For example, precision medicine depends on molecular measurements and data analysis per patient. Data analyses supporting medical decisions must be standardized and performed consistently across patients. While perhaps not life-threatening, data analyses in basic research have become increasingly complex. RNA-seq data, for example, entails a multi-step analysis ranging from quality assessment of the measurements to statistical analyses. Workflow management systems (WFMS) enable the development of data analysis workflows (WF), their reproduction, and their application to datasets of the same type. However, far more than a hundred WFMS are available, and there is no way to convert data analysis WFs among WFMS. Therefore, the initial choice of a WFMS is important as it entails a lock-in to the system. The reach in their particular field (number of citations) can be used as a proxy for selecting a WFMS, but of the about 25 WFMS we mention in this work, at least 5 have a large reach in scientific data analysis. Hence other criteria are needed to delineate among WFMS. By extracting such criteria from selected studies concerning WFMS and adding additional criteria, we arrived at five critical criteria: reproducibility, reusability, FAIRness, versioning support, and security. Another five criteria (providing a graphical user interface, WF flexibility, WF scalability, WF shareability, and computational transparency) we deemed important but not critical for the assessment of WFMS. We applied the criteria to the most cited WFMS in PubMed and found none that support all criteria. We hope that suggesting these criteria will spark a discussion on what features are important for WFMS in scientific data analysis and may lead to developing WFMS that fulfill such criteria.","PeriodicalId":73617,"journal":{"name":"Journal of bioinformatics and systems biology : Open access","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69367943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The performance of novoRNABreak is demonstrated by a comprehensive set of experiments using synthetic data generated based on genome reference, as well as real RNA-seq data from breast cancer and prostate cancer samples.

Clinicopathologic and mRNA expression data and treatment information of 140 patients identified with stage I/II PDAC who underwent pancreaticoduodenectomy were obtained from the Cancer Genome Atlas data set. Our bioinformatic analysis showed that higher CDK1, CDK2, CDK4, or CDK6 expression was associated with a shorter median survival of the early-stage PDAC patients. Of note, in the low-proliferating pancreatic cancer group, CDKs expressions were significantly associated with proteins functioning in apoptosis, metastasis, immunity, or stemness. Among the low-proliferating PDAC, higher expression of CDK1 was associated with the shorter survival of patients, suggesting that CDK1 may regulate PDAC progression through cell cycle-independent mechanisms. Our experimental data showed that CDK1 knockdown/inhibition significantly suppressed the expression levels of AHR and POU5F1, two critical proteins functioning in cancer cell metastasis and stemness, in low-proliferating, but not in high-proliferating pancreatic cancer cells.

To fill this gap, we developed a novel computational approach called SMS to de novo reconstruct bacterial Strain genomes in Multiple Samples. Tested on 702 simulated and 195 experimental datasets, SMS reliably identified the strain number, abundance, and polymorphisms.

We leverage domain knowledge and statistical methods to effectively eliminate various sources of contaminants for identification of RGC types and subtypes. We show that our end-to-end computational pipeline improves the accuracy and reliability of single-cell transcriptome profiling of RGCs and enhances the biological interpretations. To show the effectiveness of our pipeline, we use 5,994 RGCs captured from retinas of mouse using Fluidigm technology as a benchmark dataset and compare with widely used quality control tools. Further, we introduce seven candidate F-RGC subtype markers that we identified after applying our introduced pipeline on the benchmark dataset.
