These q-value filtered datasets were loaded onto the IPA program in order to further characterize the molecular processes they may reflect. Consistent with previous observations, a preliminary characterization suggested an increase in organismal death and inflammation-related processes in the endometrial fluid of non-implantative women, as well as an inhibition of cell movement and migration-related terms (Table II, Supplementary File S5). Interestingly, both datasets reflected a link between the deregulated proteins and the PI3K/AKT signaling pathway, as well as with the transcription regulator nuclear factor, erythroid 2 like 2 (Nfe2l2, also named Nrf2) (Fig. 3). Based on the differential protein expression pattern, both signaling networks appear to be inhibited in the non-implantative EFA.
