Abstract
cDNA encoding PDE10A (phosphodiesterase 10A) was cloned and a stable recombinant HEK-293 (human embryonic kidney-293) cell line expressing high levels of PDE10A was generated. Transient transfection of pCRE-Luc plasmid, harbouring the luciferase reporter gene under the control of CRE (cAMP-response element)-binding sequence, into the stable recombinant cell line, followed by treatment with PDE10 inhibitor, resulted in a dose-dependent increase in luciferase activity. This method provides a simple and sensitive cell-based assay for screening of PDE10 inhibitors for development of novel therapeutics for the treatment of neurological disorders.
