Yang S, Liu H, Ni H, Jiang L, Yang M, Chen Q, Zhou J, Yu F. O-GlcNAcylation regulates phagocytosis by promoting Ezrin localization at the cell cortex. Journal of genetics and genomics = Yi chuan xue bao 2023 36796536
Abstract:
O-GlcNAcylation is a post-translational modification that serves as a cellular nutrient sensor and participates in multiple physiological and pathological processes. However, it remains uncertain whether O-GlcNAcylation is involved in the regulation of phagocytosis. Here, we demonstrate a rapid increase in protein O-GlcNAcylation in response to phagocytotic stimuli. Knockout of O-GlcNAc transferase or pharmacological inhibition of O-GlcNAcylation dramatically blocks phagocytosis, resulting in the disruption of retinal structure and function. Mechanistic studies reveal that O-GlcNAc transferase interacts with Ezrin, a membrane-cytoskeleton linker protein, to catalyze its O-GlcNAcylation. Our data further show that Ezrin O-GlcNAcylation promotes its localization to the cell cortex, thereby stimulating the membrane-cytoskeleton interaction needed for efficient phagocytosis. These findings identify a previously unrecognized role for protein O-GlcNAcylation in phagocytosis with important implications in both health and diseases.

Zhao Y, Yue S, Zhou X, Guo J, Ma S, Chen Q. O-GlcNAc transferase promotes the nuclear localization of the focal adhesion-associated protein Zyxin to regulate UV-induced cell death. The Journal of biological chemistry 2022 298(4) 35227760
Abstract:
Zyxin is a zinc-binding phosphoprotein known to regulate cell migration, adhesion, and cell survival. Zyxin also plays a role in signal transduction between focal adhesions and the nuclear compartment. However, the mechanism of Zyxin shuttling to nucleus is still unclear. Here, we identify that the GlcNAc transferase (O-linked GlcNAc [O-GlcNAc] transferase) can O-GlcNAcylate Zyxin and regulate its nuclear localization. We show that O-GlcNAc transferase O-GlcNAcylates Zyxin at two residues, serine 169 (Ser-169) and Ser-246. In addition, O-GlcNAcylation of Ser-169, but not Ser-246, enhances its interaction with 14-3-3γ, which is a phosphoserine/threonine-binding protein and is reported to bind with phosphorylated Zyxin. Furthermore, we found that 14-3-3γ could promote the nuclear localization of Zyxin after Ser-169 O-GlcNAcylation by affecting the function of the N-terminal nuclear export signal sequence; functionally, UV treatment increases the O-GlcNAcylation of Zyxin, which may enhance the nuclear location of Zyxin. Finally, Zyxin in the nucleus maintains homeodomain-interacting protein kinase 2 stability and promotes UV-induced cell death. In conclusion, we uncover that the nuclear localization of Zyxin can be regulated by its O-GlcNAcylation, and that this protein may regulate UV-induced cell death.

Epithelial STAT6 O-GlcNAcylation drives a concerted anti-helminth alarmin response dependent on tuft cell hyperplasia and Gasdermin C. Immunity 2022 55(4) 35385697
Abstract:
The epithelium is an integral component of mucosal barrier and host immunity. Following helminth infection, the intestinal epithelial cells secrete "alarmin" cytokines, such as interleukin-25 (IL-25) and IL-33, to initiate the type 2 immune responses for helminth expulsion and tolerance. However, it is unknown how helminth infection and the resulting cytokine milieu drive epithelial remodeling and orchestrate alarmin secretion. Here, we report that epithelial O-linked N-Acetylglucosamine (O-GlcNAc) protein modification was induced upon helminth infections. By modifying and activating the transcription factor STAT6, O-GlcNAc transferase promoted the transcription of lineage-defining Pou2f3 in tuft cell differentiation and IL-25 production. Meanwhile, STAT6 O-GlcNAcylation activated the expression of Gsdmc family genes. The membrane pore formed by GSDMC facilitated the unconventional secretion of IL-33. GSDMC-mediated IL-33 secretion was indispensable for effective anti-helminth immunity and contributed to induced intestinal inflammation. Protein O-GlcNAcylation can be harnessed for future treatment of type 2 inflammation-associated human diseases.

Abstract:
Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers and its dismal prognosis indicates the urgent need to elucidate the potential oncogenic mechanisms. SIRT7 is a classic NAD+-dependent deacetylase that stabilizes the transformed state of cancer cells. However, its functional roles in PDAC are still unclear. Here, we found that SIRT7 expression is upregulated and predicts poor prognosis in PDAC. Then we screened the new interacting proteins of SIRT7 by mass spectrometry and the results showed that SIRT7 can interact with O-GlcNAc transferase (OGT). O-GlcNAcylation stabilizes the SIRT7 protein by inhibiting its interaction with REGγ to prevent degradation, and hyper-O-GlcNAcylation in pancreatic cancer cells leads to hypoacetylation of H3K18 via SIRT7, which promotes transcriptional repression of several tumour suppressor genes. In addition, SIRT7 O-GlcNAcylation at the serine 136 residue (S136) is required to maintain its protein stability and deacetylation ability. In vivo and in vitro experiments showed that blocking SIRT7 O-GlcNAcylation at S136 attenuates tumour progression. Collectively, we demonstrate that O-GlcNAcylation is an important post-translational modification of SIRT7 in pancreatic cancer cells, and elucidating this mechanism of SIRT7 is expected to pave the way for the development of novel therapeutic methods in the future.

Abstract:
Chromatin modifier metastasis-associated protein 1 (MTA1), closely associated with tumor angiogenesis in breast cancer, plays an important role in gene expression and cancer cell behavior. Recently, an association between O-GlcNAc transferase (OGT) and MTA1 was identified by mass spectroscopy. However, the potential relationship between MTA1 and O-GlcNAc modification has not yet explored.
