This is substantiated by the observation that, similarly to some types of SGR that affect the RNA decay machinery (for example, DIS3 or MTREX; Fig. 4c) and likely increase the level of functional hTR, an inhibitor of the hTR poly(A) polymerase PAPD5 increases the level of mature hTR and improves the potential of haematopoietic stem and progenitor cells in the context of PARN or dyskerin deficiency59,237,238,239.
