Dysregulated mitochondrial energy metabolism drives the progression of mucosal field effects to invasive bladder cancer.

ABSTRACT: Multiplatform mutational and gene expression profiling complemented with proteomic and metabolomic spatial mapping were used on the whole-organ scale to identify the molecular profile of bladder cancer evolution from field effects. Analysis of the mutational landscape identified three types of mutations, referred to as α, β, and γ. Time modeling of the mutations revealed that carcinogenesis may span 30 years and can be divided into dormant and progressive phases. The α mutations developed in the dormant phase. The progressive phase lasted 5 years and was signified by expanding β mutations, but it was driven to invasive cancer by γ mutations. The mutational landscape emerged on a background of disorganized urothelial differentiation, activated epithelial-mesenchymal transition, and enhanced
