St. Jude Reference #SJ-20-0030
There are currently poor drug choices to treat beta thalassemia, a chronic, often debilitating form of genetic anemia that is very common in some parts of the world. New treatments might be achieved using “antagomirs” (oligonucleotides that interfere with the functions of natural microRNAs).
Researchers at St. Jude discovered that genetic disruption of the red cell expressed microRNA locus miR144/451 causes a dramatic reduction in the severity of beta thalassemia. They believe that miR451 acts through a biochemical signaling cascade to inhibit the activity of the autophagy protein ULK1, which we recently showed to reduce the severity of beta thalassemia by degrading toxic free alpha globin (Lechauve et al, Science Translational Medicine, 2019).
