PTGDR and hepatocellular carcinoma: The growing evidence shows that PVT1 promotes proliferation, invasion, metastasis, and drug resistance in many cancer cells,57 and can act as a prognostic indicator.58 MAGI2‐AS3 is another confirmed lncRNA that can suppress hepatocellular carcinoma cell proliferation and migration by acting as an endogenous sponge of miR‐374b‐5p.59 NR2F1‐AS1 can regulate hepatocellular carcinoma oxaliplatin resistance through targeting miR‐363‐ABCC1 pathway.60 In our analysis, MAGI2‐AS3 and NR2F1‐AS1 showed highly positive correlation with COL1A1 via miR‐143‐3p.
