Objectives: This study examined prescription NSAIDs as one of the leading predictors of incident depression and assessed the direction of the association among older cancer survivors with osteoarthritis.

Methods: This study used a retrospective cohort (N = 14, 992) of older adults with incident cancer (breast, prostate, colorectal cancers, or non-Hodgkin's lymphoma) and osteoarthritis. We used the longitudinal data from the linked Surveillance, Epidemiology, and End Results -Medicare data for the study period from 2006 through 2016, with a 12-month baseline and 12-month follow-up period. Cumulative NSAIDs days was assessed during the baseline period and incident depression was assessed during the follow-up period. An eXtreme Gradient Boosting (XGBoost) model was built with 10-fold repeated stratified cross-validation and hyperparameter tuning using the training dataset. The final model selected from the training data demonstrated high performance (Accuracy: 0.82, Recall: 0.75, Precision: 0.75) when applied to the test data. SHapley Additive exPlanations (SHAP) was used to interpret the output from the XGBoost model.

Results: Over 50% of the study cohort had at least one prescption of NSAIDs. Nearly 13% of the cohort were diagnosed with incident depression, with the rates ranging between 7.4% for prostate cancer and 17.0% for colorectal cancer. The highest incident depression rate of 25% was observed at 90 and 120 cumulative NSAIDs days thresholds. Cumulative NSAIDs days was the sixth leading predictor of incident depression among older adults with OA and cancer. Age, education, care fragmentation, polypharmacy, and zip code level poverty were the top 5 predictors of incident depression.

Conclusion: Overall, 1 in 8 older adults with cancer and OA were diagnosed with incident depression. Cumulative NSAIDs days was the sixth leading predictor with an overall positive association with incident depression. However, the association was complex and varied by the cumulative NSAIDs days.

目的:本研究考察了处方非甾体抗炎药作为抑郁症发生的主要预测因素之一,并评估了老年骨关节炎癌症幸存者之间的关联方向。方法:本研究采用回顾性队列研究(N = 14,992),纳入了发生癌症(乳腺癌、前列腺癌、结直肠癌或非霍奇金淋巴瘤)和骨关节炎的老年人。我们使用了2006年至2016年研究期间相关的监测、流行病学和最终结果-医疗保险数据的纵向数据,包括12个月的基线和12个月的随访期。在基线期评估累积的非甾体抗炎药天数,在随访期评估抑郁事件。利用训练数据集,通过10倍重复分层交叉验证和超参数调优,建立了极端梯度增强(XGBoost)模型。从训练数据中选择的最终模型在应用于测试数据时表现出高性能(准确率:0.82,召回率:0.75,精度:0.75)。SHapley加性解释(SHAP)用于解释XGBoost模型的输出。结果:超过50%的研究队列至少有一种非甾体抗炎药处方。近13%的人被诊断为偶发性抑郁症,前列腺癌的发病率为7.4%,结肠直肠癌的发病率为17.0%。在nsaid累计用药90和120天时观察到最高的抑郁发生率为25%。累计服用非甾体抗炎药天数是老年OA和癌症患者发生抑郁的第六大预测因子。年龄、教育程度、护理碎片化、多种药物治疗和邮政编码水平贫困是事件抑郁症的前5个预测因素。结论:总体而言,每8名患有癌症和OA的老年人中就有1人被诊断为偶发性抑郁症。累计服用非甾体抗炎药天数是与抑郁事件总体正相关的第六大预测因子。然而,随着非甾体抗炎药使用日数的增加,这种关联变得复杂和多样。

Hepatocellular carcinoma (HCC) is one of the most fatal cancers in the world. There is an urgent need to understand the molecular background of HCC to facilitate the identification of biomarkers and discover effective therapeutic targets. Published transcriptomic studies have reported a large number of genes that are individually significant for HCC. However, reliable biomarkers remain to be determined. In this study, built on max-linear competing risk factor models, we developed a machine learning analytical framework to analyze transcriptomic data to identify the most miniature set of differentially expressed genes (DEGs). By analyzing 9 public whole-transcriptome datasets (containing 1184 HCC samples and 672 nontumor controls), we identified 5 critical differentially expressed genes (DEGs) (ie, CCDC107, CXCL12, GIGYF1, GMNN, and IFFO1) between HCC and control samples. The classifiers built on these 5 DEGs reached nearly perfect performance in identification of HCC. The performance of the 5 DEGs was further validated in a US Caucasian cohort that we collected (containing 17 HCC with paired nontumor tissue). The conceptual advance of our work lies in modeling gene-gene interactions and correcting batch effect in the analytic framework. The classifiers built on the 5 DEGs demonstrated clear signature patterns for HCC. The results are interpretable, robust, and reproducible across diverse cohorts/populations with various disease etiologies, indicating the 5 DEGs are intrinsic variables that can describe the overall features of HCC at the genomic level. The analytical framework applied in this study may pave a new way for improving transcriptome profiling analysis of human cancers.
肝细胞癌(HCC)是世界上最致命的癌症之一。迫切需要了解HCC的分子背景,以促进生物标志物的鉴定和发现有效的治疗靶点。已发表的转录组学研究报告了大量对HCC具有显著个体意义的基因。然而,可靠的生物标志物仍有待确定。在这项研究中,基于最大线性竞争风险因素模型,我们开发了一个机器学习分析框架来分析转录组学数据,以识别最微小的差异表达基因(deg)集。通过分析9个公开的全转录组数据集(包含1184个HCC样本和672个非肿瘤对照组),我们确定了HCC和对照样本之间的5个关键差异表达基因(deg)(即CCDC107、CXCL12、GIGYF1、GMNN和IFFO1)。基于这5个deg构建的分类器在鉴别HCC方面达到了近乎完美的性能。我们收集的美国白种人队列(包含17个配对的非肿瘤组织的HCC)进一步验证了5个DEGs的性能。我们工作的概念上的进步在于建立基因-基因相互作用的模型,并在分析框架中纠正批效应。基于5个deg构建的分类器显示出HCC的明确特征模式。研究结果在不同疾病病因的不同队列/人群中具有可解释性、稳健性和可重复性,表明5个deg是内在变量,可以在基因组水平上描述HCC的总体特征。本研究应用的分析框架可能为改进人类癌症转录组分析开辟新的途径。

Epidemiologic evidence for the association of cholesterol and breast cancer is inconsistent. Several factors may contribute to this inconsistency, including limited sample sizes, confounding effects of antihyperlipidemic treatment, age, and body mass index, and the assumption that the association follows a simple linear function. Here, we aimed to address these factors by combining visualization and quantification a large-scale contemporary electronic health record database (the All of Us Research Program). We find clear visual and quantitative evidence that breast cancer is strongly, positively, and near-linearly associated with total cholesterol and low-density lipoprotein cholesterol, but not associated with triglycerides. The association of breast cancer with high-density lipoprotein cholesterol was non-linear and age dependent. Standardized odds ratios were 2.12 (95% confidence interval 1.9-2.48), P = 5.6 × 10-31 for total cholesterol; 1.99 (1.75-2.26), P = 2.6 × 10-26 for low-density lipoprotein cholesterol; 1.69 (1.3-2.2), P = 9.0 × 10-5 for high-density lipoprotein cholesterol at age < 56; and 0.65 (0.55-0.78), P = 1.2 × 10-6 for high-density lipoprotein cholesterol at age ⩾ 56. The inclusion of the lipid levels measured after antihyperlipidemic treatment in the analysis results in erroneous associations. We demonstrate that the use of the logistic regression without inspecting risk variable linearity and accounting for confounding effects may lead to inconsistent results.

关于胆固醇和乳腺癌之间关系的流行病学证据并不一致。有几个因素可能导致这种不一致,包括有限的样本量、抗高脂血症治疗的混杂效应、年龄和体重指数,以及这种关联遵循简单线性函数的假设。在这里,我们的目标是通过结合可视化和量化大型现代电子健康记录数据库(我们所有人研究计划)来解决这些因素。我们发现清晰的视觉和定量证据表明,乳腺癌与总胆固醇和低密度脂蛋白胆固醇呈强烈、积极和近线性相关,但与甘油三酯无关。乳腺癌与高密度脂蛋白胆固醇的关系是非线性和年龄相关的。总胆固醇的标准化优势比为2.12(95%可信区间为1.9-2.48),P = 5.6 × 10-31;低密度脂蛋白胆固醇1.99 (1.75-2.26),P = 2.6 × 10-26;1.69(1.3-2.2),年龄时高密度脂蛋白胆固醇的P = 9.0 × 10-5,年龄大于或等于56岁时高密度脂蛋白胆固醇的P = 1.2 × 10-6。在分析中纳入抗高脂血症治疗后测量的脂质水平会导致错误的关联。我们证明,使用逻辑回归而不检查风险变量线性和考虑混杂效应可能导致不一致的结果。

Using a decision support system (DSS) that classifies various cancers provides support to the clinicians/researchers to make better decisions that can aid in early cancer diagnosis, thereby reducing chances of incorrect disease diagnosis. Thus, this work aimed at designing a classification model that can predict accurately for 5 different cancer types comprising of 20 cancer exomes, using the mutations identified from whole exome cancer analysis. Initially, a basic model was designed using supervised machine learning classification algorithms such as K-nearest neighbor (KNN), support vector machine (SVM), decision tree, naïve bayes and random forest (RF), among which decision tree and random forest performed better in terms of preliminary model accuracy. However, output predictions were incorrect due to less training scores. Thus, 16 essential features were then selected for model improvement using 2 approaches. All imbalanced datasets were balanced using SMOTE. In the first approach, all features from 20 cancer exome datasets were trained and models were designed using decision tree and random forest. Balanced datasets for decision tree model showed an accuracy of 77%, while with the RF model, the accuracy improved to 82% where all 5 cancer types were predicted correctly. Area under the curve for RF model was closer to 1, than decision tree model. In the second approach, all 15 datasets were trained, while 5 were tested. However, only 2 cancer types were predicted correctly. To cross validate RF model, Matthew's correlation co-efficient (MCC) test was performed. For method 1, the MCC test and MCC cross validation was found to be 0.7796 and 0.9356 respectively. Likewise, for second approach, MCC was observed to be 0.9365, corroborating the accuracy of the designed model. The model was successfully deployed using Streamlit as a web application for easy use. This study presents insights for allowing easy cancer classifications.

使用对各种癌症进行分类的决策支持系统(DSS)为临床医生/研究人员提供支持,帮助他们做出更好的决策,从而有助于早期癌症诊断,从而减少错误疾病诊断的机会。因此,本工作旨在设计一个分类模型,该模型可以使用从全外显子组癌症分析中鉴定的突变,准确预测由20个癌症外显子组组成的5种不同癌症类型。首先,使用k近邻(KNN)、支持向量机(SVM)、决策树、naïve贝叶斯和随机森林(RF)等监督机器学习分类算法设计基本模型,其中决策树和随机森林在模型初步精度上表现较好。然而,由于训练分数较少,输出预测是不正确的。因此,然后选择16个基本特征,使用2种方法进行模型改进。使用SMOTE对所有不平衡数据集进行平衡。在第一种方法中,对来自20个癌症外显子组数据集的所有特征进行训练,并使用决策树和随机森林设计模型。决策树模型的平衡数据集显示准确率为77%,而RF模型的准确率提高到82%,其中所有5种癌症类型都被正确预测。与决策树模型相比,射频模型的曲线下面积更接近于1。在第二种方法中,所有15个数据集都进行了训练,而5个数据集进行了测试。然而,只有两种癌症类型预测正确。为了交叉验证RF模型,采用Matthew’s相关系数检验(MCC)。方法1的MCC检验和MCC交叉验证分别为0.7796和0.9356。同样,对于第二种方法,观察到MCC为0.9365,证实了设计模型的准确性。该模型已成功部署,使用Streamlit作为web应用程序,方便使用。这项研究为简化癌症分类提供了见解。

The present study was the first comprehensive investigation of genetic mutation and expression levels of the p53 signaling genes in cutaneous melanoma through various genetic databases providing large datasets. The mutational landscape of p53 and its signaling genes was higher than expected, with TP53 followed by CDKN2A being the most mutated gene in cutaneous melanoma. Furthermore, the expression analysis showed that TP53, MDM2, CDKN2A, and TP53BP1 were overexpressed, while MDM4 and CDKN2B were under-expressed in cutaneous melanoma. Overall, TCGA data revealed that among all the other p53 signaling proteins, CDKN2A was significantly higher in both sun and non-sun-exposed healthy tissues than in melanoma. Likewise, MDM4 and TP53BP1 expressions were markedly greater in non-sun-exposed healthy tissues compared to other groups. However, CDKN2B expression was higher in the sun-exposed healthy tissues than in other tissues. In addition, various genes were expressed significantly differently among males and females. In addition, CDKN2A was highly expressed in the SK-MEL-30 skin cancer cell line, whereas, Immune cell type expression analysis revealed that the MDM4 was highly expressed in naïve B-cells. Furthermore, all six genes were significantly overexpressed in extraordinarily overweight or obese tumor tissues compared to healthy tissues. MDM2 expression and tumor stage were closely related. There were differences in gene expression across patient age groups and positive nodal status. TP53 showed a positive correlation with B cells, MDM2 with CD8+T cells, macrophages and neutrophils, and MDM4 with neutrophils. CDKN2A/B had a non-significant correlation with all six types of immune cells. However, TP53BP1 was positively correlated with all five types of immune cells except B cells. Only TP53, MDM2, and CDKN2A had a role in cutaneous melanoma-specific tumor immunity. All TP53 and its regulating genes may be predictive for prognosis. The results of the present study need to be validated through future screening, in vivo, and in vitro studies.

Introduction: In the era of big data, gene-set pathway analyses derived from multi-omics are exceptionally powerful. When preparing and analyzing high-dimensional multi-omics data, the installation process and programing skills required to use existing tools can be challenging. This is especially the case for those who are not familiar with coding. In addition, implementation with high performance computing solutions is required to run these tools efficiently.

Methods: We introduce an automatic multi-omics pathway workflow, a point and click graphical user interface to Multivariate Single Sample Gene Set Analysis (MOGSA), hosted on the Cancer Genomics Cloud by Seven Bridges Genomics. This workflow leverages the combination of different tools to perform data preparation for each given data types, dimensionality reduction, and MOGSA pathway analysis. The Omics data includes copy number alteration, transcriptomics data, proteomics and phosphoproteomics data. We have also provided an additional workflow to help with downloading data from The Cancer Genome Atlas and Clinical Proteomic Tumor Analysis Consortium and preprocessing these data to be used for this multi-omics pathway workflow.

Results: The main outputs of this workflow are the distinct pathways for subgroups of interest provided by users, which are displayed in heatmaps if identified. In addition to this, graphs and tables are provided to users for reviewing.

Conclusion: Multi-omics Pathway Workflow requires no coding experience. Users can bring their own data or download and preprocess public datasets from The Cancer Genome Atlas and Clinical Proteomic Tumor Analysis Consortium using our additional workflow based on the samples of interest. Distinct overactivated or deactivated pathways for groups of interest can be found. This useful information is important in effective therapeutic targeting.

导读:在大数据时代,多组学衍生的基因集通路分析异常强大。在准备和分析高维多组学数据时,使用现有工具所需的安装过程和编程技能可能具有挑战性。对于那些不熟悉编码的人来说尤其如此。此外,需要使用高性能计算解决方案来实现高效运行这些工具。方法:我们引入了一个自动的多组学通路工作流,一个点按式图形用户界面,用于多变量单样本基因集分析(MOGSA),该分析由Seven Bridges Genomics托管在Cancer Genomics Cloud上。该工作流利用不同工具的组合来为每个给定的数据类型、降维和MOGSA路径分析执行数据准备。组学数据包括拷贝数改变、转录组学数据、蛋白质组学和磷蛋白质组学数据。我们还提供了一个额外的工作流程来帮助从癌症基因组图谱和临床蛋白质组学肿瘤分析协会下载数据,并对这些数据进行预处理,以用于多组学途径工作流程。结果:此工作流的主要输出是用户提供的感兴趣的子组的不同路径,如果确定,则显示在热图中。除此之外,还提供图形和表格供用户查看。结论:Multi-omics Pathway Workflow不需要编码经验。用户可以带来他们自己的数据,或者下载和预处理来自癌症基因组图谱和临床蛋白质组学肿瘤分析联盟的公共数据集,使用我们基于感兴趣样本的额外工作流程。对于感兴趣的群体,可以发现不同的过度激活或不激活的途径。这些有用的信息对于有效的靶向治疗非常重要。

Genome instability of cancer cells translates into increased entropy and lower information processing capacity, leading to metabolic reprograming toward higher energy states, presumed to be aligned with a cancer growth imperative. Dubbed as the cell adaptive fitness, the proposition postulates that the coupling between cell signaling and metabolism constrains cancer evolutionary dynamics along trajectories privileged by the maintenance of metabolic sufficiency for survival. In particular, the conjecture postulates that clonal expansion becomes restricted when genetic alterations induce a sufficiently high level of disorder, that is, high entropy, in the regulatory signaling network, abrogating as a result the ability of cancer cells to successfully replicate, leading to a stage of clonal stagnation. The proposition is analyzed in the context of an in-silico model of tumor evolutionary dynamics to illustrate how cell-inherent adaptive fitness may predictably constrain clonal evolution of tumors, which would have significant implications for the design of adaptive cancer therapies.
癌细胞基因组的不稳定性转化为熵的增加和信息处理能力的降低,导致代谢重编程向更高的能量状态发展,据推测这与癌症生长的必要性是一致的。这一命题被称为细胞适应性适应度,它假设细胞信号传导和代谢之间的耦合限制了癌症沿着维持生存所需的代谢充足性的轨迹进化动力学。特别是,该猜想假设,当基因改变在调节信号网络中引起足够高水平的紊乱(即高熵)时,克隆扩展受到限制,从而取消癌细胞成功复制的能力,导致克隆停滞阶段。该命题在肿瘤进化动力学的计算机模型的背景下进行了分析,以说明细胞固有的适应适应度如何可预测地约束肿瘤的克隆进化,这将对适应性癌症治疗的设计具有重要意义。

Abnormal miRNA expression has been evidenced to be directly linked to HCC initiation and progression. This study was designed to detect possible prognostic, diagnostic, and/or therapeutic miRNAs for HCC using computational analysis of miRNAs expression. Methods: miRNA expression datasets meta-analysis was performed using the YM500v2 server to compare miRNA expression in normal and cancerous liver tissues. The most significant differentially regulated miRNAs in our study undergone target gene analysis using the mirWalk tool to obtain their validated and predicted targets. The combinatorial target prediction tool; miRror Suite was used to obtain the commonly regulated target genes. Functional enrichment analysis was performed on the resulting targets using the DAVID tool. A network was constructed based on interactions among microRNAs, their targets, and transcription factors. Hub nodes and gatekeepers were identified using network topological analysis. Further, we performed patient data survival analysis based on low and high expression of identified hubs and gatekeeper nodes, patients were stratified into low and high survival probability groups. Results: Using the meta-analysis option in the YM500v2 server, 34 miRNAs were found to be significantly differentially regulated (P-value ⩽ .05); 5 miRNAs were down-regulated while 29 were up-regulated. The validated and predicted target genes for each miRNA, as well as the combinatorially predicted targets, were obtained. DAVID enrichment analysis resulted in several important cellular functions that are directly related to the main cancer hallmarks. Among these functions are focal adhesion, cell cycle, PI3K-Akt signaling, insulin signaling, Ras and MAPK signaling pathways. Several hub genes and gatekeepers were found that could serve as potential drug targets for hepatocellular carcinoma. POU2F1 and PPARA showed a significant difference between low and high survival probabilities (P-value ⩽ .05) in HCC patients. Our study sheds light on important biomarker miRNAs for hepatocellular carcinoma along with their target genes and their regulated functions.

Osteosarcoma (OS) is the most common primary cancer in the skeletal system, characterized by a high incidence of lung metastasis, local recurrence and death. Systemic treatment of this aggressive cancer has not improved significantly since the introduction of chemotherapy regimens, underscoring a critical need for new treatment strategies. TRAIL receptors have long been proposed to be therapeutic targets for cancer treatment, but their role in osteosarcoma remains unclear. In this study, we investigated the expression profile of four TRAIL receptors in human OS cells using total RNA-seq and single-cell RNA-seq (scRNA-seq). The results revealed that TNFRSF10B and TNFRSF10D but not TNFRSF10A and TNFRSF10C are differentially expressed in human OS cells as compared to normal cells. At the single cell level by scRNA-seq analyses, TNFRSF10B, TNFRSF10D, TNFRSF10A and TNFRSF10C are most abundantly expressed in endothelial cells of OS tissues among nine distinct cell clusters. Notably, in osteoblastic OS cells, TNFRSF10B is most abundantly expressed, followed by TNFRSF10D, TNFRSF10A and TNFRSF10C. Similarly, in an OS cell line U2-OS using RNA-seq, TNFRSF10B is most abundantly expressed, followed by TNFRSF10D, TNFRSF10A and TNFRSF10C. According to the TARGET online database, poor patient outcomes were associated with low expression of TNFRSF10C. These results could provide a new perspective to design novel therapeutic targets of TRAIL receptors for the diagnosis, prognosis and treatment of OS and other cancers.

骨肉瘤(Osteosarcoma, OS)是骨骼系统中最常见的原发肿瘤,其特点是肺转移、局部复发和死亡的发生率高。自从引入化疗方案以来,这种侵袭性癌症的全身治疗并没有显著改善,这强调了对新治疗策略的迫切需要。TRAIL受体长期以来被认为是癌症治疗的靶点,但其在骨肉瘤中的作用尚不清楚。在这项研究中,我们使用总RNA-seq和单细胞RNA-seq (scRNA-seq)研究了四种TRAIL受体在人OS细胞中的表达谱。结果显示,与正常细胞相比,TNFRSF10B和TNFRSF10D在人OS细胞中存在差异表达,而TNFRSF10A和TNFRSF10C不存在差异表达。在单细胞水平上,通过scRNA-seq分析,在9个不同的细胞簇中,TNFRSF10B、TNFRSF10D、TNFRSF10A和TNFRSF10C在OS组织内皮细胞中表达量最高。值得注意的是,在成骨OS细胞中,TNFRSF10B的表达量最高,其次是TNFRSF10D、TNFRSF10A和TNFRSF10C。同样,在使用RNA-seq的OS细胞系U2-OS中,TNFRSF10B的表达量最高,其次是TNFRSF10D、TNFRSF10A和TNFRSF10C。根据TARGET在线数据库,不良的患者预后与TNFRSF10C的低表达有关。这些结果可以为设计新的TRAIL受体治疗靶点为OS等肿瘤的诊断、预后和治疗提供新的视角。
