HOXB7 and cancer: In the tail vein injection models, increased expression of HOXB7 resulted in significantly greater numbers of macroscopic lung metastatic cancer nodules in the mouse lung tissues, with the MGC-803-B7 (100 ± 21.36) and BGC-823-shNC (112.5 ± 17.25) groups showing increased foci relative to MGC-803-NC (15.83 ± 4.84) and BGC-823-shB7 group (17.5 ± 5.88) (t-test, P<0.05).
