EEF1A1 and neoplasm: Our analysis of the tumor cell origins (Groups M and T) and cell cycle phases (G1, G2M, and S) revealed that the C3 XIST+ TCs and C1 EEF1A1+ TCs subclusters were predominantly derived from Group T, with very few originating from Group M. Additionally, we assessed the copy number variation (CNV) core and Cell Stemness AUC for each UM subcluster (Figures 1A, E).
