This function allows users to select their custom cancer types for overall or disease-free survival analysis. Primary purpose of the tool is a meta-analysis based discovery and validation of I have experimentally evaluated the expression of some proteins in one type of cancer. the first opinion is they do this assay to confirm their MTT assay results through real pictures, not only numbers or cell viability percentage. But that is for one gene and KMplot is based on gene alteration rather than low vs high expression. TRGAted is an open-source survival analysis application designed to allow for quick and intuitive exploration of TCGA protein-level data. of your sets of the same type. As for now, I am working on some documents and policy briefs. 2G and H, a Kaplan–Meier survival analysis was performed to evaluate the relationship between CDC25C level and prognosis. KM analysis was based on individual gene expression value and survival data. now i confused which one is correct or may be both of the are wrong!!! I want to use the cancer RNA-seq data from TCGA to do some further study but I have no idea to download those NGS data. the second opinion is they do this assay to confirm their results through a longer time period rather than MTT assay. i just finished my pilot study and it was found out that there's one subpart in the adapted questionnaire with a low chronbach's alpha of 0.6. i've done research over the internet that it indicates a 'questionable' remark.
