Mining of prognosis-related genes in cervical squamous cell carcinoma immune microenvironment

Abstract

Purpose The aim of this study was to explore the effective immune scoring method and mine the novel and potential immune microenvironment-related diagnostic and prognostic markers for cervical squamous cell carcinoma (CSSC). Materials and Methods The Cancer Genome Atlas (TCGA) data was downloaded and multiple data analysis approaches were initially used to search for the immune-related scoring system on the basis of Estimation of STromal and Immune cells in MAlignant Tumour tissues using Expression data (ESTIMATE) algorithm. Afterwards, the representative genes in the gene modules correlated with immune-related scores based on ESTIMATE algorithm were further screened using Weighted Gene Co-expression Network Analysis (WGCNA) and network topology analysis. Gene functions were mined through enrichment analysis, followed by exploration of the correlation between these genes and immune checkpoint genes. Finally, survival analysis was applied to search for genes with significant association with overall survival and external database was employed for further validation. Results The immune-related scores based on ESTIMATE algorithm was closely associated with other categories of scores, the HPV infection status, prognosis and the mutation levels of multiple CSCC-related genes (HLA and TP53). Eighteen new representative immune microenvironment-related genes were finally screened closely associated with patient prognosis and were further validated by the independent dataset GSE44001. Conclusion Our present study suggested that the immune-related scores based on ESTIMATE algorithm can help to screen out novel immune-related diagnostic indicators, therapeutic targets and prognostic predictors in CSCC.

Multi-Omics Data Analyses Construct a Six Immune-Related Genes Prognostic Model for Cervical Cancer in Tumor Microenvironment

“…However, the current understanding remains unsatisfactory and insufficient. Numerous previous research studies concentrated mainly on the RNA-seq profiles, which are characterized by some disadvantages in comprehensively clarifying the potential mechanisms involved ( Sun et al, 2019 ; Liu et al, 2020 ; Ma J. et al, 2020 ; Zhao et al, 2020 ; Yang et al, 2021 ). Many researchers have recently concentrated on investigating prognostic factors by integrative multi-omics data analysis, which yielded more powerful results and provided a more comprehensive view of the TME ( Gu et al, 2020 ; Ma H. et al, 2020 ; Yan et al, 2020 ; Zhang Y. et al, 2020 ; Xu et al, 2021 ).…”

Eight Aging-Related Genes Prognostic Signature for Cervical Cancer

“…Anti-tumor research has recently focused on identifying the key characteristics of tumor cell senescence [ 16 ]. Numerous signatures have been developed to predict the overall survival (OS) of CC patients, such as immune-related genes pairs signature [ 17 ], autophagy-related gene prognostic risk model [ 18 ], lncRNA immune prognostic signature [ 19 ], and prognosis-related genes in carcinoma immune microenvironment [ 20 ]. However, aging-related genes (ARGs) utilized to predict CC prognosis are poorly described.…”
