PTGDR and gastric cancer: For instance, the eukaryotic translation initiation factor 3 subunit J-divergent transcript (EIF3J-DT) can trigger chemoresistance in gastric cancer by activating autophagy [8], and the poly (RC)- binding protein 1-antisense RNA 1 (PCBP1-AS1) inhibits lung adenocarcinoma metastasis by suppressing EMT progression [9].
