Conclusion
FOXA3 promotes the occurrence and development of HB by up-regulating AFP and HNF1A/MYC expression, and down-regulating ZFHX3 expression.
Methods
Immunohistochemistry was applied to determine the expression situation of FOXA3 and AFP in HB tissues and the adjacent normal tissues. FOXA3, HNF1A, and ZFHX3 expressions in HB tissues and the normal tissues were measured by Western blot. HB cell lines were randomly divided into 4 groups: Model, si-NC, si-FOXA3-1, and si-FOXA3-2 group. The HB cell viability and colony formation characteristics in the 4 groups were explored by CCK-8 and cell cloning formation assay, respectively. The expression of FOXA3, AFP, HNF1A, ZFHX3, and MYC in HB cells after knockdown of FOXA3 was measured.
Objective
In this research paper, we aimed to study the role of FOXA3 in hepatoblastoma (HB) and the molecular mechanism.
Results
FOXA3, AFP, and HNF1A expressions were significantly up-regulated in HB tissues, while ZFHX3 expression was down-regulated. Knockdown of FOXA3 markedly inhibited HB cell viability and cloning formation ability. Knockdown of FOXA3 decreased FOXA3, AFP, and HNF1A/MYC expression, while increased ZFHX3 expression.
