Identification of Metabolic Reprogramming Related Gene Signature to Predict the Prognosis of Bladder Cancer Patients
Abstract Background: Different kinds of metabolic reprogramming have been widely researched in multifarious cancer types and show up as a guaranteed prognostic predictor, while bladder cancer (BLCA) is most frequent urothelium carcinoma but with poor prognosis despite there are emerging treatments, for lack of reliable predicting biomarkers to early predict the prognosis and delayed treatment options for patients in the terminal stage. Our study aims to explore new prognostic factors related to metabolism in BLCA and make these genes up as novel risk stratification.Methods: We selected a large number of samples downloaded from TCGA (The Cancer Genome Atlas) to find out the possible glycolysis-related genes that correlated with differentiation from cancer sample to normal tissue, aimed to find out a more credible model. To make our signature more believable, we chose the clinical features information from GEO (Gene Expression Omnibus) database as external validation cohort.Results: Finally, we established a three glycolysis-related gene signature based on the expression of AK3, GALK1 and NUP205 to make a prediction on the prognosis of BLCA patients, which were also validated by external cohort and whole mixed cohort. As a result, we built a three glycolysis-related gene signature and found its prognosis value is more valuable in high malignancy patients, which may help physicians to make a more aggressive choice.
