POLRMT and non-small cell lung carcinoma: In primary human NSCLC cells derived from three different patients (pNSCLC1, pNSCLC2, and pNSCLC3) and the established A549 cells, POLRMT mRNA (Fig. 1G) and protein (Fig. 1H) expressions were significantly higher than those in the primary lung epithelial cells (“Lung epi”) (Fig. 1G, H).
