DDX5 and neoplasm: Of the 23 types of tumors, the expression of DDX5 was negatively correlated to the promoter methylation levels in five tumor types, including BRCA (p = 5.47E-06, r = −0.153693), ESCA (p = 2.70E-03, r = −0.228029), SARC (p = 8.53E-03, r = −0.161896), STAD (p = 8.72E-03, r = −0.142683), and HNSC (p = 4.27E-03, r = −0.088734); however, the expression of DDX5 and the promoter methylation levels were positively correlated in THCA (p = 2.70E-03, r = 0.118651).
