Circular RNA circPGD Contributes to Gastric Cancer Progression via the Sponging miR-16-5p/ABL2 Axis and Encodes a Novel Pgd-219aa Protein

Functionally, circPGD promoted cell proliferation, migration, and suppressed apoptosis in vitro. Mechanistically, circPGD sponged miR-16-5p for relieving miR-16-5p suppression on the corresponding target ABL2 via the SMAD2/3 and YAP signaling pathways.
