Project description:N4-acetylcytidine (ac4C), a conserved chemical modification in eukaryotic prokaryotes that is catalyzed by the N-acetyltransferase 10 (NAT10) enzyme, plays a crucial role in promoting mRNA stability and translation. However, the biological function and mechanisms of NAT10-mediated ac4C in human cancer were poorly defined. In order to investigate the regulatory mechanism of NAT10 in gastric cancer, we performed ac4C RIP-seq(acRIP-seq) analysis in AGS cells with NAT10 knockout compared with control in two repeats.

Project description:RNA modification play vital roles in renal fibrosis. However, whether ac4C modification functions in renal fibrogenesis remains unknown. Here, we found that NAT10-ac4C axis plays pro—fibrotic role in kidney. ac4C RIP sequencing demonstrated NAT10-ac4C axis functions via regulating multiple master genes of exosome secretion in tubular epithelial cells. In summary, targeting NAT10-ac4C axis is a promising strategy for renal fibrosis.

Project description:NAT10-catalyzed N4-acetylcytidine (ac4C) has emerged as a vital post-transcriptional modulator on the coding transcriptome by promoting mRNA stability. To explore the transcriptome-wide profile of ac4C modification, we mapped the locations of ac4C modification on wild-type (WT) hESCs and NAT10 KD hESCs by NaCNBH3-based chemical ac4C sequencing (ac4C-seq).

Project description:Increased differentiation or activity of osteoclasts is the key pathogenic factor of postmenopausal osteoporosis (PMOP). N4‐acetylcytidine (ac4C) modification, catalyzed by Nat10, is a novel post-transcriptional mRNA modification related to many diseases. However, its impact on regulating osteoclast activation in PMOP remains uncertain. Here, we initially observed that Nat10-mediated ac4C positively correlates with osteoclast differentiation of monocytes and low bone mass in PMOP. The specific knockout of Nat10 in monocytes and remodelin, a Nat10 inhibitor, alleviates ovariectomized (OVX)-induced bone loss by downregulating osteoclast differentiation. Mechanistically, epitranscriptomic analyses reveal that the nuclear factor of activated T cells cytoplasmic 1 (Nfatc1) is the key downstream target of ac4C modification during osteoclast differentiation. Subsequently, translatomic results demonstrate that Nat10-mediated ac4C enhances the translation efficiency of Nfatc1, thereby inducing Nfatc1 expression and consequent osteoclast maturation. Cumulatively, these findings reveal the promotive role of Nat10 in osteoclast differentiation and PMOP from a novel field of RNA modifications and suggest that Nat10 can be a target of epigenetic therapy for preventing bone loss in PMOP.

Project description:Background: Heart failure (HF), characterized by cardiac remodeling, is associated with abnormal epigenetic processes and aberrant gene expression. Here, we aimed to elucidate the effects and mechanisms of N-acetyltransferase 10 (NAT10)-mediated N4?acetylcytidine (ac4C) acetylation during cardiac remodeling. Methods: NAT10 and ac4C expression were detected in both human and mouse subjects with cardiac remodeling through multiple assays. Subsequently, acetylated RNA immunoprecipitation and sequencing (acRIP-seq), thiol (SH)-linked alkylation for the metabolic sequencing of RNA (SLAM-seq), and ribosome sequencing (Ribo-seq) were employed to elucidate the role of ac4C-modified post-transcriptional regulation in cardiac remodeling. Additionally, functional experiments involving the overexpression or knockdown of NAT10 were conducted in mice models challenged with Ang II and transverse aortic constriction (TAC). Results: NAT10 expression and RNA ac4C levels were increased in in vitro and in vivo cardiac remodeling models, as well as in patients with cardiac hypertrophy. Silencing and inhibiting NAT10 attenuated Ang II-induced cardiomyocyte hypertrophy and cardio-fibroblast activation. Next-generation sequencing revealed ac4C changes in both mice and humans with cardiac hypertrophy were associated with changes in global mRNA abundance, stability and translation efficiency. Mechanistically, NAT10 could enhance the stability and translation efficiency of CD47 and ROCK2 transcripts by upregulating their mRNA ac4C modification, thereby resulting in an increase in their protein expression during cardiac remodeling. Furthermore, the administration of Remodelin, a NAT10 inhibitor, has been shown to prevent cardiac functional impairments in mice subjected to TAC by suppressing cardiac fibrosis, hypertrophy, and inflammatory responses, while also regulating the expression levels of CD47 and ROCK2. Conclusions: Therefore, our data suggest that modulating epitranscriptomic processes, such as ac4C acetylation through NAT10, may be a promising therapeutic target against cardiac remodeling.

Project description:To determine the role of NAT10 in promoting the progression of ccRCC, we performed RNA sequencing (RNA-Seq) and ac4C-modified RNA immunoprecipitation sequencing (acRIP-seq) on four pairs of ccRCC tissues and their adjacent tissues. A comprehensive analysis of acRIP-seq and RNA-seq showed that the expression and acetylation levels of 199 transcripts were increased . We selected 11 candidate genes of interest and analyzed their acetylation levels. Since ac4C modification can improve mRNA stability, the 11 candidate genes were verified, and the results showed that only NFE2L3 mRNA levels decreased in 786-O cells and A498 cells after NAT10 stable knockdown , so we decided to study the mechanism of action of NFE2L3 in ccRCC.

Project description:Pancreatic cancer is a lethal diease with high tendency of metastasis. Howerver, the mechanisms of pancreatic cancer are sitill unclear. To explore the roles of N4-acetylation (ac4C) RNA modification and its involved N-Acetyltransferase 10 (NAT10) in pancreatic ductal adenocarcinoma (PDAC), we performed profiling by high throughput sequencing. In this study, we investigate the effects of NAT10 knockdown on N4-acetylcytidine (ac4C) modification in mRNA within PANC-1 cells using ac4C-seq. By employing RNA interference to specifically knock down NAT10 expression in PANC-1 cells, we aim to elucidate its impact on ac4C RNA modifications, which have been implicated in various cellular processes and cancer progression. Total RNA was extracted and mRNA was captured and treated with sodium borohydride (NaBH4) for detection of ac4C sites.Following library preparation, sequencing was performed on an Illumina Novaseq 6000 platform. Bioinformatics analyses identified significant changes in ac4C modification patterns due to NAT10 depletion. This dataset provides a valuable resource for further exploration of ac4C modifications in mRNA and their role in PDAC.

Project description:RNA modification represents an important post-transcriptional regulatory mechanism in acute myeloid leukemia (AML), however the function and mechanism of RNA acetylation ac4C in AML remains elusive. Here, we report that NAT10, as the ac4C writing enzyme, plays a critical oncogenic function in AML and represents a promising therapeutic target for AML. To understand the mechanisms underlying the function of NAT10 as an RNA ac4C writer in AML, we profiled ac4C modification in the transcriptome of MOLM13 cells using a refined ac4C RNA immunoprecipitation and high throughput sequencing (RacRIP-seq) protocol, and performed systematic calibration with a modification-free control library generated from the in vitro- transcribed MOLM13 transcriptome (referred to as IVT control) to eliminate most of the false- positive signals. We also applied the RacRIP-seq in NAT10 knockdown and control MOLM13 cells to characterize NAT10 targets.
