PMEPA1 Is a Prognostic Biomarker That Correlates With Cell Malignancy and the Tumor Microenvironment in Bladder Cancer

Prostate transmembrane protein androgen induced 1 ( ) has been reported to promote cancer progression, but the potential role of in bladder cancer (BLCA) remains elusive. We assess the role of in BLCA, a publicly available database and study. was identified from 107 differentially expressed genes (DEGs) to have prognostic value. GO, KEGG, and GSEA analysis indicated that was involved in cancer progression and the tumor microenvironment (TME). Then bioinformatical analysis in TCGA, GEO, TIMER, and TISIDB show a positive correlation with the inflammation and infiltration levels of three tumor-infiltrating immune cells (TAMs, CAFs, and MDSCs) and immune/stromal scores in TME. Moreover, study revealed that promotes bladder cancer cell malignancy. Immunohistochemistry and survival analysis shed light on potential to be a novel biomarker in predicting tumor progression and prognosis. At last, we also analyzed the role of in predicting the molecular subtype and the response to several treatment options in BLCA. We found that may be a novel potential biomarker to predict the progression, prognosis, and molecular subtype of BLCA.
