HOXA9 inhibits migration of lung cancer cells and its hypermethylation is associated with recurrence in non-small cell lung cancer

This study was aimed at understanding the clinicopathological significance of HOXA9 hypermethylation in non‐small cell lung cancer (NSCLC). HOXA9 hypermethylation was characterized in six lung cancer cell lines, and its clinicopathological significance was analyzed using methylation‐specific PCR in 271 formalin‐fixed paraffin‐embedded tissues and 27 fresh‐frozen tumor and matched normal tissues from 298 NSCLC patients, and Ki‐67 expression was...
