Overexpression of HOXB7 facilitated tumor growth in vivo. a SMMC-7721/scramble, SMMC-7721/shHOXB7, HepG2/vector and HepG2/HOXB7 cells were subcutaneously injected in the hind limbs of nude mice (n = 6/group; 1 × 105 cells). b, c Tumor weight and volume were measured in each group (P < 0.05, respectively). d, e Representative histopathology of xenograft tumors. The tumor sections were subjected to IHC staining using antibodies against HOXB7 and Ki-67
