MCRS1 DNA copy numbers and MCRS1 mRNA expression levels. a Changes in the MCRS1 gene copy number and the level of MCRS1 mRNA expression in cultured cells were evaluated using qRT-PCR. b The variation in the MCRS1 DNA copy number in the NSCLC tissues was compared with that of noncancerous lung tissues. (Student’s t-test, *P < 0.05). c The results of the correlation analysis of the MCRS1 mRNA expression levels and the MCRS1 copy number alterations. (Pearson’s method, R = 0.4, *P < 0.05)
