Dexamethasone (DEX), a synthetic corticosteroid, has been successfully used in clinical practice during paraquat (PQ) poisonings due to its anti-inflammatory activity, although, as recently observed, its effects related to de novo synthesis of P-glycoprotein (P-gp), may also strongly contribute for its healing effects.

Multidrug resistance type 1 P-glycoproteins (P-gp) and multidrug resistance associated proteins (MRP) were studied in differentiated primary human lung cells in culture, in comparison with permanent human lung cell lines and primary alveolar type II cells from rat lung.
AII cells exhibited low basal levels of mdr1b mRNA, that increased over time and after oxygen radical production induced by paraquat. mRNAs coding for antioxidative enzymes catalase (CAT), maganese superoxide dismutase (Mn-SOD) and copper/zinc superoxide dismutase (Cu/Zn-SOD) were not changed.

The AML-2/DX100 also showed various levels of resistance to daunorubicin and vincristine but was paradoxically sensitive to hydrogen peroxide (5-fold), t-butyl hydroperoxide (3-fold), and paraquat (2-fold) when compared to the drug-sensitive parental AML-2 cells (AML-2/WT).
