For example, circ-MYBL2, a circRNA from MYBL2 gene, is reported to facilitate the progression of acute myeloid leukemia by regulating fms-related receptor tyrosine kinase 3 (FLT3) translation through recruiting polypyrimidine tract binding protein 1 (PTBP1) [9]. The gene discussed is FLT3; the disease is acute myeloid leukemia.
