The results of the present study showed that the relative expression levels of FASTKD3, IGF2BP1, MRPL15, SNRPB, and INTS7 were higher in NSCLC tissues than those in control tissues but that the relative expression levels of MBNL2, SMAD9, and ZC3H12C were reduced in NSCLC tissues compared to those in control tissues. This evidence concerns the gene MRPL15 and non-small cell lung carcinoma.
