Background: Histone lactylation, a metabolic stress-related histone modification, plays an important role in the regulation of gene expression during M1 macrophage polarization. However, the role of histone lactylation in tumorigenesis remains unclear.

Results: Here, we show histone lactylation is elevated in tumors and is associated with poor prognosis of ocular melanoma. Target correction of aberrant histone lactylation triggers therapeutic efficacy both in vitro and in vivo. Mechanistically, histone lactylation contributes to tumorigenesis by facilitating YTHDF2 expression. Moreover, YTHDF2 recognizes the m6A modified PER1 and TP53 mRNAs and promotes their degradation, which accelerates tumorigenesis of ocular melanoma.

Conclusion: We reveal the oncogenic role of histone lactylation, thereby providing novel therapeutic targets for ocular melanoma therapy. We also bridge histone modifications with RNA modifications, which provides novel understanding of epigenetic regulation in tumorigenesis.

背景:组蛋白乳酸化是一种与代谢应激相关的组蛋白修饰,在M1巨噬细胞极化过程中对基因表达的调控中起着重要作用。然而,组蛋白乳酸化在肿瘤发生中的作用尚不清楚。结果:在这里,我们发现组蛋白乳酸化在肿瘤中升高,并与眼部黑色素瘤的不良预后有关。靶校正异常组蛋白乳酸化触发治疗效果在体外和体内。从机制上讲,组蛋白乳酸化通过促进YTHDF2的表达而促进肿瘤发生。此外,YTHDF2识别m6A修饰的PER1和TP53 mrna并促进其降解,从而加速眼部黑色素瘤的发生。结论:我们揭示了组蛋白乳酸化的致瘤作用,从而为眼部黑色素瘤的治疗提供了新的治疗靶点。我们还在组蛋白修饰和RNA修饰之间架起了桥梁,这为肿瘤发生中的表观遗传调控提供了新的理解。

Background: Most single nucleotide variants (SNVs) occur in noncoding sequence where millions of transcription factor binding sites (TFBS) reside. Here, a comparative analysis of CRISPR-mediated homology-directed repair (HDR) versus the recently reported prime editing 2 (PE2) system was carried out in mice over a TFBS called a CArG box in the Tspan2 promoter.

Results: Quantitative RT-PCR showed loss of Tspan2 mRNA in aorta and bladder, but not heart or brain, of mice homozygous for an HDR-mediated three base pair substitution in the Tspan2 CArG box. Using the same protospacer, mice homozygous for a PE2-mediated single-base substitution in the Tspan2 CArG box displayed similar cell-specific loss of Tspan2 mRNA; expression of an overlapping long noncoding RNA was also nearly abolished in aorta and bladder. Immuno-RNA fluorescence in situ hybridization validated loss of Tspan2 in vascular smooth muscle cells of HDR and PE2 CArG box mutant mice. Targeted sequencing demonstrated variable frequencies of on-target editing in all PE2 and HDR founders. However, whereas no on-target indels were detected in any of the PE2 founders, all HDR founders showed varying levels of on-target indels. Off-target analysis by targeted sequencing revealed mutations in many HDR founders, but none in PE2 founders.

Conclusions: PE2 directs high-fidelity editing of a single base in a TFBS leading to cell-specific loss in expression of an mRNA/long noncoding RNA gene pair. The PE2 platform expands the genome editing toolbox for modeling and correcting relevant noncoding SNVs in the mouse.

背景:大多数单核苷酸变异(SNV)发生在非编码序列中,而这些序列中存在数百万个转录因子结合位点(TFBS)。在此,我们对 CRISPR 介导的同源定向修复(HDR)与最近报道的质粒编辑 2(PE2)系统进行了比较分析:结果:定量 RT-PCR 显示,在 Tspan2 CArG 框中由 HDR 介导的三个碱基对置换的同源小鼠中,主动脉和膀胱中的 Tspan2 mRNA 丢失,但心脏和大脑中的 Tspan2 mRNA 没有丢失。使用相同的原间隔子,Tspan2 CArG 框中 PE2 介导的单碱基替换的同源小鼠也表现出类似的细胞特异性 Tspan2 mRNA 缺失;在主动脉和膀胱中,重叠的长非编码 RNA 的表达也几乎消失。免疫 RNA 荧光原位杂交验证了 HDR 和 PE2 CArG 盒突变小鼠血管平滑肌细胞中 Tspan2 的缺失。靶向测序显示,在所有 PE2 和 HDR 基因中,靶上编辑的频率各不相同。然而,虽然在所有 PE2 基因中都没有检测到靶上嵌合体,但在所有 HDR 基因中都出现了不同程度的靶上嵌合体。通过靶向测序进行的脱靶分析在许多 HDR 基因发现了突变,但在 PE2 基因中没有发现突变:结论:PE2 可对 TFBS 中的一个碱基进行高保真编辑,导致 mRNA/长非编码 RNA 基因对的细胞特异性表达缺失。PE2 平台扩展了基因组编辑工具箱,可用于建模和校正小鼠的相关非编码 SNV。

Here, we develop k -mer substring space decomposition (Kssd), a sketching technique which is significantly faster and more accurate than current sketching methods. We show that it is the only method that can be used for large-scale dataset comparisons at population resolution on simulated and real data. Using Kssd, we prioritize references for all 1,019,179 bacteria whole genome sequencing (WGS) runs from NCBI Sequence Read Archive and find misidentification or contamination in 6164 of these. Additionally, we analyze WGS and exome runs of samples from the 1000 Genomes Project.

Background: Alternative polyadenylation (APA) refers to the regulated selection of polyadenylation sites (PASs) in transcripts, which determines the length of their 3' untranslated regions (3'UTRs). We have recently shown that SRSF3 and SRSF7, two closely related SR proteins, connect APA with mRNA export. The mechanism underlying APA regulation by SRSF3 and SRSF7 remained unknown.

Results: Here we combine iCLIP and 3'-end sequencing and find that SRSF3 and SRSF7 bind upstream of proximal PASs (pPASs), but they exert opposite effects on 3'UTR length. SRSF7 enhances pPAS usage in a concentration-dependent but splicing-independent manner by recruiting the cleavage factor FIP1, generating short 3'UTRs. Protein domains unique to SRSF7, which are absent from SRSF3, contribute to FIP1 recruitment. In contrast, SRSF3 promotes distal PAS (dPAS) usage and hence long 3'UTRs directly by counteracting SRSF7, but also indirectly by maintaining high levels of cleavage factor Im (CFIm) via alternative splicing. Upon SRSF3 depletion, CFIm levels decrease and 3'UTRs are shortened. The indirect SRSF3 targets are particularly sensitive to low CFIm levels, because here CFIm serves a dual function; it enhances dPAS and inhibits pPAS usage by binding immediately downstream and assembling unproductive cleavage complexes, which together promotes long 3'UTRs.

Conclusions: We demonstrate that SRSF3 and SRSF7 are direct modulators of pPAS usage and show how small differences in the domain architecture of SR proteins can confer opposite effects on pPAS regulation.

背景:选择性聚腺苷化(APA)是指转录本中聚腺苷化位点(PASs)的调控选择,它决定了转录本3'非翻译区(3' utr)的长度。我们最近发现,两个密切相关的SR蛋白SRSF3和SRSF7将APA与mRNA的输出联系起来。SRSF3和SRSF7调控APA的机制尚不清楚。结果:本研究结合iCLIP和3’端测序发现,SRSF3和SRSF7结合在近端PASs (pPASs)上游,但对3’utr长度的影响相反。SRSF7通过招募裂解因子FIP1,产生短的3' utr,以浓度依赖但与剪接无关的方式增强了pPAS的使用。SRSF7特有的蛋白结构域参与了FIP1的募集,而SRSF3中没有。相反,SRSF3通过抵消SRSF7直接促进远端PAS (dPAS)的使用,从而促进长3' utr,但也通过选择性剪接间接维持高水平的切割因子Im (CFIm)。SRSF3耗竭后,CFIm水平降低,3' utr缩短。间接的SRSF3靶点对低CFIm水平特别敏感,因为CFIm在这里具有双重功能;它通过直接结合下游和组装非生产性裂解复合物来增强dPAS并抑制pPAS的使用,这些裂解复合物共同促进长3' utr。结论:我们证明SRSF3和SRSF7是pPAS使用的直接调节剂,并表明SR蛋白结构域结构的微小差异如何对pPAS调节产生相反的影响。

Genome-scale metabolic models of microorganisms are powerful frameworks to predict phenotypes from an organism's genotype. While manual reconstructions are laborious, automated reconstructions often fail to recapitulate known metabolic processes. Here we present gapseq ( https://github.com/jotech/gapseq ), a new tool to predict metabolic pathways and automatically reconstruct microbial metabolic models using a curated reaction database and a novel gap-filling algorithm. On the basis of scientific literature and experimental data for 14,931 bacterial phenotypes, we demonstrate that gapseq outperforms state-of-the-art tools in predicting enzyme activity, carbon source utilisation, fermentation products, and metabolic interactions within microbial communities.

Identification of pathogenic variants in cancer genes using base editing screens with editing efficiency correction. 利用具有编辑效率校正功能的碱基编辑筛选确定癌症基因中的致病变异。

Background: Millions of nucleotide variants are identified through cancer genome sequencing and it is clinically important to identify the pathogenic variants among them. By introducing base substitutions at guide RNA target regions in the genome, CRISPR-Cas9-based base editors provide the possibility for evaluating a large number of variants in their genomic context. However, the variability in editing efficiency and the complexity of outcome mapping are two existing problems for assigning guide RNA effects to variants in base editing screens.

Results: To improve the identification of pathogenic variants, we develop a framework to combine base editing screens with sgRNA efficiency and outcome mapping. We apply the method to evaluate more than 9000 variants across all the exons of BRCA1 and BRCA2 genes. Our efficiency-corrected scoring model identifies 910 loss-of-function variants for BRCA1/2, including 151 variants in the noncoding part of the genes such as the 5' untranslated regions. Many of them are identified in cancer patients and are reported as "benign/likely benign" or "variants of uncertain significance" by clinicians. Our data suggest a need to re-evaluate their clinical significance, which may be helpful for risk assessment and treatment of breast and ovarian cancer.

Conclusions: Our results suggest that base editing screens with efficiency correction is a powerful strategy to identify pathogenic variants in a high-throughput manner. Applying this strategy to assess variants in both coding and noncoding regions of the genome could have a direct impact on the interpretation of cancer variants.

背景:通过癌症基因组测序确定了数百万个核苷酸变异,而确定其中的致病变异具有重要的临床意义。基于 CRISPR-Cas9 的碱基编辑器通过在基因组中的引导 RNA 靶区引入碱基替换,为评估基因组上下文中的大量变异提供了可能。然而,编辑效率的可变性和结果图谱的复杂性是目前在碱基编辑筛选中将向导 RNA 的效应分配给变异体的两个问题:为了更好地识别致病变异,我们开发了一个框架,将碱基编辑筛选与 sgRNA 效率和结果图谱相结合。我们应用该方法评估了 BRCA1 和 BRCA2 基因所有外显子中的 9000 多个变异。我们的效率校正评分模型确定了 BRCA1/2 的 910 个功能缺失变异,包括基因非编码部分(如 5' 非翻译区)的 151 个变异。其中许多变异是在癌症患者中发现的,临床医生将其报告为 "良性/可能良性 "或 "意义不确定的变异"。我们的数据表明,有必要重新评估它们的临床意义,这可能有助于乳腺癌和卵巢癌的风险评估和治疗:我们的研究结果表明,带有效率校正的碱基编辑筛选是一种以高通量方式鉴定致病变异的强大策略。应用这种策略评估基因组编码区和非编码区的变异可能会对癌症变异的解释产生直接影响。

Background: A-to-I RNA editing diversifies the transcriptome and has multiple downstream functional effects. Genetic variation contributes to RNA editing variability between individuals and has the potential to impact phenotypic variability.

Results: We analyze matched genetic and transcriptomic data in 49 tissues across 437 individuals to identify RNA editing events that are associated with genetic variation. Using an RNA editing quantitative trait loci (edQTL) mapping approach, we identify 3117 unique RNA editing events associated with a cis genetic polymorphism. Fourteen percent of these edQTL events are also associated with genetic variation in their gene expression. A subset of these events are associated with genome-wide association study signals of complex traits or diseases. We determine that tissue-specific levels of ADAR and ADARB1 are able to explain a subset of tissue-specific edQTL events. We find that certain microRNAs are able to differentiate between the edited and unedited isoforms of their targets. Furthermore, microRNAs can generate an expression quantitative trait loci (eQTL) signal from an edQTL locus by microRNA-mediated transcript degradation in an editing-specific manner. By integrative analyses of edQTL, eQTL, and microRNA expression profiles, we computationally discover and experimentally validate edQTL-microRNA pairs for which the microRNA may generate an eQTL signal from an edQTL locus in a tissue-specific manner.

Conclusions: Our work suggests a mechanism in which RNA editing variability can influence the phenotypes of complex traits and diseases by altering the stability and steady-state level of critical RNA molecules.

背景:A 到 I RNA 编辑使转录组多样化,并具有多种下游功能效应。遗传变异导致个体间 RNA 编辑的变异,并有可能影响表型的变异:我们分析了 437 个个体 49 种组织中匹配的遗传和转录组数据,以确定与遗传变异相关的 RNA 编辑事件。利用RNA编辑定量性状位点(edQTL)绘图方法,我们确定了3117个与顺式遗传多态性相关的独特RNA编辑事件。其中 14% 的 edQTL 事件还与基因表达的遗传变异有关。这些事件的一部分与复杂性状或疾病的全基因组关联研究信号有关。我们确定,组织特异性水平的 ADAR 和 ADARB1 能够解释一部分组织特异性 edQTL 事件。我们发现,某些 microRNA 能够区分其靶标的编辑异构体和未编辑异构体。此外,microRNA还能以编辑特异性的方式,通过microRNA介导的转录本降解,从edQTL位点产生表达定量性状位点(eQTL)信号。通过对edQTL、eQTL和microRNA表达谱的综合分析,我们通过计算发现并通过实验验证了edQTL-microRNA对,其中microRNA可能以组织特异性的方式从edQTL基因座产生eQTL信号:我们的工作提出了一种机制,即 RNA 编辑变异可通过改变关键 RNA 分子的稳定性和稳态水平来影响复杂性状和疾病的表型。

Spatial transcriptomic and proteomic technologies have provided new opportunities to investigate cells in their native microenvironment. Here we present Giotto, a comprehensive and open-source toolbox for spatial data analysis and visualization. The analysis module provides end-to-end analysis by implementing a wide range of algorithms for characterizing tissue composition, spatial expression patterns, and cellular interactions. Furthermore, single-cell RNAseq data can be integrated for spatial cell-type enrichment analysis. The visualization module allows users to interactively visualize analysis outputs and imaging features. To demonstrate its general applicability, we apply Giotto to a wide range of datasets encompassing diverse technologies and platforms.

Controlling quality of next-generation sequencing (NGS) data files is a necessary but complex task. To address this problem, we statistically characterize common NGS quality features and develop a novel quality control procedure involving tree-based and deep learning classification algorithms. Predictive models, validated on internal and external functional genomics datasets, are to some extent generalizable to data from unseen species. The derived statistical guidelines and predictive models represent a valuable resource for users of NGS data to better understand quality issues and perform automatic quality control. Our guidelines and software are available at https://github.com/salbrec/seqQscorer .
