Further, HOXA1, HOXA10, HOXB7, HOXB9, HOXC6, HOXC9, HOXC10, HOXD10 and HOXD11 showed similar expression patterns in both the primary tumor-derived mouth neoplasms and the cell lines, with some variation noted for HOXB9 in H376 (RRID: CVCL_2463), and HOXC6 with respect to UPCI-SCC-131 (CVCL_2229) cell lines. The gene discussed is HOXC9; the disease is oral cavity neoplasm.
