Aim:
To screen new drug for the treatment of acute promyelocytic leukemia, psoriasis and acne, high-throughput drug screening cell models marked by green fluorescent protein (GFP) have been established.
Methods:
Eight repeats of retinoic acid response element (RARE) were synthesized and cloned into a GFP expression vector. This construct was stably transfected into cells in vitro. Stable and sensitive cell clones with high copy numbers of RARE were selected by retinoic acid (RA) using fluorescence-activated cell sorting (FACS).
Results:
A cell line has been chosen to be high-throughput drug screening cell model. This model was shown with low background, high sensitive and good reproducibility, and was convenient and inexpensive.
Conclusion:
This drug screening cell model can be used for retinoic acid receptor target high-throughput drug screening.
