Abstract:
Protein O-GlcNAcylation is a post-translational modification coupled to cellular metabolic plasticity. Aberrant O-GlcNAcylation has been observed in many cancers including endometrial cancer (EC), a common malignancy in women. However, clinical characterization of dysregulated O-GlcNAcylation homeostasis in EC and interrogating its molecular mechanism remain incomplete. Here we report that O-GlcNAcylation level is positively correlated with EC histologic grade in a Chinese cohort containing 219 tumors, validated in The Cancer Genome Atlas dataset. Increasing O-GlcNAcylation in patient-derived endometrial epithelial organoids promotes proliferation and stem-like cell properties, whereas decreasing O-GlcNAcylation limits the growth of endometrial cancer organoids. CRISPR screen and biochemical characterization reveal that tumor suppressor F-box only protein 31 (FBXO31) regulates O-GlcNAcylation homeostasis in EC by ubiquitinating the O-GlcNAc transferase OGT. Downregulation of O-GlcNAcylation impedes EC tumor formation in mouse models. Collectively, our study highlights O-GlcNAcylation as a useful stratification marker and a therapeutic vulnerability for the advanced, poorly differentiated EC cases.

Xu S, Yin K, Xu X, Fu L, Wu R. O-GlcNAcylation reduces proteome solubility and regulates the formation of biomolecular condensates in human cells. Nature communications 2025 16(1) 40307207
Abstract:
O-GlcNAcylation plays critical roles in the regulation of protein functions and cellular activities, including protein interactions with other macromolecules. While the formation of biomolecular condensates (or biocondensates) regulated by O-GlcNAcylation in a few individual proteins has been reported, systematic investigation of O-GlcNAcylation on the regulation of biocondensate formation remains to be explored. Here we systematically study the roles of O-GlcNAcylation in regulating protein solubility and its impacts on RNA-protein condensates using mass spectrometry-based chemoproteomics. Unexpectedly, we observe a system-wide decrease in the solubility of proteins modified by O-GlcNAcylation, with glycoproteins involved in focal adhesion and actin binding exhibiting the most significant decrease. Furthermore, O-GlcNAcylation sites located in disordered regions and with fewer acidic and aromatic residues nearby are related to a greater drop in protein solubility. Additionally, we discover that a specific group of O-GlcNAcylation events promotes the dissociation of RNA-protein condensates under heat stress, while some enhance the formation of RNA-protein condensates during the recovery phase. Using site mutagenesis, inhibition of O-GlcNAc transferase, and fluorescence microscopy, we validate that O-GlcNAcylation regulates the formation of biocondensates for YTHDF3 and NUFIP2. This work advances our understanding of the functions of protein O-GlcNAcylation and its roles in the formation of biomolecular condensates.
