FOXM1 and neoplasm: Fig 4A and 4B illustrated the positive correlation between TFRC and FOXM1 expressions and tumor stages, as well as their association with tumor stages in LUAD samples using spearman correlation (P < 0. 05). Similarly, LUSC samples showed a positive correlation between MIG6 and tumor stage, as depicted in Fig 4C and 4D using spearman correlation.
