(J) Schematic model of working hypothesis. Npm1 loss causes (1) the premature aging of HSCs and (2) the activation of their mitochondria. This leads to (3) the activation of the inflammasome complex and the consequent (4) aberrant myeloid expansion. The progression of disease (5) is p53-depended. In the Npm1 cKO mouse model (gray), Npm1 loss increases p53 levels that trigger apoptosis and senescence, leading to bone marrow failure. Functional loss of p53 (red, Double KO) escapes these mechanisms, feeding a positive-feedback loop between inflammation and myeloid expansion, which results in blast accumulation and leukemic transformation.

A) Genomic DNA: Tf2 retrotransposons are flanked by LTRs, which are composed of U3, R, and U5 sequences. B) In WT cells, Fft2 and/or Fft3 position a nucleosome over the U3 and U3/R border. As a result, transcription initiates downstream of the LTR, just upstream of the protein coding region. C) The mRNA produced in WT cells is unable to support reverse transcription, an essential step in the retrotransposon lifecycle. D) In cells lacking or downregulating Fft2, Fft3, or both, a promoter and transcription start site in the LTR are exposed. E) The resultant mutant mRNA is capable of supporting reverse transcription. F) A self-primer in the R region hybridizes to the Primer Binding Site (PBS) in the U5. G) The tf2-encoding reverse transcriptase (RT) cleaves the self-primer from the rest of the mRNA and generates cDNA complementary to the U5 and R sequences while digesting the mRNA template. H) The RT and short cDNA transcript are able to hybridize at the 3' end of the mRNA, continuing reverse transcription and eventually producing a double stranded cDNA capable of reintegration into the genome. I) A putative role of Fft3 in restricting Tf2 integration is depicted. Gray ovals represent nucleosomes; RNAPII, RNA Polymerase II. Steps F-H based on mechanism elucidated by (Levin, 1995).
