The results showed that ADRA1A, ANGPTL1, FBXO32, KCNMA1, and DCN were downregulated in endometrial carcinoma tissues; LEFTY1, LIN28A, LHX3, ST8SIA3, and CEP55 were upregulated in endometrial carcinoma tissues; and the upregulation trend of LIN28A, LHX3, and ST8SIA3 was relatively small (Figure 7). The gene discussed is KCNMA1; the disease is endometrial carcinoma.
