HOXA11

HOXA11

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. HOX11 is involved in regulating uterine development and is required for female fertility.

Of the 39 HOX genes, mutations in 10 HOX genes (HOXA1, HOXA2, HOXA11, HOXA13, HOXB1, HOXB13, HOXC13, HOXD4, HOXD10, and HOXD13) have been found to cause human disorders with variations in their inheritance patterns, penetrance, expressivity, and mechanisms of pathogenesis [1].

Two weeks after birth, a period that corresponds to the peak of the differentiation process in mice, Hoxa9, Hoxa10, Hoxa11, and Hoxa13 develop their characteristic spatial distribution throughout the Mullerian ducts: according to Taylor et al.
Hoxa gene patterning in PNDl controls resembled that in adult controls; that is, the highest levels of Hoxa9 were in the oviduct, Hoxa10 and Hoxa11 in the uterus, and Hoxa 13 in the cervix/vagina (Figure 4A).
On the day of birth (PNDl), we found that Hoxa10 Hoxa11, and Hoxal3 had an expression pattern similar to that on El9, whereas Hoxa9 was more highly expressed in the oviduct compared with the uterus and cervix/ vagina.
