Cells in which the expression of FoxQ1 was silenced (SPC-A-1-FoxQ1 and NCI-H1395-FoxQ1), their corresponding control cells (SPC-A-1-scr and NCI-H1395-scr) and normal control cells were subcutaneously injected into the bilateral flank, and tumor size was measured and recorded every three days. The gene discussed is FOXQ1; the disease is neoplasm.
