In order to investigate the effect of miR‑27b on GC cell behavior, miR‑27b was overexpressed using miR‑27b mimics, and it was observed that miR‑27b was able to inhibit cell proliferation and induce apoptosis in SGC7901 cells.
Thus, we identified three miRNAs (hsa-miR-421, hsa-miR-29b-1-5p, and hsa-miR-27b-5p) with two mRNAs (FBXO11 and CREBZF) that might play an important role in the GC development from premalignant adenomas.
We conclude that CREB1 is a promising biomarker to predict tumor metastasis and patient outcome in gastric cancer, and the miR-27b/miR-200b-CREB1 pathway may serve as a potential molecular target for the treatment of gastric cancer.
