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:Understanding erythropoiesis involves comprehending the process of erythroid differentiation, yet there are still numerous mysteryin this field.The purpose of this research was to look at NAT10-mediated regulation of gene expression during erythroid differentiation. NAT10, an acetyltransferase, has been shown to be highly expressed in the early stages of erythroid differentiation and to play an important role in stimulating erythroid differentiation.We identified ac4C modification on RAC2 and GDF15 mRNAs by acetylated RNA immunoprecipitation sequencing (acRIP-seq) and ribosome profiling sequencing (Ribo-seq) combined with RNA sequencing, which are significant downstream targets of NAT10 to improve erythropoiesis . Collectively, our data suggest that NAT10 promotes erythropoiesis by acetylating RAC2 and GDF15 mRNA associated with erythroid progenitors, thereby promoting erythroid differentiation by increasing RNA stability and translation efficiency. This study reveals unexpected patterns in the regulation of erythroid differentiation, advances our understanding of the regulatory network for erythroid differentiation from multiple perspectives, and identifies potential clinical targets for controlling erythroid regeneration.

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:N-acetyltransferase 10 (NAT10) is a multifunctional enzyme that harbors RNA acetyltransferase and RNA helicase domains and has emerged as a therapeutic vulnerability in solid and hematological malignancies. By coupling Proteolysis Targeting Chimera-mediated degradation of NAT10 with a deep mutational scanning assay, followed by biochemical, cellular, and in vivo validations, we find that the RNA helicase domain of NAT10 enhances cancer cell proliferation and tumor growth. This proliferative function of NAT10 is independent of RNA acetylation but requires its RNA-binding activity. The RNA helicase domain of NAT10 is required for 18S rRNA binding, promoting biogenesis of the 40S ribosomal subunit, while simultaneously interfering with the deposition of the conserved 18S rRNA modification m¹acp³Ψ. Loss of m¹acp³Ψ in 18S rRNA enhances cancer cell proliferation, revealing that NAT10 promotes the biogenesis of hypomodified ribosomes to facilitate tumor growth. These findings uncover a previously unrecognized mechanism by which NAT10 promotes cancer cell proliferation and establish its RNA helicase domain as a potential therapeutic target.
