For instance, the lncRNA-mRNA network constructed in gastric adenocarcinoma has shown the possible role of the AC115619.1-APOA4/APOB and AP006216.2-APOA1/APOA4 axes in the pathogenesis of this cancer through regulation of fat digestion and absorption as well as vitamin digestion and absorption [108]. This evidence concerns the gene APOA4 and gastric adenocarcinoma.
