The obtained data showed statistically significant differences of relative quantification (RQ) MTNR1A mRNA (p = 0.022) (Figure 4C) and MTNR1B mRNA (p < 0.0001) (Figure 4D) expression levels according to the histology type of NSCLC. The gene discussed is MTNR1B; the disease is non-small cell lung carcinoma.
