PathogenTrack and Yeskit: tools for identifying intracellular pathogens from single-cell RNA-sequencing

《医学前沿(英文)》 2022年 第16卷 第2期   页码 251-262 doi: 10.1007/s11684-021-0915-9

摘要: Pathogenic microbes can induce cellular dysfunction, immune response, and cause infectious disease and other diseases including cancers. However, the cellular distributions of pathogens and their impact on host cells remain rarely explored due to the limited methods. Taking advantage of single-cell RNA-sequencing (scRNA-seq) analysis, we can assess the transcriptomic features at the single-cell level. Still, the tools used to interpret pathogens (such as viruses, bacteria, and fungi) at the single-cell level remain to be explored. Here, we introduced PathogenTrack, a python-based computational pipeline that uses unmapped scRNA-seq data to identify intracellular pathogens at the single-cell level. In addition, we established an R package named Yeskit to import, integrate, analyze, and interpret pathogen abundance and transcriptomic features in host cells. Robustness of these tools has been tested on various real and simulated scRNA-seq datasets. PathogenTrack is competitive to the state-of-the-art tools such as Viral-Track, and the first tools for identifying bacteria at the single-cell level. Using the raw data of bronchoalveolar lavage fluid samples (BALF) from COVID-19 patients in the SRA database, we found the SARS-CoV-2 virus exists in multiple cell types including epithelial cells and macrophages. SARS-CoV-2-positive neutrophils showed increased expression of genes related to type I interferon pathway and antigen presenting module. Additionally, we observed the Haemophilus parahaemolyticus in some macrophage and epithelial cells, indicating a co-infection of the bacterium in some severe cases of COVID-19. The PathogenTrack pipeline and the Yeskit package are publicly available at GitHub.

Distinct immune escape and microenvironment between RG-like and pri-OPC-like glioma revealed by single-cellRNA-seq analysis

《医学前沿(英文)》 doi: 10.1007/s11684-023-1017-7

摘要: The association of neurogenesis and gliogenesis with glioma remains unclear. By conducting single-cell RNA-seq analyses on 26 gliomas, we reported their classification into primitive oligodendrocyte precursor cell (pri-OPC)-like and radial glia (RG)-like tumors and validated it in a public cohort and TCGA glioma. The RG-like tumors exhibited wild-type isocitrate dehydrogenase and tended to carry EGFR mutations, and the pri-OPC-like ones were prone to carrying TP53 mutations. Tumor subclones only in pri-OPC-like tumors showed substantially down-regulated MHC-I genes, suggesting their distinct immune evasion programs. Furthermore, the two subgroups appeared to extensively modulate glioma-infiltrating lymphocytes in distinct manners. Some specific genes not expressed in normal immune cells were found in glioma-infiltrating lymphocytes. For example, glial/glioma stem cell markers OLIG1/PTPRZ1 and B cell-specific receptors IGLC2/IGKC were expressed in pri-OPC-like and RG-like glioma-infiltrating lymphocytes, respectively. Their expression was positively correlated with those of immune checkpoint genes (e.g., LGALS3) and poor survivals as validated by the increased expression of LGALS3 upon IGKC overexpression in Jurkat cells. This finding indicated a potential inhibitory role in tumor-infiltrating lymphocytes and could provide a new way of cancer immune evasion.

Distinct mononuclear diploid cardiac subpopulation with minimal cellcell communications persists in

摘要: A small proportion of mononuclear diploid cardiomyocytes (MNDCMs), with regeneration potential, could persist in adult mammalian heart. However, the heterogeneity of MNDCMs and changes during development remains to be illuminated. To this end, 12 645 cardiac cells were generated from embryonic day 17.5 and postnatal days 2 and 8 mice by single-cell RNA sequencing. Three cardiac developmental paths were identified: two switching to cardiomyocytes (CM) maturation with close CM–fibroblast (FB) communications and one maintaining MNDCM status with least CM–FB communications. Proliferative MNDCMs having interactions with macrophages and non-proliferative MNDCMs (non-pMNDCMs) with minimal cell–cell communications were identified in the third path. The non-pMNDCMs possessed distinct properties: the lowest mitochondrial metabolisms, the highest glycolysis, and high expression of Myl4 and Tnni1. Single-nucleus RNA sequencing and immunohistochemical staining further proved that the Myl4+Tnni1+ MNDCMs persisted in embryonic and adult hearts. These MNDCMs were mapped to the heart by integrating the spatial and single-cell transcriptomic data. In conclusion, a novel non-pMNDCM subpopulation with minimal cell–cell communications was unveiled, highlighting the importance of microenvironment contribution to CM fate during maturation. These findings could improve the understanding of MNDCM heterogeneity and cardiac development, thus providing new clues for approaches to effective cardiac regeneration.

摘要: Oocyte cryopreservation is widely used for clinical and social reasons. Previous studies have demonstrated that conventional slow-freezing cryopreservation procedures, but not storage time, can alter the gene expression profiles of frozen oocytes. Whether vitrification procedures and the related frozen storage durations have any effects on the transcriptomes of human metaphase II oocytes remain unknown. Four women (30–32 years old) who had undergone IVF treatment were recruited for this study. RNA-Seq profiles of 3 fresh oocytes and 13 surviving vitrified-thawed oocytes (3, 3, 4, and 3 oocytes were cryostored for 1, 2, 3, and 12 months) were analyzed at a single-cell resolution. A total of 1987 genes were differentially expressed in the 13 vitrified-thawed oocytes. However, no differentially expressed genes were found between any two groups among the 1-, 2-, 3-, and 12-month storage groups. Further analysis revealed that the aberrant genes in the vitrified oocytes were closely related to oogenesis and development. Our findings indicated that the effects of vitrification on the transcriptomes of mature human oocytes are induced by the procedure itself, suggesting that long-term cryostorage of human oocytes is safe.

摘要:

It has been known that, the novel coronavirus, 2019-nCoV, which is considered similar to SARS-CoV and originated from Wuhan (China), invades human cells via the receptor angiotensin converting enzyme II (ACE2). Moreover, lung cells that have ACE2 expression may be the main target cells during 2019-nCoV infection. However, some patients also exhibit non-respiratory symptoms, such as kidney failure, implying that 2019-nCoV could also invade other organs. To construct a risk map of different human organs, we analyzed the single-cell RNA sequencing (scRNA-seq) datasets derived from major human physiological systems, including the respiratory, cardiovascular, digestive, and urinary systems. Through scRNA-seq data analyses, we identified the organs at risk, such as lung, heart, esophagus, kidney, bladder, and ileum, and located specific cell types (i.e., type II alveolar cells (AT2), myocardial cells, proximal tubule cells of the kidney, ileum and esophagus epithelial cells, and bladder urothelial cells), which are vulnerable to 2019-nCoV infection. Based on the findings, we constructed a risk map indicating the vulnerability of different organs to 2019-nCoV infection. This study may provide potential clues for further investigation of the pathogenesis and route of 2019-nCoV infection.

摘要: Graphene oxide (GO) has been increasingly utilized in the fields of food, biomedicine, environment and other fields because of its benign biocompatible. We encapsulated two kinds of GO with different sizes on yeast cells with the assistance of polyelectrolytes poly (styrene sulfonic acid) sodium salt (PSS) and polyglutamic acid (PGA) (termed as Y@GO). The result does not show a significant difference between the properties of the two types of Y@GO (namely Y@GO1 and Y@GO2). The encapsulation layers are optimized as Yeast/PGA/PSS/PGA/GO/PGA/PSS based on the morphology, dispersity, colony-forming unit, and zeta potential. The encapsulation of GO increases the roughness of the yeast. It is proved that the Y@GO increases the survival time and enhance the activity of yeast cells. The GO shell improves the resistance of yeast cells against pH and salt stresses and extends the storage time of yeast cells.

摘要:

笔者从长期回顾的角度阐述了对人工智能(AI)/数据科学与生物医学之间关系的看法。随着新技术的不断出现,现代生物医学的发展持续加速。由于所有生命系统基本上都受其自身DNA中信息的支配,因此信息科学对生物医学的研究具有特别重要的意义。与物理学不同,在生物学中没有发现(或很少有)主导定律。因此,在生物学中,“数据到知识”方法很重要。人工智能在历史上一直应用于生物医学,最近的新闻表明,基于人工智能的方法在国际蛋白质结构预测竞争中获得了最佳性能,这可能被视为该领域的另一个里程碑。类似的方法可能有助于解决基因组序列解释中的问题,如确定患者基因组中的癌症驱动突变。最近,新一代测序(NGS)的爆炸性发展已产生大量数据,并且这种趋势将加速。NGS不仅用于“读取”DNA序列,而且还用于在单细胞水平上获得各种类型的信息。这些数据可以视为气候模拟中的网格数据点。数据科学和人工智能对于这些数据的综合解释/模拟都将变得至关重要,并将在未来的精密医学中起主导作用。

BULKED SEGREGANT RNA SEQUENCING (BSR-SEQ) IDENTIFIES A NOVEL ALLELE ASSOCIATED WITH WEEPING TRAITS IN

《农业科学与工程前沿(英文)》 2021年 第8卷 第2期

摘要:

Weeping species are used both as ornamental plants and for breeding dwarf plant types. However, exploration of casual genes controlling weeping traits is rather limited. Here, we identified individuals with contrasting phenotypes from an F1 bi-parental mapping population of Prunus mume which was developed from a cross between the upright cultivar ‘Liuban’ and the weeping cultivar ‘Fentai Chuizhi’. Bulked segregant RNA sequencing was used and five QTLs on Chromosome 7 were identified. The Pm024074(PmUGT72B3) allele, belonging to the UDP-glycosyltransferase superfamily containing the coniferyl-alcohol glucosyltransferase domain, was identified in a genomic region overlapping with a previously identified QTL, and had a synonymous transition of T66(upright) to C (weeping) in the coding sequence and a 470-bp deletion in the promoter region. Pm024074 had exceptionally high expression in buds and stems of weeping P. mume. Weighted correlation network analysis indicates that genes neighboring Pm024074 were significantly associated with plant architecture. In addition, a reliable single nucleotide polymorphism marker was developed based on the variation in the Pm024074 gene, providing precise marker-assisted breeding for weeping traits. This study provides insights into the genetic mechanism governing the weeping trait in P. mume, and indicates potential applications for the manipulation of tree architecture.

摘要:

了解重症新型冠状病毒肺炎(COVID-19)患者单核细胞的免疫学特征(包括与纤维化相关的特征)对了解疾病的重症化机制和阻止疾病恶化至关重要。本研究共纳入7名COVID-19患者(包括3名重症/危重症患者和4名普通型患者)和6名健康对照者。采集7名COVID-19患者不同疾病时期外周血样本,包括重症/危重症时期血样3例,轻症时期血样4例,康复期血样7例。将以上血样和6例健康对照者血样进行单细胞转录组测序分析。本研究发现在COVID-19重症/危重症时期,单核细胞发生显著变化。单核细胞在外周血单个核细胞中占比增加,多样性却显著降低。同时本研究发现两个新的COVID-19重症疾病特异性单核细胞亚群:Mono 0和Mono 5。这两个亚群表达amphiregulin(AREG)、epiregulin(EREG)和细胞因子基因IL-18,KEGG分析显示富集的ErbB信号通路,这两个亚群可能具有促纤维化和促炎的特征。进一步分析发现Mono 0和Mono 5发生代谢改变,包括糖酵解/糖异生的增加和HIF-1信号通路的增加。本研究同时发现一个疾病重症前期取得的样本显示出与重症/危重症时期样本相似的单核细胞UMAP图谱。本研究发现了两种新的COVID-19重症疾病特异性单核细胞亚群,可作为重症COVID-19的潜在预测因子和治疗靶点。

《医学前沿(英文)》 2008年 第2卷 第4期   页码 374-379 doi: 10.1007/s11684-008-0072-4

摘要: Expression of DNA methyltransferase 1 (DNMT1), which plays an important role on aberrantly methylated CpG in the promoter regions of tumor suppressor genes (TSGs), is higher in bladder cancer cells than in normal bladder cells. Therefore, its overexpression is closely related to tumor formation. In this study, the eukaryotic vector pshRNA-DNMT1 was constructed and transfected into T24 cells. Levels of DNMT1 mRNA and protein were detected by reverse transcription-polymerase chain reaction (RT-PCR) and western blot. Relative to the blank control at the 24th, 48th and 72nd hour after transfection of pshRNA-DNMT1, the inhibitory rates of DNMT1 mRNA levels in T24 cells were 28.44%, 52.48%, 70.91%, respectively. Those of DNMT1 proteins were 24.27%, 57.79%, and 77.74%, respectively. Proliferation and apoptosis were assayed by MTT and flow cytometry with Annexin-V-FITC/PI staining. The growth inhibition rates of pshRNA-DNMT1 at the 24th, 48th and 72nd hour after transfection of pshRNA-DNMT1 were (4.34 ± 0.76)%, (9.87 ± 1.54)% and (13.78 ± 1.93)%, respectively. There were statistically significant differences between pshRNA-DNMT1 and the control blank at each time points ( < 0.01); 24, 48 and 72 hours after T24 cells were transfected by pshRNA-DNMT1, the apoptosis rates of pshRNA-DNMT1 were (3.87 ± 0.81)%, (8.69 ± 1.23)% and (11.46 ± 1.24)%, respectively ( < 0.01 blank control). Based on this case, our conclusion is that the recombinant plasmid pshRNA-DNMT1 can silence the expression of gene DNMT1 mRNA and protein effectively, and to some extent, it also can inhibit the proliferation of bladder cancer cell and promote the cellular apoptosis.

摘要: X-ray crystallography is a powerful strategy for 3-D structure determination of macromolecules, such as nucleic acids and protein-nucleic acid complexes. However, the crystallization and phase determination are the major bottle-neck problems in crystallography. Recently we have successfully developed synthesis and strategy of selenium-derivatized nucleic acids (SeNA) for nucleic acid crystallography. SeNA might not only provide the rational strategies to solve the phase determination problem, but also offer a potential strategy to explore crystallization solutions.

摘要: Congenital heart disease (CHD) is the most common birth defect worldwide. Long non-coding RNAs (lncRNAs) have been implicated in many diseases. However, their involvement in CHD is not well understood. This study aimed to investigate the role of dysregulated lncRNAs in CHD. We used Gene Expression Omnibus data mining, bioinformatics analysis, and analysis of clinical tissue samples and observed that the novel lncRNA SAP30-2:1 with unknown function was significantly downregulated in damaged cardiac tissues from patients with CHD. Knockdown of lncRNA SAP30-2:1 inhibited the proliferation of human embryonic kidney and AC16 cells and decreased the expression of heart and neural crest derivatives expressed 2 (HAND2). Moreover, lncRNA SAP30-2:1 was associated with HAND2 by RNA immunoprecipitation. Overall, these results suggest that lncRNA SAP30-2:1 may be involved in heart development through affecting cell proliferation via targeting HAND2 and may thus represent a novel therapeutic target for CHD.

摘要:

Mature T-cell lymphoid malignancies comprise a group of heterogeneous diseases that vary in clinicopathological features, biological behavior, treatment response, and prognosis. Bone marrow (BM) infiltration is more commonly present in mature T-cell lymphoid malignancies compared with their B-cell counterparts and hence important for differential diagnosis. In this study, clinical characteristics and prognostic factors were analyzed in 225 patients with mature T-cell lymphoid malignancies treated in a single institution. These included 29 cases of T-cell lymphoproliferative disorders (T-LPD, all with BM infiltration) and 196 cases of T-/natural-killer-cell lymphoma (T/NKCL, 56 with BM infiltration and 140 without BM infiltration). The estimated 5-year overall survival (OS) rates of T-LPD and T/NKCL were 96.6% and 37.3%, respectively. T-LPD patients were less likely to exhibit poor performance status, advanced disease stage, presence of B symptoms, or abnormal level of serum β-2 microglobulin. With similar pathological characteristics, T/NKCL patients with BM infiltration showed significantly lower response rates and shorter OS than those without BM infiltration (P = 0.0264 and P<0.0001, respectively). Multivariate analysis indicated that poor performance status, advanced disease stage, elevated serum lactate dehydrogenase level, and BM involvement were independent unfavorable prognostic factors. The Glasgow Prognostic Score may be more efficient than the International Prognostic Index in predicting disease outcome in T/NKCL. In conclusion, clinical characteristics may be useful in more effectively stratifying patients with mature T-cell lymphoid malignancies.
