FASN and neoplasm: The results demonstrated that the overall trend of FASN expression was increased in CESC (p < 0.05), KIRC (p < 0.01), and UCEC (p < 0.001) with increasing tumor malignancy (i.e., lower tumor differentiation), but decreased in HNSC and LGG (p < 0.001), decreasing with tumor progression (Figure 2A).
