Abstract
Many transcription factors (TFs) function as tumor suppressor genes with heterozygous phenotypes, yet haploinsufficiency generally has an underappreciated role in neoplasia. This is no less true in myeloid cells, which are normally regulated by a delicately balanced and interconnected transcriptional network. Detailed understanding of TF dose in this circuitry sheds light on the leukemic transcriptome. In this review, we discuss the emerging features of haploinsufficient transcription factors (HITFs). We posit that: (a) monoallelic and biallelic losses can have distinct cellular outcomes; (b) the activity of a TF exists in a greater range than the traditional Mendelian genetic doses; and (c) how a TF is deleted or mutated impacts the cellular phenotype. The net effect of a HITF is a myeloid differentiation block and increased intercellular heterogeneity in the course of myeloid neoplasia.
期刊介绍：
The Annual Review of Pathology: Mechanisms of Disease is a scholarly journal that has been published since 2006. Its primary focus is to provide a comprehensive overview of recent advancements in our knowledge of the causes and development of significant human diseases. The journal places particular emphasis on exploring the current and evolving concepts of disease pathogenesis, as well as the molecular genetic and morphological changes associated with various diseases. Additionally, the journal addresses the clinical significance of these findings.
In order to increase accessibility and promote the broad dissemination of research, the current volume of the journal has transitioned from a gated subscription model to an open access format. This change has been made possible through the Annual Reviews' Subscribe to Open program, which allows all articles published in this volume to be freely accessible to readers. As part of this transition, all articles in the journal are published under a Creative Commons Attribution (CC BY) license, which encourages open sharing and use of the research.
