Project description:N4-acetylcytidine (ac4C) is a lately discovered nucleotide modification that has been shown to be closely implicated in cancer. N-acetyltransferase10(NAT10) acts as an enzyme that regulates mRNA acetylation modifications. Currently, the role of NAT10-mediated RNA acetylation modification in cervical cancer remains to be elucidated. On the basis of transcriptome analysis of TCGA and GEO open datasets (GSE52904, GSE29570, GSE122697), NAT10 is upregulated in cervical cancer tissues and correlated with poor prognosis. Knockdown of NAT10 suppressed the cell proliferation, invasion, and migration of cervical cancer cells. The in vivo oncogenic function of NAT10 was also confirmed in xenograft models. Combined RNA-seq and acRIP-seq analysis revealed HNRNPUL1 as the target of NAT10 in cervical cancer. NAT10 positively regulate HNRNPUL1 expression by promoting ac4C modification and stability of HNRNPUL1 mRNA. Furthermore, depletion of HNRNPUL1 suppressed the cell division, invasion, and migration of cervical cancer. HNRNPUL1 overexpression partially restored cellular function in cervical cancer cells with NAT10 knockdown. Thus, this study demonstrates that NAT10 contributes to cervical cancer progression by enhancing HNRNPUL1 mRNA stability via ac4C modification, and NAT10-ac4C-HNRNPUL1 axis might be a potential target for cervical cancer therapy.

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: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.

Project description:Mammalian oocyte maturation is driven by strictly translational regulation of maternal mRNAs stored in the cytoplasm. However, the function and mechanism of post-transcriptional chemical modifications especially the newly identified N4-acetylcytidine (ac4C) catalyzed by N-acetyltransferase 10 (NAT10) in this process are previously unknown. In this study, we developed a low-input ac4C sequencing technology—ac4C LACE-seq and mapped 8241 ac4C peaks at the whole transcriptome level using 50 mouse oocytes at the germinal vesicle (GV) stage. We profiled the mRNA landscapes of NAT10-interactions and ac4C modifications. The NAT10-interacted and ac4C modified transcripts displayed association with high translation efficiency in oocytes. Oocyte-specific Nat10 knockout wiped out ac4C signals in oocytes and caused severe defects in meiotic maturation and female infertility. ac4C LACE-seq results indicated that Nat10 deletion led to a failure of ac4C deposition on mRNAs encoding key maternal factors such as MAY2, ZAR1, BTG4 and cyclin B1 that regulate transcriptome stability and maternal-to-zygotic transition. Nat10-deleted oocytes had decreased mRNA translation efficiencies during meiotic maturation, partially due to the direct inhibition ac4C sites on specific transcripts. In sum, we developed low-input, high-sensitivity mRNA ac4C profiling approach and highlighted the important physiological function of ac4C in precise regulation of the oocyte meiotic maturation by enhancing translation efficiency.

Project description:Purpose: The goal of this study is to compare NGS-derived wild type and Hnrnpul1 knockout (Hnrnpul1-/-) RAW 264.7 cells transcriptomes with or without LPS stimulation. Methods: Sequancing was performed by Novogene China Co. Ltd. RNA profiles of wild type and Hnrnpul1-/- RAW 264.7 cells as well as LPS stimulated (10 h) wild type and Hnrnpul1-/- RAW 264.7 cells were generated by deep sequencing using Illumina Novaseq 6000. Index of the reference genome was built using Hisat2 v2.0.5 and paired-end clean reads were aligned to the reference genome using Hisat2 v2.0.5. featureCounts v1.5.0-p3 was used to count the reads numbers mapped to each gene. And then FPKM of each gene was calculated based on the length of the gene and reads count mapped to this gene. Method of TMM was used to normalize the readcount. Negative binomial distribution model was used to calculate the P value, and FDR was calculated by the method of Benjaminiand Hochberg. Results: Using an optimized data analysis workflow, we mapped about 40 million sequence reads per sample to the mouse genome (GRCm38/mm10). Comparing to wild type RAW 264.7 cells, 237 genes were up-regulated and 181 genes were down-regulated in Hnrnpul1-/- cells. At 10 h following LPS stimulation, 341 genes were up-regulated and 288 genes were down-regulated in Hnrnpul1-/- cells. Genes were pre-ranked according to log2FoldChange(KO/WT) followed by GSEA and 6 gene sets were significantly enriched. Significantly differential genes were undergone GO analysis (biological process) and biological process including cell-cell adhesion, positive regulation of cell activation and regulation of response to external stimulus were enriched. Conclusions: Lacking Hnrnpul1 promotes the expression of inflammatory cytokines in LPS stimulated RAW 264.7 cells.

Project description:As obligate parasites, viruses need to navigate a variety of cellular regulatory systems while infecting and replicating in the host cell. Post-transcriptional modifications have recently emerged as an important layer of regulation of viral RNA function. For example, our lab and others have shown that the RNA modification N6-methyladenosine (m6A) can enhance the replication of multiple viruses in cis, including Human Immunodeficiency virus 1 (HIV-1), Influenza A virus, SV40 and Kaposi's sarcoma-associated herpesvirus (KSHV). Recent reports have revealed the presence of another RNA modification, N4-acetylcytidine (ac4C) on cellular mRNAs and have shown that ac4C can enhance mRNA stability and translation. Here, we demonstrate that ac4C is present at multiple sites on HIV-1 mRNAs and on the viral genomic RNA. Through ac4C RNA immunoprecipitation (RNA-IP) and RNA-seq, we found ac4C on HIV-1 mRNAs as well as the virion genomic RNA, with ac4C sites in the coding regions of the pol, env, nef genes, and the trans-activation response (TAR) hairpin. Phenotypically, we observe that increasing the expression level of the ac4C acetyltransferase NAT10 leads to an increase in viral replication that is dependent on the RNA binding and enzymatic domains of NAT10. Moreover, both CRISPR-depletion of NAT10 (ΔNAT10) and treatment with the small molecule NAT10 inhibitor Remodelin, diminishes HIV-1 replication in T cells. Lastly, silent mutations introduced to prevent ac4C deposition on the viral genome indeed diminished HIV-1 replication. Our data suggest that HIV-1 has evolved to incorporate ac4C in essential viral gene coding regions and regulatory RNA structures, and that NAT10-dependent ac4C addition enhances HIV-1 replication.

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.
