Abstract Although NPM1 gene mutations leading to aberrant cytoplasmic expression of nucleophosmin (NPMc+) are the most frequent genetic lesions in acute myeloid leukemia, there is yet no experimental model demonstrating their oncogenicity in vivo. We report the generation and characterization of a transgenic mouse model expressing the most frequent human NPMc+ mutation driven by the myeloid-specific human MRP8 promoter (hMRP8-NPMc+). In parallel, we generated a similar wild-type NPM trans-genic model (hMRP8-NPM). Interestingly, hMRP8-NPMc+ transgenic mice developed myeloproliferation in bone marrow and spleen, whereas nontransgenic littermates and hMRP8-NPM transgenic mice remained disease free. These findings provide the first in vivo evidence indicating that NPMc+ confers a proliferative advantage in the myeloid lineage. No spontaneous acute myeloid leukemia was found in hMPR8-NPMc+ or hMRP8-NPM mice. This model will also aid in the development of therapeutic regimens that specifically target NPMc+.

Abstract In this study, the anti-acute myeloid leukemia (AML) effects of Ziziphora clinopodioides Lam leaf aqueous extract conjugated cadmium nanoparticles (CdNPs) were compared with daunorubicin as a common chemotherapeutic drug. To synthesize CdNPs, Z. clinopodioides aqueous extract was combined with Cd(NO 3 ) 2 .4H 2 O. For analyzing CdNPs, SEM, UV-Vis. spectroscopy, X-ray powder diffraction and Energy dispersing X-ray spectroscopy, Fourier Transform Infrared techniques were used. In FE-SEM images of CdNPs, the diameter of particle dimension was on means of 26.78 nm. To survey the cytotoxicity and anti-AML effects of Cd(NO 3 ) 2 , Z. clinopodioides, Daunorubicin, CdNPs and MTT assay was used on the human AML cell lines. The IC50 of the cadmium nanoparticles was 168, 205 and 210 µg/mL against Murine C1498, 32D/FLT3-ITD and Human HL-60/vcr cell lines, respectively. In vivo study, CdNPs like daunorubicin ameliorated importantly (P≤0.01) the biochemical, WBC, RBC, inflammatory, platelet, stereological, histopathological and cellular-molecular parameters compared to the other groups. As mentioned, the cadmium nanoparticles had significant anti-AML effects. After approving the above eventuate in the clinical trial studies, these cadmium nanoparticles could be used in humans as a chemotherapeutic medicament for the treatment of AML. Additionally, the novel nanoparticles (Cd(NO 3 ) 2 and CdNPs) were good inhibitors of the α-glycosidase, and cholinesterase enzymes.
