Basic Leucine Zipper Transcription Factor, ATF Like Protein 2 (BATF2)

Human BATF2, a basic leucine zipper protein, was recently detected in several normal immortalized cell lines but not in transformed cell lines. In addition, the expression of BATF2 also slowed the growth rate of malignant tumor cells injected into athymic nude mice.Moreover, BATF2 expression in 114 HCC patients was evaluated using immunohistochemistry, and its relationship with clinicopathological parameters and prognosis was investigated. BATF2 expression was significantly reduced in most HCC tumorous tissues, when compared with nontumorous tissues, as well as in the five HCC cell lines.
