To comprehensively understand these four lncRNAs (LINC01224, CASC9, LINC00346, and TRPM2-AS) and seven target mRNAs (CCNF, PKMYT1, GCH1, TK1, PSAT1, ADAM33, and DDX11), we performed genome instability, immune, cancer stemness, and drug sensitivity analysis. This evidence concerns the gene TK1 and cancer.
