    1. Data suggests that an impaired capacity of eutopic and ectopic endometrial tissue to upregulate levels of HOXB4 during the proliferative phase may play a role in the pathogenesis of endometriosis and that further downregulation of HOXB4 may enhance ectopic implant invasiveness.

    4. HOXB4 knockout led to downregulation of P-glycoprotein, multidrug resistance-associated protein 1 and breast cancer resistance protein expression and PI3K/Akt signaling activity, suggesting that repression of HOXB4 might be a key point to reverse Multidrug resistance of K562/ADM cells.
