Consistently, the protein levels of MRTF-A and PD-L1 were significantly higher in NSCLC tissue samples than in control normal tissue samples (Fig. 3c, d), and there was a positive correlation between MRTF-A and PD-L1 in NSCLC patients (Fig. 3e). The gene discussed is MRTFA; the disease is non-small cell lung carcinoma.
