LCIIAR and lung cancer: Finally, to confirm LCIIAR expression in lung cancer tissues, we performed qRT-PCR to detect LCIIAR in 19 paired lung cancer and adjacent normal tissues and found significantly higher LCIIAR expression in lung cancer tissues than in adjacent normal tissues (Figure 1H). GEO dataset also confirmed that LCIIAR was up-regulated in lung cancer compared to normal tissues (Figures 1I, J).
