We thereby systematized differential expression patterns of eleven such genes which form the so-called NKL-code. Due to the developmental impact of NKL homeobox genes, these data suggest a key role for their activity in normal hematopoietic differentiation processes. On the other hand, the aberrant overexpression of NKL-code-members or the ectopical activation of non-code members have been frequently reported in lymphoid and myeloid leukemia\/lymphoma, revealing the oncogenic potential of these genes in the hematopoietic compartment. Here, I provide an overview of the NKL-code in normal hematopoiesis and instance mechanisms of deregulation and oncogenic functions of selected NKL genes in hematologic cancers. As well as published clinical studies, our conclusions are based on experimental work using hematopoietic cell lines which represent useful models to characterize the role of NKL homeobox genes in specific tumor types.<\/jats:p>","DOI":"10.3390\/cancers13081961","type":"journal-article","created":{"date-parts":[[2021,4,19]],"date-time":"2021-04-19T11:21:38Z","timestamp":1618831298000},"page":"1961","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["NKL-Code in Normal and Aberrant Hematopoiesis"],"prefix":"10.3390","volume":"13","author":[{"given":"Stefan","family":"Nagel","sequence":"first","affiliation":[{"name":"Department of Human and Animal Cell Lines, Leibniz-Institute DSMZ, German Collection of Microorganisms and Cell Cultures, Inhoffenstr. 7B, 38124 Braunschweig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"eaax9198","DOI":"10.1126\/science.aax9198","article-title":"A genome-wide transcriptomic analysis of protein-coding genes in human blood cells","volume":"366","author":"Uhlen","year":"2019","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1384","DOI":"10.1016\/j.cell.2020.08.030","article-title":"Unraveling Hematopoiesis through the lens of genomics","volume":"182","author":"Liggett","year":"2020","journal-title":"Cell"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"e104983","DOI":"10.15252\/embj.2020104983","article-title":"Interactions between lineage-associated transcription factors govern haematopoietic progenitor states","volume":"39","author":"Kucinski","year":"2020","journal-title":"EMBO J."},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1146\/annurev-immunol-032712-100024","article-title":"Transcriptional control of early T and B cell developmental choices","volume":"32","author":"Rothenberg","year":"2014","journal-title":"Annu.
