TGFB1 and non-small cell lung carcinoma: In the future, identifying the molecular profile of TGFβ1 sensitive NSCLC lines and exploring the effects of TGFβ1 on lymphangiogenesis in vivo will lead to a better understanding of the role of TGFβ1 in lung cancer progress and eventually to TGFβ pathway inhibitors that could be used for clinical treatment.
