SOX4 and gastric carcinoma: Moreover, we co-transfected si-MIR4435-2HG with anti-miR-138-5p and pcDNA-Sox4 and found that the proliferation, invasion, migration, apoptosis, and EMT of gastric carcinoma transfected with anti-miR-138-5p and pcDNA-Sox4 were reversed after co-transfection with si-MIR4435-2HG.
