HCP5 and gastric cancer: Another study showed that the co-culture of gastric cancer cells with MSCs induced the long non-coding RNA (lncRNA) HCP5 (histocompatibility leukocyte antigen complex P5), which drove fatty acid oxidation through the miR-3619-5p-AMPK-PGC1α/CEBPB axis and resulted in the promotion of stemness and the induction of chemoresistance [140].
