TGFBI and lung carcinoma: Interestingly, dense methylation (≥ 16 methylated CpG sites) of the TGFBI promoter was identified in 16.0% (8/50) of lung cancer and 28.0% (14/50) of prostate cancer specimens, respectively, which in turn correlated significantly with metastatic phenotype in lung cancers and locoregional invasiveness in prostate cancers.
