The mechanism by which Chtop expression is controlled via an autoregulatory negative feedback loop has been established. The results provide a mechanism for maintaining the cellular level of Chtop by intron retention and nonsense-mediated decay of its own mRNA, which will facilitate the development of therapeutic reagents for the treatment of glioblastoma and severe anemia including β-thalassemias and sickle cell disease.
