The ecotropic viral integration site-1 gene (EVI1) encodes a zinc finger protein that functions as a transcriptional regulator of hematopoietic stem cell self-renewal and long-term multilineage repopulating activity. The mixed lineage leukemia gene (MLL) rearrangements [i.e. t(11q23)] occur at high frequency in pediatric acute myeloid leukemia (AML) patients with EVI1 overexpression, and EVI1 i...
The ecotropic viral integration site-1 (Evi1) locus was initially identified as a common site of retroviral integration in myeloid tumors of the AKXD-23 recombinant inbred mouse strain. The full-length Evi1 transcript encodes a putative transcription factor, containing ten zinc finger motifs found within two domains of the protein. To determine the biological function of the Evi1 proto-oncogene...
Central diabetes insipidus (DI) is a rare complication in patients with acute myeloid leukemia (AML), typically occurring in patients with abnormalities of chromosomes 3 or 7. The association between AML with monosomy 7 and DI has been described in a number of studies; however, DI has been rarely reported in cases of ectopic virus integration site-1 (EVI1)-positive AML with monosomy 7. The curr...
We identified a fusion between ETV6 on 12p13 and MDS1/EVI1 on 3q26 in a t(3;12)(q26;p13) found in two cases of myeloproliferative disorder. The resulting chimeric transcript consists of the first two exons of ETV6 fused to MDS1 sequences, which in turn is fused to the second exon of the EVI1 gene. It has recently been reported that MDS1 can be expressed in normal tissues both as a single gene a...
Myelodysplasia is a hematological disease in which genomic abnormalities accumulate in a hematopoietic stem cell leading to severe pancytopenia, multilineage differentiation impairment, and bone marrow (BM) apoptosis. Mortality in the disease results from pancytopenia or transformation to acute myeloid leukemia. There are frequent cytogenetic abnormalities, including deletions of chromosomes 5,...
UNLABELLED The involvement of the hepatitis B virus X (HBx) protein in epigenetic modifications during hepatocarcinogenesis has been previously characterized. Long noncoding RNAs (lncRNAs), a kind of epigenetic regulator molecules, have also been shown to play crucial roles in HBx-related hepatocellular carcinoma (HCC). In this study, we analyzed the key transcription factors of aberrantly expr...
Osteoporosis (OP) is considered a complex disease with a strong genetic impact, mainly affecting post-menopausal women and is also a common cause of fracture. Elucidating the molecular mechanisms that regulate the osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) is crucial to developing treatment strategies to combat OP. In the present study, we found that ectopi...
The reciprocal translocation t(1;3)(p36;q21) occurs in a subset of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML), which is frequently characterized by trilineage dysplasia, in particular dysmegakaryocytopoiesis, and poor prognosis. Previously, the breakpoint cluster region (BCR) at 3q21 was identified within a 60-kilobase (kb) region centromeric to the BCR of 3q21q26 syndrome ...
Inflammation is a hallmark of many important human diseases. Appropriate inflammation is critical for host defense; however, an overactive response is detrimental to the host. Thus, inflammation must be tightly regulated. The molecular mechanisms underlying the tight regulation of inflammation remain largely unknown. Ecotropic viral integration site 1 (EVI1), a proto-oncogene and zinc finger tr...
