Abstract Hoxa9 and Meis1 are overexpressed in >70% of acute myeloid leukemia (AML) and associated with poor prognosis and survival. Hoxa9 and Meis1 interact with DNA and PBX to achieve transcription of differentiation-blocking genes. We tested transcriptional repression at Hoxa9-PBX-Meis1 genomic binding sites to induce differentiation in a model of human AML We designed a DNA-recognition strategy based on the known structure of the Hoxa9-PBX-DNA complex by fusing the DNA binding helices of Hoxa9 and PBX to create concise homeodomain fusion proteins that target the Hoxa9-PBX DNA recognition sequence. To confer transcription-repressing properties to the proteins, we attached a transcriptional repressor (sin3 interacting) domain and ectopically expressed this protein in Hoxa9-Meis1 immortalized murine progenitors. Introduction of this transcription repressor protein significantly enabled cell differentiation versus control (51.2% Mac-1high Gr-1high cells versus 11.3% for control). Multiple gene transcripts indicative of differentiation, such as GCSFR, myeloperoxidase, neutrophil elastase, and the calcium binding protein, S100A8, were also elevated in repressor-expressing cells. Furthermore, direct transcriptional targets of Hoxa9 (e.g. SOX2, CD34, FOXP1, FLT3R, DNAJC10) were down regulated in repressor-expressing cells. Importantly, a mutant repressor lacking the DNA-interacting amino acids did not affect transcription of Hoxa9 targets, demonstrating on-target specificity. Repressor-expressing cells also exhibited lower surface expression of c-Kit and Flt3 receptors and when transplanted into mice resulted in a significant increase in disease latency with a 94 day median latency versus 62 day latency for the control group (p value = 0.002). Our results demonstrate that site-specific DNA-targeting using homeodomain fusion proteins can enable AML cell differentiation and significantly increase disease latency.

Abstract DNA as life’s genetic material has been widely investigated around the world. In recent years, with the fiery researches on nanomaterials, it also plays an important role in the development of material science due to its extraordinary molecular recognition capability and prominent structural features. In this mini review, we mainly overview the recent progresses of DNA guiding self-assembled nanostructures and nanofabrication. Typical DNA tile-based assembly and DNA origami nanotechnologies are presented, utilizing the recent 3D topology methods to fabricate multidimensional structures with unique properties. Then the site-specific nanomaterials synthesis and nano-DNA recognition on different DNA scaffolds/templates are demonstrated with excellent addressability, biocompatibility and structural programmability. Various nanomaterials, such as metals, carbon family materials, quantum dots, metal-organic frameworks, and DNA-based liquid crystals are briefly summarized. Finally, the present limitation and future promising development directions are discussed in conclusion and perspective. We wish this review would provide useful information toward the broader scientific interests in DNA nanotechnology.
