TGFBR2 and non-small cell lung carcinoma: RT-qPCR and western blot analysis were performed to determine the TGFBR2 mRNA and protein levels in 56 NSCLC tissues and adjacent normal tissues, which showed that the TGFBR2 mRNA and protein levels were lower in the NSCLC tissues than the adjacent normal tissues (p < 0.05, Fig. 6b).
