In contrast, GFPT1 expression was lower in GBM (glioblastoma multiforme, p = 0.020), KIRC (kidney renal clear cell carcinoma, p = 3.79E-06), KIRP (kidney renal papillary cell carcinoma, p = 0.016), and THCA (thyroid carcinoma, p = 7.99E-05) tumor tissues compared to normal tissues (Figure 1A). Here, GFPT1 is linked to thyroid gland carcinoma.
