NAT10 modulates fatty acid metabolism of palmitate driven MCF7 in ac4C dependent manner

Project description:We show that non-toxic exogenous palmitate uptake in MCF7 cells promotes NAT10 expression and NAT10-dependent ac4C RNA modification. It was previously reported that NAT10 modulates the addition of ac4C on RNA transcripts in normal and cancer conditions. However, no study report the impact of NAT10 in palmitate driven cells. Here we performed RNA immunoprecipitation sequencing (RIP-seq) in palmitate loaded MCF7 knockdown with NAT10 siRNA. Based on the pathways and enrichment landscape identified. We found that ac4C peaks of fatty acid metabolic genes including ELOVL6, ACSL1, ACSL3, ACSL4, ACADSB and ACAT1 were significantly decreased upon knockdown with NAT10 siRNA. Overall, our results revealed the impact of NAT10 as a regulator of fatty acid metabolism in ac4C-dependent manner

Transcriptomic profiling in NAT10 knockdown acute myeloid leukemia cells

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 determine the impact of NAT10-mediated ac4C on gene expression, we conducted high throughput RNA-sequencing (RNA-seq) in NAT10-knockdown and control MOLM13 cells.

RNA-seq analysis of mRNA expression profiles upon NAT10 depletion

Project description:NAT10 (N-acetyltransferase-like protein) regulates N4-acetylcytidine formation in RNA. However, the biological function and mechanisms of NAT10 were poorly defined. To understand the molecular mechanism by which NAT10 affect GC progression, we performed RNA sequencing (RNA-seq) in AGS cells with NAT10 knockout and in BGC823 cells with shNAT10, with independent biological replicates.

NAT10 inhibition improves cellular phenotypes of Hutchinson-Gilford progeria syndrome by restoring the Transportin-1 pathway

Project description:In this experiment, we aim to examine the role of NAT10 inhibition in Hutchinson-Gilford progeria syndrome (HGPS), a rare but devastating premature ageing syndrome caused by a mutation in the LMNA gene. NAT10 inhibition improves HGPS cellular phenotypes by releasing Transportin-1 (TNPO1) from the cytoplasm, restoring the TNPO1 pathway and allowing hnRNPA1 and NUP153 nuclear import, TPR anchorage at the nuclear pore complexes and RanGTP gradient re-balancing. We have promoted NAT10 inhibition by two ways in normal or patient derived primary skin fibroblasts; the NAT10 inhibitor Remodelin, and an siRNA directly targeting NAT10 (siNAT10). In addition, we have also used an siRNA against TNPO1 and a combined siTNPO1 and siNAT10 treatment. This is a 2-factor design, with treatment (Remodelin vs untreated, or siNAT10 vs siCT) and condition (HGPS vs normal fibroblasts) as the two conditions. Transcriptional profiling was performed using HumanHT-12 v4 Expression BeadChip microarrays, and all conditions were run in triplicate.

NAT10-mediated N4-acetylcytidine of RNA Contributes to Post-transcriptional Regulation of Mouse Oocyte Maturation In Vitro

Project description:N4-acetylcytidine (ac4C), a newly identified epigenetic modification within mRNAs, has been characterized as a crucial regulator of mRNA stability and translation efficiency. And NAT10 is the only known RNA acetyltransferase. In our study, we documented the down-regulated expression of both ac4C and NAT10 during meiotic maturation of mouse oocytes. NAT10 knockdown resulted in ac4C reduction and impaired mouse oocyte maturation in vitro. These results indicated that NAT10-mediated ac4C modification plays a critical regulatory role in oocyte meiotic maturation. We further performed high-throughput sequencing with NAT10-overexpressed HEK293T cells and NAT10-binding transcripts to investigate the genes modulated by NAT10-mediated ac4C modification.

NAT10 depletion suppresses fatty acid metabolism in MCF7 breast cancer cells

Project description:NAT10 is an RNA cytidine transferase known to add acetyl group on RNA transcripts thereby promoting translational efficiency. It was reported that NAT10 regulates epithelial to mesenchymal transition (EMT), DNA damage, and cell proliferation in cancers. However, weather NAT10 regulates other crucial pathways is unknown. In our study we conducted gene expression profiling analysis using data obtained from RNA-seq of MCF7 NAT10 KO and scramble control. High throughput sequencing revealed fatty acid metabolism as the top enriched pathway with fatty acid metabolic genes such ELOVL6, ACSL1, ACSL3, ACSL4, ACADSB, and ACAT1 were found to be differentially down-regulated. Overall our results revealed NAT10 depletion suppresses fatty acid metabolism in MCF7.
