Abstract:
Fra-1 is thought to play an important role in tumorigenesis and progression. This study aimed to investigate the expression and significance of Fra-1 in non-small-cell lung cancer (NSCLC). By analyzing with Western blot and immunohistochemistry, we found that Fra-1 is downregulated in NSCLC, compared with normal bronchial epithelium. Further, the low expression of Fra-1 correlates with advanced tumor stage and poor survival. Meanwhile, the distinct cytoplasmic location of Fra-1 was found in almost all immunoreactive cells. These findings reveal a potential nontranscriptional function of Fra-1, and indicate that Fra-1 might play a role in the progression and prognosis of NSCLC.
