Furthermore, PCR analysis showed that the chromosome 11 breakpoint was at the APOA5/APOA4 locus at 11q23.3, which is associated with malignancy, and that the chromosome 22 breakpoint was at the SEPT5 intron 1 locus, which also plays a role in leukemogenesis through formation of a fusion gene with MLL.

Our findings demonstrate that the abnormal elevated expression of circAF4 regulates the cell growth via the circAF4/miR-128-3p/MLL-AF4 axis, which could contribute to leukemogenesis, suggesting that circAF4 may be a novel therapeutic target of MLL-AF4 leukemia.

Overall, this study suggests that the fetal liver Mll-AF4+ LSK cells are sensitive to direct exposure to inflammatory stimuli, especially poly(I:C); however, maternal immune activation induced by a single exposure to poly(I:C) is not sufficient to initiate MLL-AF4 leukemogenesis.

Aberrant fusion proteins involving the MLL histone methyltransferase (HMT) lead to recruitment of DOT1L, to a multi-protein complex resulting in aberrant methylation of histone H3 lysine 79 at MLL target genes, and ultimately enhanced expression of critical genes for hematopoietic differentiation, including HOXA9 and MEIS1, and as such defines the established mechanism for leukemogenesis in MLL-rearrangement (MLL-r) leukemias.
