Abstract

FOXF1 expression was overexpressed in infantile hemangioma tissues.

  • Silencing FOXF1 inhibited proliferation, migration, and invasion of infantile hemangioma cells while promoting apoptosis.
  • ALKBH5 upregulation was associated with increased stability and expression of FOXF1 mRNA in infantile hemangioma cells.
  • FOXF1 downregulation reversed the effects of ALKBH5 on cellular behaviors in infantile hemangioma.
  • FOXF1 positively influenced hexokinase 2 (HK-2) expression by interacting with its promoter in infantile hemangioma cells.
  • Suppression of ALKBH5 or FOXF1 reduced tumor growth in infantile hemangioma in immunocompromised mice through HK-2 signaling.
