Regulation of the Hoxa4 and
Hoxa5 genes in the embryonic mouse lung by retinoic acid and TGFbeta1: implications for lung development and patterning.
Hoxa5 undergoes dynamic DNA methylation and transcriptional repression in the adipose tissue of mice exposed to high-fat diet.
HOXA5.
HOXA5 overexpression in bone marrow CD34+ SCs and cord blood CD34+ CD38- cells resulted in a significant shift in myeloid differentiation [25].
Starting with 26 transcription factors identified as likely candidates, they eventually came down to just five (RUNX1, ERG, LCOR,
HOXA5 and HOXA9) that were both necessary and sufficient for creating blood stem cells.

HOXA5," Blood, vol.
MiR-130a contributes to angiogenesis by suppressing antiangiogenic homeobox gene GAX and
HOXA5 in endothelial cells.
miR-130a stimulates angiogenesis by inhibiting GAX and
HOXA5, while, miR-296 acts through the inhibition of hepatocyte growth factor-(HGF-) regulated tyrosine kinase [36].

Compromised
HOXA5 function can limit p53 expression in human breast tumours.
Of tumor samples taken from 30 women with breast cancer, 20 were devoid of the protein, called
HOXA5, says study coauthor Saraswati Sukumar, a molecular biologist at the Johns Hopkins Medical Institutions in Baltimore.
HOXA5 was selected because of multiple DMRs extending through the HOXA gene cluster.
Using the dCas9-SunTag-DNMT3A complex, researchers methylated a region of 4.5 kb residing the
Hoxa5 gene with fairly low off-target to on-target ratio [34].
