Research on TTF-1 extends beyond its diagnostic use in pathology. In developmental biology, TTF-1 is studied to understand its role in organogenesis and cellular differentiation. Additionally, in cancer research, TTF-1 is investigated for its potential role in tumorigenesis and as a therapeutic target. Understanding the molecular mechanisms by which TTF-1 regulates gene expression can provide insights into new treatment strategies for cancers expressing this transcription factor.
