The result of bioinformatics analysis by Tao et al. affirmed that miR-141 interacting with circ_0000419 endowed tumor cells with PNI in gastric cancer [89], however, another member of miR-200 family, miR-429 was corroborated to arrest PNI through targeting neurotrophin-3 (NT-3) in pancreatic cancer [14], suggesting the members of miR-200 family had the potential to be novel biomarkers for PNI screening. The gene discussed is NTF3; the disease is gastric cancer.
