Cold Orthogonal Translation: A Psychrophilic Pyrrolysyl‐tRNA Synthetase Boosts Genetic Code Expansion in E. coli

open access: yesAdvanced Science, EarlyView.
ABSTRACT Orthogonal translation systems (OTSs) enable site‐specific incorporation of non‐canonical amino acids (ncAAs) and are central to genetic code expansion. Current engineering strategies typically rely on hyperstable aminoacyl tRNA synthetase (aaRS) scaffolds to tolerate destabilizing mutations required for substrate diversification.

Production of Glycopeptide Derivatives for Exploring Substrate Specificity of Human OGA Toward Sugar Moiety. [PDF]

open access: yes, 2018
O-GlcNAcase (OGA) is the only enzyme responsible for removing N-acetyl glucosamine (GlcNAc) attached to serine and threonine residues on proteins. This enzyme plays a key role in O-GlcNAc metabolism.

The roles of OGT and its mechanisms in cancer

open access: yesCell & Bioscience
AbstractO-linked-N-acetylglucosaminylation (O-GlcNAcylation) is a common and important post-translational modification (PTM) linking O-linked β-N-acetylglucosamine (O-GlcNAc) to serine and threonine residues in proteins. Extensive research indicates its impact on target protein stability, activity, and interactions.

O‐GlcNAcylated TAP1 Impairs Antigen Presentation and Promotes Immune Evasion in Bladder Cancer

open access: yesAdvanced Science, EarlyView.
This article unveils a critical mechanism of immune evasion in bladder cancer, which the O‐GlcNAc modification of TAP1 disrupts antigen presentation. This modification triggers HLA‐A degradation, shielding tumor cells from CD8+ T cell attack. The findings highlight targeting this pathway as a promising therapeutic avenue to sensitize tumors to ...

5mC-hydroxylase activity is influenced by the PARylation of TET1 enzyme [PDF]

open access: yes, 2015
5-hydroxymethylcytosine is a new epigenetic modification deriving from the oxidation of 5-methylcytosine by the TET hydroxylase enzymes. DNA hydroxymethylation drives DNA demethylation events and is involved in the control of gene expression ...

Accelerating Primary Screening of USP8 Inhibitors from Drug Repurposing Databases with Tree‐Based Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
This study introduces a tree‐based machine learning approach to accelerate USP8 inhibitor discovery. The best‐performing model identified 100 high‐confidence repurposable compounds, half already approved or in clinical trials, and uncovered novel scaffolds not previously studied. These findings offer a solid foundation for rapid experimental follow‐up,

Expression of O-GlcNAc transferase in osteosarcoma and its effect on proliferation and sensitivity to cisplatin

open access: yesZhongguo aizheng zazhi, 2020
Background and purpose: O-GlcNAc transferase (OGT) is widely involved in biological behaviors of tumor cells and associated with tumor progression. In this study, we measured expression level of OGT in osteosarcoma tissues, and evaluated its effect on ...

A non-sense mutation in the putative anti-mutator gene ada/alkA of Mycobacterium tuberculosis and M. bovis isolates suggests convergent evolution [PDF]

open access: yes, 2007
Background: Previous studies have suggested that variations in DNA repair genes of W-Beijing strains may have led to transient mutator phenotypes which in turn may have contributed to host adaptation of this strain family. Single nucleotide polymorphism (

OGT suppresses S6K1-mediated macrophage inflammation and metabolic disturbance [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
Significance Overnutrition leads to metabolic disorders including obesity and diabetes. Studies have shown that enhanced inflammation is an essential player in the progression of metabolic diseases. However, how immune cells sense nutritional status and contribute to whole-body metabolism are largely unknown.

35 Individuals With HUWE1‐Related Neurodevelopmental Disorder and Suggested Clinical Evaluations

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT HUWE1 (HECT, UBA, and WWE Domain Containing E3 Ubiquitin Protein Ligase1, OMIM 300697), located at Xp11.22, encodes a ubiquitin ligase that is highly conserved across species. Genetic variants in HUWE1 described in multiple independent studies cause X‐linked intellectual disability, including in the patients identified by Juberg, Marsidi, and ...
