Knockdown of miR-142-5p and overexpression of SOX4 can reverse this performance, indicating that NNT-AS1 may activate the Wnt/β–catenin signaling pathway through the miR-142-5p/SOX4 axis, and then induce the proliferation, migration, invasion, and apoptosis inhibition of GC cells [35]. Here, NNT is linked to gastric cancer.
