RESUMEN
Lipoprotein lipase (LPL) plays a key role in the lipid metabolism and transporting. It can catalyze the hydrolysis of chylomicron and very low-density lipoprotein triglyceride. Moreover, the abnormality of LPL associates with many pathophysiological conditions. Herein cDNA microarray and Northern blots analysis were used to study the expression of lipoprotein lipase in lung adenocarcinoma tissues. There were 113 genes of all tested blots in cDNA microarray expressed lowly. LPL gene is expressed lowly at the average ratio 0.26 (Cy5/Cy3) in lung adenocarcinoma tissues over controls. Northern blots confirmed those changes detected from the cDNA microarray and suggested that low expression of LPL may play an important role in the lung adenocarcinoma development.
