Respectively, the expression of CDO1 (Fig. 5A), CELF2 (Fig. 5B), ITPRIPL1 (Fig. 5C), KCNH8 (Fig. 5D), RIC3 (Fig. 5G), USP44 (Fig. 5H) and ZSCAN23 (Fig. 5J) was significantly lower in tumor tissues, whereas the expression of PTK6 (Fig. 5E) and RAB25 (Fig. 5F) was significantly higher in tumor tissues. The gene discussed is CDO1; the disease is neoplasm.
