RT-PCR and Western blot were not able to detect the two following ABC transporters, hMDR1 (P-gp) and hBCRP, involved in active transport in the hBMEC (human Brain microvascular endothelial cell). Whereas QTAP approach was able to detect but not quantify P-gp and BCRP in the cell membrane preparation.
The DDI (Drug-Drug interactions) guidelines (FDA and EMA) both quote these two transporter proteins as being highly relevant in ADME studies. Thus, our results reveal a major limitation for the use of the hBMEC cell line as in vitro human BBB model for the screening of drug candidates.
Key learning objectives
- Introduction to Quantitative Targeted Absolute Proteomics
- Application of QTAP in research
- Advantages of QTAP versus Western blot or other approaches
- Case study
