After in vitro and clinical experiences with ATRA over a decade, the following mechanisms involved in development of the drug resistance have been proposed (Figure 4): 1) induction of accelerated metabolism of ATRA; 2) increased expression of cellular retinoic acid binding proteins (CRABPs); 3) constitutive degradation of PML-RAR[alpha]; 4) point mutations in the LBD of RAR[alpha] of PML-RAR[alpha]; 5) P-glycoprotein expression; 6) transcriptional repression by HDAC activity; 7) isoforms of PML-RAR[alpha]; 8) persistent telomerase activity; 9) expression of type II transglutaminase; and 10) topoisomerase II activity.
