Pan-cancer patterns of cuproptosis markers reveal biologically and clinically relevant cancer subtypes.

ABSTRACT: Cuproptosis is a newly discovered type of cell death triggered by copper accumulation. Here we exhibited the genetic profiles of 10 cuproptosis-associated genes (CuAGs) across 21 cancer types. Only 8.0% (627/7839) of tumors possessed at least 1 mutation on CuAGs, while the copy number amplifications or deletions on the alleles of CuAGs were ubiquitous. Generally, the expression of CuAGs showed heterogeneity across cancer types and the expression of CuAGs showed different correlations with MSI, TMB, immune and stromal features in different cancer types. Therefore, CuAGs were ubiquitously and heterogeneously dysregulated in pan-cancer. With a Non-negative Matrix Factorization method, we divided patients of each cancer type into cuproptosis-based subtypes, which showed a close but heterogeneo
