Homo sapiens | in attached breast epithelial cells, KDM3A expression is maintained at low levels by integrin signaling. Following detachment, integrin signaling is decreased resulting in increased KDM3A expression. Expression of either EGFR or MEK2DD decreases the levels of KDM3A in detached MCF10A cells | down |
Homo sapiens | in attached breast epithelial cells, KDM3A expression is maintained at low levels by integrin signaling. Following detachment, integrin signaling is decreased resulting in increased KDM3A expression. KDM3A protein levels are increased in attached MCF-10A cells treated with the EGFR inhibitor gefitinib. Detachment and loss of integrin and growth factor receptor signaling induces KDM3A expression | up |

malfunction | RNAi-mediated knockdown of KDM3A substantially reduces apoptosis following detachment and, conversely, ectopic expression of KDM3A induces cell death in attached cells. Knockdown of Kdm3a enhances metastatic potential in a mouse model of breast cancer metastasis. Defective KDM3A expression in human breast cancer cell lines and tumors. Kdm3a knockdown significantly increases the number of cells that survived in the mouse lung relative to the control NS shRNA | Homo sapiens |
malfunction | switching off the enzyme in cancer cells increases their ability to move around the body | Homo sapiens |

physiological function | epithelial cells that lose attachment to the extracellular matrix (ECM), or attach to an inappropriate ECM, undergo a specialized form of apoptosis called anoikis. Anoikis has an important role in preventing oncogenesis, particularly metastasis, by eliminating cells that lack proper ECM cues. Histone H3K9 demethylase KDM3A promotes anoikis by transcriptionally activating pro-apoptotic genes BNIP3 and BNIP3L. KDM3A demethylates H3K9me1/2 to stimulate expression of one or more pro-apoptotic genes. KDM3A promotes anoikis through transcriptional activation of BNIP3 and BNIP3L, which encode pro-apoptotic proteins. Identification of KDM3A as an anoikis effector in breast cancer epithelial cells, overview | Homo sapiens |
