Cross-Dysregulation of O-GlcNAcylation and PI3K/AKT/mTOR Axis in Human Chronic Diseases
The hexosamine biosynthetic pathway (HBP) and the phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) signaling pathway are considered as nutrient sensors that regulate several essential biological processes.

Disruption of the MreB Elongasome Is Overcome by Mutations in the Tricarboxylic Acid Cycle
The bacterial actin homolog, MreB, is highly conserved among rod-shaped bacteria and essential for growth under normal growth conditions. MreB directs the localization of cell wall synthesis and loss of MreB results in round cells and death.

Stimulation of steroid glucuronidation by uridine diphosphate N-acetylglucosamine and by microsomal disruption [PDF]
Glucuronidation of oestrone and of oestradiol in microsomal fractions was markedly and significantly stimulated by UDP-N-acetylglucosamine and by ultrasonication: Triton X-100 also stimulated. This is consistent with compartmentation of UDP-glucuronyl-transferase. Stimulation by UDP-N-acetylglucosamine may be physiologically significant.

Characterization of Yeast Yea4p, a Uridine Diphosphate-N-acetylglucosamine Transporter Localized in the Endoplasmic Reticulum and Required for Chitin Synthesis [PDF]
Chitin is an essential cell wall component, synthesis of which is regulated throughout the cell cycle in the yeast Saccharomyces cerevisiae. We cloned an S. cerevisiae gene, YEA4, whose product is homologous to the Kluyveromyces lactis uridine diphosphate-N-acetylglucosamine (UDP-GlcNAc) transporter.

Background: Polymyxins are a last-line class of antibiotics against multidrug-resistant Acinetobacter baumannii. However, polymyxin resistance can emerge with monotherapy, highlighting the need for synergistic combination therapies.

Regulatory mechanism of O-linked N-acetylglucosamine protein modification on autophagy in cancer. [PDF]
O‐GlcNAcylation serves as a nutrient and stress sensor that dynamically regulates autophagy at multiple stages in cancer cells. It fine‐tunes autophagy initiation, maturation and fusion by modifying key proteins such as ULK1, ATG4B and SNAP‐29. Context‐dependent O‐GlcNAcylation promotes tumour adaptation and therapy resistance via autophagy remodelling.

PolyGlcNAc-containing exopolymers enable surface penetration by non-motile Enterococcus faecalis.
Bacterial pathogens have evolved strategies that enable them to invade tissues and spread within the host. Enterococcus faecalis is a leading cause of local and disseminated multidrug-resistant hospital infections, but the molecular mechanisms used by ...
