As shown in Figure 1D, Cox regression analysis showed that the expression of FDX1 was positively correlated with the prognosis of adrenocortical carcinoma (ACC) and lower grade glioma (LGG); and negatively correlated with the prognosis of colon adenocarcinoma (COAD), liver hepatocellular carcinoma (LIHC) and thyroid carcinoma (THCA). The gene discussed is FDX1; the disease is thyroid gland carcinoma.
