Auto-regulatory mechanism for the expression of Chtop, a key protein factor for
carcinogenesis of glioblastoma and developmental transition from fetal to adult hemoglobin.

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.
