    肝细胞癌(HCC)是一种普遍存在的侵袭性癌症,对早期检测提出了重大挑战。这项研究介绍了用于从血清中分离岩藻糖基化的细胞外囊泡(Fu-EV)的GlyExo-Capture方法。我们使用下一代测序(NGS)分析了88例HCC患者和179例非HCC对照中来自Fu-EV的microRNA(miRNA)谱,并鉴定了5种miRNA(hsa-let-7a,hsa-miR-21,hsa-miR-125a,hsa-miR-200a,和hsa-miR-150)作为HCC诊断的生物标志物。五miRNA小组展示了出色的HCC诊断性能,在194个HCC和412个非HCC对照的组合队列中,灵敏度为0.90,特异性为0.92,显着超过甲胎蛋白(AFP)和des-γ-羧基凝血酶原(DCP)的性能。值得注意的是,miRNA模型对0期和A期早期HCC的召回率分别为85.7%和90.8%,分别,确定88.1%的AFP阴性HCC病例,并有效区分HCC与其他癌症。这项研究提供了高通量,快速,和早期肝癌检测的非侵入性方法。
    Hepatocellular carcinoma (HCC) is a prevalent and aggressive cancer that presents significant challenges for early detection. This study introduces the GlyExo-Capture method for isolating fucosylated extracellular vesicles (Fu-EVs) from serum. We analyze microRNA (miRNA) profiles from Fu-EVs in 88 HCC patients and 179 non-HCC controls using next-generation sequencing (NGS) and identify five miRNAs (hsa-let-7a, hsa-miR-21, hsa-miR-125a, hsa-miR-200a, and hsa-miR-150) as biomarkers for HCC diagnosis. The five-miRNA panel demonstrates exceptional HCC diagnostic performance, with a sensitivity of 0.90 and specificity of 0.92 in a combined cohort of 194 HCC and 412 non-HCC controls, significantly surpassing the performance of alpha-fetoprotein (AFP) and des-gamma-carboxy prothrombin (DCP). Notably, the miRNA model achieves recall rates of 85.7% and 90.8% for stage 0 and stage A early-stage HCC, respectively, identifies 88.1% of AFP-negative HCC cases, and effectively differentiates HCC from other cancers. This study provides a high-throughput, rapid, and non-invasive approach for early HCC detection.

    UNASSIGNED: Osteoporosis is a major health issue. MicroRNAs (miRNAs) play multiple roles in regulating cell growth and development. High-throughput sequencing technology is widely used nowadays.
    UNASSIGNED: To screen for and validate miRNAs associated with osteoporosis.
    UNASSIGNED: Bone specimens from patients with (n = 3) and without (n = 3) osteoporosis were collected. High-throughput sequencing was used to screen for miRNAs that were then analyzed using volcano maps, Wayne maps, gene ontology (GO) analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Confirmation of the miRNAs was done using qRT-PCR.
    UNASSIGNED: The analysis of sequencing showed that there were 12 miRNAs that were down-regulated and five miRNAs that were upregulated in osteoporosis. GO and KEGG identified these miRNAs as being associated with bone metabolism. The qRT-PCR results showed that miR-140-5p, miR-127-3p, miR-199b-5p, miR-181a-5p, miR-181d-5p, and miR-542-3p exhibited a decrease of 2.27-, 3.00-, 3.48-, 2.67-, 2.41-, and 1.98-fold (all P < 0.05) in osteoporosis compared to controls. Conversely, miR-486-3p and miR-486-5p demonstrated an increase of 2.17- and 3.89-fold (P < 0.05) (all P < 0.05).
    UNASSIGNED: This study utilized high-throughput sequencing to detect miRNAs that were expressed differently in individuals with osteoporosis. In osteoporosis, six miRNAs (miR-140-5p, miR-127-3p, miR-199b-5p, miR-181a-5p, miR-181d-5p, and miR-542) were found to have decreased expression, whereas two miRNAs (miR-486-3p and miR-486-5p) were found to have increased expression. The initial manifestation of various miRNAs might serve as predictive indicators and potentially anticipate the progression of osteoporosis.

    已知胁迫相关蛋白(SAP)在植物对非生物胁迫的反应中起重要作用。本研究使用向日葵基因组数据系统地鉴定了向日葵SAP基因家族的成员。使用生物信息学方法分析向日葵SAP基因家族的基因,在盐和干旱胁迫下通过荧光定量(qRT-PCR)评估基因表达。还对数字进行了综合分析,结构,共线性,以及七个菊科植物和其他八个植物SAP基因家族的系统发育。向日葵基因组被发现有27个SAP基因,分布在14条染色体上。进化分析表明,SAP家族基因可以分为三个亚组。值得注意的是,Annus品种显示第3组的SAP基因扩增。在菊科物种中,C.morifolium表现出最高数量的共线性基因对和系统发育树上最近的距离,表明进化过程中的相对保守性。对基因结构的分析表明,第1组表现出最复杂的基因结构,而第2组和第3组中的大多数HaSAP基因缺乏内含子。启动子分析显示存在与ABA相关的顺式作用元件,表明他们参与应激反应。表达分析表明10个基因(HaSAP1,HaSAP3,HaSAP8,HaSAP10,HaSAP15,HaSAP16,HaSAP21,HaSAP22,HaSAP23和HaSAP26)可能参与向日葵耐盐性。然后使用qRT-PCR检查盐和干旱胁迫下这10个基因的表达,并分析了这10个基因的组织特异性表达模式。HaSAP1,HaSAP21和HaSAP23在盐和干旱胁迫下表现出一致的表达模式,表明这些基因在向日葵的耐盐性和抗旱性中起作用。这项研究的发现强调了SAP基因家族对向日葵耐盐性和抗旱性的重要贡献。
    Stress-associated proteins (SAPs) are known to play an important role in plant responses to abiotic stresses. This study systematically identified members of the sunflower SAP gene family using sunflower genome data. The genes of the sunflower SAP gene family were analyzed using bioinformatic methods, and gene expression was assessed through fluorescence quantification (qRT-PCR) under salt and drought stress. A comprehensive analysis was also performed on the number, structure, collinearity, and phylogeny of seven Compositae species and eight other plant SAP gene families. The sunflower genome was found to have 27 SAP genes, distributed across 14 chromosomes. The evolutionary analysis revealed that the SAP family genes could be divided into three subgroups. Notably, the annuus variety exhibited amplification of the SAP gene for Group 3. Among the Compositae species, C. morifolium demonstrated the highest number of collinearity gene pairs and the closest distance on the phylogenetic tree, suggesting relative conservation in the evolutionary process. An analysis of gene structure revealed that Group 1 exhibited the most complex gene structure, while the majority of HaSAP genes in Group 2 and Group 3 lacked introns. The promoter analysis revealed the presence of cis-acting elements related to ABA, indicating their involvement in stress responses. The expression analysis indicated the potential involvement of 10 genes (HaSAP1, HaSAP3, HaSAP8, HaSAP10, HaSAP15, HaSAP16, HaSAP21, HaSAP22, HaSAP23, and HaSAP26) in sunflower salt tolerance. The expression of these 10 genes were then examined under salt and drought stress using qRT-PCR, and the tissue-specific expression patterns of these 10 genes were also analyzed. HaSAP1, HaSAP21, and HaSAP23 exhibited consistent expression patterns under both salt and drought stress, indicating these genes play a role in both salt tolerance and drought resistance in sunflower. The findings of this study highlight the significant contribution of the SAP gene family to salt tolerance and drought resistance in sunflower.

    背景:热激转录因子(Hsf)是植物抗逆的关键调节因子,在植物应激反应中起关键作用,增长,和发展调控。
    结果:在这项研究中,我们利用生物信息学工具筛选了25个VbHsf成员,它们被命名为VbHsf1-VbHsf25。我们使用生物信息学方法分析序列结构,物理化学性质,保守的图案,系统发育进化,染色体定位,启动子顺式作用元件,共线性,低温胁迫下Hsf热激转录因子家族成员的基因表达。结果表明,大多数Hsf基因包含基序1,基序2和基序3,表明这三个基序在马鞭草的Hsf蛋白序列中高度保守。尽管成员之间的主题删除存在一些差异,域保持高度保守。理论等电点为4.17~9.71,21个成员为不稳定蛋白,其余为稳定蛋白。亚细胞定位预测表明所有成员都位于细胞核中。牛弧菌和拟南芥的Hsf基因家族的系统发育分析表明,牛弧菌的Hsf基因家族可分为三组,其中A组包括17个成员并且C组具有至少两个成员。在Hsf的25名成员中,在7个染色体片段上有1-3个外显子,分布不均。共线性分析表明VbHsf基因家族中存在7对同源基因。Ka/Ks比值小于1,表明VbHsf基因经历了纯化选择压力。此外,发现牛弧菌中的9个基因与拟南芥共线性。启动子分析表明,所有VbHsf基因的启动子都含有与激素和应激相关的各种类型的顺式作用元件。基于RNA-seq数据,进行了6个高表达基因的qRT-PCR分析,发现VbHsf5,VbHsf14,VbHsf17,VbHsf18,VbHsf20和VbHsf21基因在低温处理12h时高表达,24小时后表达下降,其中VbHsf14在低温12小时上调70倍。
    结论:我们的研究可能有助于揭示Hsf在植物发育中的重要作用,并为牛弧菌的进一步分子育种提供见解。
    BACKGROUND: The heat shock transcription factor (Hsf) is a crucial regulator of plant stress resistance, playing a key role in plant stress response, growth, and development regulation.
    RESULTS: In this study, we utilized bioinformatics tools to screen 25 VbHsf members, which were named VbHsf1-VbHsf25. We used bioinformatics methods to analyze the sequence structure, physicochemical properties, conserved motifs, phylogenetic evolution, chromosome localization, promoter cis-acting elements, collinearity, and gene expression of Hsf heat shock transcription factor family members under low-temperature stress. The results revealed that the majority of the Hsf genes contained motif1, motif2, and motif3, signifying that these three motifs were highly conserved in the Hsf protein sequence of Verbena bonariensis. Although there were some variations in motif deletion among the members, the domain remained highly conserved. The theoretical isoelectric point ranged from 4.17 to 9.71, with 21 members being unstable proteins and the remainder being stable proteins. Subcellular localization predictions indicated that all members were located in the nucleus. Phylogenetic analysis of the Hsf gene family in V. bonariensis and Arabidopsis thaliana revealed that the Hsf gene family of V. bonariensis could be categorized into three groups, with group A comprising 17 members and group C having at least two members. Among the 25 Hsf members, there were 1-3 exons located on seven chromosome fragments, which were unevenly distributed. Collinearity analysis demonstrated the presence of seven pairs of homologous genes in the VbHsf gene family. The Ka/Ks ratios were less than one, indicating that the VbHsf gene underwent purification selection pressure. Additionally, nine genes in V. bonariensis were found to have collinearity with A. thaliana. Promoter analysis revealed that the promoters of all VbHsf genes contained various types of cis-acting elements related to hormones and stress. Based on RNA-seq data, qRT-PCR analysis of six highly expressed genes was performed, and it was found that VbHsf5, VbHsf14, VbHsf17, VbHsf18, VbHsf20 and VbHsf21 genes were highly expressed at 12 h of low-temperature treatment, and the expression decreased after 24 h, among which VbHsf14 was up-regulated at 12 h of low-temperature by 70-fold.
    CONCLUSIONS: Our study may help reveal the important roles of Hsf in plant development and show insight for the further molecular breeding of V. bonariensis.

    The CONSTANS-like (COL) gene plays important roles in plant growth, development, and abiotic stress. A total of 15 COL genes are unevenly distributed on eight chromosomes in the potato genome. The amino acid length of the family members was 347-453 aa, the molecular weight was 38.65-49.92 kD, and the isoelectric point was 5.13-6.09. The StCOL family can be divided into three subfamilies by evolutionary tree analysis, with conserved motifs and similar gene structure positions in each subfamily. The analysis of promoter cis-acting elements showed 17 cis-acting elements related to plant hormones, stress, and light response. Collinearity analysis of COL genes of tomato, potato, and Arabidopsis showed that 13 StCOL genes in the different species may have a common ancestor. A total of 10 conserved motifs and six kinds of post-translational modifications in the 15 StCOL proteins were identified. The 15 StCOL genes exhibit a genomic structure consisting of exons and introns, typically ranging from two to four in number. The results showed that 10 genes displayed significant expression across all potato tissues, while the remaining five genes were down-expressed in potato transcriptome data. The quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis exhibited differential expression of 8 StCOL genes in the potato leaves and tubers at different growth stages, as well as 7 StCOL genes under 2°C treatment conditions. These results suggested that the StCOL gene family may play an important role in regulating potato tuberization and responding to cold stress.

    Panax ginseng is a perennial herb with the main active compounds of ginsenosides. Among the reported ginsenosides, ginsenoside Rg_1 not only has a wide range of medicinal functions and abundant content but also is one of the major ginsenoside for the quality evaluation of this herb in the Chinese Pharmacopoeia. The main biosynthesis pathway of ginsenoside Rg_1 in P. ginseng has been clarified, which lays a foundation for the comprehensive and in-depth analysis of the biosynthesis and regulatory mechanism of ginseno-side Rg_1. However, the biosynthesis of ginsenoside Rg_1 is associated with other complex processes involving a variety of regulatory genes and catalyzing enzyme genes, which remain to be studied comprehensively. With the transcriptome data of 344 root samples from 4-year-old P. ginseng plants and their corresponding ginsenoside Rg_1 content obtained in the previous study, this study screened out 217 differentially expressed genes(DEGs) with Rg_1 content changes by DEseq2 analysis in R language. Furthermore, the weighted gene co-expression network analysis(WGCNA) revealed 40 hub genes among the DEGs.Pearsoncorrelation analysis was further perforned to yield 20 candidate genes significantly correlated with ginsenoside Rg_1 content, and these genes were annotated to multiple metabolic processes including primary metabolism and secondary metabolism. Finally, the treatment of P. ginseng adventitious roots with methyl jasmonate indicated that 16 of these genes promoted the biosynthesis of ginsenoside Rg_1 in response to methyl jasmonate induction. Finally, one of the 16 genes was randomly selected to verify the function of the gene by genetic transformation and qRT-PCR and to confirm the rationality of the methodology of this study. The above results lay a foundation for studying the mechanism for regulation on the synthesis of ginsenoside Rg_1 and provide genetic resources for the industrial production of ginsenoside Rg_1.

    进化分析表明,GF14家族是保守的,然而,将GF14与植物高度联系起来的证据有限。在我们的调查中,我们发现了ZmGF14s和与植物高度相关的功能特征基因之间的共表达关系。在共表达网络中,我们鉴定了ZmGF14-3,这是一个与三个玉米品种的株高呈正相关的基因表达,我们推测该基因可能与植物高度发育密切相关。随后,我们从玉米B73自交系中克隆了ZmGF14-3,并在拟南芥中过表达,导致明显矮化的转基因表型。内源性植物激素的测量表明,过表达的拟南芥中赤霉素7(GA7)和吲哚-3-乙酸(IAA)的浓度显着降低,此外,qPCR结果突出表明,与野生型相比,植物高度相关基因的表达水平明显下降,因此,可以认为ZmGF14-3通过与各种植物激素相关基因的相互作用在调节玉米的生长发育中起着关键作用。因此,深入研究ZmGF14-3与这些基因之间的潜在相互作用有望对玉米株高发育的分子机制产生有价值的见解。
    The evolutionary analysis showed that the GF14 family was conserved, however, there was limited evidence linking GF14s to plant height. In our investigations, we discovered a co-expression relationship between ZmGF14s and functionally characterized genes linked to plant height. In the co-expression network, we identified ZmGF14-3, a gene expression exhibiting a positive correlation with plant height in three maize varieties, we postulated that this gene could be intimately linked to plant height development. Subsequently, we cloned ZmGF14-3 from the maize B73 inbred line and overexpressed it in Arabidopsis, resulting in markedly dwarfed transgenic phenotypes. Measurements of endogenous phytohormones disclosed a significant reduction in concentrations of Gibberellic Acid 7 (GA7) and Indole-3-Acetic Acid (IAA) in the overexpressed Arabidopsis, furthermore, qPCR results highlighted a pronounced decrease in the expression levels of plant height-related genes when compared to the wild type, therefore, it is plausible to posit that ZmGF14-3 plays a pivotal role in regulating the growth and development of maize through interactions with various phytohormone-related genes. Thus, delving into the potential interactions between ZmGF14-3 and these genes holds the promise of yielding valuable insights into the molecular mechanisms underpinning plant height development in maize.

    小豆是一种典型的短日植物,是一种重要的粮食作物,由于其高的营养和药用价值而被广泛使用。小豆开花时间受多种环境因素的影响,特别是光周期。调整日长可以诱导小豆的花同步,加速育种过程。在这项研究中,我们使用RNA测序分析来确定不同日长对小豆开花时间相关基因表达和代谢特征的影响。
    \'唐山红小豆\'作为本研究的实验材料,并在2022年采用随机区组设计进行了田间试验,采用三种处理方法:短日诱导期5d(SD-5d),10d(SD-10d),15d(SD-15d)。
    总共鉴定了5,939个差异表达基因(DEGs),其中上调38.09%,下调23.81%。对目标基因进行基因本体论富集分析,以鉴定与光系统I和II相关的常见功能。京都基因百科全书和基因组富集分析确定了涉及天线蛋白和昼夜节律的两种途径。此外,通过蓝光代谢途径下调昼夜节律途径中的基因来促进花序;然而,天线蛋白通过增强光信号的接收和加速电子传输来促进开花。在这两种代谢途径中,SD-5d和SD-15d组之间的DEGs数量最大。8个DEGs的实时逆转录-定量聚合酶链反应分析结果与测序结果一致。因此,测序结果准确可靠,确定了8个基因为小豆苗期短日诱导调控的候选基因。
    短日诱导能够根据昼夜节律下调与开花相关的基因的表达,并上调天线蛋白途径中某些基因的表达。研究结果为研究短日诱导的分子机制提供了理论参考,为今后的功能研究验证调控小豆开花的关键基因提供了多层次信息。
    UNASSIGNED: The adzuki bean is a typical short-day plant and an important grain crop that is widely used due to its high nutritional and medicinal value. The adzuki bean flowering time is affected by multiple environmental factors, particularly the photoperiod. Adjusting the day length can induce flower synchronization in adzuki bean and accelerate the breeding process. In this study, we used RNA sequencing analysis to determine the effects of different day lengths on gene expression and metabolic characteristics related to adzuki bean flowering time.
    UNASSIGNED: \'Tangshan hong xiao dou\' was used as the experimental material in this study and field experiments were conducted in 2022 using a randomized block design with three treatments: short-day induction periods of 5 d (SD-5d), 10 d (SD-10d), and 15 d (SD-15d).
    UNASSIGNED: A total of 5,939 differentially expressed genes (DEGs) were identified, of which 38.09% were up-regulated and 23.81% were down-regulated. Gene ontology enrichment analysis was performed on the target genes to identify common functions related to photosystems I and II. Kyoto Encyclopedia of Genes and Genomes enrichment analysis identified two pathways involved in the antenna protein and circadian rhythm. Furthermore, florescence was promoted by down-regulating genes in the circadian rhythm pathway through the blue light metabolic pathway; whereas, antenna proteins promoted flowering by enhancing the reception of light signals and accelerating electron transport. In these two metabolic pathways, the number of DEGs was the greatest between the SD-5d VS SD-15d groups. Real-time reverse transcription‒quantitative polymerase chain reaction analysis results of eight DEGs were consistent with the sequencing results. Thus, the sequencing results were accurate and reliable and eight genes were identified as candidates for the regulation of short-day induction at the adzuki bean seedling stage.
    UNASSIGNED: Short-day induction was able to down-regulate the expression of genes related to flowering according to the circadian rhythm and up-regulate the expression of certain genes in the antenna protein pathway. The results provide a theoretical reference for the molecular mechanism of short-day induction and multi-level information for future functional studies to verify the key genes regulating adzuki bean flowering.

    这项研究的重点是急性髓系白血病(AML),尽管有多种治疗选择,但5年生存率仍低于30%。最近在靶向治疗方面取得的进展显示出了希望,以最小的毒性导致更好的结果。这些进展强调了发现AML新的诊断和预后靶标的重要性。在这种情况下,作者研究了microRNA-106b-5p(miR-106b-5p)的表达,Rab10mRNA,和Rab10蛋白在外周血和骨髓(BM)样本来自健康个体和AML患者在疾病的不同阶段(初始诊断,复发,和完全缓解)。这项检查旨在确定AML诊断的潜在生物标志物。治疗,和预后。从2021年6月到2022年12月,他们收集了100个BM和外周血样本。采用实时聚合酶链反应(qRT-PCR)检测AML患者BM中miR-106b-5p和Rab10mRNA的相对表达,用ELISA法测定血清中Rab10蛋白的相对表达量。使用R胶带分析最初诊断的患者的染色体核型。qRT-PCR结果显示miR-106b-5p和Rab10mRNA在初次诊断和复发患者中的表达显著高于健康个体和完全缓解者(p<0.001)。他们观察到miR-106b-5p的表达显着降低,Rab10mRNA,完全缓解期患者的BM和外周血中Rab10蛋白(p<0.05),如初始组中5例患者的动态监测所示。此外,他们发现miR-106b-5p的表达与AML患者初始诊断时的白细胞数量密切相关(p<0.05).Spearman相关分析显示miR-106b-5p之间呈正相关,Rab10mRNA,和Rab10蛋白(p<0.05)。受试者工作特征(ROC)曲线分析强调了miR-106b-5p和Rab10蛋白的诊断潜力,这证明了它们在AML诊断中的高准确性(AUC:0.944和0.853;p<0.0001)。此外,Kaplan-Meier生存分析提示这些标志物的较低表达与更好的预后相关(p<0.05)。总之,他们的发现提出miR-106b-5p和Rab10蛋白作为AML的有希望的生物标志物,提供诊断见解,治疗,和预后。
    This study focuses on acute myeloid leukemia (AML), a condition with a 5-year survival rate below 30% despite various treatment options. Recent strides in targeted therapies have shown promise, leading to better outcomes with minimal toxicity. These advances underscore the importance of discovering new diagnostic and prognostic targets for AML. In this context, the authors investigated the expression of microRNA-106b-5p (miR-106b-5p), Rab10 mRNA, and Rab10 proteins in peripheral blood and bone marrow (BM) samples from both healthy individuals and AML patients at different stages of the disease (initial diagnosis, recurrence, and complete remission). This examination aimed to identify potential biomarkers for AML diagnosis, treatment, and prognosis. From June 2021 to December 2022, they collected 100 BM and peripheral blood samples. The relative expression of miR-106b-5p and Rab10 mRNA in the BM of AML patients was measured using Real-time polymerase chain reaction (qRT-PCR), while the relative expression of Rab10 protein in serum was determined using the ELISA method. The chromosomal karyotype of initially diagnosed patients was analyzed using the R tape. The qRT-PCR results revealed that the expression of miR-106b-5p and Rab10 mRNA were significantly higher in patients at initial diagnosis and recurrence compared with healthy individuals and those in complete remission (p < 0.001). They observed a significant reduction in the expression of miR-106b-5p, Rab10 mRNA, and Rab10 protein in the BM and peripheral blood of patients during complete remission (p < 0.05), as demonstrated by dynamic monitoring of five patients in the initial group. Furthermore, they found a close association between the expression of miR-106b-5p and the number of white blood cells at the initial diagnosis in AML patients (p < 0.05). Spearman correlation analysis revealed a positive correlation among miR-106b-5p, Rab10 mRNA, and Rab10 proteins (p < 0.05). The diagnostic potential of miR-106b-5p and Rab10 proteins was underscored by Receiver Operating Characteristic (ROC) curve analysis, which demonstrated their high accuracy in AML diagnosis (AUC: 0.944 and 0.853, respectively; p < 0.0001). Additionally, Kaplan-Meier survival analysis suggested that lower expression of these markers was associated with better prognoses (p < 0.05). In summary, their findings propose miR-106b-5p and Rab10 proteins as promising biomarkers for AML, offering insights for diagnosis, treatment, and prognosis.
