Stromal transcriptional components in theTME significantly influence the transcriptional classification of BLCA, and the intrinsic biological transcriptional characteristics of cancer cells may be obscured by the dominant, lineage-dependent transcriptional components of stromal origin. This study aimed to explore the degree and mechanisms by which cancer-intrinsic gene expression profiles contribute to the classification and prognosis of BLCA patients.  \nMaterials and methods In this study, BLCA single-cell transcriptome data from GSE135337 were used to identify pure tumor cells in BLCA and explore the different intrinsic heterogeneous cell subgroups of BLCA through pathwaybased cancer transcriptome classification. Additionally, BLCA intrinsic subtypes were uncovered in the TCGA BLCA dataset based on the characteristic genes of the subgroups. Lastly, various machine learning algorithms were applied to identify novel potential targets of BLCA, following which their pro-tumorigenic effects were experimentally verified. Results Four BLCA intrinsic subtypes with different molecular, functional and phenotypic characteristics were successfully identified. Specifically, MA and DP subtypes demonstrated malignant phenotypes, accompanied by unfavorable clinical prognoses, limited involvement in cell death pathways, marked cell proliferation, and diminished immune activation. Notably, MA subtype exhibited the most favorable response to immunotherapy, potentially attributable to its distinctive tumor immune microenvironment. DSM subtype represented an immune-rich subtype with the optimal prognosis, characterized by abundant immune cells, high levels of co-stimulatory, co-inhibitory, major histocompatibility complex molecules, and a potential for immunotherapy response. On the other hand, HM subtype was associated with a high level of autophagy and necrosis and an “immune-hot”TIME.
