In light of that when HOXA9 is abundantly expressed in NSCLC cells, tumor aggressiveness is reduced [101], Seong-Lan Yu et al. split the protein-coding sequences of HOXA9 into three regions with overlapping parts, to determine the sequence motif of HOXA9 linked to its inhibitory action on cell motility in NSCLC cells. This evidence concerns the gene HOXA9 and non-small cell lung carcinoma.
