Figure 4. Promotion of tumor growth in mice by overexpression of HOXC10 in A549 cells. (A) A549 cells that stably overexpress HOXC10 (A549_HOXC10) or control (A549_GFP) were grafted into the flank of nude mice as described in the section of Materials and Methods. Volumes of the tumors formed by A549_HOXC10 and A549_GFP monitored from week 2 to week 4. Growth curves were illustrated. (B) The tumors were dissected and recorded on week 4 post inoculation. * indicates a P value < 0.05.
