Objective

Pancreatic cancer is a devastating and lethal malignancy. Our study investigated the effective mechanism of HNF4G on pancreatic cancer cell functions through the IGF2BP2 transcription.

Methods

HNF4G and IGF2BP2 expressions in pancreatic cancer were examined. The relationship between HNF4G expression and pancreatic cancer patients' clinicopathological characteristics was evaluated. After interfering with HNF4G expression in pancreatic cancer cells, the cell proliferative, migratory, and invasive capabilities were evaluated. Also, the expression of proliferation-related gene PCNA and migration and invasion-related gene MMP2 was determined. The binding relation between HNF4G and HNF4G promoter was forecasted and testified. A tumorigenesis assay in nude mice was performed to detect the HNF4G interference's effect on the subcutaneous tumorigenic capacity of pancreatic cancer cells.

Results

HNF4G and IGF2BP2 expressions were up-regulated in pancreatic cancer. Specifically, interfering with HNF4G inhibited PANC-1 cell proliferative, invasive and migratory behaviors, and decreased PCNA and MMP2 expression. Mechanistically, HNF4G as a transcription factor could specifically bind to IGF2BP2 and promote its expression. Rescue assay findings showed that IGF2BP2 overexpression could reverse the inhibiting effect of HNF4G interference on pancreatic cancer cells. For the in vivo finding, interfering HNF4G expression retarded the subcutaneous tumorigenic ability of pancreatic cancer cells.

Conclusion

We summarize that HNF4G as a transcription factor regulates IGF2BP2 expression to promote pancreatic cancer cell proliferation and migration capacities."xsd:string
