Role of HOXA9 in leukemia: dysregulation, cofactors and essential ...
HOXA9 is a homeodomain-containing transcription factor that plays an important role in hematopoietic stem cell expansion and is commonly deregulated in acute leukemias. A variety of upstream genetic alterations in acute myeloid leukemia (AML) lead to overexpression of HOXA9, which is a strong predictor of poor prognosis.
Hox genes in evolution: protein surfaces and paralog groups
1997年4月1日 · Classifying Hox genes in Caenorhabditis elegans The small Hox cluster in the nematode C. elegans consists of four genes. In 3' to 5" order, they are ceh-13, 1in-39, mab-5 and egl-5 (Ref. 36). Even though a nonsegmented body sets apart the nematode from insects and vertebrates, genes in the complex specify anterior-posterior position-specific ...
Expression of Hox Genes in the Nervous System of Vertebrates
Studies on the patterns of expression, regulation and function of the vertebrate Hox gene family have played a key role in aiding our understanding of the basic ground plan of the CNS and processes that control how unique regional character is established and maintained in this complex organ system.
Studies have also shown that HOX genes appear to be important for normal T lymphocyte and activated natural killer cell function. Overexpression of Hox-b4 in trans-planted murine marrow cells results in a dramatic expansion of stem cells, …
THE ROLE OF HOX PROTEINS IN LEUKEMOGENESIS; INSIGHTS …
Increased and sustained Hox expression is found in a subset of leukemia with chromosomal translocations involving the MLL gene. 1–3 This observation suggested that the MLL gene product (Mixed Lineage Leukemia or Mll protein) might be involved in HOX regulation.
Biology of Hox Genes: Questions and Technological Challenges
2025年1月3日 · Hox genes are crucial in determining segmentation identity in developing embryos, which ultimately sets an anteroposterior body axis. Over a century of research has discovered the fundamentals of the Hox gene and protein function in …
