Modulation of Animal Gut Health by Milk Oligosaccharide

Animal Research and One Health, EarlyView.
This review summarizes the composition and structural characteristics of MOs across different mammalian species, and elucidates their roles and mechanisms in maintaining intestinal homeostasis by regulating gut microbiome and enhancing intestinal chemical, physical and immune barriers.

Antioxidant Functions of the Aryl Hydrocarbon Receptor [PDF]

Stem Cells International, 2016
The aryl hydrocarbon receptor (AhR) is a transcription factor belonging to the basic helix‐loop‐helix/PER‐ARNT‐SIM family. It is activated by a variety of ligands, such as environmental contaminants like polycyclic aromatic hydrocarbons or dioxins, but also by naturally occurring compounds and endogenous ligands.

Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

Biological Reviews, EarlyView.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

The Asymmetric Self‐Replicative Alkylation of N‐Arylaldimines Using Organolithium Reagents

Chemistry – A European Journal, EarlyView.
Here, we report a new asymmetric autoinductive reaction; the addition of nBuLi to N‐arylaldimines to form chiral lithium amides. The reaction proceeds with full conversion and complete transfer of chirality, representing the first example of an asymmetric autoinductive reaction with organolithium reagents.

Checkpoint Receptor TIGIT Expressed on Tim-1+ B Cells Regulates Tissue Inflammation

Cell Reports, 2020
Summary: Tim-1, a phosphatidylserine receptor expressed on B cells, induces interleukin 10 (IL-10) production by sensing apoptotic cells. Here we show that mice with B cell-specific Tim-1 deletion develop tissue inflammation in multiple organs including ...

Polychlorinated naphthalenes in the serum of individuals with thyroid dysfunction and their potential mechanisms of impact on disease progression

Emerging Contaminants
Polychlorinated naphthalenes (PCNs) comprise 75 congeners, with varying concentrations and major congeners across different populations. Recent studies have found a relationship between PCNs and thyroid hormone levels, suggesting they may interfere with ...

Fecal Microbiota Transplantation and Microbiota‐Based Therapeutics in Allogeneic Hematopoietic Stem Cell Transplantation: Current Evidence and Future Directions

Clinical Pharmacology &Therapeutics, EarlyView.
The intestinal microbiome is a key regulator of immune homeostasis, metabolism, and epithelial barrier integrity. In patients with malignant hematological diseases, particularly those undergoing hematopoietic stem cell transplantation, microbiome perturbations by reduced diversity, pathobiont expansion, and loss of beneficial metabolites are common as ...
