    Lavelle D, Chin J, Vaitkus K, Redkar S, Phiasivongsa P, Tang C, et al. Oral decitabine reactivates expression of the methylated gamma-globin gene in Papio anubis. Am J Hematol. 2007;82:981-5 pubmed
  2. Rivers A, Vaitkus K, Jagadeeswaran R, Ruiz M, Ibanez V, Ciceri F, et al. Oral Administration of the LSD1 Inhibitor ORY-3001 Increases Fetal Hemoglobin in Sickle Cell Mice and Baboons. Exp Hematol. 2018;: pubmed publisher
    ..33 ?/?+?). We conclude that oral administration of ORY-3001 increased F retics, ?-globin chain synthesis, and ?-globin mRNA in SCD mice and in baboons, supporting further efforts toward the development of this drug for SCD therapy. ..
  3. Lavelle D, Saunthararajah Y, Vaitkus K, Singh M, Banzon V, Phiasivongsva P, et al. 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. ..

    Lavelle D, DeSimone J, Hankewych M, Kousnetzova T, Chen Y. Decitabine induces cell cycle arrest at the G1 phase via p21(WAF1) and the G2/M phase via the p38 MAP kinase pathway. Leuk Res. 2003;27:999-1007 pubmed
    ..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. ..

    Lavelle D, Vaitkus K, Hankewych M, Singh M, DeSimone J. Developmental changes in DNA methylation and covalent histone modifications of chromatin associated with the epsilon-, gamma-, and beta-globin gene promoters in Papio anubis. Blood Cells Mol Dis. 2006;36:269-78 pubmed
    ..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. ..

    ..We conclude that γ-globin expression in adult-derived erythroid cells can be influenced by the micro-environment, suggesting new potential targets for HbF induction. ..

    ..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. ..
