“…5 The level of m 6 A, m 7 G or ac4C modifications in mRNA-specific motifs is variable depending on protein-binding, resulting in changes to mRNA stability and translation efficiency. [6][7][8][9][10][11] These modifications are responsible for tumour proliferation, metastasis, maintenance of stemness and cellfate decisions. 10,[12][13][14] Previous studies demonstrate that METTL3, an N6-methyltransferase that methylates adenosine residues at the N6 position of some RNAs, is involved in the m 6 A modification of ITGA6 and the AFF4/NF-κB/MYC pathway.…”

Background Dysregulation of the epitranscriptome causes abnormal expression of oncogenes in the tumorigenic process. Previous studies have shown that NAT10 can regulate mRNA translation efficiency through RNA acetylation. However, the role of NAT10‐mediated acetylation modification in bladder cancer remains elusive. Methods The clinical value of NAT10 was estimated according to NAT10 expression pattern based on TCGA data set and the tumor tissue array. Acetylated RNA immunoprecipitation sequencing was utilized to explore the role of NAT10 in mRNA ac4C modification. Translation efficiency and mRNA stability assay were applied to study the effect of NAT10‐deletion on target genes. The nude mouse model and genetically engineered mice were conducted to further verify the characteristics of NAT10 in promoting BLCA progression and regulating downstream targets. Results NAT10 was essential for the proliferation, migration, invasion, survival and the stem‐cell‐like properties of bladder cancer cell lines. NAT10 was responsible for mRNA ac4C modification in BLCA cells, including BCL9L, SOX4 and AKT1. Deficient NAT10 in both xenograft and transgenic mouse models of bladder cancer reduced the tumor burden. Furthermore, acetylated RNA immunoprecipitation sequencing data and RNA immunoprecipitation qPCR results revealed that NAT10 is responsible for a set of ac4C mRNA modifications in bladder cancer cells. Inhibition of NAT10 led to a loss of ac4C peaks in these transcripts and represses the mRNA's stability and protein expression. Mechanistically, the ac4C reduction modification in specific regions of mRNAs resulting from NAT10 downregulation impaired the translation efficiency of BCL9L, SOX4 and AKT1 as well as the stability of BCL9L, SOX4. Conclusions In summary, these findings provide new insights into the dynamic characteristics of mRNA's post‐transcriptional modification via NAT10‐dependent acetylation and predict a role for NAT10 as a therapeutic target in bladder cancer. Highlights NAT10 is highly expressed in BLCA patients and its abnormal level predicts bladder cancer progression and low overall survival rate. NAT10 is necessary and sufficient for BLCA tumourigenic properties. NAT10 is responsible for ac4C modification of target transcripts, including BCL9L, SOX4 and AKT1. NAT10 may serve as an effective and novel therapeutic target for BLCA.

“…NAT10, as the only identified acetyltransferase, is thought to play critical roles in promoting mRNA stability and maintaining translation fidelity through ac4C modification on the specific sequence of target mRNAs (16). The dysregulation of NAT10 inhibited cell development progress and led to various diseases, such as gastric cancer and systemic lupus erythematosus (17)(18)(19).…”

NAT10 Maintains OGA mRNA Stability Through ac4C Modification in Regulating Oocyte Maturation

et al. 2022

In vitro maturation (IVM) refers to the process of developing immature oocytes into the mature in vitro under the microenvironment analogous to follicle fluid. It is an important technique for patients with polycystic ovary syndrome and, especially, those young patients with the need of fertility preservation. However, as the mechanisms of oocyte maturation have not been fully understood yet, the cultivation efficiency of IVM is not satisfactory. It was confirmed in our previous study that oocyte maturation was impaired after N-acetyltransferase 10 (NAT10) knockdown (KD). In the present study, we further explored the transcriptome alteration of NAT10-depleted oocytes and found that O-GlcNAcase(OGA) was an important target gene for NAT10-mediated ac4C modification in oocyte maturation. NAT10 might regulate OGA stability and expression by suppressing its degradation. To find out whether the influence of NAT10-mediated ac4C on oocyte maturation was mediated by OGA, we further explored the role of OGA in IVM. After knocking down OGA of oocytes, oocyte maturation was inhibited. In addition, as oocytes matured, OGA expression increased and, conversely, O-linked N-acetylglucosamine (O-GlcNAc) level decreased. On the basis of NAT10 KD transcriptome and OGA KD transcriptome data, NAT10-mediated ac4C modification of OGA might play a role through G protein–coupled receptors, molecular transduction, nucleosome DNA binding, and other mechanisms in oocyte maturation. Rsph6a, Gm7788, Gm41780, Trpc7, Gm29036, and Gm47144 were potential downstream genes. In conclusion, NAT10 maintained the stability of OGA transcript by ac4C modification on it, thus positively regulating IVM. Moreover, our study revealed the regulation mechanisms of oocytes maturation and provided reference for improving IVM outcomes. At the same time, the interaction between mRNA ac4C modification and protein O-GlcNAc modification was found for the first time, which enriched the regulation network of oocyte maturation.

“…Accumulating evidence has suggested the participation of other mRNA modification in oncogenesis or cancer development. Zhang et al., for example, have found NAT10-mediated mRNA ac4C modification in promotion of gastric cancer (GC) metastasis and epithelial-to-mesenchymal transition (EMT) ( 1 ). The Y box binding protein 1 (YBX1)-mediated m5C modification promoted mRNA stability, which activated oncogenesis of urothelial carcinoma of the bladder ( 2 ).…”

BackgroundPhosphorylated CTD-interacting factor 1 (PCIF1) is identified as the only known methyltransferase of N6,2′-O-dimethyladenosine (m6Am) in mRNA. However, its oncogenic and immunogenic role in cancer research is at an initial stage.MethodsHerein, we carried out a pan-cancer analysis of PCIF1, with a series of datasets (e.g., TIMER2.0, GEPIA2, cBioPortal).ResultsPCIF1 expression was higher in most cancers than normal tissues and was discrepant across pathological stages. Highly expressed PCIF1 was positively correlated with overall survival (OS) or disease-free survival (DFS) of some tumors. PCIF1 expression had a positive correlation with CD4+ T-cell infiltration in kidney renal clear cell carcinoma (KIRC), CD8+ T cells, macrophages, and B cells in thyroid carcinoma (THCA), and immune checkpoint genes (ICGs) in LIHC but a negative correlation with CD4+ T cells, neutrophils, myeloid dendritic cells, and ICGs in THCA. It also affected tumor mutational burden (TMB) and microsatellite instability (MSI) of most tumors.ConclusionPCIF1 expression was correlated with cancer prognosis and immune infiltration, suggesting it to be a potential target for cancer therapy.
