Conclusions: doi: 10.1371/journal.pone.0185607. b Summary and statistics test of a. Fourth, considering the importance of tumor subtypes, GENT2 provides results of various cancer subtype profiling analysis (e.g., stage or grade with various molecular subtypes), Fifth, it provides results of prognostic value estimation using Kaplan-Meier plots. CAS  2018;37(1):18–27.  |  as well as boxplot summaries for user convenience. a Forest plot of hazard ratio on the ERBB2 gene with progression-free survival. Cancer Informat. Coebergh van den Braak RRJ, Sieuwerts AM, Kandimalla R, Lalmahomed ZS, Bril SI, van Galen A, Smid M, Biermann K, van Krieken J, Kloosterman WP, et al. Although the ERBB2 gene showed distinct expression patterns, the log-rank test p-value for each group was found to be insignificant, suggesting that expression difference is irrelevant of prognostic difference. The following sections present the workflows of how the database was constructed. Here, GENT2 is provided as an updated version of GENT with more samples and newer functionalities. In conclusion, with these significant improvements, GENT2 will continue to be a useful tool to a wide range of researchers. For example, progression-free survival in breast tissue for the ERBB2 gene was analyzed by meta-analysis (Fig. 3.6). © 2021 BioMed Central Ltd unless otherwise stated. The full contents of the supplement are available online at https://bmcmedgenomics.biomedcentral.com/articles/supplements/volume-12-supplement-5. To our satisfaction, since its launch at 2011, GENT has been widely used by researchers across the world, with over 1600 visitors per month on average, and the method has been cited more than 100 times in research work [2,3,4,5,6]. -. For example, the GSE9195 dataset is an experiment to identify the effect of tamoxifen in estrogen receptor positive (ER+) breast cancer [10], while the GSE16446 dataset is also an experiment to uncover the effect of anthracycline in estrogen receptor negative (ER-) breast cancer [11]. High mRNA expression of splice variant SYK short correlates with hepatic disease progression in chemonaive lymph node negative colon cancer patients. Sci Rep. 2017;7(1):17841. All interactions in the server layer were implemented by R, RCaller, Apache Lucene software. The SAGE Genie database has been developed to allow in silico analysis of gene expression and comparison of transcript levels in a large number of normal and diseased tissues [ 23 ]. 2011;29(12):1578–86. They show that MYC gene expression … GENT2 is freely available online at http://gent2.appex.kr. The mRNA expression data is derived from deep sequencing of RNA (RNA-seq) from 37 different normal tissue … Shin G, Kang TW, Yang S, Baek SJ, Jeong YS, Kim SY. Subtype and survival analysis. 2015;2015. 2. 2004;20(3):307–15. The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise stated. Especially, applying Lucene index machine, a high-performance information retrieval library, into the GENT2, ultra-fast access across enormous expression data from more than 68,000 samples is available. Each database has its own unique advantages. Nature. PubMed Google Scholar. A. BMC Bioinformatics. Fixed and random effects are shown. PubMed  TE is the estimated treatment effect, seTE is the standard error of the treatment estimate, and HR indicates the hazard ratio average. With these significant improvements, GENT2 is suggested as a versatile tool to assess the biological and prognostic relevance of a specific gene in various cancers. Second, GENT2 provides gene expression information on 72 paired tissues compared to 57 tissues of GENT. Question: Download TCGA cancer and normal tissue gene expression data from GDC . 2020 Oct 28;12(11):3166. doi: 10.3390/cancers12113166. The GENT2 main page consists of three layers for user convenience. Endoplasmic reticulum stress activates SRC, relocating chaperones to the cell surface where GRP78/CD109 blocks TGF-beta signaling. Endoplasmic reticulum stress activates SRC, relocating chaperones to the cell surface where GRP78/CD109 blocks TGF-beta signaling. The top six datasets indicate that the hazard ratios are over 1 for the same gene and the same tissue region (breast), while others show the hazard ratios under 1.
