NDRG2 and cancer: Further analysis revealed six over-lapping genes significantly correlated with ITLN1 in these cancers (Additional file 1: Figure S1B), including NDRG2, chaperonin containing TCP1 subunit 3 (CCT3), defective in cullin neddylation 1 domain containing 5 (DCUN1D5), enolase 1 (ENO1), microtubule-actin crosslinking factor 1 (MACF1), and Mg2+/Mn2+ dependent protein phosphatase 1G (PPM1G).
