Despite accumulating evidence supporting its oncogenic role, it has become apparent that NKX2-1/TTF-1 expression also has biological and clinical functions in the opposite direction that act against tumor progression.
TTF1 was involved in cancer progression via the RAS and MYC pathways in CRC, suggesting that TTF1 may be a prognostic indicator and therapeutic target in CRC.
TTF-1 and PTEN can be used as molecular markers for the early diagnosis of endometrial cancer, which are closely related to clinical features and may affect tumor progression by regulating the proliferation activity of tumor cells.
