NCOA1 and primary cutaneous T-cell non-Hodgkin lymphoma: As NCoA1 regulates retinoid signaling and several other nuclear receptors in addition to the steroid receptor, studies are in progress to address whether NCoA1 plays a role in drug resistance in CTCL and whether co-transfection of miR-22 potentiates the efficacy of anti-cancer therapies and drugs such as bexarotene and tazarotene and other treatment modalities.
