In Hou's dataset 31 and Garber's dataset 32, the transcription levels of GATA2 in squamous cell lung carcinoma, lung adenocarcinoma and large cell lung carcinoma were both lower than those in lung tissues, and their FC are -3.780/-2.475/-4.077 and -3.551/-2.318/-2.194, respectively. Here, GATA2 is linked to lung adenocarcinoma.
