Protein expression of SPAG6 and L1TD1 in NSCLC patients. Representative IHC stainings of NL and TU samples are shown. In unmethylated NL samples cytoplasmic expression of SPAG6 a and L1TD1 b was observed in bronchial and bronchiolar epithelial cells. In SPAG6 a, respectively, L1TD1 b methylated TU samples neither SPAG6 nor L1TD1 expression was observed in tumor cells. c The comparison between SPAG6 and L1TD1 protein expression and SPAG6 or L1TD1 methylation by T/N methylation ratios and IHC groupings of 35 TU samples is shown
