    中枢神经系统(CNS)和免疫系统共同协调细胞功能,共享共同的发展机制。免疫相关分子对大脑发育有影响,挑战传统观点的大脑免疫特权。慢性炎症在阿尔茨海默病(AD)的病理生理学中发挥关键作用,压力增加导致疾病进展,并可能加剧现有症状。在这项研究中,从AD患者和健康个体的选定RNA测序(RNA-seq)数据中获得了最重要的基因特征,并进行了功能分析和生物学解释,包括网络和路径富集分析。报告了重要证据,如免疫系统反应和抗原过程的富集,以及T细胞介导的细胞毒性和内源性和外源性肽抗原的正调控,从而表明神经炎症和免疫反应参与疾病进展。这些发现提示了外周免疫环境的免疫浸润紊乱,从强烈参与AD发展的分子角度探索关键生物过程提供了新的挑战。
    The central nervous system (CNS) and the immune system collectively coordinate cellular functionalities, sharing common developmental mechanisms. Immunity-related molecules exert an influence on brain development, challenging the conventional view of the brain as immune-privileged. Chronic inflammation emerges as a key player in the pathophysiology of Alzheimer\'s disease (AD), with increased stress contributing to the disease progression and potentially exacerbating existing symptoms. In this study, the most significant gene signatures from selected RNA-sequencing (RNA-seq) data from AD patients and healthy individuals were obtained and a functional analysis and biological interpretation was conducted, including network and pathway enrichment analysis. Important evidence was reported, such as enrichment in immune system responses and antigen processes, as well as positive regulation of T-cell mediated cytotoxicity and endogenous and exogenous peptide antigen, thus indicating neuroinflammation and immune response participation in disease progression. These findings suggest a disturbance in the immune infiltration of the peripheral immune environment, providing new challenges to explore key biological processes from a molecular perspective that strongly participate in AD development.

    SenecavirusA(SVA)是一种引起猪水泡病的新兴病毒,临床上与其他高后果的水疱性疾病难以区分。该病毒属于小牛科Senecavirus属。它的基因组是一个积极意义,单链RNA,长度约为7,300nt,具有3\'聚(A)尾,但没有5\'端封端结构。SVA可以在不同的细胞中有效繁殖,包括一些非猪来源的细胞系。先前在我们的实验室中使用反向遗传学从其cDNA克隆中拯救了野生型SVA。在本研究中,用传代-5SVA接种BSR-T7/5细胞系。接种后12小时,独立收集SVA感染和未感染的细胞用于比较转录组学分析。结果显示共628个差异表达基因,包括565个上调和63个下调,表明SVA感染显著刺激细胞中的转录起始。GO和KEGG富集分析表明SVA对细胞中免疫相关途径发挥多种作用。此外,RNA测序数据进行了其他深入分析,比如单核苷酸多态性,转录因子,和蛋白质-蛋白质相互作用。本研究,随着我们以前的蛋白质组学和代谢组学研究,提供了对SVA与其宿主之间相互作用的多组学洞察。
    Senecavirus A (SVA) is an emerging virus that causes the vesicular disease in pigs, clinically indistinguishable from other high consequence vesicular diseases. This virus belongs to the genus Senecavirus in the family Picornaviridae. Its genome is a positive-sense, single-stranded RNA, approximately 7,300 nt in length, with a 3\' poly(A) tail but without 5\'-end capped structure. SVA can efficiently propagate in different cells, including some non-pig-derived cell lines. A wild-type SVA was previously rescued from its cDNA clone using reverse genetics in our laboratory. In the present study, the BSR-T7/5 cell line was inoculated with the passage-5 SVA. At 12 h post-inoculation, SVA-infected and non-infected cells were independently collected for the analysis on comparative transcriptomics. The results totally showed 628 differentially expressed genes, including 565 upregulated and 63 downregulated ones, suggesting that SVA infection significantly stimulated the transcription initiation in cells. GO and KEGG enrichment analyses demonstrated that SVA exerted multiple effects on immunity-related pathways in cells. Furthermore, the RNA sequencing data were subjected to other in-depth analyses, such as the single-nucleotide polymorphism, transcription factors, and protein-protein interactions. The present study, along with our previous proteomics and metabolomics researches, provides a multi-omics insight into the interaction between SVA and its hosts.

    籽粒相关性状在水稻种植中至关重要,影响产量和消费者偏好。这些特征的复杂遗传,涉及促成其表达的多个等位基因,对育种提出了挑战。为了应对这些挑战,我们利用35,286个高质量单核苷酸多态性(SNPs)进行了多基因座全基因组关联研究(ML-GWAS).我们的研究利用了一个关联小组,该小组包括来自东北核心组的483个水稻基因型和从印度各个地区收集的地方品种组。鉴定了40个数量性状核苷酸(QTNs),与四个籽粒相关性状相关:籽粒长度(GL),晶粒宽度(GW),谷物香气(阿罗),和长宽比(LWR)。值得注意的是,使用两种ML-GWAS方法同时鉴定了16种QTNs,分布在多个染色体上。在16个显著的QTNs附近发现了近258个基因。基因注释研究表明,这些基因中有60个在特定组织中表现出升高的表达水平,并且与影响谷物品质的途径有关。基因本体论(GO),特质本体论(TO),和富集分析确定了60个富含相关GO术语的候选基因(CGs)。其中,LOC_Os05g06470、LOC_Os06g06080、LOC_Os08g43470和LOC_Os03g53110被确认为GL的主要贡献者,GW,阿罗,和LWR。来自QTNs和CGs的见解阐明了水稻性状调控和遗传联系,为未来的研究提供潜在的目标。
    Grain-related traits are pivotal in rice cultivation, influencing yield and consumer preference. The complex inheritance of these traits, involving multiple alleles contributing to their expression, poses challenges in breeding. To address these challenges, a multi-locus genome-wide association study (ML-GWAS) utilizing 35,286 high-quality single-nucleotide polymorphisms (SNPs) was conducted. Our study utilized an association panel comprising 483 rice genotypes sourced from a northeast core set and a landraces set collected from various regions in India. Forty quantitative trait nucleotides (QTNs) were identified, associated with four grain-related traits: grain length (GL), grain width (GW), grain aroma (Aro), and length-width ratio (LWR). Notably, 16 QTNs were simultaneously identified using two ML-GWAS methods, distributed across multiple chromosomes. Nearly 258 genes were found near the 16 significant QTNs. Gene annotation study revealed that sixty of these genes exhibited elevated expression levels in specific tissues and were implicated in pathways influencing grain quality. Gene ontology (GO), trait ontology (TO), and enrichment analysis pinpointed 60 candidate genes (CGs) enriched in relevant GO terms. Among them, LOC_Os05g06470, LOC_Os06g06080, LOC_Os08g43470, and LOC_Os03g53110 were confirmed as key contributors to GL, GW, Aro, and LWR. Insights from QTNs and CGs illuminate rice trait regulation and genetic connections, offering potential targets for future studies.

    目的:这项研究的主要目的是深入研究长链非编码RNA(lncRNA)SPACA6P-AS在乳腺癌(BC)发展中的参与,专注于它的表达模式,与临床病理特征相关,对预后的影响,以及它的分子和免疫学意义。
    方法:利用来自TCGA数据库的1083例BC患者的RNA测序数据进行生物信息学分析。通过构建生存曲线对SPACA6P-AS进行功能探索,GO和KEGG富集分析,和单样本基因集富集分析(ssGSEA)。此外,通过体外细胞实验和体内裸鼠模型实验验证了其功能。
    结果:SPACA6P-AS在BC组织中的表达水平显着增加(p<0.001),并显示出与不良预后密切相关(总生存期HR=1.616,无进展间隔HR=1.40,疾病特异性生存期HR=1.54)。富集分析表明,SPACA6P-AS可以影响蛋白酶调节等生物学功能,内肽酶抑制剂活性,味觉受体活性,味觉转导,和年轻途径的成熟型糖尿病。ssGSEA分析显示SPACA6P-AS表达与树突状细胞和中性粒细胞等免疫细胞浸润呈负相关,而与中枢记忆T细胞和辅助性T细胞2呈正相关。体外和体内实验结果表明,沉默SPACA6P-AS显著抑制细胞增殖,迁移,和BC细胞的侵袭能力。体外实验还强调了具有沉默的SPACA6P-AS的树突状细胞在促进自体CD3+T细胞增殖和细胞因子分泌方面表现出增强的能力。这些发现阐明了SPACA6P-AS在公元前的潜在多方面作用,包括其可能参与调节肿瘤微环境中的免疫细胞浸润。
    结论:BC中lncRNASPACA6P-AS的高表达与不良预后密切相关,可能通过影响特定的生物学过程促进肿瘤进展。信号通路,和免疫微环境。SPACA6P-AS的调节作用将其定位为用于BC诊断和干预的治疗方法的前瞻性生物标志物和靶标。
    OBJECTIVE: The primary objective of this investigation is to delve into the involvement of the long noncoding RNA (lncRNA) SPACA6P-AS in breast cancer (BC) development, focusing on its expression pattern, association with clinical-pathological features, impact on prognosis, as well as its molecular and immunological implications.
    METHODS: Bioinformatics analysis was conducted utilizing RNA sequencing data of 1083 BC patients from the TCGA database. Functional exploration of SPACA6P-AS was carried out through the construction of survival curves, GO and KEGG enrichment analysis, and single-sample gene set enrichment analysis (ssGSEA). Furthermore, its functionality was validated through in vitro cell experiments and in vivo nude mouse model experiments.
    RESULTS: SPACA6P-AS showed a remarkable increase in expression levels in BC tissues (p < 0.001) and demonstrated a close relationship to poor prognosis (overall survival HR = 1.616, progression-free interval HR = 1.40, disease-specific survival HR = 1.54). Enrichment analysis revealed that SPACA6P-AS could impact biological functions such as protease regulation, endopeptidase inhibitor activity, taste receptor activity, taste transduction, and maturity-onset diabetes of the young pathway. ssGSEA analysis indicated a negative correlation between SPACA6P-AS expression and immune cell infiltration like dendritic cells and neutrophils, while a positive correlation was observed with central memory T cells and T helper 2 cells. Results from in vitro and in vivo experiments illustrated that silencing SPACA6P-AS significantly inhibited the proliferation, migration, and invasion capabilities of BC cells. In vitro experiments also highlighted that dendritic cells with silenced SPACA6P-AS exhibited enhanced capabilities in promoting the proliferation of autologous CD3 + T cells and cytokine secretion. These discoveries elucidate the potential multifaceted roles of SPACA6P-AS in BC, including its potential involvement in modulating immune cell infiltration in the tumor microenvironment.
    CONCLUSIONS: The high expression of lncRNA SPACA6P-AS in BC is closely linked to poor prognosis and may facilitate tumor progression by influencing specific biological processes, signaling pathways, and the immune microenvironment. The regulatory role of SPACA6P-AS positions it as a prospective biomarker and target for therapeutic approaches for BC diagnosis and intervention.

    据报道,肿瘤免疫微环境在肿瘤进展中起着至关重要的作用。然而,免疫细胞相关基因(IRGs)在食管鳞状细胞癌(ESCC)中的作用机制尚不清楚。
    TCGA-ESCC,通过公共数据库获得GSE23400、GSE26886、GSE75241和GSE196756数据集。首先,通过差异表达分析筛选出ESCC与GSE23400、GSE26886和GSE75241对照样品之间的差异表达基因(DEGs),并确定了重叠的DEG。应用GSE196756的单细胞转录组数据来探索可能参与ESCC调控的免疫细胞。然后,应用加权基因共表达网络分析筛选IRGs。接下来,差异表达的IRGs(DE-IRGs)通过重叠的IRGs和DEGs鉴定,并被纳入单变量考克斯,最小绝对收缩和选择运算符,和多变量Cox来获取预后相关基因,根据中位风险评分将ESCC样本分为高/低风险组.最后,分析预后模型在免疫治疗中的作用。
    通过重叠GSE26886中的3,915个DEG、GSE23400中的459个DEG和GSE75241中的1,641个DEG,总共产生了248个DEG。单细胞分析发现B细胞,树突状细胞,单核细胞,中性粒细胞,自然杀伤细胞,和T细胞参与ESCC的发展。此外,MEred,MEblack,MEpink,MEblue和MEbrown模块被认为是关键模块,因为它们与免疫细胞亚型的相关性最高。通过在关键模块中获取DEG和基因的交叉,总共产生了154个DE-IRG。此外,CTSC,ALOX12和RMND5B在ESCC中被鉴定为预后相关基因。显然,高危人群的排除和TIDE评分明显低于另一组,表明高危人群对免疫疗法的反应更敏感.
    通过生物信息学分析,我们确定了一个由IRGs(CTSC,ALOX12和RMND5B)在ESCC中,为ESCC的治疗和预后相关研究提供新的思路。
    UNASSIGNED: It has been reported that tumor immune microenvironment performs a vital role in tumor progress. However, acting mechanism of immune cell related genes (IRGs) in esophageal squamous cell carcinoma (ESCC) is uncertain.
    UNASSIGNED: TCGA-ESCC, GSE23400, GSE26886, GSE75241, and GSE196756 datasets were gained via public databases. First, differentially expressed genes (DEGs) between ESCC and control samples from GSE23400, GSE26886, and GSE75241 were screened out by differential expression analysis, and overlapping DEGs were identified. Single-cell transcriptome data of GSE196756 were applied to explore immune cells that might be involved in regulation of ESCC. Then, weighted gene co-expression network analysis was applied to screen IRGs. Next, differentially expressed IRGs (DE-IRGs) were identified by overlapping IRGs and DEGs, and were incorporated into univariate Cox, least absolute shrinkage and selection operator, and multivariate Cox to acquire prognosis-related genes, and ESCC samples were grouped into high-/low-risk groups on the basis of median risk score. Finally, the role of prognosis model in immunotherapy was analyzed.
    UNASSIGNED: Totally 248 DEGs were yielded by overlapping 3,915 DEGs in GSE26886, 459 DEGs in GSE23400, and 1,641 DEGs in GSE75241. Single-cell analysis found that B cells, dendritic cells, monocytes, neutrophils, natural killer cells, and T cells were involved in ESCC development. Besides, MEred, MEblack, MEpink, MEblue and MEbrown modules were considered as key modules because of their highest correlations with immune cell subtypes. A total of 154 DE-IRGs were yielded by taking intersection of DEGs and genes in key modules. Moreover, CTSC, ALOX12, and RMND5B were identified as prognosis-related genes in ESCC. Obviously, Exclusion and TIDE scores were notably lower in high-risk group than in the other one, indicating that high-risk group was more responsive to immunotherapy.
    UNASSIGNED: Through bioinformatic analysis, we identified a prognosis model consisting of IRGs (CTSC, ALOX12, and RMND5B) in ESCC, providing new ideas for studies related to treatment and prognosis of ESCC.

    背景:突触结合蛋白11(SYT11)在神经元囊泡运输和胞吐中起关键作用。然而,没有针对各种癌症的独立预后研究.在这项研究中,我们旨在总结SYT11在各种肿瘤类型中的临床意义和分子前景。
    方法:使用几个可用的公共数据库,我们研究了SYT11在不同肿瘤类型中的异常表达及其与预后的潜在临床关联,甲基化分析,免疫浸润,基因富集分析,和蛋白质-蛋白质相互作用分析,并确定了共同的途径。
    结果:TCGA和基因型组织表达(GTEx)显示SYT11在肿瘤和相应的正常组织中广泛表达。生存分析显示SYT11表达与7种癌症类型的预后相关。此外,SYT11mRNA表达不受启动子甲基化的影响,但受某些miRNA调控,与癌症患者预后相关。体外实验进一步验证了SYT11与miR-19a-3p在人大肠癌中的表达呈负相关,肺,和肾癌细胞系。此外,SYT11异常表达与免疫浸润显著相关。通路富集分析显示SYT11的生物学和分子过程与网格蛋白介导的内吞作用有关,RhoGTPase信号传导,和细胞运动相关的功能。
    结论:我们的结果为SYT11在各种癌症类型中的作用提供了清晰的理解,并提示SYT11可能具有预后和临床意义。
    BACKGROUND: Synaptotagmin 11 (SYT11) plays a pivotal role in neuronal vesicular trafficking and exocytosis. However, no independent prognostic studies have focused on various cancers. In this study, we aimed to summarize the clinical significance and molecular landscape of SYT11 in various tumor types.
    METHODS: Using several available public databases, we investigated abnormal SYT11 expression in different tumor types and its potential clinical association with prognosis, methylation profiling, immune infiltration, gene enrichment analysis, and protein-protein interaction analysis, and identified common pathways.
    RESULTS: TCGA and Genotype-Tissue Expression (GTEx) showed that SYT11 was widely expressed across tumor and corresponding normal tissues. Survival analysis showed that SYT11 expression correlated with the prognosis of seven cancer types. Additionally, SYT11 mRNA expression was not affected by promoter methylation, but regulated by certain miRNAs and associated with cancer patient prognosis. In vitro experiments further verified a negative correlation between the expression of SYT11 and miR-19a-3p in human colorectal, lung, and renal cancer cell lines. Moreover, aberrant SYT11 expression was significantly associated with immune infiltration. Pathway enrichment analysis revealed that the biological and molecular processes of SYT11 were related to clathrin-mediated endocytosis, Rho GTPase signaling, and cell motility-related functions.
    CONCLUSIONS: Our results provide a clear understanding of the role of SYT11 in various cancer types and suggest that SYT11 may be of prognostic and clinical significance.
