EMSLR and lung adenocarcinoma: Having identified LncPRESS1 as a target of EMSLR, we assayed the expression pattern of EMSLR and LncPRESS1 in cell lines displaying varying degrees of tumor-related phenotypes: (1) MRC-5, a human lung fibroblast cell line derived from normal lung tissue which is used as a control for non small cell lung cancer; (2) BEAS-2B, a non-tumorigenic lung epithelial cell line and (3) A549, an aggressive lung adenocarcinoma cell line40.
