HMGB3 and gastric cancer: The functions of Meis2 and HMGB3 are carried out through multi-step bioinformatics methods, and needed to be further confirmed in our future research through in vitro and in vivo experiments; however, these data provide clues for studying the mechanism of the miR18/Meis2 axis regulating HMGB3 to promote the stemness of GC cells.
