A Novel Risk Score Model of Lactate Metabolism for Predicting over Survival and Immune Signature in Lung Adenocarcinoma

Abstract: Background: The role of lactate acid in tumor progression was well proved. Recently, it was found that lactate acid accumulation induced an immunosuppressive microenvironment. However, these results were based on a single gene and it was unclear that lactate acid genes were associated with immunotherapy and able to predict overall survival. Methods: Genes and survival data were acquired from TCGA, GEO and GENECARDS. PCA and TSNE were used to distinguish sample types according to lactate metabolism-associated g… Show more

“…Using 16 metabolic genes, a previous study constructed a prognostic model for LUAD and it reached an AUC value of 0.638 on 3-year prognosis prediction in the independent dataset (GSE37745) (He et al, 2020). Another study provided a risk score model for LUAD by six genes, and it reached an AUC value of 0.66 on 3-year prognosis prediction in GSE37745 (Jiang et al, 2022). In a LUAD prognosis model constructed by 27 hypoxia-related genes, it showed AUC values of 0.65 and 0.66 in the validation datasets (Ouyang et al, 2021).…”

“…The maximum number of clusters k = 9 and the optimal number of clusters were synthesised based on the cumulative distribution function (CDF) curve, consensus matrix, and consistent cluster score. PCA was then used in conjunction with t-distributed stochastic neighbour embedding (tSNE) to determine whether these genes could be used to distinguish samples ( 28 , 29 ).…”

“…Disease prediction models have been widely used to evaluate patient survival and other prognostic indicators in LUAD ( Jiang et al, 2020 ; Jiang et al, 2022 ). Recently, a novel model related to lactate metabolism for predicting overall survival and immune signature in LUAD was reported and different immune signatures were built ( Jiang et al, 2022 ).…”

Recently, a novel model related to lactate metabolism for predicting overall survival and immune signature in LUAD was reported and different immune signatures were built ( Jiang et al, 2022 ). Moreover, an increasing number of LUAD prognostic biomarkers have been discovered by analyzing expression profiles from public databases and related clinical information ( Jiang et al, 2020 ).…”
