Spatially Resolved Metabolomics of Optimal Cutting Temperature (OCT) Compound‐Embedded Tumors
ABSTRACT Mass spectrometry imaging (MSI) is emerging as a powerful tool for uncovering the distribution of metabolites in the tumor microenvironment and studying tumor metabolism in vivo. To date, MSI of biobanked tissues contextualized by patient data has been limited to peptides, proteins, and glycans—with few examples for metabolites.

ABSTRACT We previously developed nanobodies acting as positive allosteric modulators (PAMs) of the calcium‐sensing receptor (CaSR). Here, we sought to develop more potent CaSR modulators by creating bivalent nanobody constructs using ‘tail‐to‐head’ peptide‐linker conjugation.

Engineering Stable Lentiviral Vector Producer Cells Improves LVV Production
ABSTRACT Stable lentiviral vector producer cell lines represent a promising platform for scalable and cost‐efficient vector manufacturing, yet their productivity is often limited by intrinsic host‐cell constraints. In this study, we aimed to identify cellular factors restricting LVV production in stable doxycycline‐inducible GPRTG producer cell lines ...

Spermine Stimulates The Threonyl-trna Formation In Rat Liver.
The effects of spermine have been studied on the aminoacylation reaction catalyzed by rat liver threonyl-tRNA synthetase. Spermine can not replace Mg2+ in this reaction.

Effect of DFMO and spermine supplementation on Active Rap-1 protein levels.
Neither DFMO nor spermine activated Rap-1. negative control: cell lysate treated with GDP. positive control: cell lysate treated with GTP-gamma-S. no treatment: cell lysate with no treatment. DFMO: lysate of cells cultured with 3 mM DMFO.

The effect of spermine on the initiation of mitochondrial protein synthesis [PDF]
Polyamines are important in both prokaryotic and eukaryotic translational systems. Spermine is a quaternary aliphatic amine that is cationic under physiological conditions.

Efferocytosis is a key process for macrophages to clear apoptotic cells, which undergoes the “ Find Me” chemotaxis signal stage, the “eat me” phagocytosis recognition stage and the “digest me” digestion stage in turn. During the aforementioned three stages, various signaling molecules released by apoptotic cells can promote the phenotypic polarization ...

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