SLC25A5 and neoplasm: Previous studies have demonstrated that miR‐19a plays critical roles in multiple malignant tumours and participates in a variety of biological processes, including cell proliferation, cell cycle and apoptosis, etc.12, 13 To further confirm that the mutual regulation between SLC25A5‐AS1 and miR‐19a‐3p on these biological processes, miR‐19a‐3p mimics were co‐transfected with SLC25A5‐AS1 in GC cells to perform rescue experiments.
