GATA5 and squamous cell lung carcinoma: The results implied that GATA1, GATA2, GATA5 and GATA6 were remarkably decreased in lung adenocarcinoma and squamous cell lung carcinoma tissues in comparison with normal lung tissues, whereas there was no significant difference in the expressions of GATA3 and GATA4 between LC and normal lung tissue (Figure 4A-B).
