Ligand interaction landscape of transcription factors and essential enzymes in E. coli.

Knowledge of protein-metabolite interactions can enhance mechanistic understanding and chemical probing of biochemical processes, but the discovery of endogenous ligands remains challenging. Here, we combined rapid affinity purification with precision mass spectrometry and high-resolution molecular docking to precisely map the physical associations of 296 chemically diverse small-molecule metabolite ligands with 69 distinct essential enzymes and 45 transcription factors in the gram-negative bacterium Escherichia coli. We then conducted systematic metabolic pathway integration, pan-microbial evolutionary projections, and independent in-depth biophysical characterization experiments to define the functional significance of ligand interfaces.

The Sublingua of and : Only a Cleaning Function?

The sublingua is an anatomical structure located under the tongue. This rare organ can be present in some animals as a rudimentary structure, but among prosimian primates, such as lemurs and lorises, it is fully developed. In addition to the sublingua, prosimians have modified lower incisors and canines called "dental comb".

: Precise Proteomics Technology for Mapping Receptor Protein Neighborhoods at the Cancer Cell Surface.

Cell surface receptors are pivotal to cancer cell transformation, disease progression, metastasis, early detection, targeted therapy, drug responses, and clinical outcomes. Since they coordinate complex signaling communication networks in the tumor microenvironment, mapping the physical interaction partners of cell surface receptors in vivo is vital for understanding their roles, functional states, and suitability as therapeutic targets. Yet traditional methods like immunoprecipitation and affinity purification-mass spectrometry often fail to detect key but weak or transient receptor-protein interactions.

Adults with RDs and parents/caregivers to children with RDs (N = 1128) completed open-ended survey items. Responses were analyzed using thematic analysis.

Peripheral Blood DNA Methylation Changes in Response to Treatment in Aged Mice.

Alterations in epigenetic modifications, like DNA methylation, in peripheral blood could serve as a useful, minimally invasive biomarker of the effects of anti-aging interventions. This study explores this potential with a water extract of the botanical (CAW). Eighteen-month-old mice were treated with CAW in their drinking water for 5 weeks alongside vehicle-treated eighteen-month-old C57BL6 mice.

Natural killer cells occupy unique spatial neighborhoods in HER2 and HER2 human breast cancers.

Tumor-infiltrating lymphocytes are considered clinically beneficial in breast cancer, but the significance of natural killer (NK) cells is less well characterized. As increasing evidence has demonstrated that the spatial organization of immune cells in tumor microenvironments is a significant parameter for impacting disease progression as well as therapeutic responses, an improved understanding of tumor-infiltrating NK cells and their location within tumor contextures is needed to improve the design of effective NK cell-based therapies. In this study, we developed a multiplex immunohistochemistry (mIHC) antibody panel designed to quantitatively interrogate leukocyte lineages, focusing on NK cells and their phenotypes, in two independent breast cancer patient cohorts (n = 26 and n = 30).

Synthesis of -Aryl Carbamates from Aryl(TMP)iodonium Salts via C-N Coupling.

Modular C-N coupling is a desirable way to construct -aryl carbamates, which are privileged scaffolds in active pharmaceutical ingredients. However, there are no broadly applicable metal-free methods for the-arylation of carbamates. Herein, we describe a metal-free approach that uses aryl(TMP)iodonium salts as arylation reagents for cyclic carbamates by exploiting the metal-like reactivity of iodine(III).
