The mRNA and protein expression of NDRG2 showed to be dramatically downregulated within ovarian cancer tissues than that in non-cancerous tissue samples (Fig. 1a&b); similarly, the expressions of NDRG2 protein were lower in ovarian cancer tissues than non-cancerous tissue samples by IHC assay (Fig. 1c). The gene discussed is NDRG2; the disease is ovarian cancer.
