KNL1 and gastric cancer: In addition, our results revealed that the downregulation of miR-193b-3p might contribute to GC cell proliferation by mediating the upregulation of NCAPG. Additionally, the downregulation of miR-193b-3p might contribute to the mitotic nuclear division of GC cells by mediating the upregulation of KNL1. These results provide a theoretical direction for future research with regards to the molecular mechanisms of the progression of GC.
