HOXA9

HOXA9

A gene on chromosome 7p15.2 that encodes a sequence-specific transcription factor of a developmental regulatory system, which provides cells with specific positional identities on the anterior-posterior axis and appears to be involved in gene expression, morphogenesis and differentiation.
 
Molecular pathology
A specific translation event, resulting in the fusion of HOXA11 and NUP98, which is associated with myeloid leukaemogenesis.

In studies to clarify epigenetic mechanisms in TGCTs, promoter methylation was shown in genes such as tumor suppressors APC, ARF, TP53, RARB2, BRCA1, RASSF1A, cell cycle regulator CCNA1, DNA repair genes such as MGMT and hMLH1, transcription factor HOXA9, and PRSS21, which encodes the protein testisin in testis cell maturation (30).

For example, HOXB3, HOXB4, and HOXA9 are abundantly expressed in HSCs, whereas HOXB8 and HOXA10 are expressed only in myeloid committed cells.

HOXA9 is a master transcription factor that controls a network of genes critical for hematopoiesis.
TET1 regulated the ability of tumor invasion also through the high mobility group AT-hook2 (HMGA2)/TET1/homeobox A9 (HOXA9) signaling pathway and was associated with poor prognosis in breast cancer.[sup][10],[11] HMGA2 is a chromatin remodeling factor that is highly expressed in ESCs and can regulate the expression of transcriptional enhancers.[sup][70] Compared with normal somatic cells, HMGA2 is overexpressed in most malignant tumors and promotes tumor invasion and metastasis.[sup][71] In gene expression array analysis, knocking down HMGA2 increased TET1 expression in breast cancer.
DNA methylation profiling of ovarian carcinomas and their in vitro models identifies HOXA9, HOXB5, SCGB3A1, and CRABP1 as novel targets.
