Expression level of melatonin receptor MT1 in regard to patients clinico-pathological factors. (A) Comparison of immunohistochemical MT1 expression in non-malignant lung tissue (NMLT) with its expression in non-small cell lung carcinoma (*** p < 0.001); Mann Whitney test. Expression levels of MT1 in respect to (B) tumor size (** p < 0.01) and (C) clinical cancer stage (* p < 0.05); Dunn’s Multiple Comparison test.
