4 In both cell lines celecoxib induced MRP4 and MRP5 over-expression at RNA and protein levels. Celecoxib ATP binding cassette subfamily C member 5 Homo sapiens
5 Cryoimmunoelectron microscopy showed increased MRP4 and MRP5 immunolabeling in celecoxib treated cells both at cytoplasmic level and along the plasma membrane. Celecoxib ATP binding cassette subfamily C member 5 Homo sapiens
6 Our findings, together with the results of clinical trials, may suggest that the combined use of celecoxib and drugs that are substrate for MRP4/MRP5 should be avoided. Celecoxib ATP binding cassette subfamily C member 5 Homo sapiens
