As shown in Fig. 1b, the CKMT1A expression level was significantly higher in tumor tissues than in the corresponding controls in OV (Ovarian serous cystadenocarcinoma), TGCT (Testicular germ cell tumors) and UCS (Uterine carcinosarcoma) (all P < 0.05). The gene discussed is CKMT1A; the disease is uterine carcinosarcoma.
