ABSTRACT: N-acetyltransferase 10 (NAT10), the only known mRNA ac4C “writer,” plays a significant role in several human diseases, including CRC and gastric cancer. As NAT10 can activate or repress important signaling pathways, such as the EMT pathway, DNA damage repair, or apoptosis, by catalyzing the ac4C modification of oncogene mRNA, targeting NAT10 shows great potential for inhibiting cancer cell malignant progression in vitro and in vivo. This complex network of colorectal cancer progression mediated by NAT10 remains to be identified, which can expand cancer therapy options. To identify potential NAT10-regulated ac4C targets, we checked RIP-Transcriptome Sequencing in human colorectal cancer cell SW620.

Project description:We show that NAT10-ac4C axis significantly regulates cell fates. To identify the molecular mechanisms of NAT10-ac4C-ANP32B axis in cell-fate transitions, we construct shNAT10 and shANP32B hESCs. acRIP-seq of shCTR and shNAT10 hESCs. We profiled ATAC-seq in shCTR, shNAT10, and shANP32B hESCs. We profiled H3K4me3 and H3K27me3 modifications and the binding of ANP32B by CUT&Tag in shCTR and shNAT10 hESCs.
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:The enzyme N-acetyltransferase 10 (NAT10), known as the exclusive catalyst for N4-acetylcytidine (ac4C) modification, has been associated with various cellular processes, including tRNA acetylation, 18S rRNA biogenesis, mRNA stability, and translational efficiency. Despite extensive investigation into its molecular mechanisms in vitro, the physiological function of NAT10 under normal conditions has remained largely undefined. In this study, we found that the deficiency of NAT10 led to a disruption of T cell development at steady state, and identified a pivotal role for NAT10 in preserving the pathogenicity of naïve CD4+ T cells to induce adoptive transfer colitis. Mechanistically, the lack of NAT10 triggers the diminished stability of the anti-apoptotic gene Bag3, initiating a cascade of events that includes the upregulation of apoptosis-related genes and an accelerated rate of apoptosis in T cells. Our findings reveal a previously unrecognized role of the NAT10-ac4C-Bag3 axis in maintaining T cell homeostasis in vivo.

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.
