[Angiopoietin-like 4 modulates aldolase A expression in human melanoma cell in a PKC dependent manner].

Objective: To investigate the association between angiopoietin-like 4 (ANGPTL4) and aldolase A (ALDOA) in human melanoma cell. 


Methods: Overexpression or knockdown of ANGPTL4 was performed in WM-115 or WM-266-4 cells, respectively. The expression of ANGPTL4 and ALDOA was measured by RT-PCR and Western blot, respectively. The promoter activity of ALDOA gene was determined by luciferase assay.


Results: The promoter activity of ALDOA gene and the expression of ALDOA (mRNA and protein) were increased or decreased in the melanoma cells with overexpression or knockdown of ANGPTL4, which was blocked by selective protein kinase C (PKC) inhibitor or restored by PKC agonist, respectively.


Conclusion: ANGPTL4 promotes ALDOA expression in human melanoma cell in a PKC dependent manner.
