Mitigates Denervation‐Induced Muscle Atrophy by Suppressing Proteolysis and Preserving Muscle Stem Cell Homeostasis

Cell Proliferation, EarlyView.
Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis

Immunology, EarlyView.
Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...

Physicochemical Quality and Chemical Safety of Commercial Wet Cat Food: Composition, Oxidation, Biogenic Amines, and Trace Elements

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study investigated the physicochemical characteristics and chemical safety of commercial wet cat foods marketed in Brazil. Twenty products labeled as beef, chicken and fish flavors were analyzed for proximate composition, pH, lipid and protein oxidation, biogenic amines, and essential and potentially toxic trace elements.
