. S110, a novel decitabine dinucleotide, increases fetal hemoglobin levels in baboons (P. anubis). J Transl Med. 2010;8:92 pubmed publisher
..S110 is rapidly converted into decitabine, hypomethylates DNA, and induces HbF in cultured human erythroid progenitors and the baboon pre-clinical model. ..

..Thus, decitabine inhibited growth by inducing cell cycle arrest at the G1 phase mediated by p21(WAF1) and the G2/M phase through activation of the p38 MAP kinase pathway. ..

..These studies demonstrate that coordinated epigenetic modifications in the chromatin structure of the beta-like globin gene promoters accompany the highly regulated changes in expression patterns of these genes during development. ..

. Effect of AGM and fetal liver-derived stromal cell lines on globin expression in adult baboon (P. anubis) bone marrow-derived erythroid progenitors. PLoS ONE. 2012;7:e36846 pubmed publisher
..We conclude that Î³-globin expression in adult-derived erythroid cells can be influenced by the micro-environment, suggesting new potential targets for HbF induction. ..

. The LSD1 inhibitor RN-1 recapitulates the fetal pattern of hemoglobin synthesis in baboons (P. anubis). Haematologica. 2016;101:688-97 pubmed publisher
..RN-1 is likely to induce clinically relevant levels of fetal hemoglobin in patients with sickle cell disease, although careful titration of the dose may be required to minimize myelotoxicity. ..
