After HG treatment, FOXO1 expression was upregulated, while the expression levels of IGF1R, phosphorylated FOXO1 Ser249, MMP2, MMP9, and VEGFA were downregulated.<h4>Conclusion</h4>In summary, our study is the first to demonstrate that HG regulates the phosphorylation of FOXO1, affecting the proliferation, migration, and invasion of HCC cells. Here, IGF1R is linked to hepatocellular carcinoma.
