Correlations between risk scores and both pro-tumor factors and stem cell indices were next assessed, revealing that risk scores and the 9 core genes were all strongly positively correlated with MIK67, CTNNB1, KRAS, TP53, and RNAsi, whereas they were not correlated with IDH1 or DNAsi (Figure 11A). This evidence concerns the gene IDH1 and neoplasm.
