Summary
Ecotropic viral integration site 1 (EVI1) drives acute myeloid leukemia (AML) by regulating leukemia stem cell self-renewal. Understanding EVI1
Area of Science:
- Hematology
- Molecular Biology
- Oncology
Background:
- Acute myeloid leukemia (AML) exhibits a cellular hierarchy driven by leukemia stem cells (LSCs).
- A shared transcriptional program between LSCs and hematopoietic stem cells (HSCs) is linked to poor AML prognosis.
- Ecotropic viral integration site 1 (EVI1) is a key regulator of stem cell properties and a potent oncogenic factor.
Purpose of the Study:
- To review the role of EVI1 in HSC self-renewal and leukemogenesis.
- To explore the molecular pathogenesis of EVI1-related leukemogenesis.
- To highlight the link between stem cell self-renewal and adverse outcomes in myeloid malignancies.
Main Methods:
- Literature review of EVI1 function in stem cell biology and AML.
- Analysis of gene expression profiles in LSCs and HSCs.
- Examination of molecular mechanisms underlying EVI1-mediated leukemogenesis.
Main Results:
- EVI1 is essential for HSC self-renewal and has stem cell-specific expression.
- EVI1 activation in AML is associated with extremely poor prognosis.
- EVI1 regulates various gene products involved in HSC function.
Conclusions:
- EVI1 plays a critical role in both HSC self-renewal and AML development.
- Shared stemness programs regulated by EVI1 contribute to AML progression and therapeutic resistance.
- Targeting EVI1 may offer therapeutic strategies for AML.

Multipotency of Hematopoietic Stem Cells
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...
Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Cancer Stem Cells and Tumor Maintenance
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
