Fourteen of these genes (RNF125, FEM1C, FAM54A, ZNF791, AXIN2, B3GNT2, ZNF565, SPON1, TIPARP, ZBTB3, FAM115C, PELO, MXD1, and PFKFB3) were also identified as differentially expressed, and over expressed in BPD in an independent study looking at BPD markers in PBMCs (15). Here, PFKFB3 is linked to bronchopulmonary dysplasia.
