FOXR2 (forkhead box R2) is a transcription factor belonging to the FOX gene family that functions as a proto-oncogene with significant roles in cancer pathogenesis 1. As a DNA-binding transcription factor with RNA polymerase II-specific activity, FOXR2 localizes to the nucleus and nucleoplasm where it regulates gene expression 2. The protein promotes cell proliferation and malignancy through activation of downstream effectors including β-catenin, Skp2, c-Myc, and Gli-1 3. FOXR2 also enhances the Sonic Hedgehog pathway by upregulating Shh, Gli1, and Ptch1 expression 4. Clinically, FOXR2 overexpression is associated with multiple cancer types including hepatocellular carcinoma, colorectal cancer, and notably defines a distinct subgroup of aggressive pediatric brain tumors called CNS neuroblastoma with FOXR2 activation (CNS NB-FOXR2) 534. In pineoblastomas, FOXR2 overexpression characterizes the PB-MYC/FOXR2 molecular subgroup, which has a dismal prognosis 6. The oncogene promotes not only proliferation but also invasion, metastasis, and epithelial-mesenchymal transition in cancer cells 4. Given its consistent overexpression across various malignancies and poor prognostic associations, FOXR2 represents a promising therapeutic target for cancer treatment 7.
