MALAT1 and non-small cell lung carcinoma: Asshown in Figure 1A, the expression level oflncRNA-MALAT1 was notably higher in NSCLCtissue samples than that in pericarcinomatous normal tissue (P<0.05).To further analyze the relationship betweenlncRNA-MALAT1 expression and clinicalpathological parameters,40 NSCLC patient samples were classified into twogroups in accordance with the median relative quantityof lncRNA-MALAT1.
