Furthermore, comparisons using published TTF‐1 ChIP‐seq data of other NSCLC cell lines (SRP045118) (Clarke et al., 2015) revealed that while TTF‐1 binding regions in NCI‐H1819 and HCC1195 cells showed more overlap with H441 cells, TTF‐1 binding regions in HCC1833 cells, which were derived from LADC with neuroendocrine features (Kosari et al., 2014), showed comparable ratios of overlap in H209 and H441 cells (Fig. 2E). The gene discussed is TTF1; the disease is non-small cell lung carcinoma.
