Meanwhile, a novel protein consisting of 570 amino acids (OGT-570aa) encoded by exonic circular OGT RNA (ecircOGT) is able to competitively bind with FOXC1, leading to a decrease in OGT–FOXC1 interaction, ASNS and GPT2 expression, asparagine and alanine biogenesis, and ferroptosis resistance of NB cells. This evidence concerns the gene OGT and neuroblastoma.
