To evaluate the potential role of kinesin in lung adenocarcinoma, we first examined the frequency of LOH in chromosomes using microsatellite markers, and observed that LOH occurred between markers D1S1660 (40.0% LOH and 86.7% microsatellite instability (MI)) and D1S213 (31.6% LOH and 60.5% MI), which are located near KIF14 on chromosome 1q (Figure 1A). The gene discussed is KIF14; the disease is lung adenocarcinoma.
