SUMOylation targets O-GlcNAcase to chaperone-mediated autophagy. [PDF]

open access: yesJ Biol Chem
O-GlcNAcase (OGA) is the sole eraser for the intracellular O-GlcNAc. OGA has many roles in distinct biological processes, such as cancer and embryonic stem cells, but its precise regulatory mechanism is far from being understood. Herein, we studied the small ubiquitin-like modifier (SUMO) modification of OGA and found that OGA is SUMOylated at K358 ...

Chronically Elevated O-GlcNAcylation Limits Nitric Oxide Production and Deregulates Specific Pro-Inflammatory Cytokines

open access: yesFrontiers in Immunology, 2022
Inflammation is the immune response to harmful stimuli, including pathogens, damaged cells and toxic compounds. However, uncontrolled inflammation can be detrimental and contribute to numerous chronic inflammatory diseases, such as insulin resistance. At

Drosophila O-GlcNAcase Deletion Globally Perturbs Chromatin O-GlcNAcylation. [PDF]

open access: yesJ Biol Chem, 2016
Gene expression during Drosophila development is subject to regulation by the Polycomb (Pc), Trithorax (Trx), and Compass chromatin modifier complexes. O-GlcNAc transferase (OGT/SXC) is essential for Pc repression suggesting that the O-GlcNAcylation of proteins plays a key role in regulating development. OGT transfers O-GlcNAc onto serine and threonine

Loss of O-GlcNAcase catalytic activity leads to defects in mouse embryogenesis. [PDF]

open access: yesJ Biol Chem, 2021
O-GlcNAcylation is an essential post-translational modification that has been implicated in neurodevelopmental and neurodegenerative disorders. O-GlcNAcase (OGA), the sole enzyme catalyzing the removal of O-GlcNAc from proteins, has emerged as a potential drug target.

O-GlcNAcase regulates pluripotency states of human embryonic stem cells. [PDF]

open access: yesStem Cell Reports
Understanding the regulation of human embryonic stem cells (hESCs) pluripotency is critical to advance the field of developmental biology and regenerative medicine. Despite the recent progress, molecular events regulating hESC pluripotency, especially the transition between naive and primed states, still remain unclear.

The intra-mitochondrial O-GlcNAcylation system rapidly modulates OXPHOS function and ROS release in the heart

open access: yesCommunications Biology, 2022
An in vitro assay in isolated heart mitochondria reveals that O-GlcNAcase inhibitor NButGT rapidly increases protein O-GlcNAcylation leading to increased respiratory capacity and complex I activity and decreased ROS release.

Liuwei Dihuang formula ameliorates chronic stress-induced emotional and cognitive impairments in mice by elevating hippocampal O-GlcNAc modification

open access: yesFrontiers in Neuroscience, 2023
A substantial body of evidence has indicated that intracerebral O-linked N-acetyl-β-D-glucosamine (O-GlcNAc), a generalized post-translational modification, was emerging as an effective regulator of stress-induced emotional and cognitive impairments. Our

Blocking ATM Attenuates SKOV3 Cell Proliferation and Migration by Disturbing OGT/OGA Expression via hsa-miR-542-5p

open access: yesFrontiers in Oncology, 2022
Blocking ataxia telangiectasia mutated (ATM), a crucial player in DNA repair responses, has been proposed as a promising strategy in anti-cancer therapy.

Reduced O-GlcNAcase expression promotes mitotic errors and spindle defects. [PDF]

open access: yesCell Cycle, 2016
Alterations in O-GlcNAc cycling, the addition and removal of O-GlcNAc, lead to mitotic defects and increased aneuploidy. Herein, we generated stable O-GlcNAcase (OGA, the enzyme that removes O-GlcNAc) knockdown HeLa cell lines and characterized the effect of the reduction in OGA activity on cell cycle progression.

Increasing O-GlcNAcylation level on organ culture of soleus modulates the calcium activation parameters of muscle fibers. [PDF]

open access: yesPLoS ONE, 2012
O-N-acetylglucosaminylation is a reversible post-translational modification which presents a dynamic and highly regulated interplay with phosphorylation.
