Interestingly, specific miRNA-mRNA pairs were discovered for both subtypes: six for serous adenocarcinoma (hsa-miR-23a-5p~EMP1, hsa-miR-126-3p~CH25H, hsa-miR-126-3p~HBB, hsa-miR-126-3p~NAMPT, hsa-miR-126-3p~POSTN, and hsa-miR-486-5p~HBEGF) and two for non-serous adenocarcinoma (hsa-miR-223-3p~POSTN and hsa-miR-223-3p~PROCR). Here, HBB is linked to serous adenocarcinoma.
